@Gargron choosing is thinking in the first place. And thinking is one of most difficult task, as it requires quite a lot of energy. To conserve that energy many people replace thinking with believing as it makes shortcuts when one is deciding, thus saving energy. Now it is a matter of what you trust. Or what's cool/trendy/etc. In the beginning I was also surprised by short-thinking of majority of the people I know, but now I'm surprised why nobody teached them to think in the first place....
