Yeah, the domestication of the silver fox is one of those really cool stories but also—to someone as astute as you—is a bit of a cautionary tale about unintended consequences.

There was nothing unintended about it: the original hypothesis was to see if those changes were interconnected as they seemed to be in various domesticated animals.
The effect of domestication was large enough to be observed, one might say, with the naked eye. As I keep asking in this page in response to all the groundless fearmongering: do we observe, with the naked eye, huge increases in pathologies of various sorts with people of extremely high intelligence? Or do we observe only some small increases in some problems and also indications of net benefits like increased longevity?
