Summary
Aggression significantly influences group financial decisions. Highly aggressive individuals favor risky strategies based on personal data, dominating group choices rather than reflecting individual risk tolerance.
Area of Science:
- Behavioral Economics
- Social Psychology
- Decision Science
Background:
- Personality traits can impact financial decision-making.
- Group dynamics introduce complexities to individual financial choices.
Purpose of the Study:
- To investigate the effect of the personality trait aggression on group financial decision-making.
- To differentiate the influence of aggression on group versus individual financial behavior.
Main Methods:
- A laboratory experiment involving group portfolio choice.
- Measurement of subject aggression using a standard psychology test.
- Analysis of investment strategy recommendations based on personal and group information.
Main Results:
- Highly aggressive subjects recommended riskier investment strategies aligned with their own information.
- This effect was prominent in group settings but absent in individual decision-making.
- Aggression's impact was linked to a disposition to dominate group decisions, not just risk preference.
Conclusions:
- Aggression is a key factor in group financial decision-making, driving individuals to impose their strategies.
- The study distinguishes between dispositional aggression and general risk-taking or cognitive biases in financial contexts.

This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
