What happened to the Flynn Effect?
Have you been following the Flynn effect research? It's dead, Jim.
My guess is that with selective mating, the tail has thickened at least at the top end.
We don't see it.
With better nutrition, longer lives, an increasing percentage of scientists, we should expect the age of productivity to go up.
None of that really follows. Better nutrition may change the baseline without affecting the arc of mental growth and decline; lives can be extended likewise; an increasing percentage of scientists doesn't help, and arguably by diminishing returns may hurt any average. Further, even if we established that any effects existed (like the former Flynn effect), that effect would have to overcome the underlying aging/delaying trend. It hasn't yet*, so why do you expect it to do so in the future?
* Note, by the way, this implies nutrition and life expectancy are pretty hopeless: we already reaped all the gains there were from iodine and cheap calories, and life expectancy increases are decelerating in the US.
Do you think they're all going to rush off to work at Walmart, or all become lawyers?
Yeah, pretty much. There's a lots of non-science jobs, you know, and with tenure disappearing, where do you think all those grad students are going to? Where did smart people go back when 1% of the population went to college? All sorts of places.

Could you amplify that? It's stopped happening, or it never did?
