[quote=zk]Ok, rereading it, I guess you mean that if the behavior is irrational, then the explanation of that behavior must also be irrational.

But that doesn’t make any sense at all. Of course there are many rational explanations for various irrational behaviors.

Since there are many, how about just 3 (for the case of mob mentality as it relates to so-called Black Friday)?
