In the funniest clip, the group changed facing, took off their hats, then put their hats back on, and the subject did the same. It was uncanny. With all of the subjects, there was an initial moment of confusion, a squinting of the eyebrow, but they all followed the lead.
This was all by way of supporting our study of groups and culture and conformity. It was interesting to me, for with my background, I've always been the subject, looking around me, trying to determine the correct and appropriate behavior.
