—“The Flynn Effect postulates that measureable intelligence(measured) is increasing over time (but not necessarily (g) – neurological performance). However, as an environment becomes optimal, a plateau occurs when general growth becomes largely determined by genetics. There is evidence that such a plateau is occurring for intelligence in countries with optimal social environments. In the United States, examination of adult Wechsler test scores between normings indicates a reduction of the FSIQ increase such that average FSIQ would plateau about 2024.”–

The flynn effect is caused largely if not entirely by improvement of literacy at the bottom, thus un-skewing the numbers.

Meanwhile it is reversing as the reproduction of the bottom because of redistribution transfers reproduction from the middle and top to the bottom, reversing the average IQ. In the USA this is reaching a critical threshold where it will not be possible to maintain a first world economy.

Likewise expression of sex difference in cognitive biase and preference diverges as constraint decreases.

Likewise if the family is the priority of informal and formal institusions and the resulting policy then the sexes and individuals have more in common. But without such, we see rapid divergence of preferences and ‘magical thinking’ between both the sexes in the aggregate and individuals. Meaning that the family is the foundation of the society and polity but the individual is only lrelevant in the contest of the family. Which is … going to be problematic.
