Biology and Selection into Entrepreneurship—The Relevance of Prenatal Testosterone Exposure (2016, methodology): “Even though the validity of 2D:4D as marker for PTE is supported by a number of studies (e.g., Hönekopp & Watson, 2010; Lutchmaya et al., 2004; Manning, 2002; Manning et al., 1998; McIntyre, Cohn, & Ellison, 2006), multiple factors affect 2D:4D, such that 2D:4D does not perfectly reflect PTE (cf.…”
Chapter 21 - Household Finance: An Emerging Field∗ (2013, neutral): “Lower 2D:4D ratio seems to be associated with higher testosterone exposure and to have an organizing effect on the brain that shapes, in a permanent way, future individual behavior (Manning, 2002)).”
Physical Attractiveness in Adaptationist Perspective. (2015, background): “Longer fourth digits are also associated with prenatal testosterone, and when photocopied dorsal and ventral hand surfaces were presented to subjects, digit length was positively correlated with rated attractiveness and sexiness of male and female hands (Manning, 2002).”
Digit ratios (2D:4D) as predictors of risky decision making for both sexes (2011, background): “One of the increasingly studied markers of the organizational influence of testosterone is the 2D:4D ratio (the ratio of the length between the second and fourth fingers), which is considered a persistent marker of exposure to prenatal androgens (Manning 2002).”
The Science of Sex Appeal: An Evolutionary Perspective (2010, background): “People exposed to high levels of testosterone during prenatal life tend to have ring fingers that are longer than their index fingers (low 2D/4D), whereas exposure to high levels of estrogen has the opposite effect, producing high 2D/4D (Manning, 2002).”
The second to fourth digit ratio and variation in the androgen receptor gene (2003, neutral): “In addition, there is evidence that men with low Dr-l also have more masculinised scores for such things as WHR, running speed, and left-hand preference (Manning, 2002). This, perhaps surprising, observation may arise as a result of lateralised effects of prenatal sex steroids. Manning et al. (1998)”
Testosterone and domain-specific risk: Digit ratios (2D:4D and rel2) as predictors of recreational, financial, and social risk-taking behaviors (2011, neutral): “As a result, the second-tofourth digit ratio (2D:4D) has been used as a proxy of both the exposure and sensitivity to prenatal testosterone (Manning, 2002; Manning, Bundred, Newton, & Flanagan, 2003).”
Developmental basis of sexually dimorphic digit ratios (2011, methodology): “Variation of 2D:4D ratios is widely considered to reflect different prenatal androgen levels, although it also has been reported that estrogen levels correlate positively with 2D:4D ratios (2, 11, 18).”
2nd to 4th digit ratios, fetal testosterone and estradiol. (2004, background): “high verbal fluency [16] and high levels of emotional behaviour [17], are associated with high 2D:4D.”
Personality and biological markers of creativity (2005, background): “A new burst of research has focussed on the link between relative growth of finger bones (2D:4D ratio) and aspects of intelligence, both triggered during embryonic growth by testosterone (see e.g. Manning, 2002).”
Second-to-fourth digit ratio related to verbal and numerical intelligence and the big five (2005, neutral): “Manning, 2002).”
