Yes, but what is the purpose of compartmentalizing beliefs into bin A and bin B where the things in bin A are true and the things in bin B are false?
There is a deep deep bias on LW of thinking that truth is the only aspect of belief that has value. But there's tons of other aspects of beliefs that have value - how happy they make, how much social acceptance they get you, how useful they are in achieving your goals - an many times these things are at cross purposes with the truth.
The beauty of compartmentalization is that you may be able to get the benefits of the truth while ALSO getting these other benefits.
This is true, but one could use some other terminology rather than abuse the word "truth". Aumann is giving ammunition to every continental philosopher who argues that truth is relative or arbitrary, then tries to bring that into public policy.
I lose respect for Aumann for saying this. I have respect for Anders Sandberg, who in the past practiced some neo-paganism, with religious trappings, but when asked about it would explain (IIRC) that he was tricking his mind into behaving.
Just came across this interview with Robert Aumann. On pgs. 20-27 he describes why and how he believes in Orthodox Judaism. I don't really understand what he's saying. Key quote (I think):
Anybody have a clue what he means by all this? Do you think this is a valid way of looking at the world and/or religion? If not, how confident are you in your assertion? If you are very confident, on what basis do you think you have greatly out-thought Robert Aumann?
Please read the source (all 7 pages I referenced, rather than just the above quote), and think about it carefully before you answer. Robert Aumann is an absolutely brilliant man, a confirmed Bayesian, author of Aumann's Agreement Theorem, Nobel Prize winner, and founder / head of Hebrew University's Center for the Study of Rationality. Please don't strawman his arguments or simply dismiss them!
