No.
There are many pages in the sequences devoted to addressing mistakes made by individuals who identify as rational, who associate themselves with the traditions of modern science, and showing how to do better (not just arguments for a procedure that alleges to be more epistemically sound but how it produces better results in the real world.)
In devoting ourselves to the procedures that produce the best tangible results, we have found no reason to take a particular interest in producing criticisms of Popper. If Critical Rationalism distinguished itself as an epistemology that produced exceptional real world results, then matters would be different.
Hmm...I had something else written here, but had a thought causing me to be less certain of what I wrote. I do think Popper should be criticized by someone on this site, to point out what is wrong with his epistemology.
In several places in the sequences, Eliezer writes condescendingly about "Traditional Rationality". The impression given is that Traditional Rationality was OK in its day, but that today we have better varieties of rationality available.
That is fine, except that it is unclear to me just what the traditional kind of rationality included, and it is also unclear just what it failed to include. In one essay, Eliezer seems to be saying that Traditional Rationality was too concerned with process, whereas it should have been concerned with winning. In other passages, it seems that the missing ingredient in the traditional version was Bayesianism (a la Jaynes). Or sometimes, the missing ingredient seems to be an understanding of biases (a la Kahneman and Tversky).
In this essay, Eliezer laments that being a traditional rationalist was not enough to keep him from devising a Mysterious Answer to a mysterious question. That puzzles me because I would have thought that traditional ideas from Peirce, Popper, and Korzybski would have been sufficient to avoid that error. So apparently I fail to understand either what a Mysterious Answer is or just how weak the traditional form of rationality actually is.
Can anyone help to clarify this? By "Traditional Rationality", does Eliezer mean to designate a particular collection of ideas, or does he use it more loosely to indicate any thinking that is not quite up to his level?
