Jason Y: “Mark my word though, that a bad environment will see NO improvement even over a 1000 years!”
Phil: You forgot something, time is a resource. Second, it’s been noticed in the “Flynn effect” with Blacks that it stopped.
According to my latest information from Bermuda, the Bahamas, Dominica, Kenya, the US and the UK, the Flynn Effect, or whatever it is, is ongoing in Blacks.
Blacks now match Whites on an IQ proxy in the UK, and Half-Black mulattos now match Whites on an IQ proxy in Bermuda.
And in the Bahamas, more or less pure Blacks (9% White) seem to have made some serious IQ gains. Their IQ’s are now 93, whereas on a genetic basis, we might expect an IQ of ~78 or even lower. There also appear to have been actual IQ rises in the UK and Bermuda among Blacks and mulattos respectively.
These three cases actually expand on the Flynn Effect because the FE was previously simply showing rising IQ’s for all races, and while Black IQ’s were going up a lot, White IQ’s were going up by the same amount, so there was no closing of the B-W gap, and there was no actual rise in relative IQ.
In the Bahamas, there was a 15 point gain in relative IQ, that is, Blacks closed 15 pints of the B-W IQ gap.
In the UK, there was a 14 point relative IQ gain, and Blacks closed a 14 point B-W IQ gap.
In Bermuda, there was a 12 point gain in relative IQ, that is, Blacks closed a 12 point B-W IQ gap.
In the US, Dominica, and Kenya, we are still seeing Flynn rises among Blacks, but in the US and possibly in the other two places, there has nevertheless been no closing of the B-W gap.
While it benefits Blacks to get smarter, if Whites are rising at the same rate, some of the gains and all of the relative gains are wiped out.
After all, if there is a tiger chasing both of us, I don’t have to be faster than the tiger. I simply have to be faster than you.
With both Black and White IQ’s rising in tandem, the effect is simply one of an IQ arms race where neither side is gaining on the other while both become more heavily armed.
