I am confused. This Washington Post article appears to describe a preliminary study which suggests that politics is less of a mindkiller if you ask people to bet money on their beliefs.

And I am confused because what appear to be my attempts to find the paper resulted in two papers with entirely different abstracts. And papers. Example:

Abstract 1:

"Our conclusion is that the apparent gulf in factual beliefs between members of different parties may be more illusory than real."

Abstract 2:

"Partisan gaps in correct responding are reduced only moderately when incentives are offered, which constitutes some of the strongest evidence to date that such patterns reflect sincere differences in factual beliefs."

I realize the dates on the papers are different, but the shifts seem very dramatic. Thoughts?
