It's a bit more complicated, but still basically true: a group is not very well modeled as an individual. Heck, I'm not sure individual humans have sufficient consistency over time to be well-modeled as an individual. I suspect that (Arrow's Theorem)[https://en.wikipedia.org/wiki/Arrow%27s_impossibility_theorem] applies to subpersonal thinking modules as well as it does whole people.

A single entity which can believe and act simultaneously in contradictory ways is not really a single entity, is it?
