I did a paper on cerebral organization and handedness and it is true that lefties are slightly over-represented in "abnormal" populations. But, it is a big question mark as to why with lots and lots of possible directions to go in to answer the question.

One big question is what caused the handedness in the first place (there are lots of guesses on that), plus to what degree is a person left-handed or ambidextrous--lefties tend to be more ambidextrous (if you think of handedness on a scale from totally left-handed to totally right-handed). Those that I call "profoundly" left handed use their lefts for everything, and most "lefties" don't do that, and many lefties are not "left dominant" (ie, use their left hand to throw, left leg to kick, left eye to wink, or bat or bowl or golf left-handed, etc.). Even how a left-handed writer holds their pencil (curled above the line they write on or more even or below the line) is studied as a clue to cerebral organization.

Lefties are also slightly more prevalent in artistic profession, and, for some reason, as architects.

I am a lefty for writing, and do just about everything else with my right hand, and am right-side dominant.
