Male extraversion and mating effort linked to testosterone

This study of Senegalese men from the December 2010 issue of Personality and Individual Differences shows that extraversion predicts mating effort and that extraverted men have higher levels of testosterone. By contrast, other Big 5 personality traits (i.e., neuroticism, openness and agreeableness) are unrelated to mating effort and testosterone levels. It looks like the dominance component of extraversion--linked in other studies to testosterone--is crucial.

  2. Right. From the study:

    Concerning conscientiousness, however, more than 90% of data points were biased towards the highest value, probably due to strong cultural enforcement; therefore this dimension was not included in the analysis.

    And here I thought stoicism was the ultimate indicator of manliness.

  4. Stoicism is the opposite of high neuroticism (emotionally cool vs. labile). Extraversion is about how outgoing you are -- and the ancients were very social, especially the Stoics who wanted to recruit new members from the general public.

    I thought this was an HBD site. A study of Senagalese comes across the wire and people jump? Could it be that extroversion and mating effort and any relationship between the two differ between populations? Just maybe?

  6. You wrote "mating effort". [Which is measured how?]

    What about mating success?
