IQ is bad science anyway. It only measures what a person knows in relation to other people of the same age. A child can have a very high IQ at age 6 and at age 40 not score as well. Did the person become dumber?? No, the rest of the 40 year olds caught up and now the avereage is different. http://www.danielgoleman.info/blog/2007/03/13/the-trouble-with-iq/ "The relation of IQ to exceptional performance is rather weak in many domains…For scientists, engineers, and medical doctors…the correlations between ability measures and occupational success are only around 0.2, accounting for only 4% of the variance (Baird, 1985). More generally, prediction of occupational success from psychometric tests has not been very successful. In a review of more than one hundred studies, Ghiselli (1966) found the average correlation between success-on-the-job measurements and aptitude-test scores to be 0.19. Aptitude tests can predict performance immediately after training with an average correlation of 0.3, but the correlation between performance after training and final performance on the job is only about 0.2 (Ghiselli, 1966). Reviews of subsequent research have reported very similar correlation estimates. When corrections were made for the restriction of range of these samples and for unreliability of performance measures, Hunter and Hunter (1984) found that only cognitive ability emerged as a useful predictor with an average adjusted correlation of 0.5 with early job performance. However, a recent review (Hulin, Henry and Noon, 1990) has shown that with increased experience on the job the predictive validities of ability tests for performance decrease over time by an average correlation of 0.6. This implies that ability tests can predict early performance on a job, whereas final performance is poorly predicted." Most people would perfer that their child grow up to be well-adjusted and successful within their chosen career path. i would be more impressed with the breastmilk to IQ study if the children studied were raised in identical circumstances, for example perhaps a single set of parents raising their children in identical way with only the breastmilk being the difference. The problem with "studies" of this kind is that someone sets out to 'prove' the exact result they are seeking. If you want to find the face of Jesus in a tortilla, all you have to do is flip through enough tortillas and presto! you'll find one!
