Are left-handed people smarter?

Friend of mine pointed me to this article. Power to the lefties!

As per MSN news

Yep. According to researcher Alan Searleman, southpaws have higher IQs, solve problems better and enjoy more extensive vocabularies than righties. Lefty cases in point: Isaac Newton, Benjamin Franklin, Albert Einstein and Pablo Picasso, for starters. Not to mention every U.S. president since 1981, except this one. (George W. Bush)

Can't seem to get the links to work for some reason.

Take heart, righties: Searleman's study also found that lefties have worse memories than their right-handed peers.

The memory thing is sooo true.
