Thinking About Social Norms

This article argues that it is a waste of time seeking to treat populists as examples of homo economicus when seeking to persuade them that the conspiracy theories to which they subscribe are big lies.

Such an approach requires a willingness to entertain both proximate and ultimate explanations of human behaviour simultaneously.
