He is a frequent media spokesman, and has written about the importance placed in hair over the centuries and the fact that baldness until recently was not recognised as a social or medical issue, despite the sometimes catastrophic impact it can have on confidence and mental well-being. He wrote: "Male pattern baldness (MPB), the main cause of hair loss, affects an estimated quarter of men by the age of 30 and two thirds by the age of 60. Until recently, the impact baldness might have on confidence and well-being was little understood or recognised by the medical profession at large."
Fertility and intelligence
In 1982, Daniel R. Vining, Jr. sought to address these issues in a large study on the fertility of over 10,000 individuals throughout the United States, who were then aged 25 to 34. The average fertility in his study was correlated at −0.86 with IQ for white women and −0.96 for black women. Vining argued that this indicated a drop in the genotypic average IQ of 1.6 points per generation for the white population, and 2.4 points per generation for the black population.
In considering these results along with those from earlier researchers, Vining wrote that "in periods of rising birth rates, persons with higher intelligence tend to have fertility equal to, if not exceeding, that of the population as a whole," but, "The recent decline in fertility thus seems to have restored the dysgenic trend observed for a comparable period of falling fertility between 1850 and 1940." To address the concern that the fertility of this sample could not be considered complete, Vining carried out a follow-up study for the same sample 18 years later, reporting the same, though slightly decreased, negative correlation between IQ and fertility.
