From the above FT article:
research shows that left-handers are more likely to suffer from language disorders, autism, dyslexia, "schizotypal behaviour patterns", seizures and post-traumatic stress disorder.
I'm quoting that lest we forget there's a neurologic basis for left-handedness, which is not fully understood. Provided that scientific curiosity is kept alive, I think the prudence of a sentence like "We do not have a theory that reconciles all of these findings" is commendable. You're clearly a dangerous pinko commie pragmatist.
In 1998, a study suggested that approximately 7 to 10 percent of the adult population was left-handed, and that left-handedness is more common in males than females.
