Dawn of the dumb – scientists say IQs are beginning to fall in the UK

The reason given in the article is that over the past century IQ scores climbed in western nations due to improvements in nutrition and health, but since those have basically plateaued, the effect is wearing off. I wonder how much of it is due to making a nerf society where the dumb aren’t allowed to kill themselves off before breeding. Yes, yes, IQ doesn’t seem to track well with genetics, and intelligence seems to be driven more by environment and upbringing… but let’s face it, genes or no we seem to be driving a society more in the direction of dumbth via culture.
