>>109482758There's evidence on both sides of the aisle for that. True the Flynn effect shows an increase in measured IQ, but that doesn't mean IQ has rising, just that people are doing better on IQ tests, which isn't the same thing. It's entirely possible that people are doing better on IQ tests because it's entirely feasible that people who grew up in public education are more likely to be better at taking tests in general than people who grew up labouring, the same way it has been shown IQ testing can be "learned"
Even then, the Flynn effect "stopped" a quarter of a decade ago, the same time people stopped getting taller, suggesting nutritional causes. Your statement is straight up wrong in response to his seeing as his was about modern people getting stupider because the average IQ HAS dropped since it stopped. Modern people do better on IQ tests compared to people from 100 years ago, yes, but they do WORSE than people 20 years ago so you're simply full of shit.
Other pieces of evidence are the decline in reaction times compared to Victorians, assuming their measurements were accurate, along with the fact that there is an established correlation between reaction time and intelligence.
Generally the evidence points to people are getting genetically stupider but nutritional advances at the time acted as a band aid, one which has peeled off.
But of course you're an "I fucking LOVE Science!" fella who doesn't actually look into things he hears about before he repeats them and treats it like scripture. Low IQ kid.
