To tie this thread in with another recent thread on power, let's just say that this is a case of a massively overpowered study with an N of 689,003 producing effect sizes like d=.001, 008, and .02. Predictably, the y-axis on the graphs showing these effects does not begin at 0.
In fact, some of the ethical justification for the study is on the basis of the fact that the effect sizes were so small. Which reminds me of this exchange in O Brother, Where Art Thou? Pete: You miserable little snake! You stole from my kin! Everett: Who was fixin' to betray us. Pete: You didn't know that at the time. Everett: So I borrowed it until I did know. Pete<http://www.imdb.com/name/nm0001806/?ref_=tt_trv_qu>: That don't make no sense! Everett: Pete, it's a fool that looks for logic in the chambers of the human heart.
