In cognitive science and evolutionary psychology, Machiavellian Intelligence (Political Intelligence or Social Intelligence), is the capacity of an entity in successful political engagement with social groups. The term refers to Niccolo Machiavelli's The Prince (1513) and the hypothesis that the techniques which lead to certain kinds of political success within large social groups are also applicable within smaller groups, even within the family-unit. The term "everyday politics" was later introduced in reference to these various methods. These arguments are based on research by primatologists such as Nicholas Humphrey (1975).
Some theorists believe that autistic people lack Machiavellian intelligence. One hypothesis is that they lack a "theory of mind" which is necessary for both cooperation and deceit.
