I want to be sympathetic to Singal, whose writing always seems to generate shitstorms disproportionate to anything he's actually saying, and whose premise in this piece I tend to agree with (as someone whose politics largely line up with those of the outgoing editor in chief, I've found a lot of what SciAm has posted to be cringe-worthy and destructive).

But what is he on about here?

Or that the normal distribution—a vital and basic statistical concept—is inherently suspect? No, really: Three days after the legendary biologist and author E.O. Wilson died, SciAm published a surreal hit piece about him in which the author lamented "his dangerous ideas on what factors influence human behavior."

(a) The (marked!) editorial is in no way a refutation of the concept of the normal distribution.

(b) It's written by a currently-publishing tenured life sciences professor (though, clearly, not one of the ones Singal would have chosen --- or, to be fair, me, though it's not hard for me to get over that and confirm that she's familiar with basic statistics).

(c) There's absolutely nothing "surreal" about taking Wilson to task for his support of scientific racism; multiple headline stories have been written about it, in particular his relationship with John Philippe Rushton, the discredited late head of the Pioneer Fund.

It's one thing for Singal to have culturally heterodox† views on unsettled trans science and policy issues††, another for him to dip his toes into HBD-ism. Sorry, dude, there's a dark stain on Wilson's career. Trying to sneak that past the reader, as if it was knee-jerk wokeism, sabotages the credibility of your own piece.

Again, the rest of this piece, sure. Maybe he's right. The Jedi thing in particular: major ugh. But I don't want to have to check all of his references, and it appears that one needs to.

term used advisedly

†† this is what Singal is principally known for

The Wilson article really does say:

> First, the so-called normal distribution of statistics assumes that there are default humans who serve as the standard that the rest of us can be accurately measured against.

That’s at best sloppily written, regardless of what one thinks about Wilson. The normal distribution is a mathematical tool; it doesn’t “assume” anything about some particular concrete topic like measuring humans.

The normal distribution does indeed make some assumptions. Certain natural qualities tend to be notmally distributed like height, but other things like net worth are NOT normally distributed because of feedback loops. The choice of distribution either makes an assumption or validates some other prior assumptions.

Thr choice of using a normal distribution vs another mathematical distribution is not purely a mathematical device, the choice either reflects some assumptions (which one would quickly see if they're valid or not generally).

An interesting case in point for me is when a lot of mathematics assume bell curve distribution in stock market price distributions, like the black scholes option equation does, and it turns out to not really be the best fit. It sort off almost works, but systematically underprices extreme events.

This is what can happen when your assumed distribution turns out to be wrong.

So far though, I haven't heard of refutations that height or IQ (as measured on standardised tests and processed in prescribed ways) are indeed bell curve distributions.
