Habits that are actually signs you're smarter than you think

Intelligent people use more curse words

You always hear, that people who swear have a "limited vocabulary". But if you think about it, those who don't use any swear words are the ones who limit their own vocabulary, because they intentionally use fewer words than others. In fact, there is a study deconstructing that myth about curse words. The result showed that people who could name the most swear words within a minute also tend to score higher on an IQ test. The study concludes that a rich vocabulary of swear words is a sign of rhetorical strength rather than the attempt to hide verbal deficits.
