The news today informed me that scientists have located the first gene that influences handedness. Good, I thought, a genetic basis for being left handed is much better than the other theories, which as far as I understand it, are basically different types of brain damage. Then I looked at the smaller print... This candidate gene only makes someone slightly more likely than average to be left handed (i.e. it's likely to be working in conjunction with other genes or in fact brain damage), AND the same gene is also associated with a higher risk of psychotic illness. Ditch the brain damage and gain psychosis - lovely.
