SOCIAL SCIENCE DISCOVERS EXPERIENCE-LOVING, HARD-THINKING LIBERTARIANS

Yesterday I referenced Michael Shermer and his new book. Shermer is part of the discussion over at CATO and this conversation is on point:

I also recommend the work of Dan Klein - this paper is both representative and informative. http://www.criticalreview.com/2004/pdfs/klein_stern.

A telling anecdote was reported in the New York Times earlier this year when University of Virginia researcher Jonathan Haidt asked participants in the annual meeting of the Society for Personality and Social Psychology how many in the audience considered themselves to be politically liberal. As the Times reported:

A sea of hands appeared, and Dr. Haidt estimated that liberals made up 80 percent of the 1,000 psychologists in the ballroom. When he asked for centrists and libertarians, he spotted fewer than three dozen hands. And then, when he asked for conservatives, he counted a grand total of three.

“This is a statistically impossible lack of diversity,” Dr. Haidt concluded, noting polls showing that 40 percent of Americans are conservative and 20 percent are liberal. In his speech and in an interview, Dr. Haidt argued that social psychologists are a “tribal-moral community” united by “sacred values” that hinder research and damage their credibility—and blind them to the hostile climate they’ve created for non-liberals.

The process of science is supposed to help humanity overcome our innate tendencies toward confirmation bias—a point strongly made in Shermer’s new book. Science is necessary because confirmation bias is everywhere. Research by Dan Kahan and colleagues at the Yale Cultural Cognition Project[2] has shown time and again that when confronted with policy issues involving tradeoffs involving technological benefits and risks, it turns out that those who identify as liberals (egalitarians and communitarians) in particular fear change and—to quote Jost—“reject out of hand scientific findings that might be experienced as disagreeable.”

For example, a 2009 poll[3] by the Pew Center for the People and the Press reported that 70 percent of scientists favored building additional nuclear power plants. Sixty-two percent of Republicans also favored this, but only 45 percent of Democrats did. A more recent Pew poll [4] (without reference to scientific opinion) done after the nuclear disaster in Japan found that 49 percent Republicans still favored increased use of nuclear power, whereas only 31 percent of Democrats did.
