David Deutsch and Lulie Tanett Violated Reasonable Expectations

When the harassment started, I didn’t expect that David Deutsch (DD) or Lulie Tanett (LT) were involved. When I caught Andy B (linked together his many fake identities), I emailed DD and LT about it, and I thought they’d be helpful and reasonable. I expected a very different reaction than I got.

What DD and LT have done has surprised me. That actually made it harder to deal with. If I knew what they were like in the first place, I would have handled the situation differently. I went out of my way to give them lots of chances for private discussion. I responded slowly to the problems to give them many chances and months to see it’s a serious public issue and change their behavior. I didn’t go into this knowing what was actually going on. I shared information as I figured out new things and that’s made my explanations longer and more complex.

Why was I surprised? Well they just left without comment. They didn’t leave in an explicitly negative way. They never said they weren’t speaking to me. We didn’t part ways with a fight. Nothing in particular happened. Our conversation frequency dwindled over time. I initiated some problem solving, but I wasn’t pushy about it and gave them time and space. Months passed and at some point they didn’t come back. That’s all. That didn’t give me much reason to think they hated me or wanted me harmed.

There was no conversation where I had any reason to think it was the last one. By the time I knew things were over, they’d been over for months. (And by the time I knew DD and LT actually weren’t speaking to me – the current situation – I now estimate that they hadn’t been for multiple years. That’s something they did on their own, unilaterally, without informing me, and with no specific or clear cause.) They never even said bye. I thought we were still trying, gradually over time, and eventually I realized that they weren’t.

I thought our old friendships would still mean something when a criminal attacked. And it’s not like I had done anything wrong. I hadn’t wronged DD or LT. I hadn’t done some sort of mean action to hurt them. I hadn’t knowingly violated their consent. And they never complained “Hey wait, that wasn’t OK, you accidentally violated my consent”.

I thought crimes were a serious matter and that people would set aside petty stuff when crime was at stake. I didn’t know that DD and LT were so far gone not to do that and/or were never actually very anti-crime (just anti crimes against their own tribe).

I thought they were doing their own things, separate from me, and that when there was an emergency involving crime that would take precedence over whatever mild grudges or negative feelings had lasted through years of not interacting. Time heals all wounds, right? Why would they still be super mad – mad enough to have a tribalist attitude and side with crime – after years with no negative interactions?

The thing DD lied about is a key point. He lied that he told me several times that he didn’t want to hear from me. But he never told me that and I had no idea he felt that way. That’s key context. He’s lying that I’m violating his requests, when actually he was violating my reasonable expectations (which is misleading to observers) even before he overtly lied about me. I had a reasonable expectation that he would respond appropriately when his fan was committing crimes partially in DD’s name. (One of Andy B’s main complaints, and motivations for harassment, is that he sees me as DD’s enemy.) DD also wouldn’t respond when Dennis Hackethal plagiarized both of us, or when someone impersonated DD and wrote comments literally in DD’s name, or when Andy B created and owned the BoI subreddit (DD wouldn’t disown that or distance himself from it in any way).

I thought I was telling DD and LT about a serious problem in their community that was bad for them. I thought they’d want to ban him from their community and keep their distance from a dangerous person. Instead they embraced Andy B, tweet with him, and continue to have a toxic community culture that does things like lie, libel, and spread hateful gossip.

I thought DD cared about his career and reputation, and would want to stay out of the mud, and would appreciate the warning about the mud getting on him. I thought it was neglect not malice. I was wrong though. After nearly a decade of going our separate ways, DD seems willing to take substantial risks with his public reputation for the purpose of trying to hurt me. He can’t or won’t let anything go, nor specify what exactly he’s so upset about or what he wants or doesn’t want. (I literally don’t know what actions to take to please or appease him so that he’d stop the harassment campaign; he won’t say; maybe there are none.)

DD’s and LT’s behavior, like fully ghosting me about crimes connected with them, and tweeting with Andy B after he was caught, has been really shocking. It completely violated my expectations based on how we left things (as well as my expectations about basic human decency and civilized behavior from them).

I’ve been going back and reading old stuff because I was shocked by their behavior and I wanted to know what happened. Did they change a lot since we last spoke much, or did I miss something in the past? The answer, in short, is that I missed stuff in the past. The old discussions are full of warning signs about their irrationality that I can see now but missed before.

DD and LT are the only people involved in the harassment that I actually knew well. It makes some sense that I’m still on their mind. But I met Sarah a long time ago but never knew her very well, and she really shouldn’t still care about me. Most CritRats I knew less well than Sarah. Why would people I never knew at all, or never knew well, hold multi-year grudges and be super hateful? There’s something really wrong there (I think their community is really toxic). And to the extent I can get any reasons from them, they say stuff like that I’m rude and that I criticized their hero DD. So what? All public figures have rude detractors on the internet, who are mostly ignored or mocked a little bit, but generally no one cares much. Even if that were true about me, why would it even matter? The people who hate and harass me are revealing, by their behavior, that they think I’m super important. They act like my opinions will somehow determine DD’s fate. They treat me like DD’s peer, and like one of the few intellectuals in the world who matters. They seem to see me like a threat to DD, a high status power player with a big following, or else why would they care? If they don’t like me and think I don’t matter, they wouldn’t be so concerned with my opinions.

I’ve posted negative blog posts about (for example) Sam Harris, but none of his fans bother me about it. I don’t even get mild pushback (they don’t seem to notice or care), let alone harassment. If I actually went to Harris’ subreddit and criticized him there, I’d get negative reactions, but all I’d have to do is stop posting on his subreddit and they’d forget about me and leave me alone. Why? Because Harris has many critics and even haters, but most are not influential and most fans don’t regard them as important. If I had 100k YouTube followers and criticized Harris, it’d get more of a reaction, but I don’t have that. Yet DD’s community treats me like I have a few million YouTube followers, or whatever the equivalent is for blog readers.

Misquotes by David Deutsch

I’ve discovered that David Deutsch (DD) is an unreliable quoter. His book The Beginning of Infinity (BoI) contains many serious quotation errors, and he has misquoted elsewhere too.

For context, DD and I were close associates for a decade. I helped with BoI for 7 years and wrote over 200 pages of comments, suggestions and edits on drafts of the book. I learned a lot from him but I trusted his scholarship too much. I promoted his books. I was wrong about him and his books in multiple ways. My mistake. I retract my previous endorsements and recommendations of DD’s books. That doesn’t mean the books are awful or shouldn’t be read, but I no longer want to promote them myself. There are good ideas mixed in, but be wary of major problems.

Misquotes in The Beginning of Infinity

Block quotes are from BoI unless otherwise stated.

I think there will certainly not be novelty, say for a thousand years. This thing cannot keep going on so that we are always going to discover more and more new laws. If we do, it will become boring that there are so many levels one underneath the other . . . We are very lucky to live in an age in which we are still making discoveries. It is like the discovery of America – you only discover it once.
The Character of Physical Law (1965)

That’s different than what Feynman wrote. DD changed the words “perpetual novelty” to “novelty”. DD also changed “keep on going” to “keep going on”. (More details.)

Behind it all is surely an idea so simple, so beautiful, that when we grasp it – in a decade, a century, or a millennium – we will all say to each other, how could it have been otherwise?
John Archibald Wheeler, Annals of the New York Academy of Sciences, 480 (1986)

What Wheeler actually wrote was "Behind it all is surely an idea so simple, so beautiful, so compelling that when–in a decade, a century, or a millennium–we grasp it, we will all say to each other, how could it have been otherwise?”. DD deleted “so compelling” and moved “we grasp it” to before the dashed part. (More details.)

As the physicist Richard Feynman said, ‘Science is what we have learned about how to keep from fooling ourselves.’

Feynman didn’t say that. It’s not even a documented quote with some changes. It seems made up with no original source or evidence.

I checked the web and some Feynman books and speeches. It’s likely that the misquote started in 2000 in the article Magical Thinking (my thanks to Justin Mallone for finding that article), which paraphrased Feynman that way without using quote marks or giving a source. Unfortunately, the wording made it sound like it was an actual quote, so I think people started spreading it as a quote. Then DD probably got the misquote from an unreliable webpage and put it in his book without trying to find a primary source or telling his readers which unreliable secondary source he used. There are now two books which give this quote and cite it to as quoted in BoI. There’s also a book which gives the quote with a footnote saying that the author was unable to find a source for the quote (then don’t put it in your book!).

Feynman said some similar ideas in Cargo Cult Science, but the wordings are different. DD didn’t take the quote from there and add one or two errors (like he did with some other quotes, where you can tell that he’s quoting a specific thing incorrectly). It’s too different to have come from that speech.

Popper wrote:

The inductivist or Lamarckian approach operates with the idea of instruction from without, or from the environment. But the critical or Darwinian approach only allows instruction from within – from within the structure itself . . .

I contend that there is no such thing as instruction from without the structure. We do not discover new facts or new effects by copying them, or by inferring them inductively from observation, or by any other method of instruction by the environment. We use, rather, the method of trial and the elimination of error. As Ernst Gombrich says, ‘making comes before matching’: the active production of a new trial structure comes before its exposure to eliminating tests.
The Myth of the Framework

DD ends the first sentence of the second paragraph with “without the structure” and then a period. Instead of a period, Popper had a comma there and continued the sentence. Then, the rest of that paragraph that DD quotes is actually from a different section of the book. DD combined sentences from different places in the book and presented them as one paragraph with no ellipsis or square brackets to indicate a modification.

And DD left out the words “In fact,” before “I contend”. DD also put an ellipsis at the end of the first paragraph when that should be a period. There are no omitted words there. The paragraph ends there and DD continues without skipping a paragraph. DD also left out Popper’s italics.

A similar misquote also appeared on the Taking Children Seriously (TCS) website (mirror). DD co-founded TCS with Sarah Fitz-Claridge and she’s my best guess at the author of that misquote, though it could have been DD. Either way, he has responsibility for what it says on the official website of the movement he co-founded (particularly for pages, like this one, with no author specified).

Judging by the similarities, the misquote in BoI was likely based on the TCS website misquote. Even when a secondary source is accurate, it’s problematic to take a secondary source quote and then edit it without checking the original. When you do that, you’re making edits without knowing the original context and wording, so you aren’t in a good enough position to judge what edits are OK.

(More details about the TCS website version of the misquote.)

Thanks to Dec for telling me that this misquote is also in BoI after I wrote about the version from the TCS website.

As the physicist Stephen Hawking put it, humans are ‘just a chemical scum on the surface of a typical planet that’s in orbit round a typical star on the outskirts of a typical galaxy’.

This quote seems to be made up based on a similar Hawking quote about “chemical scum” from the 1995 TV program (Reality on the Rocks: Beyond Our Ken by Ken Campbell (IMBD, trailer)). Interestingly, DD had quoted it correctly in The Fabric of Reality as “The human race is just a chemical scum on a moderate-sized planet, orbiting round a very average star in the outer suburb of one among a hundred billion galaxies.” I didn’t find the original video, but it’s quoted that way in various places online that aren’t based on DD’s writing. (Some sources have “around” instead of “round”, which is an understandable difference given how similar those words can sound when spoken out loud.)

It seems that DD made up this misquote for his 2005 TED talk and then based the quote in BoI on his talk. Alan Forrester checked the books The large scale structure of space-time, A Brief History of Time, The Grand Design, The Nature of Space and Time and The Universe in a Nutshell, but found that none contain the word “scum”. And I can’t find any online sources for Hawking ever saying the BoI version of the quote (whereas with the The Fabric of Reality version, I easily found other online sources).

This misquote doesn’t seem fully accidental. DD changed the quote to be more elegant and catchy by repeating “typical” three times. I’ve noticed that many of DD’s misquotes involve changing text to sound nicer.

(More details.)

[Horgan believed] that science has the ability to ‘resolve questions’ objectively […]

Horgan actually wrote “Scientists have the ability to pose questions and resolve them in a way that critics, philosophers, historians cannot.” DD changed Horgan’s words “resolve them” to “resolve questions”, which is wrong without using square brackets to indicate an edit. (More details.)

The issue of what exactly needs to be explained in an ‘appearance of design’ was first addressed by the clergyman William Paley, the finest exponent of the argument from design. In 1802, before Darwin was born, he published the following thought experiment in his book Natural Theology.

It’s unclear what, if anything, “appearance of design” is a quote from, but it’d be understandable if a reader believed it was a quote of Paley in Natural Theology. But it’s not in that book.

[Paley wrote:]

The inference we think is inevitable, that the watch must have had a maker . . . There cannot be design without a designer; contrivance without a contriver; order without choice; arrangement without anything capable of arranging; subserviency and relation to a purpose without that which could intend a purpose; means suitable to an end . . . without the end ever having been contemplated or the means accommodated to it. Arrangement, disposition of parts, subserviency of means to an end, relation of instruments to a use imply the presence of intelligence and mind.

DD changed the words “any thing” to the word “anything” and changed “an use” to “a use”. DD also quoted from both chapters 1 and 2, but presented it as single paragraph with ellipses. DD also removed a comma near the end before “imply the presence of intelligence and mind” which helped the reader understand the text. (DD edited other punctuation too, but this punctuation edit stood out to me because it’s significantly worse than the original.) (More details.)

As Hawking once put it, ‘Television sets could come out [of a naked singularity].’

Thanks to Alan Forrester for looking into this quote at my request. He was unable to find Hawking saying this. He searched the web and the following books: The large scale structure of space-time, A Brief History of Time, The Grand Design, The Nature of Space and Time and The Universe in a Nutshell.

As Hofstadter remarked, ‘In retrospect, I am quite amazed at how much genuine intelligence I was willing to accept as somehow having been implanted in the program . . . It is clear that I was willing to accept a huge amount of fluidity as achievable in this day and age simply by putting together a large bag of isolated tricks, kludges and hacks.’

Hofstadter’s actual paragraph ends with “a large bag of isolated tricks-kludges and hacks, as they say.” DD’s punctation edits changed the meaning. Hofstadter said “isolated tricks” and then gave “kludges and hacks” as a rewording of “isolated tricks”. DD changed it to a list of three things, “tricks, kludges and hacks” and made it sound like the modifier “isolated” applies to all three, whereas in the original it applied only to “tricks”. As a list, it means that all three things were put together. In the original, it says they put together tricks, and then provides the additional information that the tricks could be characterized as kludges and hacks as people (informally) say.

Thanks to Dec for bringing up this misquote.

Representative Roger Q. Mills of Texas complained in 1882, ‘I thought . . . that mathematics was a divine science. I thought that mathematics was the only science that spoke to inspiration and was infallible in its utterances [but] here is a new system of mathematics that demonstrates the truth to be false.’

This text is available in the Congressional Record. DD changed the words "by inspiration" to "to inspiration". It’s also misleading that where DD wrote “[but]”, with no ellipsis, he skipped multiple sentences and continued with text from a different paragraph.

DD likely copied this misquote from Fair Representation without telling his readers that he was trusting a secondary source without fact checking it, and without letting readers know which secondary source he was using.

Thanks to Justin Mallone for looking this up at my request.

Before Blackmore and others realized the significance of memes in human evolution, all sorts of root causes had been suggested [...] [T]here is the ‘Machiavellian hypothesis’ that human intelligence evolved in order to predict the behaviour of others, and to fool them. […] Blackmore’s ‘meme machine’ idea, that human brains evolved in order to replicate memes, must be true.

At first I read “Machiavellian hypothesis” as a quote of Blackmore from her book The Meme Machine that DD mentioned earlier and included in his bibliography. If so, it's a misquote. That phrase isn’t in her book.

But maybe “Machiavellian hypothesis” is merely meant to be the name of a hypothesis. If so, it’s the wrong name. The correct name is "Machiavellian Intelligence”, as one can find out from Blackmore’s book or Wikipedia. Blackmore has an index entry for “Machiavellian Intelligence” and cites two books with “Machiavellian Intelligence” in their title. She also writes “An influential version of social theory is the ‘Machiavellian Intelligence’ hypothesis (Byrne and Whiten 1988; Whiten and Byrne 1997).”. It appears that DD read her book, misremembered the name of the hypothesis, didn’t check it, and put quote marks around it. (More details.)

The more important fundamental laws and facts of physical science have all been discovered, and these are now so firmly established that the possibility of their ever being supplanted in consequence of new discoveries is exceedingly remote . . . Our future discoveries must be looked for in the sixth place of decimals.
Albert Michelson, address at the opening of the Ryerson Physical Laboratory, University of Chicago, 1894

The source for this, which DD didn’t specify, is the book Light Waves and Their Uses (1903) by Albert Michelson. The speaker wrote down what he said in his own book. Michelson wrote:

Many other instances might be cited, but these will suffice to justify the statement that "our future discoveries must be looked for in the sixth place of decimals."

DD incorrectly quoted this as Michelson saying “[o]ur future discoveries must be looked for in the sixth place of decimals” himself, when Michelson actually had it in quote marks and talked about that statement. Deleting quote marks within a quote is misquoting. (More details.)

For example, as I wrote in The Fabric of Reality:

Consider one particular copper atom at the tip of the nose of the statue of Sir Winston Churchill that stands in Parliament Square in London. Let me try to explain why that copper atom is there. It is because Churchill served as prime minister in the House of Commons nearby; and because his ideas and leadership contributed to the Allied victory in the Second World War; and because it is customary to honour such people by putting up statues of them; and because bronze, a traditional material for such statues, contains copper, and so on. Thus we explain a low-level physical observation – the presence of a copper atom at a particular location – through extremely high-level theories about emergent phenomena such as ideas, leadership, war and tradition.

There is no reason why there should exist, even in principle, any lower-level explanation of the presence of that copper atom than the one I have just given. Presumably a reductive ‘theory of everything’ would in principle make a low-level prediction of the probability that such a statue will exist, given the condition of (say) the solar system at some earlier date. It would also in principle describe how the statue probably got there. But such descriptions and predictions (wildly infeasible, of course) would explain nothing. They would merely describe the trajectory that each copper atom followed from the copper mine, through the smelter and the sculptor’s studio and so on . . . In fact such a prediction would have to refer to atoms all over the planet, engaged in the complex motion we call the Second World War, among other things. But even if you had the superhuman capacity to follow such lengthy predictions of the copper atom’s being there, you would still not be able to say ‘Ah yes, now I understand why they are there’. [You] would have to inquire into what it was about that configuration of atoms, and those trajectories, that gave them the propensity to deposit a copper atom at this location. Pursuing that inquiry would be a creative task, as discovering new explanations always is. You would have to discover that certain atomic configurations support emergent phenomena such as leadership and war, which are related to one another by high-level explanatory theories. Only when you knew those theories could you understand why that copper atom is where it is.

In addition to checking this using ebooks, I also compared hardback copies of both books. It’s FoR pp. 22-23 and BoI pp. 109-110.

DD quotes “understand why they are there” but the original reads “understand why it is there”. DD changed the words “it is” to “they are”.

DD quotes "Pursuing that inquiry”, but FoR says “this inquiry”. DD changed the word “this” to “that”.

DD quotes “understand why that copper atom is where it is”. DD omitted the word “fully”. The original said “understand fully why”.

DD wrote “[You]” in BoI, which is an incorrect use of square brackets. He skipped two sentences and should have used an ellipsis. And it says “You” in the original, so he shouldn’t put it in square brackets since it isn’t modified. Square brackets can only replace an ellipsis when the text in square brackets replaces/summarizes/paraphrases all the skipped text, but the word “You” doesn’t replace the skipped sentences.

The italics “why” and “what it was” are not italicized in FoR.

The ellipsis DD used in “studio and so on . . . In fact” is incorrect because the original had a period after “so on”. There should be four dots there (one for the period, and three for the ellipsis), not three dots.

DD doesn’t even quote himself accurately.

Other Misquotes

In The Fabric of Reality, DD wrote:

Mystery is part of the very concept of time that we grow up with. St Augustine, for example, said:

What then is time? If no one asks me, I know; if I wish to explain it to one who asks, I know not. (Confessions)

This quote has some word changes compared to the edition of Confessions that I checked. However, there are other English translations, so it could be an accurate quote of one of those. DD didn’t say which translation he used, which is more problematic than usual when quoting a particular translation rather than quoting something with a single, unambiguous wording that could be looked up.

DD wrote in Not Merely the Finest TV Documentary Series Ever Made:

As Karl Popper put it, we humans can “let our ideas die in our place.”

I found Popper saying something similar three times, but he didn’t use that wording. I think DD relies on his memory for this quote, instead of checking a source. He’s quoted it different ways in different places (e.g. with “theories” instead of “ideas” in Why It’s Good To Be Wrong and BoI). DD should get quotes from sources instead of putting quote marks around what he believes he remembers someone writing.

Popper said similar things in The Myth of the Framework (“By criticizing our theories we can let our theories die in our stead.”), In Search of a Better World (“Now we can let our theories die in our place.”), and Natural Selection and the Emergence of Mind (“Let our conjectures, our theories, die in our stead!”).

DD’s associate Chiara Marletto also misquoted Popper as saying "let our ideas die in our place.”.

DD’s associate Sarah Fitz-Claridge misquoted William Godwin and intentionally sanitized a quote about slavery. She gives “The condition of a … slave in the West-Indies, is in many respects preferable to that of the youthful son of a free-born European. The slave is purchased upon a view of mercantile speculation; and, when he has finished his daily portion of labour, his master concerns himself no further about him. But the watchful care of the parent is endless. The youth is never free from the danger of grating interference.”. She misquoted by changing the words "of its grating" to “of grating”. And she sanitized the 1797 quote by changing "negro-slave" into "... slave”. (I think that’s an incorrect use of an ellipsis, too.) Also, the quote is horrible because it downplays how bad slavery was, so it’s disturbing that Fitz-Claridge liked the quote enough to highlight it.

Fitz-Claridge also misquoted The Myth of the Framework. It’s some of the same Popper material misquoted in BoI and on the TCS website, but misquoted differently. This time, Fitz-Claridge changed “that” to “which” and got the page numbers wrong. (More details in the second update.)

Smaller Issues

DD frequently doesn’t give sources for quotes which makes it harder to check their accuracy. By leaving out sources, he’s asking his reader to trust him. But he made many quoting errors, so that trust would be misplaced.

DD repeatedly writes “X … Y” when X and Y are from different paragraphs or even different sections of a book. This is misleading. He also does it when X is a complete sentence, which makes it look like X is not a complete sentence.

DD frequently changes capitalization and punctuation without square brackets to indicate the change. DD capitalizes stuff to make it look like the start of a sentence when it isn’t (both at the start of a quote or after an ellipsis). DD also puts periods inside the quote marks after quoting a partial sentence, which makes it look like that was the end of the sentence when it wasn’t. DD also repeatedly puts a space then an ellipsis after a sentence ends, which should be a period then ellipsis but he changed the period to a space. So he makes stuff look like the start or end of a sentence when it isn’t, and then other times he makes stuff look like it’s not the end of a sentence when it is.

DD doesn’t appear to have a consistent policy for periods going inside or outside of quotes. E.g. I searched an electronic copy of BoI and found 188 instances of a single close quote followed by a period, and 88 instances of a period followed by a single close quote (and 3 instances of period, single close quote, and period again, which all involved a number, ellipsis, close quote, then period). DD often ends quotes with a period inside the quotation marks when the original sentence doesn’t end there, but other times he puts the period outside the quotation marks, and I don’t know why. DD is also inconsistent about italicizing quotes the same way they are in the original.

There are standard guidelines for how to do quotations, which DD violates, in addition to the larger misquote issues I presented above. For example, Working with Quotations, from Suny Empire State College, says:

Remember that when you do choose to use direct quotations, you need to retain the exact wording, spelling, capitalization, and punctuation of the original source.

DD went to both Oxford and Cambridge. I don’t think they teach lower standards than state colleges, and in any case he hasn’t followed their guidelines. For example, this Guide for authors and editors from the Oxford University Press says:

Quoted matter must reflect the original source exactly in spelling, punctuation, and capitalization. Please double-check all quotations against the sources from which you have taken them to ensure that you have copied accurately.

It must be possible for the reader to identify the work from which a quotation has been taken.

The University Of Oxford Style Guide says “Place any punctuation which does not belong to the quote outside the quotation marks (except closing punctuation if the end of the quote is also the end of the sentence).”

The Cambridge Editorial Style Guide says “A full stop is used outside the quotation mark if the quote is only part of a sentence.” and “Always source quotations”.

Taking Credit from Karl Popper

There’s another scholarship issue in DD’s books. I was horrified to discover that Karl Popper’s name is only in The Fabric of Reality (FoR) chapter 3 two times. That chapter is focused on sharing Popper’s ideas. But it doesn’t give adequate credit. In particular, the diagrams (3.1, 3.2, 3.3) are clearly based on Popper’s diagrams in Objective Knowledge, but DD never tells the reader that they’re modified from Popper. (More details.)

DD has presented himself as very humble and modest. He’s claimed multiple times to be only footnotes to Popper (which comes off as exaggerated modesty, rather than convincing his fans that it’s actually true). But DD has simultaneously misled readers to believe he accomplished much more than he did, e.g. in FoR ch. 3. This is a pattern. For example, in a 2016 paper, The logic of experimental tests, particularly of Everettian quantum theory, DD wrote:

An important consequence of this explanatory conception of science is that experimental results consistent with a theory T do not constitute support for T. That is because they are merely explicanda. A new explicandum may make a theory more problematic, but it can never solve existing problems involving a theory (except by making rival theories problematic – see Section 3). The asymmetry between refutation (tentative) and support (non-existent) in scientific methodology is better understood in this way, by regarding theories as explanations, than through Popper's (op. cit.) own argument from the logic of predictions, appealing to what has been called the ‘arrow of modus ponens’. Scientific theories are only approximately modelled as propositions, but they are precisely explanations.

This passage misleads readers into believing that DD improved on Popper by making a better argument focused on explanations instead of on the logic of predictions. Most readers would be surprised to discover that Popper made both arguments. Popper did make the logic of predictions argument (which is less important but was worth making too) but also made the other argument that DD is implying is his own original work. DD made some original contributions to epistemology, but not this one.

You can search Popper’s Conjectures and Refutations (C&R) for words like "tentative", "explanation", and "support" to see that DD is less original than he implies. Popper also covers these issues in other books. I’ll give one example from C&R:

For a scientific theory—an explanatory theory—is, if anything, an attempt to solve a scientific problem, that is to say, a problem concerned or connected with the discovery of an explanation.[6]

This clearly shows that Popper viewed scientific theories as explanatory theories. DD didn’t come up with the idea that scientific theories are explanations. The footnote at the end of that quote refers readers to more of Popper’s writing. Popper talked about explanation often. Popper also came up with the asymmetry between refutation (tentative) and support (non-existent). Popper emphasized refutation, said it was only tentative, and is also the person who challenged thousands of years of philosophical tradition by arguing that support is non-existent. Popper drew multiple major distinctions between negative and positive approaches to epistemology.

DD also gets other people to praise him while he presents himself as humble. For example, his TCS co-founder Sarah Fitz-Claridge (SFC) wrote that Popper invented a philosophy of science and that David Deutsch and his TCS philosophy had extended Popper’s epistemology to apply outside of science. (SFC probably wrote that. It’s on an official TCS page, but doesn’t specify the author, so it could have been written by DD.) That’s a major misrepresentation. Popper was seeking a general theory of knowledge, and said so, and applied it outside of science. (More details.)

DD has gotten his associates to praise him as e.g. having “the greatest mind ever”. SFC believes that DD made major improvements on Popper, and so do many of DD’s fans. I don’t believe it’s an accident that many people overestimate DD in ways similar to his co-founder who publicly promotes him. It looks like a strategy where DD plays humble while having other people say things that would sound arrogant coming from him. (More details.)

In 2012, SFC wrote to the official Fabric of Reality discussion group (archive of FoR posts) (my italics):

In my view it would be much more accurate to say that David has the greatest mind ever to have existed. His thinking is breathtakingly logical and brilliant. His ideas have changed the world and will do so even more profoundly in the future. I have never met anyone more pure, more truth-seeking and more open to criticism than David.

In 2000, SFC wrote to TCS list (my italics):

So really, people should not speak of Popper, but of Deutsch, because it was David who came up with the link between Popper's ideas and educational theory.

Note that DD has a history of secretly ghostwriting stuff which SFC then claims to be the author of. (Source: DD’s friend. He or she was friends with DD before DD turned 18 and they’re still friends now, over 50 years later. He or she had many discussions about TCS, Popper and more with DD and SFC. DD introduced me to the friend and I had some discussions with him or her.) Full disclosure: In the past, I’ve posted a few things that DD wrote, but under my own name, with his permission and approval. I did this when (as best I remember) I wanted to share something good that he told me, which I thought would benefit the world, but he didn’t want to share it himself and wouldn’t let me post it and attribute it to him or to an anonymous person, but he would let me post it under my name without attributing it to anyone. Here’s an example that I remember (I think it was the most significant, memorable instance). More often, I wrote stuff myself that was based on things DD told me, and he didn’t want credit but was happy for me to say it. At other times, DD helped edit my writing and a sentence or two of his ended up in the final version without credit (he didn’t want credit). DD had substantial influence over some of my early writing, and he also has had substantial influence over some of SFC’s writing that he didn’t fully ghostwrite.


I was mistaken about how good DD’s books are. They’re worse than I thought. I still think there is significant value in those books, but you can’t trust DD’s scholarship. Besides distrusting direct quotes given by DD, you should also distrust paraphrases or summaries of what other people said or thought. You have to check things yourself if you actually want to know. DD is too unreliable. And don’t use DD as a secondary source. Don’t spread quotes that DD quoted; quote directly from the original source or don’t use it. Some people are spreading his misquotes (they’ve even been repeated in books).

FYI, I don’t think DD is especially bad at quoting compared to others. Lots of books and academic articles have major errors related to quotes, paraphrases, cites or facts. But for a book to be considered great, it should do better. In the world today, you shouldn’t trust authors with quotes or facts by default. You should be suspicious by default unless an author earns more trust. Many people believe DD has earned a lot of trust (including me in the past), but they’re mistaken.

I apologize for encouraging people to respect and trust DD more than he merits. I know I played a role in that.

DD’s misquote problem also helps contextualize his recent mistreatment of me. How could a super rational, great person act like that? The answer is that he he’s actually a deeply flawed person with some good traits mixed in as special exceptions.

DD once got very upset with me for questioning a Godwin quote he sent me in a private discussion. He’d sent it without a specific source and I couldn’t find the quote by searching the book. It turned out that he’d quoted an obscure first edition but I was searching the third edition. He should have praised me for looking for errors instead of getting defensive and lashing out at me. Good scholars don’t expect to be trusted and don’t mind being questioned or challenged. Even though he didn’t misquote in that instance, DD’s irrational attitude was a warning sign that DD might be a misquoter. I failed to recognize the full problem and I didn’t go fact check his books at that time (2011).

BoI has an errata page (mirror) which documents a bunch of errors in the book. They are mostly factual errors, and the number and severity should concern readers. Despite all the misquotes in the book, there are currently no misquotes on the errata page, which says something about how little fact checking the book has been getting (there are probably a bunch of other errors that no one has found yet).

I will edit my book recommendation articles to warn people about DD’s misquotes. I will also take down the beginningofinfinity.com website that promotes BoI and put a warning there about DD’s misquotes.

Update, 2021-07-12: In a 1985 physics paper in a prestigious, peer-reviewed journal, David Deustch misquoted Alan Turing.

Update, 2021-07-13: I made two videos related to DD misquotes:

Video about the Feynman misquote: "Science is what we have learned about how to keep from fooling ourselves.". This video goes into more depth.

Video about this blog post about DD's misquotes. This video is more of a broad overview.

David Deutsch Retrospective Thoughts

This is part of a series of posts explaining the ongoing harassment against me from David Deutsch and his associates and fans.

David Deutsch (DD) was never as good as I thought. But he had some great ideas, particularly re physics (as far as I know) and Critical Rationalism (CR). He read Popper and understood a lot – while others fail to understand much Popper. He also understood Dawkins and connected CR with neo-Darwinism, and he understood stuff about computation and information theory. The four strands in The Fabric of Reality (FoR) are good, valuable, etc., though DD overemphasized them. They are just four strands out of over ten, not the top four. Math, logic, (classical) liberalism, (Austrian) economics, moral knowledge (including from Objectivism, Judaism and Christianity), and Theory of Constraints are examples of other major, important, deep areas of human knowledge. DD was overly narrow when I knew him, and wouldn’t reread Rand or Szasz (he knew stuff about their ideas, but also had forgotten or never known a lot of it), and would never learn Mises or Burke for the first time (he knew some Hayek, who was Mises’ student, but Mises was much better). One of the issues is that DD reads fewer books than people think he does. I had to repeatedly recommend some Feynman books to get him to read those (he’d read some long ago, but never read others), and I was unable to get him to read much else.

Aside about DD’s lack of reading: In 2012, DD blatantly contradicted Szasz. I’d read over a dozen Szasz books recently, and I’d discussed them with Szasz himself. Nevertheless, DD didn’t believe me about what Szasz’s view are, and didn’t want to reread Szasz as I urged him to. But DD was confident enough to challenge me (my italics): “If you quote a statement or short passage of mine in this thread, and a statement or short passage of Szasz's that contradicts it, I promise to re-read the whole book in which Szasz's statement or passage appears.” I provided quotes. One of the issues was that DD was unaware of Szasz’s opposition to the medicalization of everyday life, even though Szasz titled a book about this issue. DD thought it’d be “harmless” to call effective anti-Islamism arguments a “cure” or “treatment for Islamism”. After I gave quotes, DD acknowledged that he “wasn't aware that Szasz totally rejects the use of the term 'treatment' in the way I used it, i.e. to describe what psychiatrists do.”, bought the book on Kindle (so he got it immediately), and said he’d read it. But he never actually read it and followed up. This incident disturbed me because it was a clear example of DD lacking integrity. He made a “promise” then broke it.

FoR and The Beginning of Infinity (BoI) are primarily about CR. They build on CR some and connect CR to other areas. Not many people understood enough Popper to start working out implications of CR, and DD succeeded at that and also learned some other important stuff that he could connect CR to. That’s impressive and was a contribution to human knowledge.

I recently discovered that BoI has lots of misquotes. DD is a worse scholar, with less integrity, than I thought.

DD has other notable ideas outside of physics, too. Taking Children Seriously (TCS) has important insight mixed in, but is also too disorganized and has major errors. DD’s static meme idea is good (I don’t think it’s perfect or complete, but it’s a good lead/start/try). He got a lot right about politics and economics, such as advocating capitalism, but he didn’t contribute much there. DD’s idea about the jump to universality is a good start on something important, as is his criticism of weighing explanations. DD’s anti-weighing ideas are some of the inspiration for my Yes or No Philosophy.

Original thinkers take risks. They may be wrong some. DD’s attacks on age of consent laws were a mistake. His attack on monogamy had some reasonable points but overall I’d say that was a bad idea that needed to be thought through more. DD doesn’t understand or respect tradition and traditional knowledge enough, but he was willing to make bold claims, some of which were good. It’s a lot better to say something important and also three wrong ideas than to say nothing risky or important.

DD was personally irrational about tidiness, scheduling, food, children and more. And he accepted a bunch of irrationalities as unsolvable problems and didn’t try to fix them.

DD’s extremely biased about ageism. He sees some ageism that most people don’t, but he also sees ageism when it isn’t there. For example, DD once argued to me (in 2004) that a news article mentioning metaphorically taking a politician behind the woodshed shows that violence against children is part of the fabric of our culture. DD claimed people wouldn’t say such awful things in general, and are only willing to do it due to ageism. I said people still talk about hanging, which isn’t due to ageism, it’s just because society does use violent words. (There’s a children’s word game named “hangman” which is used in classrooms.) DD was so biased that he responded: “[The word] Hang doesn't have a connotation of baseness and horror.”. He denied the badness of hanging because it isn’t anti-children and he wanted to claim anti-child stuff is much worse. Hanging kills people, which makes it more base and horrific than beating someone behind a woodshed. Also hanging is public violence, while behind a woodshed means privately (second source).

DD’s arrogant and stopped learning much before I met him in 2001. He’s dishonest with others on purpose, including his friends, for a variety of reasons including conflict avoidance and social climbing. He’s really scared of the world and of conflict with people, and he tries to hide problems (contrary to his philosophical theories about problem solving).

He’s a social climber who cares deeply about his reputation. I’m not sure how much he always was. I think maybe he was less concerned about it when he started TCS, and may have been changed by the negative experience of TCS’s failure to catch on and the hateful reactions it got. He may also have gotten more scared after a negative incident with the government around 2003 (but he kept advising other people not to be scared of the government, and some of that advice was horribly unrealistic and irresponsible, and could have gotten people’s children taken away).

DD’s a two-faced person and extremely biased about Lulie Tanett (LT). He put a lot of work into telling me to be friends/colleagues with LT, and telling LT to be friends/colleagues with me, but he also went behind my back and sabotaged our interactions sometimes. He said negative stuff about me to her while hiding what he was doing from me. One time, he put a lot of work into convincing her that I was threatening her when I told her some conditions she’d have to meet to remain a member of a small, private discussion group I owned (the conditions were basically just being an active poster). DD basically told her that learning from me was her best chance fixing her problems and becoming a rational, productive intellectual, so alienating her from me like that was really bad, though he did much worse later.

After leaving my community, he heavily pressured her to drop me entirely, and finally after around five years of pressure she dropped me. Doing that after convincing her I was crucial to her learning – and after she was very attached to me – was really horrible of him. It’s a little like a coercive parent controlling who their kid is allowed to be friends with. But it’s much worse to belatedly take away a friendship from your kid, over 10 years after it started, that you recommended and convinced them was crucial to their career.

DD really messed with LT’s head and her lack of accomplishments and inability to do productive work or learn much philosophy is significantly his fault. It’s also Sarah Fitz-Claridge’s (SFC) fault and TCS’s fault. SFC publicly posted on 2006-03-31 on TCS list that LT is her daughter, though they all seem to be trying to hide it now. Most people don’t realize that when DD promotes LT, that’s basically nepotism. DD has known LT since she was around age 2, and SFC moved her family to live near DD in Oxford when LT was around 7. DD treats LT partially like a daughter. However, he won’t take responsibility for actually trying to treat her in a TCS parenting way because that’d be too much work for him. In general, DD likes to keep things flexible and avoid having clear responsibilities, even with his closest associates. (E.g. he said that he avoids having anything scheduled at a specific time because having something coming up today or tomorrow often prevents him from working.) He mostly avoided explicit obligations with me, too, though he made exceptions like saying he’d write a forward for my book, saying he’d write a TCS book, and, as I discussed above, promising to read a Szasz book.

TCS parenting worked out badly for LT. TCS, SFC and DD did poorly in practice, but they’re dishonest with the public about TCS’s practical results.

SFC’s post saying LT is her daughter was an announcement of an official TCS event at SFC’s home in the UK. The event involved me, SFC and LT giving speeches about TCS, plus Q&A. The post also said LT “will be taking over the management of the TCS web site”, but then SFC violated TCS principles by breaking her word to her own daughter (LT wanted the TCS website, but SFC refused to hand it over while leaving it inactive – it’s been inactive for 15 years now). After the TCS event, SFC told me and LT that she despised the TCS parents who attended, had met them before, and thought they were hopeless and would never make progress on their problems. She hid her negativity while they were present. SFC also broke her word about letting LT and I have the money we charged for the event, and, after the event was over, she decided instead to simply take a share for herself without discussing the matter. She either took half or a third (I don’t remember). It wasn’t a lot of money and didn’t matter much to me, but I was disturbed that she’d break her word and take money away from her child who had very little money. And it’s ironic to screw over your child for money from a TCS seminar which talked about treating children well.

DD met another mother of young children before SFC, but stopped associating with that family because he didn’t think the mother was a good enough parent. Specifically, he found out that the mother had told the kids to be on their best behavior when visiting DD, so he ended things with them. But SFC was an awful parent and DD put up with it. I’m told she routinely closed her office door while her toddlers fought outside. I don’t know why DD got rid of the first mother but then put up with SFC’s bad parenting. (Source: I’ve been told things by people who were part of the TCS community before me and who knew SFC/LT/DD/etc in person.)

SFC also mistreated DD himself, and he put up with that too, though I observed that after he was already highly invested in TCS, SFC, LT and LT’s sibling. When I visited the UK for three weeks, DD gave me a draft chapter of BoI to read and discuss. SFC was jealous that she didn’t get one. She kept bugging him about it repeatedly and trying to pressure him into giving her one (he refused). She was a bad friend who didn’t respect his control over his writing process.

I found out a lot about DD being two-faced with me because LT told me lots of the private stuff DD said to her (without getting his permission or telling him that she shared it). I don’t think she was wrong to do that, btw. DD was like a father to her (actively involved in her life since she was a toddler) and somewhat of a father-figure to me. It’s reasonable and understandable for kids to share information and discuss strategies for dealing with the irrationalities of their parents. On the other hand, I also think LT learned to be a two-faced gossip from DD and SFC, and there’s a major problem there. She sometimes shared info about me and others with people she didn’t know well (she confessed to doing this). Similarly, DD started badmouthing public figures (particularly ones he’d personally interacted with) to me when he hadn’t known me very long yet, and he kept doing it despite me frequently just literally not responding at all to it. Imagine how much mean gossip he’d tell someone who actually encouraged it…

DD wanted a student. He liked me when he gave partial explanations that almost no one could learn from, and I figured stuff out (often more than he meant or knew). That worked well when his conclusions were correct. But I couldn’t usually come up with convincing reasons for DD’s claims when he was wrong. Over time, I learned most of the stuff he was right about and that put more emphasis on the issues where we disagreed, since there was less other stuff left for him to teach me about. DD was never rational about debate and truth-seeking. I’m not sure that he ever changed his mind about anything major due to my arguments, despite thousands of hours of discussions. I did successfully correct him on many smaller things, including in the seven years I commented on and edited drafts of BoI, but he didn’t post mortem those errors to look for larger errors that could be root causes.

Anyway, DD helped me understand a lot of his ideas. Some were great and some were errors. Overall, engaging with him and his ideas was very intellectually beneficial for me. I wouldn’t regret it just because he left me. But I really do wish he’d leave me alone now. Hating me for no clear reason, and having his fans harass me, is really nasty. I didn’t recognize how irrational and dangerous he was. I don’t know major things that I should done have differently with DD, even in hindsight, though.

David Deutsch Books Unendorsement

I thought that even though David Deutsch (DD) and his fans were harassing me, his books were still good. But I hadn’t reread them for years. On review, The Beginning of Infinity contains lots of misquotes. DD’s books are a lot worse than I realized. I was horrified to discover how frequently and severely DD misquotes. I trusted DD’s ability to quote accurately and handle details reliably and correctly, but I was wrong.

Also, DD explains too little in his books. They’re too hard to learn effectively from because he doesn’t give enough depth or detail. I had trouble seeing this in the past because I had many conversations with DD which filled in the gaps for me. But even when DD’s books say something important, he often doesn’t provide enough information for a reasonable, smart person to understand it well.

DD’s books have some good parts mixed in, but, due to the serious flaws, I retract my recommendation of them. I no longer want to actively promote them.

I’m sorry. I should have caught the misquotes earlier. I was capable of finding those errors years ago. I found and wrote about other similar errors.

I was giving DD space after he left the community. I guessed (I think accurately) that he wanted to be left alone by me and I was trying to respect his wishes. I mostly stayed away from him and his work after he left. I thought continuing to recommend his books was safe, but I was wrong about that.

I only started my video series about BoI after I gave up on DD leaving me alone. I caught the Feynman misquote in chapter 1 when I first reread it for the videos. BoI misquotes Feynman:

As the physicist Richard Feynman said, ‘Science is what we have learned about how to keep from fooling ourselves.’

Then, due to the harassment, I was reviewing old information and found a Popper misquote on an old TCS webpage. Someone (“Dec”) saw my post and told me that the same Popper quote was in BoI too. That made two misquotes in BoI, which was a possible pattern. That led to checking more quotes, which led to discovering that there are tons misquotes in BoI.

It seems that no other readers of BoI have noticed the misquoting problem yet (the errata page has factual errors but no misquotes), which I think is important information about the world. Regardless, I should have done better.

Read about the misquotes.

Beginning of Infinity Website Removed in Protest

I took down the website beginningofinfinity.com and replaced it with the below protest message.

This website promoted David Deutsch’s book The Beginning of Infinity (BoI). David was my friend, mentor and colleague. I helped with drafts of BoI for seven years (I wrote over 200 pages of suggestions, comments and edits to help with the book). At David’s request, I made and owned this BoI website and the BoI Google Groups forum.

I’ve taken this site down in protest due to David’s role in harassment against me. I’ve been harassed by his fans and he lied about me. They’ve disrupted my blog, forums, and ability to discuss with other intellectuals online.

I also discovered many misquotes in BoI which, alone, would be enough reason for me to stop actively promoting BoI.

The story in short: David (and his Taking Children Seriously co-founder Sarah) created an online community which I was part of, but then he left after 15 years. Now he has a second fan community, which is harassing the first community. The harassment is primarily targeted at me, presumably because I’m now the leader of the older community. One of the motives some people have communicated is that they see me as David’s enemy.

The harassment has persisted for years, and has included dozens of fake identities (some maintained for months), hundreds of harassing messages from over one hundred IP addresses, stalking me to other websites to disrupt my conversations there, DDoSing, impersonation, threats, spam, plagiarism, libel, fraud and doxxing. Some of that is illegal (I am not a lawyer; I’ve presented evidence; judge for yourself).

David has been unwilling to ask his fans to stop, to discuss the matter privately or publicly, to explain himself, to dispute any of the evidence, to state a grievance he has against me, or to offer any terms for truce. I’d be willing to do conflict resolution through proxies or associates (David’s, mine or both) but he’s been unwilling to do that.

When asked to tell his fans to stop harassing, David not only refused, but turned it around and lied to attack the victim (me) which justified and encouraged additional harassment. His lie is damaging to my reputation and it seems likely that he’s said it to other people privately. Rather than deescalate, he choose to openly join in the harassment himself by smearing me. He hasn’t retracted his lie, nor has he denied circulating it privately so that harassers believed it and were motivated by it. This is despite me posting documentation that he’s lying. (I understand David’s lie to be libel and defamation, but I don’t have the resources to stop it. I am not a lawyer and you can read what he said at the link, along with the actual facts, and judge for yourself.)

I finally gave up and closed the comments on my blog – after 18 years and over 20,000 comments – due to being unable to deal with the harassment there. I’ve also been harassed at Reddit, Less Wrong, Twitter, Facebook, Google Groups, Basecamp, Discord and Slack. They won’t leave me alone.

David hasn’t argued that he isn’t involved or explained why his actions are OK. He hasn’t said which facts or claims he accepts or denies, presented his own account of events, or argued that my account is false. He hasn’t denied gossiping negatively about me, nor said what he’s doing to avoid crossing the line into unacceptable behavior. He hasn’t given an innocent explanation for the links between the harassment and his social circle.

David hasn’t taken steps to distance himself from the problem or to reduce the harm being done. He hasn’t stated that he’s opposed to harassment in general or to any of the harassing actions by his fans against me. He hasn’t blocked the worst harasser on Twitter, and keeps tweeting with him. David won’t do anything to delegitimize the harassment. Many of David’s friends and associates behave similarly or worse. David won’t even pay lip service to saying that I’m not his enemy or that I shouldn’t be harassed.

David also hasn’t disowned the subreddit for The Beginning of Infinity, which was created by the worst harasser. Nor has David disowned a nasty message posted under the name “David Deutsch” (I believe it was impersonation, which is something that ought to concern David). I think some of David’s fans have taken his behavior as a signal that he wants me harassed, and he’s refused to deny wanting me harassed.

I’ve documented the harassment, provided extensive evidence, and explained what’s going on. The response has been a mix of silence and more harassment. David is more powerful and influential than me, and has more support and resources, so there isn’t much I can do besides speak truth to power and hope that reasonable people listen. I’ve tried to put up with things, ignore things for months, privately ask for a peaceful resolution, publicly ask for a peaceful resolution, etc. In the past, David spent thousands of hours discussing with me, but now he’s stonewalling all attempts at deescalation.

I have the right to be left alone, not harassed for years. My rights are being violated, and I think David is the root cause of the problem. David needs to take appropriate steps to reign in his toxic community, and needs to retract his lie about me.

If you’d like to help, please ask David and his community about the problem, criticize them and complain, but don’t harass them in return. Maybe David will stop his bad behavior if people complain. David’s public email address is [email protected] and his Twitter is @DavidDeutschOxf.

For more information, read my articles about the harassment. To contact me, email [email protected].

David Deutsch Harassment Update

I took down the Beginning of Infinity website in protest two months ago, after David Deutsch (DD) and his fans harassed me repeatedly for years. They won't discuss why or stop. What's happened since then?

  • Three CritRats (members of DD’s fan community) harassed me on YouTube.
  • Two DD fans posted hostile comments, aimed at me, on Alan Forrester's blog, after I disabled comments on my own blog.
  • A CritRat is plagiarizing me and won’t respond about the issue (he offers no excuse, defense or explanation). Plagiarism of me by CritRats is a recurring problem due to their toxic community. Many of them seem to actually like my ideas, read my stuff regularly (including CritRats who I used to speak with and also CritRats I've never had a conversation with), and only dislike me because they were told to or were told lies about me. But CritRats can't give me credit for anything without hostile reactions and likely being kicked out of their community, so they are sorta being pressured into plagiarizing.
  • I found out from multiple community members that DD personally contacted them (over 5 years ago) and tried to recruit them to his side and turn them against me. DD did this in writing and I've received documentation.
  • DD still has not retracted his lie about me, nor asked his fans to stop harassing me.

Maybe people feel justified attacking me with sock puppets because DD lies to them that I do that to him. There have been repeated signs that people got this idea from CritRat community gossip, and DD is the community leader and I now know that he has said it to people. I have now seen DD, in writing, gossiping to people to try to turn them against me, mocking me and encouraging hatred, and specifically telling people that some of his critics are my sock puppets (with zero evidence, and with the hyphenated spelling "sock-puppet"). And if DD were correct, as he believed he was, then he would have been doxxing me by outing an anonymous account as me. And what enabled the attempted doxxing? Our friendship. If I were a stranger or a forum poster he only knew impersonally, then DD would not have been able to guess which accounts were mine and convince others that he was probably correct. (BTW the account DD claimed was my "sock-puppet" in multiple emails was an openly anonymous account that didn’t claim to be a unique person who wasn’t already in the discussion, so it couldn't even have been a sock puppet in the usual sense. The posts DD were upset about consisted primarily of quotes from his books to show what he’d actually written, which DD considered an attack. DD didn’t want to, and didn’t, clarify his positions on the matters being discussed, and was upset that anyone would use his book quotes against him to try to tie him to specific viewpoints that could be criticized.)

Since the problem is active today (ongoing harassment, my blog comments still disabled, DD's lie not retracted, no attempt to clean up their toxic community and prevent further harassment, etc.), I’m going to share more information related to DD’s harassment campaign. This time, I’ll provide evidence that DD is a mean person who is capable of mistreating me, since that seems to be something that people doubt who don't know him personally. People may find it implausible that he’d be so cruel to me – his behavior is so bad that some people doubt I could be telling the truth – so hopefully seeing some of his other bad behavior will help persuade people.

I don’t want to take actions like this, and will be happy to stop when DD takes actions to improve this intolerable situation. He should make a reasonable attempt to stop his community from harassing, including asking them to stop and enabling some line of communication so that incidents can be reported and addressed. (In source links below, chats are displayed using Past for iChat.)


2011-05-12: David Deutsch called Sam Harris “gullible as a sheet of paper” and said Harris’ writing about meditation has no meaning (“meaning is there none”). David then went on Harris’s podcast, twice, and acted friendly. Source.

2008-06-20: David Deutsch insulted Richard Dawkins. “Dawkins should write his God stuff under a pseudonym. (And his political stuff on toilet paper and just flush it.)” David based one of four strands in his first book on Dawkins’ work and has had friendly conversations with Dawkins in person. Source.

2010-08-29: David Deutsch praises anyone who “violently” “hates Chomsky. Source.

2009-03-11: David Deutsch says Scott Aaronson is “not a serious thinker. He’s just a mathematician with delusions of competence (and indeed authoritay) in philosophy, politics etc.” Source. And on 2010-04-06, he mocked Aaronson as someone he really wouldn’t want to be Facebook friends with. Source.

2003-04-26: David Deutsch attacked Rafe Champion (a Popper scholar whose work David is currently recommending) as both “insane” and “anti-Semitic”. Then David was friendly to Champion in emails (I saw some of them) for at least the next nine years. Source.

2008-06-25: David Deutsch insulted Thomas Szasz (author of The Myth of Mental Illness) saying he “only knows two things, maybe three.” Deutsch also mocked Szasz’s accent. Previously, Deutsch met Szasz in person, was respectful to his face, and got his copy of Szasz’s book The Second Sin signed by Szasz in 1988 (Deutsch still had the signed book in 2012). Source.

2010-10-01: David Deutsch was involved in meetings to set up a proposed “Future Technology Institute” with other senior members including Nick Bostrom who heads the Future of Humanity Institute. Deutsch mocked the others: “They are scared that AIs may go rogue and fill the world with paper clips. They are more scared of this sort of accident than of bad governments using AI as a weapon.” He also accused them of being pandering social-climbers (and confessed to being that himself): “Mostly we were all trying to impress the sponsor with our cleverness and depth. So nothing has actually happened yet.” Source.

2008-06-20: David Deutsch says Daniel Dennett’s ideas “are about as good as a rottweiler’s”. This is extra insulting because David believes dogs aren’t intelligent at all and don’t have ideas. He believes the animal rights movement is an error because animals are literally 100% incapable of thinking, having any emotion or suffering. In my experience, David often ridicules animals and uses them in jokes and negative comments. Source.

If these quotes have convinced you that DD could be doing something wrong, you can read about the harassment campaign. You can also complain to him. DD's public email address is [email protected] and his Twitter is @DavidDeutschOxf. Perhaps the best way to help is by sharing this information with more people.
