You don't have to be a Mensa member to appear smart. All you need is a smile.

There's a study out that says if you want to give off the impression that you're really intelligent, just smile more often.

Researchers in the Czech Republic recently had people look at photographs of strangers with the intent of trying to guess their IQ's based on facial features. The results basically showed they were terrible at it.

But one thing it did show, people will think you're smarter if you're good looking and if you smile more often. Evidently if you smile frequently it exudes a confidence level that makes people think you're more intelligent.

Those people who looked angry or frowned more often were rated as less intelligent according to the findings of the study.

Basically what it boils down to, if you walk around scowling all the time you're going to be labeled as dumb.  But if you show off those pearly whites with a nice big grin most of the time, the average person will think you're smart even if you're a moron.

So smiles everyone, smiles!
