(BISMILLAH) (Salam) http://www.sciencedirect.com/science/article/pii/0022103183900343 I think a better title would be "Cruel but brilliant" as it emphasises on the cruelty and negativity of these guys. Basically, this lady found some very interesting results in a study she did on book reviews where she found that those who had negative and harsher reviews were often perceived as being more intelligent and as having greater expertise than those who simply went along and gave a nod. A quote from another guy: "Being negative makes you feel smarter. The guy who says 'I agree' never seems as smart as the guy who says, 'I disagree.'"
