Left Handers R Cleverer?

Collected Little Arielle's studio pic earlier on and saw the photographer's kid using right hand to write and I was so envious.

Guessed what....the photographer was telling me that she was trying very hard to get her son to use his left hand instead of his right hand. She said that left handers are cleverer as they know how to use the other side of the brain.

Hmm....so is my girl really cleverer??
