By the way, no statistician would dispute my statement that Bonds' batting average over the hypothetical 1200 additional at bats would be close to his lifetime average. The walks they susbstitute for were distributed throughout his career - remember, he had fourteen 100+ walk seasons - and both the total at bats (9000+) and walks (1200) are more than robust enough to provide statistically meaningful results.
I know you're a lawyer and are not in the business of making prognostications, but many people are. And while it is true (and trite) to say that no-one can know exactly what might have happened, that isn't the same thing as saying we don't have any idea at all. In fact, prognosticators handle the problem of uncertain outcomes by assigning probabilities to each. In this case, the probability that Bonds would hit for an average much different than his lifetime average would be so remote it could, for all practical purposes, be considered nil.
Well, it's hardly surprising that statisticians would come down in favor of the reliability of statistical analysis. I disagree that no statistician would disagree with you, but whatever. Zacky Farms would probably claim, if asked, that Wade Boggs' ritual of always eating chicken for his pre-game meal added at least 25 points to his lifetime ba%.
I agree that statistical analysis is not worthless. But neither is it the case that the likelihood of the results being different from what you contend is "nil". You implicitly assume there is no relationship between pitches not swung at and pitches that are hit. There's little question, however, that the farther from the heart of the strike zone the pitch, the less likely it will be hit for a base hit. That's the point of the Williams chart from The Art of Hitting.
As a lawyer, I often do have to help clients make decisions about future contingencies. But central to what I do is cutting through falsely authoritian bas and distinguishing conjecture -- even good conjecture -- from concrete fact. I spend a good deal of time poking holes in the expressed opinions of so-called experts in statistics, economics, etc., who spin out fancy calculations where all the numers seem to add up but in fact are all dependent on unstated, and unsupported, assumptions. It's one of the fun parts of my job.
