Expert Says: Intelligent people go to bed late, leave a mess everywhere, and use bad language
To be fair, stupid people do exactly the same things.
Also left handers.
There are disproportionate amount of left handers among high IQs and low IQs (upside down bell curve).
Is that because they (more than right-handers) are more easily and distinctly split into groups of those who give up easily and those who stick with something to find a solution?
I have no idea WHY this is the case.
I do know that in general, left handedness is about 10% of the population and I had classes where 1/3 of us were left handed.
