If I enable reader mode on this article on my iPhone, I get an AI summary instead of the article text. I’d it the sure doing that or my phone? I hate it either way as there’s no way to read the article in reader mode

try this maybe?

I find things like that hard to perfectly square with observations like the Flynn Effect (“the substantial and long-sustained increase in both fluid and crystallized intelligence test scores that were measured in many parts of the world over the 20th century”): https://en.wikipedia.org/wiki/Flynn_effect

Why? Draw the line backwards, and in a couple of decades you are down at 0 IQ. That's clearly absurd, you can't draw any conclusions of IQ significantly before 1950 from how the line behaves after 1950.

And that’s because IQ is a statistical distribution, not an absolute measurement of intelligence.

If everyone suddenly gets twice as smart as before, nobody’s IQ changes.

For any given IQ test, the norming sample is taken once. So if everyone gets twice as smart as before, everyone's IQ, as measured by any existing IQ test, would go up.

True, but irrelevant.

Or, false and irrelevant.

People's scores on yesteryear's tests rose over the distribution when the test was initially taken.

Firstly, this is completely orthogonal. But it's also improper reasoning. If Neanderthal had bigger brains (they did) or had different cognitive abilities, there's a chance they were baseline smarter than homo sapiens at the time. Being perhaps a little smarter doesn't mean you win the evolutionary game. There are so many factors at play.

> Being perhaps a little smarter doesn't mean you win the evolutionary game. There are so many factors at play. Considering most human groups have a % of Neanderthal DNA, they didn't exactly lose... Based on the % of Neanderthal vs. Sapien DNA, it seems Neanderthals were simply outnumbered.

What does it mean to lose evolutionarily if not be outnumbered?

Ants won over humans? Worms?
