when I wrote the article I was more convinced than I had been before the article that genes were unimportant completely unimportant and by the time I wrote the book I came to feel that there was sort of two extreme camps one that felt genes have no influence on performance and another that I'd say the other extreme wasn't that practice has no influence as uncontroversial so I think one extreme was only practice matters and the other extreme was practice and genes matter I think that is not as extreme saying they both matter which and my bias is the latter my bias is just that I mean that's what the evidence shows yeah
