My mother would tell you otherwise. My worlds were all in that big bag of bricks. You could collaboratively build machines and landscapes, then tell stories within that transient place. And once you got into "Technics" sets, the mechanical components were actually quite sophisticated. I've put in thousands of hours into those little plastic bricks.
Ok, but the very fact that you write «mother» suggests a certain "demographics", while the title of the actual article is 'Looking for Flynn effects in a recent online U.S. /adult/ sample: Examining shifts within the SAPA Project'.
I wonder if any of this is related to Covid. Perhaps it afflicted parts of the brain differently. That doesn't explain why any parts would get better though.
