Testosterone-related abstracts from AAPA 2016

Facial width-to-height ratio (fWHR) is not associated with pubertal testosterone
Several researchers have proposed that facial width-to-height ratio (fWHR) is a sexually dimorphic signal that develops under the influence of pubertal testosterone (T); however, this hypothesis is currently under supported. Here we examine the association between fWHR and T during the period of the life span when facial growth is canalized--adolescence. To do so, we examine the association between T, known T-derived traits (i.e. strength and voice pitch), and craniofacial measurements in a sample of adolescent Tsimane males. If fWHR variation derives from pubertal T’s influence on craniofacial growth, several predictions can be made: 1) fWHR should increase with age as T increases, 2) fWHR should reflect adolescent T (rather than adult T per se), 3) fWHR should exhibit a growth spurt in parallel with T, 4) fWHR and T should correlate after controlling for potential confounds, and 5) fWHR should show a strong relationship to other T-derived traits. These effects were not observed. We also examined three additional facial masculinity ratios: facial width/lower face height, cheekbone prominence, and facial width/full face height. In contrast to fWHR, each of the three additional measures exhibit a strong age-related pattern of change and are associated with both T and T-dependent traits. In summary, our results challenge the status of fWHR as a sexually-selected signal of pubertal T and T-linked traits.
The relationship between social status, body size, and salivary hormone levels among Garisakang forager-horticulturalist men of lowland Papua New Guinea
Social hierarchy is a robust phenomenon that exists within all human societies. Over the past several decades, a growing body of evidence from industrialized Western populations has suggested that social status is closely related to individual measures of stress, health, and many other fitness-related traits. Data regarding such relationships, however, remain rare among small-scale subsistence societies, preventing a clear understanding of the importance of social position for fitness cross-culturally. Here we contribute to this area of research by exploring the relationship between adult male social status, BMI, and levels of salivary testosterone and diurnal cortisol among Garisakang small-scale forager-horticulturalists of lowland Papua New Guinea (N = 32). Three measures of individual social status – Respect, Dominance and Prosociality – were extracted from principal components analysis of photo-rank data for locally valued male traits (e.g., sociability, hunting ability, community influence). Preliminary results from multiple regression models controlling for age suggest complex relationships between social status, body size, and salivary hormone levels among the Garisakang. Male Dominance is positively related to BMI (p < 0.05) but not with salivary hormone measures, while greater male Respect is associated with reduced salivary cortisol (p = 0.06) but not testosterone or BMI. Prosociality, conversely, is not significantly related to any evaluated measure. We discuss the evolutionary implications of our findings, with a focus on future directions for investigating the biocultural interface of health in this population.
Men’s reproductive ecology and diminished hormonal regulation of skeletal muscle phenotype: An analysis of between- and within-individual variation among rural Polish men
Human life history is characterized by several distinctive features—sexual division of labor, prolonged care of altricial young, multiple dependents of different ages, and male provisioning. Testosterone has been suggested to mediate a trade-off between men’s reproduction and survival, through the regulation of sexually dimorphic musculature. This hypothesis predicts a relationship between testosterone and musculature in which mating effort, elevated testosterone, and dimorphic musculature covary positively. Testosterone is also posited to mediate a trade-off between mating and parenting effort, and accordingly, investing fathers show decreased testosterone production. Because men use their musculature not only in mating competition but also to support work demands, an important component of parenting effort, a relatively fixed relationship between testosterone and muscularity would seem maladaptive. We hypothesize that men’s parenting effort, specifically provisioning and subsistence activities, becomes a primary determinant of muscularity. Life history, anthropometric, and hormonal data were collected from 122 rural Polish men (at the Mogielica Human Ecology Study Site) during the summer harvest and for 103 of these participants in the winter. We found that fatherhood jointly predicted heavier workload and decreased testosterone, but positively predicted muscle mass and strength measures. Furthermore, within-individuals, men experienced intensified workload and suppressed testosterone during summer, along with a concomitant increase in muscularity and strength. These findings provide preliminary support for our model, termed the ‘Paternal Provisioning Hypothesis’. Between and within individuals, men’s provisioning and subsistence activities were robust predictors of muscular development and performance, whereas their testosterone levels had no appreciable effect on skeletal muscle phenotype.
Testosterone, musculature, and development in Kanyawara chimpanzees and Tsimane forager-horticulturalists
Considerable evidence suggests that the steroid hormone testosterone mediates major life-history trade-offs in primates, promoting mating effort at the expense of parenting effort or survival. In many species, chronic shifts in testosterone production over the life course correlate with investment in male-male competition. Chimpanzees and humans represent interesting test cases, because although closely related, they maintain divergent mating systems. Chimpanzee males do not invest in pair bonds or paternal care. Consequently, across the lifespan, their testosterone levels are expected to track changes in (1) behavioral investment in dominance striving, and (2) investment in sexually dimorphic musculature employed in male-male competition. Humans, by contrast, are expected to show weaker associations between testosterone and musculature, because the latter is important not only for male competition, but for men’s work provisioning wives and children. We assayed >7000 chimpanzee and >3350 Tsimane urine samples for testosterone, creatinine, and specific gravity, in the same laboratory using the same assay methods. Male chimpanzees showed peak acceleration in testosterone increase at age 6, peak velocity at age 10, and peak deceleration at age 14, reaching adult levels by 15-16, when they began to challenge other adult males. Adult levels of testosterone were achieved 3 years later than in captivity, likely reflecting energetic constraints in the wild. Indirect measures of muscle mass followed a similar pattern, and were highly correlated with testosterone. As predicted, Tsimane men exhibited a weaker correlation, with testosterone accounting for half as much variance in the muscle mass measure as in the chimpanzee sample.
Dads and cads? Male reproductive success, androgen profiles, and male-infant social bonds in wild mountain gorillas (Gorilla beringei beringei)
Male reproductive strategies are often reduced to a ‘dad versus cad’ dichotomy. When paternity certainty is high and mating opportunities scarce, theory predicts high levels of paternal investment; if paternity certainty is low and/or access to mating opportunities plentiful, male parenting is expected to be scarce. However, conflict between mating and parenting behavior is not equally strong across ecologies and social structures. Wild mountain gorillas (Gorilla beringei) have variable paternity certainty and a morphology suggestive of intense male contest competition. Despite this, relationships between males and infants are an important component of group structure, likely because males protect infants from infanticide and predation. Using data from gorilla groups monitored by the Dian Fossey Gorilla Fund’s Karisoke Research Center, we evaluated 1) the relationship between male-infant social bond strength and males’ reproductive success, and 2) the relationship between male-infant social bonds and males’ fecal androgen metabolite levels. Higher testosterone levels are generally correlated with increased aggression and mating activity, which are typically considered incompatible with parenting behavior. After controlling for male age and rank, males who had the strongest social bonds with infants were also the males with the highest reproductive success. There was no relationship between strength of male-infant social bonds and fecal androgen metabolite levels. Results demonstrate that reductive descriptions of male reproductive strategies may obscure important connections between mating and parenting effort, and highlight the need for additional data on the relationship between androgen activity, mating, and parenting in multimale/multifemale social systems.

Rightists fatter than leftists?

Commenter Mugabe holds up a "map showing that obesity rates for whites is highest in the red states" as evidence American conservatives are more likely to be obese that US leftists.

Similar notions have circulated among the clickbait consumers of the left for years (based on the same sort of inadequate state-level data). In 2010, Razib, looking at individual-level GSS data found:

I don’t see a notable different obetween liberals and conservatives. The only exception might be that liberals are more well represented among those who are below average in weight than those who are considerably above average, but the samples are small enough than I don’t trust that to be anything more than measurement error.
A survey from neuropolitics.org similarly found:
The above graph shows some interesting trends. First, the Very Liberal males reported the highest percent in the relatively trim 0-5 pounds range, (46%), and the highest rate, among males, in the obese 41+ range (16.8%). The regular Liberal males were second in the 0-5 range, at (38.3%). The Conservative and Very Conservative males had the lowest rates in the 0-5 range, at (29.6 and 34.9%).

Conversely, the Very Conservative females reported the highest rate in 0-5 range (38.2%). The regular Conservative females were next at (31.2%). The Very Liberal and Liberal females had the lowest rates in the 0-5 range, at (26 and 31%). They also had the highest rates in the obese 41+ range (17.7 and 19.4%). [. . .]

According to our survey respondents, the Liberal males are thinner than the Conservative males, and the Conservative females are thinner than the Liberal females. However, this is self-reported, not controlled for age, and not clinically confirmed. So for now, the hypothesis that political-gender cohorts have different average Body Mass Indexes is still very speculative.

The finding that leftist males are disproportionately likely to be very skinny or very fat is in line with my own impressions. Unattractive and sex atypical people (effeminate males, masculine females) are drawn more strongly to leftism. Sex typical, conventionally attractive people are more likely to be conservative. Larger (non-obese) and more masculine males are more comfortable with undisguised assertion of self- and group interest (probably because weighted across evolutionary time they're the ones, at the top of status hierarchies, who could get away with it).

Garry Trudeau: weak, sensitive boy traumatized by prep school, not a product of "old money liberalism"

"Old money liberalism" is a myth. The idea that upper class "WASPs" as a group lean left is a product of 1950s "conservative" political correctness and various combinations of aspirational leftist self-deception and manipulation.

Steve Sailer writes:

For example, consider Garry Trudeau. He was a scion of old money liberal Protestant good blood good bone folks (his mother went to Miss Porter’s School, for example)
1. Let's not exaggerate the wealth or social standing of Trudeau's family. While I don't doubt they easily fell within the top 5% in both respects, thousands of people of Trudeau's generation were born into richer families with more impressive ancestors, and most of these people did not become obnoxious leftists.

Trudeau's father and paternal ancestors going back several generations were doctors. His mother's father was a sales manager and Republican politician. Certainly respectable and likely prosperous people, but I'd say they belonged to the multigenerational upper middle class rather than the upper class.

2. It would have been more helpful for this narrative if Garry Trudeau's parents were actually liberal. Trudeau's mother belonged to a Continuing Anglican church. Trudeau's parents were Republicans. They did not encourage their son's faggotry. A fan lazily (or wishfully) attempts to frame Trudeau's leftism in terms of the make-believe construct of "old money liberalism":

Members of Trudeau's more recent family tree were not rabidly Republican, but their politics, perhaps because of their privileged social status, leaned to the right. As an educated, civically engaged family, they saw themselves as belonging, nevertheless, to a tradition of liberal egalitarianism. In his satire he has made the dissonance of these competing ideologies a major theme, continually returning to the ironies and hypocrisies of individuals and a society built on such conflicted ideas. In addition, having been raised at the intersection of the ethics of aristocratic gentility and liberal idealism, Trudeau seems to have adopted a sense of noblesse oblige that has fueled both his selfless devotion to promoting social justice through satire, as well as his supreme confidence in his worldview, his business ethics, and his position as social chronicler.

One may also speculate that Trudeau's populist indignation at corrupt authority, nepotism, and old-boy networks is rooted in a need to exorcise a sense of lingering guilt at having such fortunate opportunities. It has even been speculated that the depth of his intense loathing for the Bush family comes from his need to differentiate his own privileged, WASPy persona--one that is tempered by self-criticism and a championing of social underdogs--from that of other Ivy Leaguers who, from his perspective, have seemingly used their background and connections to increase their own wealth and power. For example, those strips which mock the elder Bush for his participation in the closed Skull and Bones society at Yale (the university attended by Trudeau as well) reflect a vehemence and particularity that belies his deep-seated, especially personal dislike for this other type of New England family. (At the same time, one could argue that the Bush family's adoption of swaggering, folksy, Texan personas was an effort to distance themselves from the type of liberal New England elitism they saw in families like Trudeau's; Bush indicated as much in 1988, when he charged that Trudeau only spoke "for a bunch of Brie-tasting, Chardonnay-sipping elitists" [Alter 67].)

But no support whatsoever is offered for claims that the family professed "a tradition of liberal egalitarianism" (nor have I been able to find evidence for this elsewhere), and his parents do not seem to have been active in politics.

(As for the assumed connection to New England, only one of Trudeau's great-grandparents was born in Vermont; the other seven and proceeding generations were born in the mid-Atlantic. In total, no more than 1/4 of Trudeau's ancestry traces back to New England; 1/8 of Trudeau's ancestry is French, his great, great-grandfather having been an evidently incompetent Confederate officer and doctor from New Orleans; the remainder of his ancestry came by way of the mid-Atlantic and includes Dutch and German.)

The facts actually presented by this author paint a picture not of a self-assured aristocrat driven by a sense of noblesse oblige and carrying on a tradition of "liberal idealism" picked up from his family, but of a sensitive bitch who couldn't hang with other members of his class, who because of this developed a resentment of winners, and who imbibed his liberalism from popular culture.

By Trudeau's own description, he was an awkward teenager. Physically weak, athletically slow, pigeon-toed, and small for his age, he did not fit into the popular crowd. About his time at St. Paul's prep school in New Hampshire, he says, "I was not the class clown. In fact, I was pretty shy. . . . [It was a] tortured time for me [because] I was the second or third smallest in my class" (Alter 64). As a result of being ostracized from the elite cliques at school, Trudeau's inner, imaginative life was given ample time and space to develop. He found solace in art--an interest that did not help his social life; a classmate recalls that the prep school was "an unbelievably bad climate to be an artist," and as a result, "Garry took a lot of grief" ("Doonesbury: Drawing and Quartering" 60).

The traumas of his teen years--including seeing his parents divorce--gave him ulcers and probably contributed to his career-long sympathy for people in minority or underdog positions in society. He has little nostalgia for this awkward period in his life; for example, he stated in an interview in 1986 that "Adolescence is, I think, an unpleasant time of life no matter where you spend it and with whom you spend it. I didn't like being a teenager. I didn't like teenagers when I was one. And I still don't like them. It's a very selfish time of life" (Grove D15).

As Trudeau entered into his young adult years--the point at which he was expected to follow his father's lead in becoming a physician--his interest in art and theater put him at odds with his extended family. One can see how Trudeau's creative and sensitive personality did not mesh his father's worldview, a philosophy that can best be summarized in the maxim he repeated often to his son: "Life is not something to be enjoyed, so just get on with it" (Weingarten W14). In some way the disconnect between Trudeau's aspirations and his family's expectations was typical of many family conflicts in the late 1960s when staid lifestyles of the older generation clashed with the newly bohemian, countercultural ethics of their children. Trudeau was not a rebellious kid in any radical sense, but his affinity for the arts seemed to place him within the general parameters of this dissenting youth culture. Trudeau jokes that during his teen years his grandmother "would plead with my parents to send me to Outward Bound, because she had read in Life that the counselors were very good at reaching troubled teens" (Trudeau, Flashbacks 90). [. . .]

In light of Trudeau's adult dedication to following politics with a wonk-like intensity, it is interesting to note that, although he had vague countercultural leanings as a youth, he did not have a deep understanding of politics or any strong convictions about particular parties or candidates during his formative years. Here he describes this teenage detachment:

I wasn't particularly politically attuned growing up. There wasn't much debate at our dinner table. My parents were Republicans, so the GOP was my team, and Ike was our genial manager. In '60, I was too young to really respond to JFK's charisma as intuitively as I was repelled by Nixon's sleaziness, and in 1964, I was so disengaged that I actually designed placards for both parties at my high school. Later I came to admire Robert Kennedy and Martin Luther King, but more as pop figures than as visionaries who changed the world. Vietnam was the wake-up call. That's when I really started paying attention, and by then heroes were in scarce supply. Besides, who needed role models? We had the certainty of youth. (Bates 62)

[. . .] This gradual success of the strip also won for Trudeau some grudging praise from his family. His father offered him barbed congratulations, saying, "You're lucky you were born when you were. In my day you'd have been a loser" (Trudeau, Flashbacks 16). Similarly, his mother quipped after hearing he had won a Pulitzer Prize in 1975, "I'm perfectly thrilled and delighted. I've kept my fingers crossed for fear he might end up in jail" (Trudeau, "Investigative Cartooning" C1).

Size Matters: How Height Affects the Health, Happiness, and Success of Boys--and the Men They Become
Wherever boys play games, as on the playing fields of nature, where predation and aggression have shaped animal behavior for tens of millions of years, sheer size makes a difference. You won't find that fact in many textbooks, but it may be the single most important lesson of unsupervised schoolboy existence.

The way those feelings of beleaguerment, insecurity, and behavioral adaptation live on in an adult psychology has been insightfully captured by the cartoonist Garry Trudeau, the creator of Doonesbury. In a lovely 1996 essay called "My Inner Shrimp," Trudeau admits that "for the rest of my days, I shall be a recovering short person" with "the soul of a shrimp." Trudeau, unlike some of us, benefited from a delayed but explosive growth spurt that propelled his final height to over six feet. But it's the feelings he experienced at age fourteen, when he was the third-smallest kid in his high school class, that still perfuse his adult soul. Trudeau sometimes pondered going to a high school reunion to show off all those postpubertal inches. But the Little Man Inside nixed the idea.

"Adolescent hierarchies," he writes, "have a way of enduring; I'm sure I am still recalled as the Midget I myself have never really left behind."

We do have some preliminary evidence that Conservatives and Liberals vary, on average, in their testosterone-estrogen ratios, with Conservatives males higher on the testosterone side, and Conservative females higher on the estrogen side. This means that the Liberal females and males are closer to each other in their testosterone-estrogen ratios, and the Conservatives further apart.
Formidability and the logic of human anger
Individuals with enhanced abilities to inflict costs (e.g., stronger individuals) or to confer benefits (e.g., attractive individuals) have a better bargaining position in conflicts; hence, it was predicted that such individuals will be more prone to anger, prevail more in conflicts of interest, and consider themselves entitled to better treatment. These predictions were confirmed. Consistent with an evolutionary analysis, the effect of strength on anger was greater for men and the effect of attractiveness on anger was greater for women. Also as predicted, stronger men had a greater history of fighting than weaker men, and more strongly endorsed the efficacy of force to resolve conflicts—both in interpersonal and international conflicts.
Facial Structure May Predict Endorsement of Racial Prejudice

Studies have shown that facial width-to-height ratio (fWHR) is associated with testosterone-related behaviors, which some researchers have linked with aggression. But psychological scientist Eric Hehman of Dartmouth College and colleagues at the University of Delaware speculated that these behaviors may have more to do with social dominance than outright aggression.

[. . .] “Racial prejudice is such a sensitive issue and there are societal pressures to appear nonprejudiced. More dominant individuals might care less about appearing prejudiced, or exercise less self-regulation with regard to reporting those prejudices, should they exist,” says Hehman, who conducted the research as a graduate student at the University of Delaware.

The researchers asked male participants about their willingness to express racially prejudiced beliefs and about the pressure they feel to adhere to societal norms. The results revealed that men who have higher fWHR (determined from photos of their faces) are more likely to express racist remarks and are less concerned about how others perceive those remarks.

Alex Shoumatoff on St. Paul's School
For the past 150 years St. Paul’s School, the “exclusive” (as it is invariably called) boarding school in Concord, New Hampshire, has been the Eton of America’s upper crust. Or perhaps it is its Hogwarts, as Harry Potter’s fictional academy is called, providing the country with many of its most accomplished wizards—not just at making money, although that is what its graduates have tended to do, but in practically every endeavor. Its main constituency has traditionally been the conservative old Wasp families of New York, Boston, and Philadelphia—the plutocracy that has been running the country for generations. But this is changing. Since the first black student was admitted—in my class, which graduated in 1964—the school’s admissions policy has been progressively more meritocratic. The “natural aristocracy,” based on virtue and talent, to use Thomas Jefferson’s distinction, has been displacing the “artificial aristocracy,” based on wealth and birth. Every year there are fewer “legacies,” fewer fourth- or fifth-generation Paulies, among the 533 students, who now come from 37 states and 21 countries.

Despite its reputation for being a breeder of staunch, old-line Republicans, St. Paul’s has also turned out a distinguished roster of liberals, including the cartoonist Garry Trudeau and Senator John Kerry. Kerry was in the class of ’62, two years ahead of me, and even then he seemed to be plotting his run for the presidency. [. . .]

The fourth element of the St. Paul’s calamity had been incubating for years: the allegations that, from the late 1940s through the early 90s, dozens of the school’s masters (as the teachers were known until women joined the faculty, in 1972), including several revered ones, had sexually molested students. [. . .] But boarding schools attract sexually conflicted adults. [. . .]

The faculty was also at odds with the rector and the board. Partly it was because the teachers were liberals, and the trustees were for the most part stodgy conservatives “who have not crossed the postmodern line into the world with the rest of us,” as one faculty member put it. And partly it was a class issue: the trustees acted as if the teachers were underlings, when in fact it is the teachers who dedicate their lives and careers to fulfilling the school’s mission.

Bodily symmetry: origins and lifecourse associations with cognition, personality, and status

A 2012 PhD thesis (pdf):
Symmetry – measured as the size asymmetry of a group of symmetrical body traits such as ear height or elbow circumference – has often been used as an index of the capacity to develop normally despite stress and correlates with a wide range of outcomes including intelligence, health and aspects of behaviour. [. . .] The present work advances the existing empirical literature in six separate domains. It also improves upon past methodology by using novel methods of digital measurement of asymmetry as well as for the first time digitally measuring endogenous asymmetry as indexed by the bones and linking bone asymmetry to intelligence. The research was conducted on four samples. [. . .] Firstly, a sample of elderly participants from the Lothian Birth Cohort 1921 (LBC1921, n = 216) tested around ages 11, 79, 83, and 87. Secondly, the Science Festival Sample (SFS), a group of children recruited at a public science event aged between 4 and 15 (n = 856). Thirdly, a group of Orkney residents aged 18 to 86 (the ORCADES, n = 1200). Fourthly the Berlin Sample (BS), a group of Berlin residents (n = 207) between 20 and 30 years old. In the LBC 1921, men with poorer socioeconomic status in childhood had higher facial asymmetry in old age ( = -.25, p = .03). While investigating issues related to asymmetry in the same sample it was found that relatively more severe digit curvature – a minor physical anomaly – was associated with relatively greater cognitive decline ( = -.19, p = .02). Within the SFS asymmetry decreased across human childhood ( = -.16, p = .01), and more asymmetrical children exhibited slower choice reaction times ( = .0.17, p = .002). In the ORCADES sample, the more asymmetrical participants (as indexed by bone asymmetry) were less intelligent ( = -.24, p = .01). In the Berlin Sample and the LBC 1921 no consistent associations were found between personality traits and asymmetry. Collectively, these findings suggest symmetry functions as a measure of overall well-being as the trend is for higher asymmetry to be associated with a relatively poorer score on a variety of outcome measures. The findings considerably expand the number of existing studies in these empirical areas and in several cases – particularly asymmetry’s association with socioeconomic status in the elderly and reaction times among children – represent the first work on those areas. The present work confirms the finding that asymmetry is linked to adverse outcomes. However, the underlying mechanisms by which symmetry is linked to such outcomes remain underexplored and require clarification.

Men With Wider Faces Are More Generous to Their In-Group When Out-Group Competition Is Salient

Face Structure Predicts Cooperation: Men With Wider Faces Are More Generous to Their In-Group When Out-Group Competition Is Salient (abstract):

Male facial width-to-height ratio appears to correlate with antisocial tendencies, such as aggression, exploitation, cheating, and deception. We present evidence that male facial width-to-height ratio is also associated with a stereotypically male prosocial tendency: to increase cooperation with other in-group members during intergroup competition. We found that men who had wider faces, compared with men who had narrower faces, showed more self-sacrificing cooperation to help their group members when there was competition with another group. We propose that this finding makes sense given the evolutionary functions of social helpfulness and aggression.

Eye color and perceived dominance

This study ("Eye color predicts but does not directly influence perceived dominance in men") has gotten some attention, having been reported as if the result were universally applicable.

In fact, there's no evidence it applies outside the sampled population (students in Prague). What the researchers actually seem to have "discovered" is the existence of population structure in the Czech Republic that manifests in different frequencies of morphological types among lightly- and heavily-pigmented inhabitants.

The composite photographs from the paper show a somewhat foetalized, Slavic-looking "Alpine" blue-eyed morph and a "Dinaric" brown-eyed morph. Or as the authors put it:
In contrast with blue-eyed males, brown-eyed males have statistically broader and rather massive chins, broader (laterally prolonged) mouths, larger noses, and eyes that are closer together with larger eyebrows. In contrast, blue-eyed males show smaller and sharper chins, mouths that are laterally narrower, noses smaller, and a greater span between the eyes.
According to Coon, "Alpine" and "Dinaric" types differ in frequency between regions of what of what is now the Czech Republic:
While Alpines and Norics are commonest in Bohemia, there is a strong concentration of Dinarics in Moravia, especially among the miners, who seem to form a special group with both racial and occupational peculiarities.
To their credit, the authors advance "genetic linkage" as one potential explanation for their results (noting that this hypothesis could be tested by repeating the experiment in different populations), though this seems to be their least favorite of the three possible explanations they lay out. Unfortunately for them, it's also the most likely to be correct.

More correlations from Sheldon (1942)

Sheldon finds IQ positively related to aesthetic quality (the t component), grip strength, aesthetic intelligence ("the degree to which an individual reveals fine discernment and sensitive appreciation of his environment"), and sexuality ("manifest sexuality, or the relative importance and prominence of the sexual impulse in the individual's history"), and unrelated to masculinity/femininity and central strength ("back and leg lift", essentially deadlift I assume).
The positive correlation between aesthetic quality and IQ seems consistent with the suggestion that "an over-arching ‘fitness factor’ (an index of general genetic quality that predicts survival and reproductive success)" (pdf) contributes to both health and IQ. Sheldon believed t-component ratings reflected underlying genetic quality. Other reported physical correlates of IQ include more linear facial features (continue reading).

Some notes on Sheldon and correlations between physique and personality

A pdf version of William H. Sheldon's 1942 book Varieties of temperament: a psychology of constitutional differences can be downloaded here. A summary of Sheldon's claims and some later work:
Sheldon (1942) claimed to have found strong correlations between somatotype and human behavior.

He posited three fundamental dimensions of temperament, each associated with a component of physique;
  1. Visceratonia (associated with endomorphy) is characterized by lassitude, slow reaction to stimuli, and love of eating and physical comfort.
  2. Somatotonia (associated with mesomorphy) is characterized by assertiveness, risk taking, aggressiveness, and indifference to pain.
  3. Cerebrotonia (associated with ectomorphy) is characterized by physical and emotional restraint, fast reaction to stimuli, and social inhibition (Sheldon, 1942).
Table 1 shows the correlations between temperament and somatotype found by Sheldon (1942).

Table 1. Correlations between temperament and somatotype reported by Sheldon (p. 400, 1942)
Endomorphy Mesomorphy Ectomorphy
Viscerotonia .79 -.23 -.40
Somatotonia -.29 .82 -.53
Cerebrotonia -.32 -.58 .83
Note. All coefficients are significant at p < .01. N = 200.

However, these results were strongly criticized on methodological grounds. Sheldon’s early method of somatotyping, used in the 1942 study, involved a degree of subjective judgment (Carter and Heath, 1990; Cortés and Gatti, 1972; Parnell, 1958) and the ratings of temperament were made by the same researcher (Sheldon) who somatotyped the subjects. Sheldon fully acknowledged this latter point; [. . .]

Nevertheless, constitutional psychology can not be so easily dismissed. For example, there is now a large literature on the relationship between somatotype and a variety of health conditions, including hypertension and heart disease (Singh, 2007). Both Child (1950) and Cortés and Gatti (1965) tried to replicate Sheldon’s psychological findings using more objective somatotyping procedures and self-report measures of temperament. These results are shown in Tables 2 and 3.

Table 2. Correlations between temperament and somatotype reported by Child (p. 447, 1950)

Somatotonia .22*
Cerebrotonia .34***
Note. *p < .05, **p < .01, ***p < .001. N = 114. Other values not reported.

While the effect sizes were lower than those found by Sheldon, the pattern of correlations in these studies is essentially the same. There is now a substantial body of research showing weak to moderate correlations between somatotype and such variables as occupational interest (Deabler, Hartl, and Willis, 1975), academic performance (Parnell, 1958), temperament type (Peterson, Liivamagi, and Koskel, 2006), and susceptibility to hypnosis (Edmonston, 1977). Perhaps the most studied behavioral correlate of somatotype is the relationship between criminal behavior and mesomorphy (Cortés and Gatti, 1972; Glueck and Glueck, 1956). In a review of the research, Ellis and Walsh (2000) note that “to date, all studies have reported significant tendencies for delinquents and criminals to be more mesomorphic than persons in general” (p. 278).

John Derbyshire mentions a 1951 Life magazine article on Sheldon's work.
On the basis of his work up to now, many workers in the psychiatric field and in the allied sciences of sociology and anthropology are convinced that Dr. Sheldon has done what Hippocrates tried to do 2,500 years ago: he has shown that character and physique are closely related, and that the first, like the second, is to a considerable extent a product of heredity.

[Robert Coughlan. What Manner of Morph Are You? In old debate on what makes temperament a new school of "constitutional psychiatry" gives heredity equal place with environment. LIFE Jun 25, 1951.]
A fan of his work is mortified by Sheldon's political views:
Sheldon in The Varieties of Delinquent Youth ranted about the endomorphic-mesomorphic mothers of the delinquents, and how America had become mongrelized from its original New England Anglo-Saxon origins. But just how much of a racist was Sheldon? Here we can look at the account by John Sample, in "A Closer Look at William H. Sheldon." It certainly looks like Sheldon had become prey to all sorts of fearful and hostile fantasies.
From the aforementioned essay by John Sample:
Far from a coolly objective social theorist, Sheldon, vituperatively anti-Semitic, favored northern Europeans, particularly Anglo-Saxons, as his preferred racial groups.

At the end of our visit, Sheldon said I could look forward to doing "great things." I think he may have said this because I was a reasonably intelligent, clean-cut Wasp! [. . .] He sent me on my way with a copy of American Nazi Lincoln Rockwell’s biography… Those visits ended my personal contact with William H. Sheldon.
Sheldon's origins:
William Herbert Sheldon was born in Pawtuxet, Rhode Island, on November 19, 1898. His parents, William Herbert and Mary Abby Greene, were related to old New England families like the Carders and Remingtons. And his father had been well off until a partner in the family firm ran off with the money. William and Mary had lost their first two daughters to diphtheria and then had three more children: Israel in 1889, Kate in 1891, and finally William seven years later. Sheldon's father had been able to keep the family homestead, which dated from around 1740, and supported his family by working as a jeweler in nearby Providence.
More:
William Herbert Sheldon was born in Warwick, Rhode Island, to an old New England family; his father bred poultry and dogs competitively. Sheldon’s early familiarity with the idea of breeding better species, and his sense of the importance of his own Anglo-Saxon pedigree, fed into his lifelong advocacy of eugenics, the program for breeding better humans that inspired his morphological research. Through his father’s tutelage, Sheldon came to recognize what he later termed a t or thoroughbred factor in the human constitution, the quality of appearing aesthetically pleasing.

Physical condition of the Jews (1904)

From a New York Times article reporting on "an address delivered before the annual convention of the American Federation of Zionists" by Dr. Maurice Fishberg:
Throughout their history, said the speaker, the Jews had always considered the mind as of prime importance, and had developed it at the expense of their bodies. He continued:

"We all remember with what disdain the average Eastern European Jew looks upon anything which may tend to develop his muscular system. From the study of physicians and anthropologists we find that the Jews in Eastern Europe are short of stature; in some countries, like Galicia and Poland, they are only 5 feet 3 3/4 inches in height. In countries where their economic and social conditions are better, they are about one inch taller, but it is a matter of fact that they never reach the height of their non-Jewish neighbors.

"The average circumference of the chest of the Jews in Eastern Europe is about 32 to 34 inches, and is less than half their body height. As you probably know, the girth of the chest in a healthy man usually exceeds half his stature. [. . .]

"It is remarkable that while the stature of the Jews born in the United States is much superior to that of the foreign Jews, this is not true of the girth of the chest. [. . .]

"In order to assure a muscular Judaism you must encourage physical culture among the younger generation of American Jews.

Hrdlicka: A new Uncle Sam is in the making (1927)

Anthropologist Ales Hrdlicka on the "Uncle Sam" type:
We do not know who created the effigy of "Uncle Sam." The name itself, as is well known, dates from 1812 or 1813, and is assumed to have been simply a play on the letters "U. S." It was apparently first applied to a well-known Government servant. But the graphic representation of the "Uncle Sam" type appears later. It is somewhat provincial. It was never quite adopted by the Farther South, and it is not quite at home in the West. Its essential characteristics are a spare but sinewy frame, good but not very tall stature and a thin, shrewd but kind face, with eyes full of humor. The whole picture embodies picturesque conservatism, shrewd politics and, above all, unbounded patriotism.

Such a physical type belongs primarily to the Yankee territory. It does not agree with the prevailing types in the large cities of the country, in the North Central States, in parts of the South, in the pioneer West, Southwest and Northwest, nor with those in Alaska and our possessions. In all these regions it is the newer American type that is emerging.
Hrdlicka observes:
given time, aggregates of any groups and any number of groups of people, particularly if all belong to one and the same fundamental race will fuse and tend to develop a new resultant, new prevalent type, characteristic of that particular nationality. [. . .] America, too, may develop a prevailing type of its own.
Based on Hrdlicka's studies of "Old Americans":
it may be seen that the ideal "Uncle Sam" type was not far from the true one. A little taller stature, a bit less hooked nose, perhaps a trace shorter arms, and the rest fits nicely.

But this type over a large part of the country tends to be superseded by another, newer type. If the old American families could remain without further admixture for several more centuries, the type would undoubtedly be further crystallized and fixed; but there is not much hope that this may be accomplished. Instead of that, there is developing the newer American type, which has already been mentioned. [. . .]

The Neo-American type will be in all probability, on the average, tall, more sanguine and somewhat less spare than the old. It will remain an intermediary white type in pigmentation, head form and other aspects. It will show for a long time a wider range of individual and local variation in all respects. And it may well be expected to be a wholesome and effective type [. . .]

"Cousin William," then, will be tall, well nourished, with a good-sized, well-filled head, though more or less bald, and with an oval, also well-filled, intelligent but frank, jovial, "enjoy-and-let-enjoy," beardless face, and smiling, mixed-light pair of eyes, fond always of a good story, a thoroughly good sport, without hypocrisy or malice, and ready for anything big or ingenious or highly profitable or for politics, at any time. A fine, big shrewd but generous young or old boy, in general.
Czech immigrant Hrdlicka assures the reader:
The future of the older American stock need cause no concern. [. . .] None of these newcomers is physically so different from the older stock that the admixture with them could be regarded as of possible biological danger.
To close, here's the inflammatory opinion of Georges Vacher de Lapouge on the physical type of the Indo-Europeans:
As regards physical type, however, the image evoked by the name Aryan differs according to the author that one reads. For Mortillet, Topinard, or Drumont, the Aryan is an averred brachycephalic, resembling the chestnut peddler on our streets or the typical peasant of Piedmont, Auvergene, or Savoy. If the author is Ammon, Penka, or Wilser, the image is that of the typical globe-trotter from England or the "Uncle Sam" of the Yankees--lank-bodied, dolichocephalic, leptoprosopic, usually blond, adventurous, and aggressive. In my view, both these types were represented among the Aryans, but the dominant classes among them, the builders of the Aryan civilization, were of the type of "Uncle Sam," or, to use the terminology most suitable from the anthropological point of view, were of the race H. Europaeus.

Kimbo hype: a case study in negrophilia

An addendum to the previous post. Indra writes: In personal experience, I have also noticed that these negrophiles have no athletic history. White athletes, especially from combat-related sports like wrestling or football, quickly realize that you cannot judge a book by its cover, and that blacks with visually impressive muscularity are often NOT that powerful or effective in competition.

The Kimbo Slice story offers a particularly glaring example of this phenomenon.

In terms of external appearance, Kimbo Slice is undoubtedly in the 99th percentile of scary-looking negritude. Using Guy White logic it's obvious he's the greatest fighter of all time. With no hint of irony, (middle-aged, Jewish nerd) Mencius Moldbug describes Kimbo as "built to win".

Unfortunately for the logic of Guy White and Mencius Moldbug, the Kimbo hype train had already been repeatedly derailed by the time Mencius hopped aboard (continue reading).

"New" Shakespeare likeness

The Washington Post has a long article on the Cobbe portrait:
Just two images of Shakespeare are considered authentic by scholars, and both were done after the playwright died. [. . .] Both depictions are so unintelligent-looking that scholars blame them for instigating the Author Controversy, which is not really a controversy so much as a campaign by conspiracy-minded amateurs to prove that someone more visually appealing wrote the plays. The thinking goes that the "peculiar dough-faced man" in the Droeshout, as Stephen Greenblatt of Harvard University calls him, is too stolid to have written such soaring words. Someone else must have, preferably someone good-looking. As scholar Marjorie Garber writes, "We'd rather he not look like an egghead."

The Author Controversy persists despite considerable documentary evidence. We have the man from Stratford's pay stubs for performing at court, his certificate of occupancy for the Globe Theatre, and his will, in which he left memorial rings to some London actors. Funny he would do that if he was just a country burgher who didn't write the plays.

Still, it would help to have a decent picture of the man in his prime to keep the conspiracy theorists at bay. [. . .]

Ending No. 1: It's him. Someone discovers proof. [. . .] In which case our view of Shakespeare must shift. He is no bourgeois pudge but rather neck-deep in romantic and political intrigue, until he is forced back to the humdrum of Stratford only grudgingly, by some disgrace. [. . .]

"Sometimes people say, 'Well, does it matter what people looked like?'" Wells says. "Well, of course it matters. It's why we have portrait galleries. It's why we want to know what Shelley and Keats looked like -- and sometimes they look as we would like them to look."

"Anti-Semites" getting worse at identifying Jews?

So claim these unbiased researchers:
Anti-Semitism and Identification of Jewish Group Membership from Photographs
Susan A Andrzejewski, Judith A Hall, Elizabeth R Salib. Journal of Nonverbal Behavior. New York: Mar 2009. Vol. 33, Iss. 1; pg. 47, 12 pgs
Abstract (Summary)

Early literature found that holding more anti-Semitic attitudes positively predicted ability to discern whether a photograph was of a Jewish or non-Jewish person. This contradicts the well established finding that interpersonal sensitivity is generally associated with healthy psychological characteristics. In five new, previously unpublished studies we found that this relation was negative, such that more prejudiced individuals were now less accurate than less prejudiced individuals at a similar task, consistent with the general finding. A meta-analysis of all the studies showed that time was a significant moderator of the relation. Possible reasons for the temporal change are discussed. [PUBLICATION ABSTRACT]

Why?
We can speculate about other mechanisms that might have produced the positive relations in the earlier studies. In an earlier era, far from being associated with social deviance or maladjustment, the possession of anti-Semitic attitudes was respectable. At prestigious universities, anti-Semitism was openly espoused by many members of the student body, students’ families, faculty, and administration (Karabel 2005). Indeed, prejudice against minorities was previously seen as being rooted in normal processes (Dovidio 2001), as the expression of the ‘‘natural’’ superiority of some groups over others.

Today, however, outgroup prejudice is not considered socially acceptable and, indeed, is seen in many segments of society (perhaps especially in college students) as representing a kind of social deviance or pathology. Therefore, because being prejudiced is now seen as abnormal rather than normal, the characteristics of the high prejudiced person and the low prejudiced person may have changed over time. The person who espouses high levels of outgroup prejudice today is likely to possess a range of problematic psychological characteristics that are inconsistent with the development of interpersonal sensitivity, whereas we can speculate that the high prejudiced person of the past used to possess more welladjusted psychological characteristics. Today, highly prejudiced individuals readily endorse cultural stereotypes (Kawakami et al. 1998), and they feel angry about being constrained by other people’s standards for them (Devine et al. 1991). More prejudiced individuals are consistently classified as being less psychologically healthy than those who are less prejudiced (Hightower 1997; Pettigrew 1981). Thus, prejudice in an earlier era might not have been as psychologically unhealthy as it is today.5

A second line of speculation stems from the functional value of having skill in identifying Jewish faces. As noted earlier, the motive to ‘‘spot the enemy’’ proposed by Allport and Kramer (1946) might have made more sense at an earlier time than it does today. In an era when the normal social order was assumed to have wealthy White Christians (indeed, Protestants) at the top, the motive to bar Jews from attaining power and privilege (or dating one’s sister, etc.) would have been well served by a finely honed ability to identify them. Today, however, it is all but impossible for the prejudiced person to exclude Jews from advancement or to avoid their presence in neighborhoods, educational institutions, and workplaces. Therefore the potential value of being able to ‘‘spot the enemy’’ has been greatly reduced. Further undermining the adaptive value of being able to ‘‘spot the enemy’’ is the fact that the enemy is no longer very difficult to spot. In the earlier era of more overt discrimination, many Jews tried to conceal their minority group membership. In such a climate, the prejudiced person would need to develop an acute ability to use expressive or physiognomic cues to pick out members of the stigmatized group. Today, in contrast, it is highly unlikely that Jewish individuals try to hide their group membership, meaning that the prejudiced person has much less need to develop sensitivity to subtle cues indicating Jewish group membership.

Another possibility not mentioned: the inclusion of non-white subjects renders comparisons with earlier studies meaningless. Participants in the new studies are only around 67-74% "Caucasian". I imagine the small negative correlation could simply be an artifact of non-white subjects being both more willing to give "anti-Semitic" answers and worse at distinguishing between Jews and Northern Europeans. Regardless:
Accuracy on the Jewish identification task was significantly above chance in all five studies (chance = 50%, or 25 items correct; Table 1). Accuracy was slightly but non-significantly lower in Studies 3–5 where there was a mixture of ethnicities among the non-Jewish faces as opposed to only Anglo non-Jewish faces. [Note: Studies 3-5 also included a higher proportion of non-white participants.]

Body type and perceived personality

The perceived associations of the participants in this study are reminiscent of--though not identical to--the associations argued for by Sheldon.
Through the use of many photographs and measurements of nude figures (mainly Ivy League students), Sheldon assigned people into three categories of body types in the 1940s: endomorphic, mesomorphic, and ectomorphic. He also assigned personality traits to the body types as well. Endomorphics had fat, soft, and round body types, and their personality was described as relaxed, fond of eating, and sociable. Mesomorphics were muscular, rectangular, strong, and personality-wise were filled with energy, courage, and assertive tendencies. Ectomorphics were thin, long, fragile, as well as brainy, artistic, and introverted; they would think about life, rather than consuming it or acting on it.
This study looks at perceptions of six different body forms (three different body types, with and without abdominal obesity):
Physical characters were associated with the appropriate body forms as expected. The physical traits strong, rough and tough and physically aggressive were associated with the muscular non-obese [M−] figure. Lethargic was associated with F+. Disease prone was significantly associated with L− [lean, without central obesity] on the one hand and F+ [feminine, with central obesity] on the other indicating that people negatively associate both the extremes with health. The trait swift was also strongly associated with L−. The traits that are not obviously physical were also strongly associated with certain body forms. Brave, conscious about looks, influential, dominating, status conscious, modern and confident were associated with M−; physical risk avoider, money minded, political, rich, stupid, selfish and greedy were associated most strongly with F+; friendly, intelligent, methodical, business risk avoider, successful, loving, kind, and honest were associated with F− [feminine without central obesity]; and L− was the commonest choice for swift, physical risk avoider, talkative and the trait depressed was associated with L+ [table 1].

Obesity as a Perceived Social Signal

Manasee Mankar et al.

Fat accumulation has been classically considered as a means of energy storage. Obese people are theorized as metabolically ‘thrifty’, saving energy during times of food abundance. However, recent research has highlighted many neuro-behavioral and social aspects of obesity, with a suggestion that obesity, abdominal obesity in particular, may have evolved as a social signal. We tested here whether body proportions, and abdominal obesity in particular, are perceived as signals revealing personality traits. Faceless drawings of three male body forms namely lean, muscular and feminine, each with and without abdominal obesity were shown in a randomized order to a group of 222 respondents. A list of 30 different adjectives or short descriptions of personality traits was given to each respondent and they were asked to allocate the most appropriate figure to each of them independently. The traits included those directly related to physique, those related to nature, attitude and moral character and also those related to social status. For 29 out of the 30 adjectives people consistently attributed specific body forms. Based on common choices, the 30 traits could be clustered into distinct ‘personalities’ which were strongly associated with particular body forms. A centrally obese figure was perceived as “lethargic, greedy, political, money-minded, selfish and rich”. The results show that body proportions are perceived to reflect personality traits and this raises the possibility that in addition to energy storage, social selection may have played some role in shaping the biology of obesity.

Jews tend to look Jewish

This apparently shocks some people [1]:
Fifty-two Jewish subjects and 60 non-Jewish subjects were presented with a disguised ethnic identification task. Sixty systematically grouped portraits were used. Religion sortings were administered among sortings by intelligence, age and likability. Subjects were also questioned concerning the cues they used. Jewish pictures were comparatively accurately identified by all subjects, and tended to be more accurately identified by Jewish subjects than by non-Jews. Pictures classified as Jewish also tended to be sorted as bright, especially by Jewish subjects. There was less evidence of ethnocentricity in other sortings, apparently in part because of relatively stereotyped classifications by brightness and liability. These tow evaluative dimensions were also highly correlated. Jewish pictures tended to be judged through the use of physiognomic cues, whereas Catholicism was frequently inferred from other categories (nationality); Protestantism tended to be a residual category.

[. . .]

Accuracy of Identification. All three groups of subjects (Jews, Catholics and Protestants) identified the Jewish pictures as Jewish at better than chance frequency. Combining all the subjects, 16 of the 20 Jewish pictures were correctly identified (see criterion above for correct identification). Using the binomial expansion, it was found that the probability of correctly identifying this many or more pictures by chance was less than .006. Thirteen of the 20 Jewish pictures were correctly identified by more than half of the subjects.
The level of accuracy achieved by the classifiers in this study, using only small photographs, suggests a lower boundary that can only be improved upon by anyone with above-average perceptiveness interacting with actual people.

I actually agree with the commenter at Dienekes' that the fraction of (Ashkenazi) American Jews with blatant, stereotypically-Jewish features is around 1/2. But I strongly disagree with the implicit claim that the other half are visually indistinguishable as Jews.

The four most frequently cited sets of cues were dark hair, an oversized nose, general "Jewish" facial characteristics, and similarity in appearance of the depicted persons to Jews in the subjects' acquaintance. Non-Jewish subjects seemed more prone than Jewish subjects to refer to specific features (hair color being the most salient example), whereas Jews seemed more inclined to cite global characteristics. [A superscript for the following footnote appears here: "Rommetveit concludes from a series of studies of social perception that "intuitive" global judgments (as opposed to those based on specific traits) are characteristic of accurate social perceivers. (See Ragnar Rommetveit, Selectivity, Intuition and Halo Effects in Social Perception, Oslo, Norway: Oslo University Press, 1960.)] Dark complexion constitutes an exception to this rule, since it was cited by proportionately more of the Jewish subjects.
Those who hilariously cite such blond Jews as Barbra Streisand and Gene Wilder as proof "Jews are white" should see the second point I've emphasized in the above text (on global judgments vs. specific traits). Two more of RM's "Northern European" Jews, pre-dye and nose jobs:

Incidentally, with data of the sort presumably to be generated by the "Jewish HapMap Project", it ought to be easy enough to quantify European admixture in Ashkenazi Jews. It may even be possible to directly test the proposition that AJs were selected for lighter pigmentation while remaining predominantly non-European in ancestry.
