Well duh, there was a study on London cabbies who had to take a test known as "the knowledge", and it was found that they had significantly more growth in their hippocampus. So obviously the reverse would probably be true. I remember I used to chunk numbers in 3 to 4 digit groupings because back in the day that was how I naturally memorized phone numbers, successive generations probably can't rely on that tactic as much simply because there's so little need to retain the phone numbers in memory with the invention of smart phones.

Sure, but that feels like an equivalence of just saying "people without a college degree are less mentally developed than those who do." Memorizing the street system of a city the size of London is obviously hard. But is it important to actually do so in a world where it's not essential? I feel like the implication of a lot of these articles is "people aren't learning X thing that's not essential now, and instead are learning TikTok Memes." Which may not be wrong, but how much of a problem actually is that? Obviously, a century ago, there was no slack for almost anyone to not carry their weight in society. Everyone needed to know how to farm and start a fire, and plenty of other things most people don't know any more. Pre-teens had to work important jobs because otherwise people didn't eat. Obviously things have swung away from that, but the question is how far away from that is a good thing vs. just allowing people to indulge in vices.
