This, I think, can also explain the “gushing fanboy” phenomena where otherwise rational people refuse to admit that their idol (be the idol an actor/singer/writer/director, etc.) might just have been subpar in their latest effort.
So basically, they’ve proved, (with brain scanning no less,) that people are capable of ‘switching off’ their critical thought processes because of an emotional reaction.
Is anyone else thinking… DUH? In other news, the sky is blue during the day if there aren’t any clouds.
