Do you have the link to the actual study and data for "The Truth Wears Off"? I have read a few summary article sprinkled around the web but it has always come off as pseudoscience to me. This is a hug claim and I have seen no evidence to back it up.
It's a popular article, not a study. It references several scientists; Jonathan Schooler on the "decline" of his results on verbal overshadowing, Michael Jennions, and so on. (I was able to find the full text by combining the article title and the term "PDF" in one Google query.)
Seth Roberts has some comments.
This blog which I've just stumbled across and haven't read yet has more commentary.
Are there any areas of study that you feel are underrepresented here, and would be interesting and useful to lesswrongers?
I feel some topics are getting old (Omega, drama about moderation policy, a newcomer telling us our lack of admiration for his ideas is proof of groupthink, Friendly AI, Cryonics, Epistemic vs. Instrumental Rationality, lamenting how we're a bunch of self-centered nerds, etc. ...), and with a bit of luck, we might have some lurkers that are knowledgeable about interesting areas, and didn't think they could contribute.
Please stick to one topic per comment, so that highly-upvoted topics stand out more clearly.
