Left handed people - are they more intelligent ?

Question

i got the impression that left handed people are on average more productive

Answer 1

I don't think so.  More-so than which hand one writes with, I think how diligent/intelligent someone is has much more to due with personality and genetics.

What about the ambidextrous people?  I would think they're using both hemispheres of their brain fairly equally.

Answer 2

Well, I'm left-handed, and I'm not intelligent whatsoever.

However, I have remarked left-handers are the weirder ones who are more out there and do crazy, unreasonable things.

Answer 3

Back in the gap in Salem if you were left handed, you were put to death do to suspicions of witch craft or being possessed by the devil himself.
