No, Machiavellianism is not a clinical diagnosis and is not listed in mental disorder registries (such as the DSM-5). It is a psychological construct describing personality traits and social behavioral strategies. However, it is part of the "Dark Triad" along with narcissism and psychopathy.
Research indicates that moderate Machiavellianism can contribute to success in competitive environments, such as business or politics, where negotiation skills are vital. However, in the long run, excessively high scores can hinder the formation of trust within a team.
This test is a precise digital adaptation of the original questionnaire by Christie and Geis. The result provides a reliable assessment of your Machiavellian tendencies, though it can be influenced by your current mood and your level of honesty when answering complex ethical questions.
