<p>^He did state the obvious, but I thought he did a solid job of compiling all these studies and such into a logical argument. And it’s obvious once you read his explanations. But not very much before. How many of us knew beforehand that summers were such a detriment for academic achievement, that the chinese numbering system contributes to their adeptness at math, that many airline crashes were so dependent on lack of proper communication due to societal respect? Even if you suspected some of the things he argued for, did you have much evidence to support it? And if you looked for the proper evidence in google search or in some database, would you find it an abundance of support quickly and effectively? Probably not. Yes, it got repetitive. He could have written a twenty page essay (or less) that contained all of his claims. But would you buy his argument if he didn’t harp on each point so much? Would you be satisfied with him saying that “birthdays play an important role in success” and leaving it at that? No. That is not an argument, it’s a generalized, unsupported claim on it’s own.</p>
