1) Kahneman had a chapter in his book about social priming, and endorsed the subfield, which was totally decimated by the reproduction crisis. But Kahneman himself didn't research social priming, and I don't think any of his research with Tversky has been challenged by the reproduction crisis. I think it's unfair to say he was "right in the middle" of it, unless I'm missing something.

2) What's wrong with Katsuyama? If you mean IEX was a dumb idea and HFT is good for markets overall then I agree with that. I think that just means Katsuyama is wrong and self-serving, not problematic.

Right, so my meaning here is subtle: that it makes a problematic subject for a book intended to have a clear protagonist, not that Katsuyama is a bad person (I don't know anything about them beyond the book).

Gotcha. I agree that the main premise of Flash Boys was wrong, HFT is unambiguously better for retail traders than the market makers that preceded it.
