Humans are rational, just not in the 'mathematically rational' sense. I.e., not just using statistics and probabilities to make decisions. As long as decision-making involves a process (even if it's unconscious) of trade-offs to optimize total utility, it's still rational (well one can debate if should be called 'rational' or have some qualifier attached to it, but then it becomes a definition question, a rather boring one).
