From the Ethics Alarms glossary: “Signature Significance: The concept is the creation of baseball statistics genius Bill James, who applied it to baseball performance. Signature significance posits that a single act can be so remarkable that it has predictive and analytical value, and should not be dismissed as statistically insignificant. Thus, in James’ example, certain outstanding pitching performances can prove that the pitcher involved is an outstanding one, because average pitchers literally never reach such levels of excellence, even as a one-time fluke.”
As regular readers here know, Ethics Alarms often employs the term to describe an extreme ethical or unethical act that similarly reveals the true character of the individual responsible for the conduct, and that can be reliably and fairly used to predict future conduct and trustworthiness. To cite a recent example, SCOTUS Justice Sotomayor’s hysterical dissent in Trump v. US is, all by itself, proof that she’s not qualified to be on the Court and a poor jurist. A competent judge wouldn’t write such an opinion, not even one of them. “Well, it’s just one bad dissent” doesn’t let her off the hook. The dissent is so terrible, emotion-wrought, wrong on the law and logically flawed that i a competent Justice couldn’t possibly put her name on such offal, even on the most deranged day of her life. It’s signature significance.
But as baseball giveth, baseball taketh away. Yesterday, the game presented a vivid example of how what seems like signature significance sometimes isn’t.
Jose Miranda of the Minnesota Twins, a 25-year old infielder, tied the MLB record for most consecutive hits. He got his 12th hit in a row, raising his batting average to a near league-lading .331. Amazing. No player had done that in 70 years.
