Is anybody really surprised by this research? I doubt it. Humans love to form exclusive groups. A suit is nearly non-functional and mostly symbolic: I have a job where I am "important" (and I make money). A uniform on a police officer or a doctor or a firefighter? It helps people to distinguish them from the rest of the crowd. A suit on the other hand is a generic line drawn in the sand between people, I feel.
