[Note: This is one of my long comments at another site that I thought I would post here.]
I think our economic lives profoundly influence how we think about broader issues. The degree to which any individual can disagree with one’s superiors and peers without suffering harm to one’s career varies significantly from field to field. In turn, the degree to which mere human opinion plays a role in an individual’s success within a field determines how conformist to common opinion within a field an individual must be to succeed.
