Proofiness

This is actually a 4.5 star review with two 1-star deductions for howling errors that seem to stem mainly the author’s self-regard for his own mathematical savvy and the kind of “I’m clever in this area, so I must be clever in this area too” bias that trips up so many.

Overall, it’s a good update of the themes from some better but older books in the genre such as “Innumeracy” and “A Mathematician Reads the Newspaper” and Jordan Ellenberg’s “How Not to Be Wrong.” Chapter 7, “Alternate Realities” about the misuse of statistics in the criminal justice system is especially worthwhile and important, and the three short appendices explaining various examples of mathematical errors are quite good.

The deductions are for an early comment accusing Al Gore of cherry-picking data in his famous slide-deck presentations by showing what the Florida coastline would look like if the Greenland ice sheet melted, causing see levels to rise 20 feet. Seife notes that Gore is right to warn about sea level rise — but he wrote “It’s just that sea levels aren’t going to rise twenty feet anytime soon.” Here in 2024 — but also in 2010 — there was lots of evidence that our models of the effects of climate instability are persistently and systematically UNDERestimating both the pace and severity of changes. It reads as if Seife was dying to find an example of cherry picking that he could hang on a Democrat, so he simply asserted something that, alas, seems less certain every day, that we needn’t concern ourselves “anytime soon” with what a world without Greenland ice would look like.

The second star is deducted because Seife does only the most superficial gloss on the math of voting methods and ends up saying that it’s all just sport and that we like third party spoilers because it makes elections more interesting. Instead of noting that the entire gerrymandering problem he spends significant time covering is the result of the arcane single-member district system that is not constitutionally required, Seife simply asserts that we can simply use non-partisan redistricting commissions to abolish gerrymandering … which ignores the consequence of self-sorting, which is giving white rural voters a significant over representation in the US House to go with their significant overweight in power through the US Senate. Seife attacks ranked-choice voting and asserts — in direct contradiction to substantial evidence — that voter errors would “go through the roof” if ranked choice ballots are adopted.
