Borderline Personality Organization predicts Machiavellian interpersonal tactics

Despite the phenomenological (e.g., manipulativeness) and dynamic (i.e., emotion dysregulation) analogies between Machiavellianism and Borderline Personality Organization (BPO), the relationship between these constructs has not yet been investigated. In our study, 225 non-clinical, non-student adults (130 females; 32.33 ± 5.42 years of age on average) completed measures of BPO and Machiavellianism. Results showed that Machiavellian personality traits were positively correlated with fear of fusion, diffuse identity, and use of primitive defenses. Machiavellianism, in general, and Machiavellian interpersonal tactics were predicted by fear of fusion and use of primitive defenses. Results are discussed from the perspective of Life History Theory.
