Digit Ratio (2D
Same-sex attraction may be linked to low prenatal androgen (in men) and high prenatal androgen (in women). Digit ratio (2D:4D) is thought to be a negative correlate of prenatal androgen and right-left 2D:4D (Dr-l) to reflect lateralized differences in sensitivity to prenatal androgen. Lower 2D:4D has been reported for lesbians compared to heterosexuals, but links to high 2D:4D in gay men are less clear. The largest study thus far (the BBC Interne…
The effects of sex, nation, ethnicity, age and self-reported pubertal development on participant-measured right-left 2D
Digit ratio (2D:4D) – a proxy for prenatal sex steroids – shows sex, nationality and ethnic differences and is linked to pubertal onset. It is unclear whether right-left 2D:4D (Dr-l) also correlates with prenatal sex steroids, as evidence of these differences has been less conclusive. The present study examined the effects of sex, nation, ethnicity, age and self-reported pubertal development (i.e. the rate of physical development and age at menar…
Digit ratio (2D
Digit ratio – a putative measure of prenatal sex steroids – may be related to body mass index (BMI). However, reports of correlations between 2D:4D and BMI have yielded mixed results with some studies showing no relationship while others have reported positive associations in men or women only. This study considers associations between self-reported 2D:4D and BMI in a large online survey (i.e. the BBC Internet Study). At the individual level, the…
Number of friends and self-perception among Jamaican children
The role that physical attractiveness and fluctuating asymmetry (FA), a measure of developmental instability, play in self-perception and peer associations were explored in a well-studied cohort of Jamaican children using a novel research paradigm where subjects were already known to each other for extensive periods of time. The results showed that how attractive a child was perceived by others was significantly positively correlated with self-ra…

Parental Investment and Sexual Selection
There is a tendency among biologists studying social behavior to regard the adult sex ratio as an independent variable to which the species reacts with appropriate adaptations. D. Lack often interprets social behavior as an adaptation in part to an unbalanced (or balanced) sex ratio, and J. Verner has summarized other instances of this tendency. The only mechanism that will generate differential mortality independent of sexual differences clearly…
Self-deception facilitates interpersonal persuasion

Body symmetry and physical strength in human males
OBJECTIVES: Body symmetry and physical strength in males have been related to aspects of mate "quality"-women seem to prefer men who display both "good genes" (as indexed by high symmetry/developmental health) and fighting ability (as indexed by physical strength). Here we show that fluctuating asymmetry (FA) of the body and physical strength are negatively correlated. METHODS: Body FA (from 12 paired traits) and handgrip strength (HGS; a measure…
Deceit and self-deception
In Deceit and Self Deception Robert Trivers, whose work has been acclaimed by figures such as Richard Dawkins and Steven Pinker, looks at how and why we so often deceive ourselves. We lie to ourselves every day: about how well we drive, how much we're enjoying ourselves - even how good looking we are. In this ground-breaking book, Robert examines not only how we self-deceive, but also why, taking fascinating examples from aviation disasters, con …
A Longitudinal Study of Digit Ratio (2D
A Longitudinal Study of Digit Ratio (2D:4D) and Its Relationships with Adult Running Speed in Jamaicans Robert Trivers, Renato Hopp, and John Manning Dear Editor, We write to point out that digit ratio may be a useful childhood biomarker for endurance running in adults. We have considered this question in a cohort of Jamaican children who have been studied from 1996 to the present day (Trivers et al. 1999). Digit ratio (2D:4D; the relative length…
A Longitudinal Study of Digit Ratio (2D)
The evolution and psychology of self-deception
In this article we argue that self-deception evolved to facilitate interpersonal deception by allowing people to avoid the cues to conscious deception that might reveal deceptive intent. Self-deception has two additional advantages: It eliminates the costly cognitive load that is typically associated with deceiving, and it can minimize retribution if the deception is discovered. Beyond its role in specific acts of deception, self-deceptive self-e…

Natural Selection and Social Theory
Robert Trivers is one of the leading figures pioneering the field of sociobiology. For Natural Selection and Social Theory, he has selected eleven of his most influential papers, including several classic papers from the early 1970s on the evolution of reciprocal altruism, parent-offspring conflicts and asymmetry in sexual selection, which helped to establish the centrality of sociobiology, as well as some of his later work on deceit in signallin…

Ear asymmetry and left-side cradling
Parent-Offspring Conflict
When parent-offspring relations in sexually reproducing species are viewed from the standpoint of the offspring as well as the parent, conflict is seen to be an expected feature of such relations. In particular, parent and offspring are expected to disagree over how long the period of parental investment should last, over the amount of parental investment that should be given, and over the altruistic and egoistic tendencies of the offspring as th…

The Evolution of Reciprocal Altruism
A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. The model shows how selection can operate against the cheater (non-reciprocator) in the system. Three instances of altruistic behavior are discussed, the evolution of which the model can explain: (1) behavior involved in cleaning symbioses; (2) warning cries in birds; and (3) human reciprocal altruism. Regarding human reciprocal altruism,…
