I asked him if he'd come on to be interviewed as part of it, and he said he'd be interested. I believe he is not opposed to me doing the episode.

Thanks for your comment. Some thoughts:

"But a lot of your pro-DAE evidence seems to me to fail this test. E.g. ok, he lied to the customers and to the Congress; why is this substantial evidence of DAE in particular?"

Because E is evidence in favor of a hypothesis H if:

P(E given H is true) > P(E given H is false)

And the strength of the evidence is determined by the ratio:

bayes factor = P(E given H is true)/P(E given H is false)

In my view there isn't really any other reasonable mathematical definition of evidence other than the bayes factor (or transformations of the bayes factor).

Applied to this specific case:

Probabilityiity(Lying to congress given DAE) > Probability(Lying to congress given not DAE)

And the reason that inequality is true is because people with DAE are more likely to lie than people without DAE (all else equal). 

"Everything under this seems to fail the rain test, at least; very many people have this willingness [to lie and deceive others] most of them don't have DAE (simply based on the prevalence you mention). Is this particular "style" of dishonesty characteristic of DAE?"

The question of whether E is evidence for H is not the same as the question "Is H true most of the time when E?" That's just a different question, and in my view, not the correct question to ask when evaluating evidence. The question to ask to evaluate evidence is whether the evidence is more likely if the hypothesis is true than if it's not true.

And yes, lying is indeed characteristic of DAE. 

I’m glad to see that Nonlinear’s evidence is now public, since Ben’s post did not seem to be a thorough investigation. As I said to Ben before he posted his original post, I knew of evidence that strongly contradicted his post, and I encouraged him to temporarily pause the release of his post so he could review the evidence carefully, but he would not delay.

At the top it says it’s a link post and links to the full post, I thought that would make it clear that it’s a link post not a full post.

It’s difficult to keep three versions in sync as I fix typos and correct mistakes, which is why I prefer to not have three separate full versions.

The reason I talk about DAE and not NPD is because DAE and NPD are different conditions, and while I took seriously while investigating this the possibility that NPD was the cause, I didn’t find enough evidence for that explanation, whereas I found a lot of evidence for DAE. If you think I’m wrong, and see significant evidence for NPD I’d be interested to see that evidence.

Not to say that DAE and NPD have nothing to do with each other, but they aren’t the same.

I would never say to someone who was abused by someone with NPD that they are merely experiencing the result of DAE.

To clarify, DAE refers to two very specific things: a person lacking the emotion of guilt, and/or a person lacking the experience of empathy.

NPD in DSM 5, as I understand it, involves: “the presence of at least 5 of the following 9 criteria: A grandiose sense of self-importance A preoccupation with fantasies of unlimited success, power, brilliance, beauty, or ideal love A belief that he or she is special and unique and can only be understood by, or should associate with, other special or high-status people or institutions A need for excessive admiration A sense of entitlement Interpersonally exploitive behavior A lack of empathy Envy of others or a belief that others are envious of him or her A demonstration of arrogant and haughty behaviors or attitudes”

So a lack of empathy (from DAE) is one potential feature or NPD out of 9. Lack of guilt is not on the list at all.

Thanks for letting me know

There were clear ways in which he was really bad at things, but also, clear ways that he was really good at some things.  The FTX exchange is not something easy to build, and it's much harder still to make it into a successful exchange like he did. Seems pretty clear he was really skilled at some things, despite his big weaknesses. But I don't think it can be dismissed as just that he was bad at stuff.  Also, him being bad at stuff doesn't explain highly unethical actions that he appears to have taken.

I do go into that - see the full version on my blog.

It's more specific than sociopathy.  Also, terms like sociopath/psychopath are problematic because people have a lot of associations with those terms, not all of them accurate, and so I thought it would be better to be more precise about what I mean and also to avoid terms that people have connations around.

You're using a different word "utility" than I am here. There are at least three definitions of that word. I'm using the one from hedonic utilitarianism (since that's what most EAs identify as), not the one from decision theory (e..g., "expected utility maximization" as a decision theory), and not the one from economics (rational agents maximizing "utility").
