Honest question that keeps bothering me.

In the absence of reasonably strong natural selection pressure to select for IQ, how could IQ not be falling over time?

Conscientiousness and having long-term time horizons is dysgenic. People afflicted with those traits tend to reproduce less, and, to the extent that they're heritable, the genes coding them will gradually decrease in prevalence in the gene pool.

I’ve floated this idea before especially in the context of ADHD being framed as a disease because it has social costs, personal costs, and causes disruptive behavior. That may all be true but people with ADHD also have more unprotected sex and the vast majority of western society is wiping themselves out on account of not having enough unprotected sex to sustain themselves. It’s just that anything which interferes with utilitarianism and hedonism is framed as a disease.
