> Net worth. It's a pretty good proxy.

TLDR; I have met quite a few very high net worth individuals, their spouses and offspring. Hundreds of them, actually. I have not been impressed overall with their intellectual capacity for learning important and lifesaving knowledge in preparation for life-changing natural survival conditions which are outside of their daily routine. The same has been true at the middle and lower income distributions under similar circumstances. I am neutral about the future IQ of the population of any of their descendants, poor or rich.. There are many other factors at play.

The long version:

That has not been my admittedly anecdotal experience among high, moderate, and average net work individuals and small to large congregations of those net worth groups in North, Central, South Americas, East Asia, the Pacific Islands, the UK and Northern Europe. I haven't found any specific factors resulting in concentration of above or below average IQ individuals within any of those groups. I have traveled much; been in direct leadership positions among high net worth individuals' on board of directors, and have been in direct contact with significant groups of low net worth populations in both labor and non-profit support roles. I do confess to not having conducted specific research in the IQ to net worth among those groups, so this is just an informed opinion.

So, I will yield on the sole point IFF net worth is assumed to be a strong proxy for high IQ; then we might be headed in a smarter direction in the portions of the general population resulting from those families. I do agree with the distinction that the proposed mechanism in the film Idiocracy is not what is occurring. It does however seem apparent that due to many different mechanisms we may be in for a significantly dumber future, and on that we also agree.

It may be that among the high net worth populations; there may be a factor within the high IQ subgroup that is aware of the complex difficulty for the planet due to excessive and wasteful overconsumption and the aggregate demand that additional population stresses the situation. That subgroup may be choosing to self deselect for reproduction, and that subgroup may be among the highest fraction of IQ. It doesn't appear that this aspect was in the study you referenced, nor in any of that study's sources' research. Did I miss that component?
