Our national problems are often directly due to low IQ among much of the population.

But IQ can be boosted, or at least protected from harm. It's not entirely determined by genes. So here are some actions we should take as a country to boost the national IQ:

- Eliminate fluoride from all water supplies, because fluoride provably lowers children's IQs.
- Eliminate all vaccine requirements, because vaccines cause autism. First eliminate aluminum and mercury in vaccines.
- Reduce lead exposure, air pollution, and polyfluoroalkyl substances (PFAS)
- Promote oily fish, such as herring, anchovies, salmon, sardine, mackerel, trout, which are known to help brain health.
- Teach new parents about the known methods of boosting children's IQ, such as reading to their children.
- Promote reading real paper books, which require more concentration than reading blurbs on the internet.
- Promote intellectual competition like chess, crossword puzzles, and memory contests.

We concluded that prolonged intensive training in creative problem-solving can lead to substantial and positive effects on intelligence during late adolescence (ages 18–19). ...

Nowadays, it is generally accepted that the heritability of intelligence increases from about 20% in infancy to perhaps 80% in later adulthood. This leaves plenty of room for environmental effects, especially within the school-aged populations.
