Machiavellian hypothesis

Machiavellian hypothesis

the hypothesis that the evolution of intelligence, especially in its social aspects, was largely dependent on behavior characterized by a desire and striving for power. According to the hypothesis, individuals who are more Machiavellian in their behavior are more likely to be successful in adaptation and thus more likely to spread their genes to future generations. [Niccolò Machiavelli (1469–1527), Italian political theorist]
