Machiavellianism in psychology is described as a personality trait that involves manipulation and exploitation, and self-interest being considered at the expense of others. It is among the characteristics of the Dark Triad of personality, including narcissism and psychopathy. Individuals with high Machiavellianism tend to be tactical, and ready to employ deception to get their way. They are not always impulsive, and instead they are deliberate and pragmatic, placing more emphasis on power and control than morality. Indicatively, at work place, an employee with high Machiavellian qualities may impress others to influence them but subsequently use such influences to benefit him/herself.
It has been found that Machiavellianism has been associated with diminished empathy, diminished prosocial behavior, and increased interpersonal conflict, but in certain competitive contexts it can lead to short-term benefits. Psychologists research this trait in order to learn how it influences relationships, leadership and even ethical decision-making among other impacts that it has on organizational and social dynamics.
