Intelligence: Is there a sex difference in IQ scores?
Paul Irwing and Richard Lynn
Arising from: S. Blinkhorn Nature 438, 31-32 (2005); Blinkhorn replies.
Abstract:

Steve Blinkhorn criticizes our study of samples of university students, in which we found that the average IQ of men is 4.6 points higher than that of women, as measured by the Progressive (or Raven’s) Matrices. He maintains that there is a negligible sex difference in adult intelligence. We believe that the principal error of Blinkhorn’s criticism is that he does not consider our result in the context of several other studies showing that adult males have an IQ advantage of around 4–6 IQ points.

  1. Regarding the finding of a sex difference in IQ scores, La Griffe, in his January article, derives, using an indirect, powerful, and quite elegant method, a figure for this which is comparable to the one published by Rushton et al:

    -

    “Adjusted parameter values yielded a male-female gap of 0.162 SD in g equivalent to 2.43 IQ points in favor of men, and a variance ratio (F/M) of 0.916.”

  2. Here we see an egalitarian academic almost apologising for his ‘unequal’ findings :

    Also, women are outnumbered 2 to 1 in Mensa ,
    of which my race-realist wife is a member.
