Apparently there\’s a gene that causes being a lefty.
The gene does not automatically make the carrier a Lefty; rather, it triggers the adolescent brain\’s reward mechanism in the presence of novel experiences and viewpoints. The treatment is simple: lock teenage sufferers in a drab room, furnished with the works of Hayek and Friedman. True, their social skills will be somewhat stunted. But the benefits will last a lifetime.
Looking around me (and looking deep into my own soul) umm, isn\’t that what already explains those righties that exist?
