A lot of smart people endorse some version of this story. And yes, research surveys show that conservatives do express a much stronger affinity for obedience, authority and in-group loyalty than do liberals.
But there’s a question those surveys can’t answer: How does what people say translate into what people actually do? Jonathan Haidt, one of my favorite social scientists, studies morality by presenting people with scenarios and asking whether what happened was wrong. Conservatives and liberals give strikingly different answers, with extreme liberals claiming to place virtually no value at all on things like group loyalty or sexual purity.
One of Haidt’s most memorable questions involves a man who has sex with a frozen chicken, then cooks the chicken and eats it for dinner. Is this wrong? he asks. Philosophy-class enlightenment values pretty much give one answer: No one was harmed, so it can’t be wrong. And yet: I’m willing to bet that most of the folks who say that it’s A-OK would still be weirded out if they found out this is what their spouse had prepared for a special anniversary feast. Or that this is how a co-worker spends every Monday night.
