"Thus, high levels of testosterone are associated with willingness to incur greater risk in both sexes."
In my experience, this view has loose ties to ADHD, specifically regarding the hunter-farmer hypothesis: https://en.wikipedia.org/wiki/Hunter_vs._farmer_hypothesis
Doesn't say it in the article, but Hartmann's main book on ADHD discusses how he tested an African tribe for ADHD. 100% of those tested were "positive" for ADHD.
I believe we're looking at evolutionary aftereffects of generations of family-based societies where men hunt and women run the family.
I have also come to this conclusion though personal experience.
A well-intentioned person for whom I hold the utmost respect said I exhibited hallmark symptoms of ADHD. I realized the shoe really did fit, so I decided to get tested.
In the end, I was "diagnosed" with ADHD, allowing me access to a variety of drugs to "treat" it. They don't help. I have a stash of Adderall XR I don't use because it makes me feel...wrong. I've realized I need to change my approach to how I work. Systematic breaks to clear the mind helps tremendously. Coffee has a calming, stabilizing effect. Meditation of various types (Koru is an excellent system) has also helped understand my mind better to know when I'm getting off track.
I am fully convinced people "with" ADHD are supposed to be living as bold risk-takers because their bodies are literally wired for it. More men than women are wired like this, but both can "have" ADHD. Pencil-pushing desk jobs are not for these people, unless they're doing off-the-wall research and analysis.
If this is indeed true, why are we not seriously reconsidering this whole thing of dosing kids on very shaky grounds?
There are a couple of points in very early life, then not until puberty.
You could still point to the indirect effects of elevated T during infancy.
