[OBG] Genetic and Environmental Determinants of IQ in Black, White, and Hispanic Amer

#6
sp = spacing problem

6:
sp

7:
Dalliard's name is misspelled.

18:22
Needs a cite for claims. Pick one of the recent review articles. Last sentence should probably get "in adults".

32:
You mean "genetic" (broad). E includes error, which is worth mentioning because authors rarely correct for test unreliability so their results are underestimates as pointed out by Jensen in his '69 paper.

33:
h2 isnt the same as a2. a2 refers to additive genetic factors. h2 may or may not include more depending on whether it is broad or narrow. Narrow h2 is the same as a2.

40:46
This overlaps with the beginning of the Introduction. Rewrite.

56:
sp

57:
Odd phrasing. “Meta-analytic method” maybe? Or just “Method”?

60:
sp. There are so many more of these. Just search for “[space][space]” in the text editor to find them.

83:84
Rewords. Desegregated sounds like you are saying they live in racially segregated communities as in Apartheid times.

Tables have visual problems.

100:
Odd phrasing. “Results” or “Meta-analytic results” or something.

169:
I don't understand the results in Table 7. There are clearly non-zero values in Unstandardized col. E, but they are exactly 0 in Standardized. Explain?

283:
Where is “the first table”? I can't find a table with results for the g factor.

Can you conduct MCV analyses to see whether the g-loading of the subtest correlates with the h2 of it as claimed by among others Jensen (1998)? I note that the A for the g factor is higher than that reported in the Table 8, which indicates that it is the g factor that drives the h2, not the remaining variance.

Added. From looking the later tables, there are only 5 subtests with low heterogeneity, so MCV is probably not worth doing.

291:
Both Hart et al studies (2010, 2013) are missing from the reference list. You should check for more missing references.

It seems to me that research based on extended relations would be theoretically superior, not less robust. I could not check the Hart reference to see if some justification was given in that for this claim. Explain?

303:
You should conduct a test to see if this difference is reliable. Fluke perhaps? It goes against all standard theory that h2 should be lower for whites.

338:
Actually, the three way pattern of results is exactly reverse. In sibs: W>H>B. In extended, B>H>W. Very strange. Analytic error? I note that it is found using both methods of dealing with age from looking at Table 12.

353:
Sampling error does not seem a plausible candidate. All sample sizes are in the thousands. From looking at Table 12, the smallest sample is N=1112. Very large for a BG study.

367:
The extended model, does that also use siblings, or only cousin and further away data? Perhaps try estimates based only on e.g. cousins.
