Is Einstein left-handed?

But handedness has its roots in the brain—right-handed people have left-hemisphere-dominant brains and vice versa—and the lefties who claim Einstein weren't all that far off. While he was certainly right-handed, autopsies suggest his brain didn't reflect the typical left-side dominance in language and speech areas.

How do lefties think?

Lefties may be able to use both sides of their brain more easily and efficiently. According to an Australian study published in 2006 in the journal Neuropsychology, left-handed people tend to have faster connections between the right and left hemispheres of the brain, which leads to quicker information processing.

This led him to formulate a “simple hypothesis…that criminals are more often left-handed than honest men, and lunatics are more sensitively left-sided”.

Why do left-handers think differently?

The brains of left-handers are different from those of right-handers, in that their brain lateralization – what people use the left and right sides of the brain for – is different.

Does being left-handed affect personality?

According to a small study published in the Journal of Nervous and Mental Disease, lefties are more prone to having negative emotions. In addition, they seem to have a more difficult time processing their feelings. Again, this seems to be related to the brain-hand connection.

How rare is a left-handed girl?

Are lefties more sensitive?

They found that left-handed folks get some perks when it comes to language capability.
