michael woodley and co. have discovered a bit of modern research on reaction times very (but not exactly) like galton’s late nineteenth century research in london which they feel supports their claims that western iqs have gone down by 14.1 points since the victorian era.
it’s a VERY interesting study, but i’m still not 100% convinced. if the study and its findings are replicated, i might be! (^_^)
i left a comment over there @dr. james thompson’s blog, but, as of the writing of this post, it hadn’t been approved, so i reproduce below.
look forward to more research into this question! neat (and important!) stuff!
“cool study! thanks for drawing it to everyone’s attention, and … yes, i agree … the design of this study seems to be much closer to galton’s original study, so yeah … lots of little red flags should be raised! (^_^)
“personally, i’m still not 100% convinced, though, because i dislike the fact that we have to use *indirect* means to check that the samples are similar — for example, having to rely on eckstein and feist to tell us who, *in general* british museum goers are. i wish wilkinson and allison would’ve just told us *directly* who their participants were! and as for the ethnicity question — that the subjects were white is not enough. they need to be white *brits*. if, for instance, they had too many southern italians or southern spaniards or even irish folks in their study, etc., etc., that might again have dragged down (or up, rather) the scores … *somewhat*.
“(wrt to question of paying for admission, we’ve got indirect evidence for that here as well. a quick email to wilkinson or allison should be able to answer that question. keep in mind, too, that presumably only *some* of galton’s subjects paid a museum entrance fee since on three or four days a week [don’t recall which it was] admission was free to the museum.)
“nevertheless, these are some very interesting results. what would be great, of course, would be to see this study *repeated* and the results *replicated*. if i were to design such a study, i’d make sure that it was in every way possible identical to galton’s, that way there’d be no questions about the sampling, etc. it’d also be cool to test the same individuals’ reaction times on *both* an old, galton-type machine AND a modern one to see exactly how the machines compare.
“in lieu of such a study (or better yet, in conjunction with it), i really think you guys should delve into that 1984-85 health & lifestyle study from the u.k., because they recorded ethnicity and, presumably, ses, so you could get at a sample like galton’s that way. of course, then you’d be left with a modern machine in that instance. i leave the reliability of the machines discussions up to other folks. (and the correlation of rts to iq discussion, too.)
“thanks again, guys!”
