Population differences in androgen levels: A test of the Differential K theory

Demographic, economic, and genetic factors related to national differences in ethnocentric attitudes

“…The following variables are measures of testosterone and are included to assess the role LH strategy (see Dutton et al, 2016). (14) CAG repeats on the AR Gene (CAG).…”

“…(15) Androgenic hair. Data for the percentage of the male population that has midphalangeal hair as a proxy for androgenic hair as a measure of androgen levels given in Dutton et al (2016). (16) DRD4-repeats (DRD4).…”

“…This includes the need for future-oriented alliances and strong bonds. Testosterone has been shown to be linked to a fast LH strategy (Dutton, Van der Linden, & Lynn, 2016).…”

National‐level Indicators of Androgens are Related to the Global Distribution of Scientific Productivity and Science Nobel Prizes

“…Yet, although some smaller studies with specific samples compared various national groups (e.g., Chin et al., ; Santner et al., ), there seems to be remarkable lack of cross‐cultural studies with national representative samples that have directly compared androgen levels. Similar to previous studies (e.g., Dutton et al., ; Westlund et al., ), we therefore used a set of indirect indicators of the level of, or sensitivity to, androgens. They were selected on the basis of two criteria.…”

“…A number of reviews and meta‐analyses have compiled data on the proportion of people having mid‐phalangeal hair in various countries (Hindley & Damon, ; Westlund et al., ), based on which Dutton et al. () reported estimates of the proportion of the population with mid‐phalangeal hair (MPH) for 124 countries. No estimates were present for South‐American, and Southern and central African countries.…”
