People make emotional decisions or impulsive decisions all the do da day, too. Not every decision is a rational choice.

There is much psychological evidence which suggests that people are totally full of lies when it comes to explaining their decisions, anyway. There is every reason to believe that our decisions are made many seconds before we become consciously aware of them, and we do a few little things to trick ourselves into thinking the decision is evolving in our minds, when really, we're stalling for time to come up with rational, word-based excuses to perform what we were gonna do anyway.
