A friend asks:
1) Are there any twins separated at birth studies on gayness? There seem to be twins separated at birth studies for everything else.
I’m guessing that sample sizes would be pretty small. How many identical twins-separated-at-an-early-age examples are there in the scientific literature? Have they been increasing in number in this century?
2) When was the SAT first gender- or race-normed? I think they did it first for girls who could never get double-800s because of the math section, but I don’t know what year. I want to know the cut-off point for when I can trust someone’s SATs.
The big change that added about 80 points to Verbal SAT scores but only 10 points to Math SAT scores was in mid-1995. Before then, it was close to impossible to score 1600 on just one exam. Here’s a People Magazine profile of five of the nine guys who scored 1600 in 1985.
So before 1995 it was very very hard to get a 1600 because it was very hard to get an 800 on the Verbal. Did raising Verbal scores by fiat help girls or boys more?
Is there any study summarizing Score Inflation over the years on the SAT and ACT? It seems like tweaking to drive up scores is increasing in frequency, but it’s hard to get a straight story.
On the other hand, it doesn’t seem like the testing agencies have been able to do much to erase The Gaps, at least not without wrecking the predictive validities of their tests. So they seem to be trying to inflate everybody’s scores in the hope that that will keep the Warriors of Wokeness away.
3) I’d also like to know how many people in the country got a perfect 1600, broken down by gender, from 1970 to the present.
