Differential response within the survey is again as bad.
The response rate for the survey as a whole was about 20% (265 of 1345), and below 8% (102) for every individual question on which data was published across three papers (on international differences, the Flynn effect, and controversial issues).
Respondents attributed the heritability of U.S. black-white differences in IQ 47% on average to genetic factors. On similar questions about cross-national differences, respondents on average attributed 20% of cognitive differences to genes. On the U.S. question, there were 86 responses, and on the others, there were between 46 and 64 responses.
Steve Sailer’s blog was rated highest for accuracy in reporting on intelligence research—by far, not even in the ballpark of sources that got more ratings (those sources being exactly every mainstream English-language publication that was asked about). It was rated by 26 respondents.
The underlying data isn’t available, but this is all consistent with the (known) existence of a contingent of ISIR conference attendees who are likely to follow Sailer’s blog and share strong, idiosyncratic views on specifically U.S. racial differences in intelligence. The survey is not a credible indicator of expert consensus.
(More cynically, this contingent has a history of going to lengths to make their work appear more mainstream than it is. Overrepresenting them was a predictable outcome of distributing this survey. Heiner Rindermann, the first author on these papers, can hardly have failed to consider that. Of course, what you make of that may hinge on how legitimate you think their work is to begin with. Presumably they would argue that the mainstream goes to lengths to make their work seem fringe.)
