These are very, very good points. Neither side can be proven or disproven. You also raise a good issue about how falsifiable the claims are. To me, the problem is really that we're working for different, yet equally valid, definitions of talent. tal·ent [tal-uhnt] Show IPA –noun 1. a special natural ability or aptitude: a talent for drawing. 2. a capacity for achievement or success; ability: young men of talent. I, along with the others supporting the info from the Talent Code, am dealing with number one. I don't believe anyone is born with a natural ability for music, sports, or any other endeavor. The other side working from the 2nd definition. A capacity for achievement. Height does not affect your actual skill for the game of basketball, but it certainly affects your capacity for success. So, both opinions are valid. However, I truly believe most people think of talent as the first definition.
