Is man the rational animal, or are there a lot of irrationalities in our everyday decisions, and has your belief altered since you began reading LessWrong

Man is the most rational animal, and there are a lot of irrationalities in our everyday decisions. I don't remember explicitly thinking about it, but I would guess that I'd have thought it obvious before reading LessWrong. I know I didn't have trouble understanding the reason for the title of this blog.

Did you previously have any beliefs on QM interpretations, and have they been affected by reading LW

I was previously agnostic. Seeing Eliezer mention that MWI was true shifted my beliefs significantly towards that. Learning enough QM to understand why shifted me the rest of the way.

Has reading LessWrong affected your levels of productivity in any way, and if so, how?

I don't know.
