When I search for spacing with word, I don't get the same number of hits. Also, your line numbers don't match with those I get, so are of no help. Anyways, I found a few more and corrected those.

Quote:Alternatively, perhaps the W-B d is just smaller now than it used to as claimed by some. Or not fully formed at these ages.

With regards to r (B/W d x B/W h^2), age and test type were major confounds; there weren't enough samples to control for these. The d-values averaged to 0.88 for the 6 non CNLSY samples. Age and test type were likely factors; birth year wasn't. Regarding Rowe and Cleveland's CNLSY sample, the d values were only 0.3 to 0.5, but this had more to do with the waves selected and the nature of the achievement tests used. Murray found no birth cohort effect for this sample.

To clarify, I added:

"Generally, the average H/W mean score difference (d-value) in these samples was of a similar size to that found nationally (0.7 versus 0.7), while the average B/W d-value was somewhat smaller (0.8 versus 1.0). The reduced magnitude of the B/W d-value from these samples was likely due to a participant age and test type effect....

Were a bio-ecological model correct, one might expect that d-values would positively correlate with heritability differences, such that when d-values were larger, the lower scoring population would show more depressed test heritabilities. Unfortunately, our samples do not allow us to robustly determine whether this is the case as they differ in participant age and test type, differences which would cofound any such analysis and which cannot be controlled for given the dearth of samples available."

Quote:I'm not aware of any studies of assortative mating by race. If the strength of this is different, it should change the amount of genetic variance within race.

I'm not either.
