Michael, please don't be so quick to dismiss this as not having an evolutionary advantage.

It would serve as a mechanism to make those with psychological problems into less acceptable candidates for mating. By using social structures to choose mates, you would be selecting those most suitable for life in society.

You're correct in that it probably has no impact on running away from a predator, but predation is not the only force driving the adaptation of species, though it is a major one.
