Believing the system is just reduces perceived corruption and corrupt intent. Institutional trust mediates this effect, offering insights into human behavior and societal norms.
Area of Science:
- Social Psychology
- Political Science
- Behavioral Economics
Background:
- System justification theory posits that people are motivated to justify existing social systems.
- Previous research on system justification's effect on corruption perception yields mixed results.
- Understanding factors influencing corruption perception and intention is crucial for societal well-being.
Purpose of the Study:
- To investigate the effect of general system justification on corruption perception and intention.
- To explore the mediating role of institutional trust in the relationship between system justification and corruption.
- To clarify the ambiguous findings regarding system justification and corruption.
Main Methods:
- Three studies were conducted, employing correlational and experimental designs.
- Study 1 used questionnaires to assess the relationship between general system justification, corruption perception, and intention.
- Study 2 experimentally manipulated system justification by varying system threat levels.
- Study 3 examined the mediating role of institutional trust through correlational and experimental approaches.
Main Results:
- General system justification was negatively associated with both corruption perception and corrupt intention.
- Institutional trust was found to mediate the relationship between general system justification and corruption.
- Findings align with some previous research but offer a more nuanced understanding.
Conclusions:
- General system justification appears to reduce both the perception and intention of corruption.
- Institutional trust is a key psychological mechanism linking system justification to corruption.
- These findings contribute to understanding the psychological underpinnings of corrupt behaviors.
