As noted here earlier this week, Art DeVany has written extensively on the specious basis of the conventional wisdom that Barry Bonds’ steroid use allowed him to break the Major League Baseball home run records. DeVany responds again here:
[The conventional wisdom that Bonds’ steroid use allowed him to break the MLB home run records] does not fit into any standard model or argument that has been offered as an explanation for his “departure” from the norm. There is no norm, which [the conventional wisdom] and most others advances.
Genius does not follow a process that can be normed. My argument is simple and is in the paper. Basically, most people are using an implicit normal distribution model of HRs and they claim that his performance cannot come from the model. Hence, he must have taken something. This is wrong. His performance is within the natural variation of HR hitting, but the model is not a normal distribution. Why should it be? A normal distribution applies when most people are close to the average. This has nothing to do with HRs. If you role snake eyes three times in a row, do you think there has to be an explanation? No, it is in the variation. Just chance. The dice are not on steroids.
What is worse is that people who claim “he did it and it worked” don’t know much about the physiology of steroids. They weaken connective tissue and interfere with concentration when they are taken in large doses. They primarily increase protein synthesis is ST muscle fibers, which are no good for hitting HRs. Lastly, most people who formulate the argument do not have a falsifiable hypothesis, and this is not science. They take his performance, which no one else has ever done, and claim that you cannot prove that it was not due to steroids. “He took steroids and therefore hit 73 HRs” cannot be falsified. Because the conclusion is true, the statement is vacuous. It is true no matter what the premise.

Update: Professor DeVany compares Bonds and Hank Aaron’s home run-hitting prowess to that of an average MLB player here, and provides additional comments regarding Bonds here. Professor DeVany’s paper on home-run hitting is here (pdf).
