Very interesting post from "The Last Rationalist" discussing how the rationalist community seems to have been slow to update on comparative impracticality of formal Bayes and on the replication crisis in psychology.
I don't fully agree with this post - for instance, my impression is that there is in fact a replication crisis in medicine, which the author seems unaware of or understates - but I think the key points provide useful food for thought.
(Note: this is my opinion as a private individual, not an official opinion as a CFAR instructor or as a member of any other organization.)
Well, for one thing, most of the community has not read even most, much less all, of the Sequences. (Linked data is from 2016. Do you think this has changed much in two years? What percentage of currently active Less Wrong posters/commenters do you think have read the entirety of the Sequences, for example?)
It’s an interesting example. “Bayes” appears nowhere in the linked post, I notice. (Several times in the comments—and ever there, never, as far as I can tell, in the context of linking the double crux technique to any Bayesian structure or methods.)
Slightly?!
I… beg to differ. (Which is not by any means to say that there can be no Bayesian treatment of double crux. I entirely take your word for its existence! Unquestionably, you have the expertise, here. But obvious?? No sir, not in the slightest.)
All of this is not to nitpick needlessly, but to point out that to a somewhat-outside observer, it certainly seems like Bayesianism has been quietly abandoned. If that impression is mistaken; if it is the case that actually, everything that CFAR does is based on the most unimpeachably Bayesian of foundations, and in fact constitutes the natural and optimal perfection of Eliezer’s correct, but unpolished, Bayesian approach; well… certainly you must forgive anyone who fails to come by that conclusion unaided.
I expect this is roughly the same. The thing that I don't know is how much of the material in the Sequences is 'in the groundwater', where someone who hangs around a bunch of people who have read the Sequences picks up what they need to know. For example, I predict a similar survey done of members of the church I grew up in would find similar percentages had read similar fractions of the Bible (here's one of Americans as a whole), but it would be confused to think that because they hadn&#...
