Introduction:
The objective is to evaluate the presence of Machiavellian intelligence with the MACH-IV Scale in antisocial patients versus community controls.
Material And Methods:
Categorical diagnosis and dimensional evaluation program according to IPDE were obtained from 26 controls from the community and 40 patients from a methadone program. Both groups were evaluated on cooperation with TCI and on Machiavellian intelligence with MACH-IV.
Results:
Higher figures in MACH-IV Global Score, Tactics subscale (to manipulate others), Visions subscale (interpretations on Machiavellian behavior of others) were found in the 20 antisocial patients compared with the 26 community controls achieving statistical significance. No statistical differences were found for Morality subscale scores (abstract morality) between groups. Dimensional evaluation of antisocial disorder according to IPDE shows statistically significant positive correlations for Tactics subscale, Visions subscale and Global Score of MACH-IV scale, but no statistically significant correlation was found for Morality subscale. There is a statistically significant negative correlation between MACH-IV Tactics subscale and TIC altruism subscale.
Conclusions:
Antisocial patients have the same level of abstract moral attitudes as controls but are prone to use Machiavellian intelligence to interpret the actions of others, rationalize their own conduct and manipulate the behavior of others to get a benefit. These data support the hypothesis that many of the features of the antisocial syndrome may be explained by an abnormal development of an innate predisposition to be dominant in social relationships.
Insights
Antisocial patients exhibit higher Machiavellian intelligence, particularly in manipulation and interpretation, compared to community controls. Their abstract moral attitudes remain similar, suggesting Machiavellian traits drive their social interactions.
Area of Science:
- Psychology
- Social Psychology
- Clinical Psychology
Context:
- Machiavellian intelligence is a personality construct characterized by manipulativeness, cynicism, and a pragmatic approach to morality.
- Antisocial personality disorder (ASPD) is a mental health condition characterized by a pervasive pattern of disregard for and violation of the rights of others.
Purpose:
- To evaluate the presence and characteristics of Machiavellian intelligence in individuals with antisocial tendencies compared to community controls.
- To investigate the relationship between Machiavellian intelligence and antisocial personality disorder traits.
Summary:
- Antisocial patients scored significantly higher on the MACH-IV Global Score and its subscales for Tactics and Visions, indicating greater manipulative tendencies and interpretation of others' behavior through a Machiavellian lens.
- No significant differences were found in the Morality subscale, suggesting abstract moral reasoning is comparable between groups.
- Positive correlations were observed between Machiavellian intelligence scores (Global, Tactics, Visions) and dimensional evaluations of antisocial disorder, while a negative correlation was found between Machiavellian Tactics and altruism.
Impact:
- Findings suggest that Machiavellian intelligence plays a significant role in the social functioning and interpersonal strategies of individuals with antisocial traits.
- The results support the hypothesis that an aberrant development of social dominance predispositions may underlie key features of the antisocial syndrome.
- This research contributes to understanding the psychological mechanisms associated with antisocial behavior and its potential manipulation strategies.
