“Are less able to forego the immediate pleasure of ice cream for the future positive of not being overweight and diabetic” (p31)Also, low-IQ people:
“Are likely to understand less about healthy eating and simply possess less knowledge of what constitutes healthy food or a reasonable portion” (p31)However, while there are borderline cases (e.g. foods misleadingly marketed as healthy), everyone knows that lots of cake is unhealthy. But resisting the temptation to eat another slice is often easier said than done. I therefore suspect willpower is a better predictor than IQ of weight.
“Extraverts simply enjoy everything positive more, and this includes tasty (and thus unhealthy) food” (p32).Both conscientiousness and extraversion are indeed associated with BMI (Bagenjuk et al 2019; Sutin et al 2011).
“We would also expect the more masculine-looking person to have higher levels of autism traits” (p34).This is based on Simon Baron-Cohen’s Extreme Male Brain Theory of Autism.
“The relationship between spatial ability and [circulating] testosterone levels is described by an inverted U-shaped curve… Spatial ability is lowest in those with the very lowest and the very highest testosterone levels, with the optimal testosterone level lying in the lower end of the normal male range” (Biology at Work: p115; see also The g Factor: p534)Dutton claims, “There is evidence that testosterone level in healthy males is positively associated with spatial ability” (p36). But the study he cites for this involved older men (Janowsky et al 1994). Since testosterone declines with age, this study is consistent with the relationship between testosterone and spatial ability described by Browne (see Moffat & Hampson 1996).
“Men who are high in testosterone… tend to be of shorter stature… High levels of testosterone at a relatively early age have been shown to reduce stature” (p34)Thus, eunuchs castrated before puberty are said to grow taller than other men.
“Hipsters with their Old Testament beards are showcasing their genetic quality… Beards are a clear advertisement of male health and status. They are a breeding ground for parasites” (p61).But why then have beards come into fashion only recently?
“[Beards] have been found to make men look more aggressive, of higher status, and older… in a context in which females tend to be attracted to slightly older men, with age tending to be associated with status in men” (p61)But why then, today, do most men prefer to look younger.
“A highly feminine face is attractive, in particular in terms of a short term relationship… [where] a healthy and fertile partner is all that is needed” (p43).In contrast, he concludes that for a long-term relationship a less feminine face may be desirable, since “being extremely feminine in terms of secondary sexual characteristics is associated with an r-strategy” and hence infidelity (p43).
“Exhibit… an autonomous, initiatory, appetitive sexuality which investigators have characterized as evidencing a high sex drive or libido” (The Evolution of Human Sexuality: p290)This would suggest masculine-looking women are more prone to infideltiy.
“[In ancestral environments] populations… so low in ethnocentrism as to espouse multiculturalism and reject religion would simply have died out… Therefore… the espousal of leftist dogmas would partly reflect mutant genes, just as the espousal of atheism does. This elevated mutational load… would be reflected in their bodies as well as their brains” (p76).But this seems unlikely, since atheism and liberalism are also associated with intelligence, probably an index of good genes.
“If the profile of someone’s fingers is smoother, more like a shovel, then it implies high testosterone. If, by contrast, the little finger is significantly smaller than the middle finger, which is highly prevalent among women, then it implies lower testosterone exposure” (p69).Actually, both the little finger and middle finger are irrelevant to 2D:4D ratio.
“[Since] Down Syndrome and Foetal Alcohol Syndrome are major disruptions of developmental pathways and… lead to very low intelligence and a very small nose… even minor disruptions would lead to slightly reduced intelligence and a slightly smaller nose” (p51-2).Indeed, foetal alcohol syndrome is itself a matter of degree.
“Let us be consistent. It is very common in psychology to find a correlation between, for example, a certain behaviour and accidents (or health) of 0.15 or 0.2 and thus argue that action should be taken based on the results. These sizes are considered large enough to be meaningful and even for policy to be changed” (p82)Using physical appearance to make assessments is particularly useful, Dutton observes, “in extreme situations when a quick decision must be made” (p80).
“Dear obese PhD applicants: if you didn’t have the willpower to stop eating carbs, you won’t have the willpower to do a dissertation #truth”According to Dutton, willpower is indeed correlated with obesity. But a PhD supervisor has access to more reliable information regarding a person’s personality and intelligence, in the form of their application and CV, than is discernible from physique. The outrage Miller’s tweet provoked was, then, not entirely unwarranted.
Consistent with this, Lewis (2012) exposed 20 men who were white, black, and East Asian to 300 Facebook photos of university students aged between 18 and 30 from these three races. He found that, among students at Cardiff University, men of all races found East Asian women the most physically attractive, black women the least physically attractive and whites intermediate. Conversely, when the experiment was repeated with 300 photos of men, the 20 women of these races found black men the most physically attractive, East Asian men the least, and whites intermediate. Lewis hypothesized that a significant reason was testosterone, as expressed in average levels of femininity and masculinity and in coloration.
