Prenatal testosterone exposure linked to Machiavellianism and psychopathy.

Higher prenatal testosterone exposure is linked to Machiavellianism and psychopathy, according to a new study. The research provides evidence that some aspects of the Dark Triad of personality are linked to markers of prenatal testosterone exposure. The Dark Triad refers to a set of three personality traits: Machiavellianism, narcissism, and psychopathy. The study found that even before birth, our personalities are already taking shape, shaped by factors like testosterone levels. The findings also have implications for understanding personality and its relationship to sex and hormones.
