So many competing things, could also be related to stress levels.

Stress has a profound impact on the growing body.

Also: IQ as a measure of cognitive development only makes sense in children.




> So many competing things

certainly, I just wonder about IQ. Of course IQ is itself an inexact proxy for things such as processing speed but the correlation does exist so something is going on there. Whether it's causation or not, who can tell.

I just think the idea is interesting. People often think of the body's ability to maintain itself as sort of set in stone based upon DNA, and of course there's truth to that. But we also know the body can learn, that's literally what vaccines do. So the question becomes, if the unconscious mind can strategize it implies better or worse outcomes based upon "decisions" and learning. Peanut Allergies are less likely to exist in populations that are around peanuts than those without. We know this, but I'm not sure I've seen anyone explain the mechanism that causes this to be true.

I'm also not a biologist so it's probably completely ignorant, but that doesn't stop it from being fun to think about.
