Why our IQ levels are higher than our grandparents' | James Flynn
Why Hacker News recommends it
HN recommends it as a clear explanation of why generations think differently and why IQ scores have risen.
What it is
Moral philosopher James Flynn explains the Flynn effect, the steady rise of IQ scores across the 20th century. He argues the shift reflects a move toward abstract, hypothetical thinking as cognitively demanding professions grew.

I disagree. I think stories like this are important. They teach you to take a hypothetical scenario seriously. It teaches people to ask "what if X were true?" and to seriously consider the ramifications. This is a springboard into abstract thinking. Without people taking the hypothetical seriously they will want to deal with concrete things and will have trouble with abstract reasoning. Imagine you were trying to have a discussion about racism with someone. You would tell them "How would you feel if one day you woke up black and people were biased against you due to your skin color?" They would tell you that it's the dumbest thing they've ever heard. Who have you ever known that woke up with

This is an off-topic point, but perhaps this TED talk by James Flynn might give you a perspective to understand why your parents and grandparents tought: [this video] It posits the idea that the way of thinking back then was different, because they had to overcome different cognitive challenges from us today. This would shape how people back then viewed the world.

I think TED talks used to be better. Perhaps it's nostalgia, but I really enjoyed TED talks in the past. Martin Rees talking cosmology, Richard Dawkins talking about why the universe seems so strange, James Flynn talking about the Flynn effect[0], Barry Schwartz talking about the paradox of choice etc are enjoyable to me even today. There are many others, but I've not enjoyed as many in the recent years. [0] [this video]

You mention that men under 70 lack a certain something. Are you sure it isn't that men have gained something they didn't have in the past? I have thought a lot about how the human condition has changed over the years. I feel the most important change is modern human's ability to think in the abstract. If you were to ask a pre-modern human to group a chicken, a crow, a stick, and a tree. They might group the chicken and the stick together because they would use the stick to kill the chicken and make a meal. Whereas a modern human would most likely group the chicken and crow, and the stick and tree together. The tendency to think abstractly has exploded over the last hundred years or so, and i

I think James Gleick is missing a lot of context her. James Flynn[0] also gave a TED talk and mentioned those interviews[1]. Apparently it's based on interviews done by Alexander Luria[2] and he put those in writing in one of his books The Making of Mind: A Personal Account of Soviet Psychology (Chapter 4[3]).
