Study: People who believe in astrology are more narcissistic, less intelligent

While I agree that astrology is bushtit and someone must be stupid to believe it, this study is based in an online poll. From the article:

> Data was collected for 264 participants through an anonymous online survey shared on social media.

I try to write an angry comment every time a "study" based in an online poll with random self selected participants reach an insane conclusion that I think it's false. The problem is that I feel I have the moral obligation to post the same kind of angry comment when the conclusion of the study is something I agree.
