William Reville posed the question in the Irish Times:
He opines:
Every social scientist I ever met was liberal-left. This uniformity always struck me as very odd. I accidentally came across a new, rigorous academic analysis of this question in the journal Behavioral and Brain Sciences. The authors are worried by recent problems in social psychology research, including fraud and problems with replicating results
Further:
Psychology has robustly demonstrated the value of diversity of viewpoints for improving creativity, discovery and problem-solving. The authors conclude that lack of political diversity undermines much social-psychological science by embedding liberal values into the research questions and methods, by steering researchers away from politically unpalatable research topics and results, and encouraging conclusions to be drawn that mischaracterise liberals and conservatives. Of course, homogeneously conservative social sciences would face the same problem as homogeneously left-liberal social sciences.

I expect young people to be liberal and a lot of social science is young, but I have suspected that there is more than a little group think involved for some time in social science with the potential for driving disastrous social policy.
What do people think?
