Mark Friedenbach's post Leaving LessWrong for a more rational life makes a few criticisms of the way LW approaches rationality. It's not focused enough on empiricism. While he grants that there's lip service payed to empiricism Mark argues that LW isn't empiric enough.
Part of empiricism is learning from errors. How do you deal with learning from your own errors? What was the last substantial errors you made that made you learn and think differently about the issue in question?
Do you have a framework for thinking about the issue of learning through errors? Do you have additional questions regarding the issue of learning through errors that are worth exploring?
So you can't learn from mistakes if you don't discuss the issue at hand with other people?
I consider errors identified as the main (perhaps only) way to be less wrong. Popper emphasized the benefits of making mistakes in public even further.
