??? If so, then the typical debate is very poor. Nature vs. nurture may be the common words used, but anyone with even a meager understanding of it realizes that it's actually a genes vs. environment issue, and that environment includes much, much more than "factors you as a parent or a society can control."
In fact, the linked article even acknowledges that: "Everything not chalked up to genetic control tends to get attributed to diverse environmental factors, ranging from nutrition to stress to idiosyncratic social interactions. It’s a line of thought that 'suggests that it must be something outside the organism,. . . "
The article seems to want to posit random noise as a third factor (beyond genes and environment), but I think the same point would be made by positing that recent studies suggest "developmental noise" may occupy an especially privileged role among environmental factors. Noise clearly falls into broad penumbra of "environment", which also includes many other random factors.

There's no reason to expect it to be exogenous; it's very easy for the genotype to specify that an outcome should be more or less unpredictable.
- patrec 7y agoSince what you wrote is true (you could have a gene where one allele increases observed phenotypic variance and another decreases it; in fact I'm pretty sure such genes exists), I suspect the people downvoted you did so because they'd rather not think clearly about these matters.
- thaumasiotes 7y agoIt's not quite at the level of a single allele, but e.g. I understand that the same mutation related to eye-color results in a lot more color variance in females than it does in males.
- patrec 7y agoAnd male vs female variance in general would appear to be strong evidence that something is going on.
