There are so many other factors, you’re probably getting mostly noise there. For instance: I read somewhere that depending on whether babies drink breast milk or formula, they may lose 10 points (to formula) - the reason stated was lack of omega 3. What about lead paint chips? We have banned lead, that should increase IQ—after an initial decrease when lead paint began to be used. (There’d be a similar increase / decrease cycle with the invention of formula.) The point of these two is that as we learn more, we may be preventing a lot of things that previously caused children brain damage. And then there are other health factors which we’ve improved. In the great depression, I read 10% of the population starved to death. Starvation, for those who survive it, can cause brain damage. Were there other starvations before this, that had stopped happening? When did helmets become popular for people riding bicycles and skateboards and such?
There are just too many factors.
Heh, and I read somewhere that here in America, the Flynn effect has stopped. O.O
1) Sure. I’m not claiming the Flynn effect is genetic; I’m disputing the common claim that it can’t be genetic.
2) Whether the Flynn effect has stopped or not is an area of ongoing dispute; some studies suggest it merely paused for a while. And if it has ended . . . that might merely mark that America’s reached the new equilibrium point under urban infidelity conditions.
“I’m disputing the common claim that it can’t be genetic.”
Oh, sorry.
I have found out the hard way, myself, that it’s really best to start with a single sentence that makes one’s point clear in the very beginning. Maybe that would help your commenters respond appropriately.
