The problem with specs

As someone of the four-eyed persuasion, I have often been told that my spectacles make me look serious/studious and there's no doubting that people tend to think that those who are sight-challenged are intelligent and yet I haven't come across any empirical evidence to support this assertion. Spectacle wearers are expected to engage in intelligent discourse and impart pearls of wisdom - I expect many people had a reality check once Sarah Palin, the Republican Party's nominee for Vice President, opened her mouth.
