Reasonably close within subpopulations to about ±1.5–2SD, which covers most practical cases, but because environmental effects can harm genetic baseline, and maybe other reasons, the extremes tilt left.https://twitter.com/chrylis/status/1221947765661556736 …

Also there's an effect apparently unique to European males of a significantly wider (maybe +10 "point") SD, apparently symmetric but highly relevant in context.
