This is a really great talk, and I am amused because she opens the talk with an anecdote about a road trip from Providence, RI to Portland, OR. http://www.ted.com/talks/kathryn_schulz_on_being_wrong.html
Oh oh oh she has a blog! http://www.slate.com/blogs/thewrongstuff.html
This one is related and also wonderful: http://www.ted.com/talks/michael_shermer_the_pattern_behind_self_deception.html
Haven't seen the videos, but love the blog and will have to read more.
