(2005) The gender similarities hypothesis. American Psychologist, 60(6), 581-592. <A HREF="http://www.apa.org/journals/releases/amp606581.pdf" REL="nofollow">Full text.</A><BR/><BR/><I>...the greater male variability hypothesis was originally proposed more than a century ago, and it survives today (Feingold, 1992; Hedges & Friedman, 1993). In the 1800s, this hypothesis was proposed to explain why there were more male than female geniuses and, at the same time, more males among the mentally retarded. Statistically, the combination of a small average difference favoring males and a larger standard deviation for males, for some trait such as mathematics performance, could lead to a lopsided gender ratio favoring males in the upper tail of the distribution reflecting exceptional talent. The statistic used to investigate this question is the variance ratio (VR), the ratio of the male variance to the female variance. Empirical investigations of the VR have found values of 1.00 -1.08 for vocabulary (Hedges & Nowell, 1995), 1.05-1.25 for mathematics performance (Hedges & Nowell), and 0.87- 1.04 for self-esteem (Kling et al., 1999). Therefore, it appears that whether males or females are more variable depends on the domain under consideration. Moreover, most VR estimates are close to 1.00, indicating similar variances for males and females. Nonetheless, this issue of possible gender differences in variability merits continued investigation.</I><BR/><BR/>2) Spelke, E. S. (2005). Sex differences in intrinsic aptitude for mathematics and science: A critical review. American Psychologist, 60, 950-958. <A HREF="http://www.wjh.harvard.edu/~lds/pdfs/spelke2005.pdf" REL="nofollow">Full text.</A><BR/><BR/><I>If the genetic contribution were strong, however, then males should predominate at the upper tail of performance in all countries and at all times, and the male-female ratio should be of comparable size across different samples. Contrary to this prediction, the preponderance of high-scoring males is far smaller in some countries (e.g., Deary et al., 2003) and altogether absent in others (Feingold, 1994). Moreover, the preponderance of boys with high scores on the SAT-M has declined substantially in U.S. samples. In one sample of students selected for high talent, it declined from 10.7:1 in the 1980s to 2.8:1 in the 1990s (Goldstein & Stocking, 1994). The performance of boys and girls on standardized tests likely reflects a complex mix of social, cultural, and biological factors.</I>Theohttps://www.blogger.com/profile/03344294173628793721noreply@blogger.comtag:blogger.com,1999:blog-264226589944705290.post-52979939544308813812007-09-15T00:22:00.000-07:002007-09-15T00:22:00.000-07:00Hi.

The effects of inheritance of wealth may well swamp the effects of difference in distribution of IQ.<BR/><BR/>As for gender, in many systems of inheritance, women can’t inherit; in some, women are not permitted to own or to control assets (this was the case in France until 1946). In such cases too, the effects of cultural constraints will overwhelm the effects of difference in distribution of IQ.ha’pennyhttps://www.blogger.com/profile/14473695098449453347noreply@blogger.comtag:blogger.com,1999:blog-264226589944705290.post-7141912082970417072007-09-08T11:08:00.000-07:002007-09-08T11:08:00.000-07:00It would be interesting to see if the same applies...It would be interesting to see if the same applies to human races.Anonymoushttps://www.blogger.com/profile/10764009141275700054noreply@blogger.comtag:blogger.com,1999:blog-264226589944705290.post-23256099103405978232007-09-08T03:44:00.000-07:002007-09-08T03:44:00.000-07:00So it would be interesting to study the distributi...So it would be interesting to study the distribution of log(income) for the two genders and compare results. Wonder if it has alread been done? Or if there is raw data available so you could do the analysis yourself?Anonymousnoreply@blogger.com
