what kanazawa said was: “The physical attractiveness of each Add Health respondent is measured three times by three different interviewers over seven years.”

the “three times” refers to the first three waves in the add health survey.

in the first wave, 12,105 adolescents were interviewed for 1-2 hours during a 9 month period.

if all the interviews were 1.5 hours, interviewing 12,105 subjects would amount to over 2270 eight-hour days.

there’s only ca. 21.6 working days per month on average x 9 months x 3 interviewers = 583 eight hour days. but you’d need 12 interviewers to cover 2270 eight-hour days.

and that’s just in the first wave. wave ii saw 15,000 students interviewed; wave iii, 15,170.

also, the fieldworkers used typically work only a 20-25 hour week, so there’s at least twice the number of interviewers required than i’ve guessed at here.

in any case, n≠3.

there is still, however, the problem of the race and gender and age of the interviewers. that would be essential to know (along with the number!).

Oh, I should so leave it at that…

I do like your list you put up, always some interesting items in it.

(Oh, er, and the Suicide Rates link committed suicide.)
