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

#9
I made two more minor corrections plus those below.

"Dalliard's name is misspelled."

Fixed.

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

Citation at end of paragraph.

"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."

Fixed.

"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."

h^2 typically means narrow heritability, while broad heritability is H^2.

"This overlaps with the beginning of the Introduction. Rewrite."

Fixed.

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

Added colon. “Meta-analysis: method


"Desegregated sounds like you are saying they live in racially segregated communities as in Apartheid times."

Fixed.

"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?"

Added above: "Regarding the computation of ACE estimates, following ordinary practice, we standardized the values such that the total variance added up to 1.00 and no A, C, or E values were negative."


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

rewrote as: "g-scores were derived from scores on Digit Span Forward and Backward, PIAT-M, PIAT-RR, PIAT-RC, and PPVT tests taken at age 11. The results are shown in the supplementary file. The genetic variances were 0.61 for Whites, 0.55 for Blacks, and 0.60 for Hispanics. The fact that the g scores are based on multiple tests should make the results reasonably reliable."

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

Fixed.

"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?"

Discussed above.

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

Extended = sibs + cousins. The cousins only shows very high h^2.
