What Was I Thinking?: Books: The New Yorker

What Was I Thinking?: Books: The New Yorker:
"Rational calculators are supposed to consider their options, then pick the one that maximizes the benefit to them. Yet actual economic life, as opposed to the theoretical version, is full of miscalculations, from the gallon jar of mayonnaise purchased at spectacular savings to the billions of dollars Americans will spend this year to service their credit-card debt. The real mystery, it could be argued, isn’t why we make so many poor economic choices but why we persist in accepting economic theory."

exactly. it is hogwash. people are no more rational actors than pigs, maybe less so.
