Experts have finally noticed that average American IQ scores are slipping, and the explanations arrive like a well-rehearsed comedy routine. Less reading, more screens. Education systems that test the wrong things. Nutritional changes, air pollution, and the usual environmental laundry list. The article helpfully lists them all, then shrugs that no single factor explains the drop. How thoughtful.
To be blunt, they will always blame everything under the sun except the most obvious: demographics change. The national average is a weighted product of the groups that make up the population. When those weights shift, the average moves. Pretending otherwise requires treating the country as a fixed set of identical brains suddenly corrupted by TikTok and leaded gasoline. Convenient, if you prefer lectures about screen time over uncomfortable arithmetic.
The reverse Flynn effect is real enough in recent data. Verbal reasoning and matrix scores have trended downward while spatial abilities held or rose. States still show a spread from Massachusetts at the high end to Mississippi at the low end. Yet the preferred narrative remains the same: if only kids put down the phones and ate more kale, the numbers would rebound. Never mind that the same phones and diets exist in places where the averages have not collapsed in the same way. Never mind that group differences in cognitive distributions have been documented for decades and refuse to vanish under better schooling alone.
The comedy writes itself. Policymakers and commentators perform elaborate gymnastics to avoid naming the composition of the population as a variable. Screens get the monologue. Demographics get the silent treatment. The result is a public conversation that treats intelligence like a renewable resource that can be restored with better Wi-Fi etiquette and organic produce. Meanwhile the national mean drifts, the gaps persist, and the experts keep discovering new environmental villains with the enthusiasm of people who have misplaced their calculators.
Harsh? Perhaps. Funny? Only if you enjoy watching an entire intellectual class carefully step around the one explanation that requires no new study, just the willingness to count. Ah… the long term effect of migration from the 3rd world.
