IQ scores in most of the Western world began reversing sometime from the 90s to early 00s. [1] That link is for the US but similar stuff has also been observed in most of every Western/OECD nation. By contrast they're still rapidly increasing in the 'Global South'. You'd expect this to manifest in reduced test scores and reduced quality of outcomes across a breadth of fields over time paired with the inverse happening in countries seeing gains. And that does not seem inaccurate.

Why this is, is an interesting question but it hits on too many taboo topics. Though perhaps rational discussion becoming taboo is itself a part of the reason. When you accept reality, whatever it gives you, you're obviously going to have a far more rational population and better outcomes than one that insists on bending reality to fit a desired narrative, even when it obviously does not. After all this is precisely what brought Greater Arabia from the center of education and learning in the world to rather the opposite. It wasn't religion, but letting ideology dominate reality instead of the other way around.

I wonder to what extent demographic shifts account for the observed reversal? It would be interesting to tease out what happens where composition remains constant, i.e. Poland. Though I doubt this explains the entire effect.

seems like the Flynn effect doing its thing just as it did in western countries in the 20th century.

I'm sure you fail to see the contradiction in claiming that "rational discussion" is a taboo while clearly not stating your hypothesis.

In the same vein, your hypothesis obviates the fact that "rational discussion" in topics of interpreting social studies requires building out on a ton of assumptions that are weakly held and the reason why the social scientists abstain from giving clear-cut answers is because the topic has too much depth and nuance to make strong statements with confidence.

I get the feeling you want to blame "woke" ideologies for this decline. Please correct me if I'm wrong.

In my opinion we just have it too easy nowadays. Too much entertainment, screens and not enough challenges to keep kids thinking they need to be as sharp as they can be.
