It has also been found that the observed relationships among the dark triad, and among the dark triad and the Big Five, are strongly driven by individual differences in genes. Compared to biological factors, the influence of environmental factors seem to be more subtle and account for less—yet still significant—variation in individual differences as related to the development of dark triad traits.
Machiavellianism is the most likely dark triad trait to be influenced by experience. At the very least, this notion about the modifiability of Machiavellianism does make some sense insofar as that the less variance there is attributable to genetic factors, the more variance there must be attributable to other factors, and “other” factors have traditionally been synopsized as environmental or experiential in nature.
