"The point here is this: Were it not for those “disordered” genes, you wouldn’t have extremely creative, successful people.  Being in the absolute middle of every trait spectrum, not too extreme in any one direction, makes you balanced, but rather boring.  The tails of the spectrum, or the fringe, is where all the exciting stuff happens.  Some of the exciting stuff goes uncontrolled and ends up being a psychological disorder, but some of those people with the traits that define Bipolar Disorder, Schizophrenia, ADHD, and other psychological conditions, have the fortunate gift of high cognitive control paired with those traits, and end up being the creative geniuses that we admire, aspire to be like, and desperately need in this world.

…If we were to be able to identify the genes for Schizophrenia, or for Bipolar Disorder, or for ADHD… would we want to eliminate them? If we were making a “designer baby”, would you choose those genes to be added into your child’s genome?

I say yes."
