My personal experience (hooray for anecdotal evidence) is that this is correct. Any generational Flynn effect is going to be pretty small and easily swamped by other factors. For example, I'm pretty sure that students at my university have actually gotten a little worse at math, on average, since I arrived 15+ years ago. Obviously that's not because they have lower IQs. It's much more likely to be the result of atrocious and declining K-12 math education.This is accurate. Flynn (the guy who discovered the consistent rise in IQ) was on an interesting podcast discussing his observations. Not all areas of intelligence have grown and the demands made on the brain by the environment most definitely create generational strengths and weaknesses in intelligence.
I don't teach any courses that require major research papers, but when I talk with colleagues who do, they almost all seem to think that today's students have a more difficult time crafting an argument or even just following along with one. Given the norms of social media, I don't see any reason to find that observation surprising.
