The Inner World of Outliers

At some point today I finished reading/leafing through Malcolm Gladwell's "Outliers". I take issue not with what he says in the book but how he says it. Do I think that some people are born in 'lucky' years where opportunity presents itself more readily? I noticed twenty-five years ago that Prince, Michael Jackson, and Madonna were all born in the summer of 1958. It's Gladwell's conclusions, or methodology that I take issue with. He cherry picks, particularly deeper into the book, where he's thin on validation of his hypothesis. Almost without exception he chooses men as subjects, and men that fall within his outliers paradigm. Some of his comparisons are infuriatingly spare on their criteria. I couldn't help but wonder if he was hellbent on justifying something in his own mind moreso than discovering a real truth.
I read Gladwell's "Blink" and "The Tipping Point", and both of those books are much better conceived and thought out than "Outliers". That might be the trouble. He wants to justify his own bit of outlier land, and the reader is led fairly far afield.
