David Deutsch’s Irrationality

This is part of a series of posts explaining the ongoing harassment against me from David Deutsch and his associates and fans. To provide background information, I’m sharing some of the most negative things DD ever said to me, which I think reveal some irrationality on his part and reveal some ways that he doesn’t follow his own philosophy principles.


This is an email David Deutsch (DD) sent me on 2011-09-30 (the nested quotes, displayed indented with a black line to the left, were written by me):

you've shown disinterest in explaining these topics for months if not years. e.g. WRT the tcs archives. and lately (several years) have not in general pursued conversations to a conclusion (like deduction, hard to vary, qualia, value of mises, gold standard, burke, tcs archives). so i'd be concerned about the short term strategy lasting a long time.

In regard to hard-to-vary and qualia, the discussions have paused because we have not managed to crystallise a clear statement of what the disagreement is. Both disagreements are rooted in subtle and interesting differences in world view, such that whenever we have gone into details we find agreement, yet stepping back to the overall issue we find strong disagreement. This is a commonplace occurrence among philosophically-minded people. Philosophy is hard. Making progress would require further discoveries, which there is no guarantee of making. I expect there are important things in there to be discovered (by both of us) but it is a fatal mistake to allow an unsolved problem to become a black hole absorbing all one's time and attention, paralysing progress on other problems. This is what you are blaming me for not doing.

The other issues have stalled for a less benign reason. It is that you have developed a repertoire of argumentative tactics which, when applied (you do not always apply them), effectively prevent you from being persuaded of anything. With each particular item on which this has happened (including deduction, Mises, gold standard), I have stopped when I have run out of ideas for how to present the relevant idea to you in a way that gets round the tactics. Just tactics. Nothing to do with content, and I say this independently of whether I'm right or wrong on the issues. These are all issues on which neither of us has any axe to grind anyway.

Currently you are insisting on a reinterpretation of (what seems to me) the plain meaning of a Godwin passage, in order to deny that Godwin expected that in future people would give away most of their wealth. This is a debate that I haven't yet given up on, but the next step, if I pursue it, will require me to explain how you're misinterpreting the word 'if', and I can already think of half a dozen ways you will find to avoid the implication, and I'm guessing you'll succeed in constructing an effective baffle, so I'll have been wasting my time.

And now, in addition to the above-mentioned patterns of argument, your tactics have escalated to include accusing me of fabricating quotes, and having a variety of other personal failings on account of not dropping, and in the TCS-archive case sacrificing, everything else in order to solve things for you.

please advise.

I can't advise on that because I don't know the answer. As for the other things you asked about, I have some ideas about what you should do in order to achieve success and happiness, but it's rather pointless to address those while you consider yourself to have grievances.

i disagree.

This is a commonplace occurrence among philosophically-minded people. Philosophy is hard. Making progress would require further discoveries, which there is no guarantee of making.

i don't think this is it. i will explain why if you want.

I expect there are important things in there to be discovered (by both of us) but it is a fatal mistake to allow an unsolved problem to become a black hole absorbing all one's time and attention, paralysing progress on other problems. This is what you are blaming me for not doing.

i do not think i am blaming you.

it's not even clear to me what you think was blaming, or why. i made some factually oriented statements which, based on your reply (including below), i think you agree with. i said you had shown disinterest and you gave two reasons for disinterest.

The other issues have stalled for a less benign reason. It is that you have developed a repertoire of argumentative tactics which, when applied (you do not always apply them), effectively prevent you from being persuaded of anything. With each particular item on which this has happened (including deduction, Mises, gold standard), I have stopped when I have run out of ideas for how to present the relevant idea to you in a way that gets round the tactics. Just tactics. Nothing to do with content, and I say this independently of whether I'm right or wrong on the issues. These are all issues on which neither of us has any axe to grind anyway.

so, you have adopted a negative meta/psychological view of me, and that is why you dropped those topics without explanation.

thank you for clarifying that.

but what can we do about it?

i think your description (reminiscent of claims made by kolya, about you as well as me) is false. would you like to hear why?

you think it's true. would you like to persuade me of it?

if neither, then what do you think should happen?

Currently you are insisting on a reinterpretation of (what seems to me) the plain meaning of a Godwin passage, in order to deny that Godwin expected that in future people would give away most of their wealth.

changing a key word of your claim (share -> give away) seems like a mistake to me.

This is a debate that I haven't yet given up on, but the next step, if I pursue it, will require me to explain how you're misinterpreting the word 'if', and I can already think of half a dozen ways you will find to avoid the implication, and I'm guessing you'll succeed in constructing an effective baffle, so I'll have been wasting my time.

so, it's the meta/psychological view governing your interaction again.

i don't see why you would debate the "if" part. i said that if one reads on then he finds that the "if" clause is godwin's view, and i accepted it as his view. so, all you could accomplish is to convince me the shorter quote is compelling in isolation. doing so would not have any direct relevance to the discussion.

I said that equalization can be achieved in more than one way, not necessarily by sharing. Why doesn't your intended reply focus on this main point i made?

And now, in addition to the above-mentioned patterns of argument, your tactics have escalated to include accusing me of fabricating quotes,

I did not make that accusation.

this came up previously (w/ your wording "made stuff up"). i explained that you had misinterpreted my meaning. you didn't ask for clarification or debate anything, but now you have repeated this claim as before, seemingly disregarding my reply. why?

and having a variety of other personal failings on account of not dropping, and in the TCS-archive case sacrificing, everything else in order to solve things for you.

i don't understand your seeming strategy here of interpreting criticism -- offered in confusion more than anything else -- as unpleasant accusations.

please advise.

I can't advise on that because I don't know the answer. As for the other things you asked about, I have some ideas about what you should do in order to achieve success and happiness, but it's rather pointless to address those while you consider yourself to have grievances.

what grievances? i do not have grievances.

I think my response email covers a lot of the issues well. I’ll comment further on something I think is particularly important.

This was the end of the conversation; DD didn’t reply to my email. His choice not to reply conflicts with his philosophy that says problems are soluble and advocates common preference finding. For context, keep in mind that we had been friends for ten years and that DD has written thousands of emails to me. The issue wasn’t the time it’d take to write a reply. The issue was that DD was in the process of ending our friendship and his email above gives some info about how and why he did that.

DD was unwilling to discuss any approaches to problem solving regarding the negative meta/psychological view of me that he’d formed. Further, he’d never given me an example. He’d apparently formed negative, undiscussed opinions, for years, and hidden that from me. He disliked some things I said, regarded them as irrational tactics, but never told me even one, so I had no way to stop doing the things he disliked, change my mind or improve. Nor was there any way to correct him if he were mistaken. I still, today, don’t know which things I said that he thinks were irrational tactics, let alone any arguments explaining how my statements were irrational tactics. I’d understand more if he stopped discussing when he though someone was being irrational, but he kept having lots of discussions with me for years while hiding relevant information from me.

If your approach to debate is to decide that the other person is irrational and give up on debate – and to refuse to discuss what the other person did wrong with any examples or arguments – then you are irrational and you are closed to debate. (This is an idea DD taught me, and which he’s repeatedly advocated in writing.)

DD wasn’t taking his fallibility seriously. In his email, he said that he might be mistaken about the object level disagreements, but didn’t acknowledge that he could be mistaken about his meta claims (that I’m irrational and that some of my statements were irrational tactics). DD doesn’t seem to view meta claims as ideas he has which may be false. He treats meta ideas as a special category that shouldn’t be discussed, and that viewpoint prevents error correction of his meta ideas. (DD repeatedly, and in writing, advocated not having meta discussion. That is an idea he said, not my speculation.)

So DD forms off-topic, meta, psychological views of people (his dislike for meta discussion doesn’t prevent him from thinking it and attaching importance to those thoughts). Then he refuses to explain or discuss them, but still assumes they’re true and acts on them. He won’t have meta discussion (sometimes). But he will have meta ideas and let them control and ruin the object level discussion, and then just give up on the object level discussion with no attempt at problem solving because he doesn’t want to critically discuss his unargued beliefs about other people being irrational, having bad psychology, etc. This is a way of destroying the means of correcting errors, not a way of making unbounded progress by truth-seeking.

There were plenty of other times that DD did engage in meta discussion with me. He isn’t consistent about it and never explained a delineation between good or acceptable meta and bad meta. Trying to avoid meta discussions was a recurring theme with DD and also an (inconsistent) moderation policy on TCS list, but he never acknowledged that he wasn’t really against all meta discussion. If he’d acknowledged that, he’d have had to make some statement about which meta discussion he had a problem with and why that sub-category is different and bad, but he didn’t have a good answer to that (I brought it up several times).

This particular comment from DD’s email is particularly notable:

I have stopped when I have run out of ideas for how to present the relevant idea to you in a way that gets round the tactics

Not only did DD never say that he thought any particular statement was a tactic or point out anything wrong with it, he also stopped discussing when he ran out of ideas for how to persuade me. He viewed discussion in terms of coming up with ways to change my mind. But he didn’t take seriously that I might be right about some of the topics. He dropped topics until he had ideas for new arguments, but wasn’t open to listening to my arguments. He didn’t come up with ideas for how to be persuaded and continue discussions when he had some of those. He approached discussion in a one-sided way that didn’t leave scope for him to learn. At least that’s according to his own statement – though actually in practice he sometimes did better than that. He did sometimes listen to me rationally, learn things from me, accept my arguments and change his mind, etc.

You may wish to forgive DD for assuming he’s right because he’s way smarter than most people. That attitude contradicts his philosophy and there’s another problem with it. He had thousands of hours of discussions with me and told me that he respected my intelligence and considered me one of the smartest people he’d ever talked with. He hid his condescending, one-sided, biased approach to discussion from me for ten years of discussions (or maybe he was better in earlier discussions and changed at some point without telling me – I don’t know). He communicated to me that he was taking me seriously. He asked for, and got, huge amounts of my time. That context is nothing like having a short chat with a fan that he doesn’t know. Assuming you’re right briefly with a low social status stranger is problematic, especially given DD’s fallibilist philosophy, but at least that would be conventional arrogance. DD’s condescension to someone after being close intellectual associates for a decade, and very strongly praising their thinking, learning and rationality is worse than that. It indicates that DD assumes he’s right when dealing with everyone – he’s just a poor fallibilist. Or maybe he just assumes he’s right when an issue comes up that he’s biased or emotional about, and it isn’t about the other person or what they say.

In conclusion, DD is irrational and doesn’t live up to the philosophy he advocates. He was dishonest with me for a long time, and the stuff he was hiding built up to major problems which were finally, belatedly revealed in a few harsh incidents like the email above, and then he stopped talking with me. He didn't want to solve problems as we went along and communicate openly about them, nor solve them later either, and he misled me about that for a decade. All this helps explain how his bad and irrational behavior regarding the harassment campaign could be possible.

I added a few more sentences to the final paragraph.
