Low vs. High Decouplers

I just came across a study showing that people in the hard sciences are "high decouplers"--meaning able to separate unrelated issues from each other--while artistic types and those in the humanities are low decouplers. This could explain why humanists are far more ideological and dogmatic in their ideology than are hard scientists. An ideology is a collection of unrelated positions (e.g., high taxes, abortion rights, pacifism). High decouplers will be able to see the unrelated nature of these issues and approach them one by one. Low decouplers will lack that ability and adopt them as a package.
