@JLNobody,
Those things that results from repeated natural occurrences can be predicted, but universal human behavior cannot be predicted. Some group behavior can be predicted to a certain degree, but they are limited - as you say will always be statistical in nature.
Experiments at Stanford and Yale have shown that "normal" college students with above average intelligence can be instructed to torture others under certain circumstances. That cultures like in Japan and Germany during the last century have tortured and exterminated people are probably based on the same human norms of group behavior. We have seen during the recent elections that it didn't matter what the primary candidate for the republicans said, lied, and flip-flopped, but still got the majority votes from his party.
I believe they are of the same human phenomenon of group behavior regardless of the potential results from such a choice.
