As soon as the author starts getting into statistics, there are so many bad assumptions being made that the conclusions being drawn are just ridiculous. Just as a first pass, the fact that you are widely read does not mean you are a good writer. Secondly, it's obvious that genetics don't determine everything about someone's life (surely a writer would recognize that writing is not wholly an inherent skill?), so going off on a tangent about what it would mean if it were is not actually all that interesting.

Didn't get much further than that.
