Instead of thinking things through, we rationalize after-the-fact.

The same could be said for marriage: people do it because they've been programmed to think it's the "right" thing to do, then rationalize it by calling those who don't want to get married "losers who are afraid of commitment." It seems the evidence would show that thinking things through as leading to not getting married, as opposed to the other way 'round.
