Intelligence is a well-defined quantity like temperature, and it follows a genetic architecture like height: thousands of genetic variants of small effect size. Which setup does indeed give you a binomial or normal sort of distribution, justifying the norming as more than a mathematical convenience.

distribution of what? Still no quantity defined.

As a physicist it sounds about right. Temperature is tricky to define in non-stationary systems (aka. "real world").
