tendency of crested societies to observe dramatic declines in their birthrates is spooky going through the decline of Greece atm whats wrong with people get out and breed why dont you

It doesn't though. It says that finding such people (good) and sending them to college (Breeder's equation) after which they don't have kids (??) is an IQ shredder. Finding diamonds in the rough just serves to make it more effective.
-
but it extrapolates that to the level of the whole society, implying that reduced fertility among talented social climbers has a societal net of "shredding IQ". I don't think that claim is justified because it discounts influx of new talented people.

Say we had a rule: you must be "this tall" to go to the city. City would get tall, country short, no? Now: city has one kid and country has three. We've only been doing it for three generations. Breeders equation can tell you the rest.

There are free parameters. The direction of the constraints couldn't be clearer from the data.
-
I don't think it's as simple as "city would get tall, country would get short". Yes, city would get tall. No, country wouldn't necessarily get short. It's not nearly as closed a system as the city, and it's supply of tallness is not so finite.
-
oh you get paid more in the city, are awarded higher social standing, and have more sex partners. tall people tend to choose the city. even if they have short parents. maybe especially if.
-
granted. I find the argument that city gets influx of tall immigrants, and net increase in local tallness over time, to be coherent. It's the other half I'm questioning. Country does not necessarily get "drained".
