Regional Differences in Intergroup Trust Between Northern and Southern China

Area of Science:

• Social Psychology
• Cultural Psychology
• Behavioral Economics

Background:

• Ingroup favoritism, a common human tendency, influences trust decisions.
• Regional cultural variations can significantly impact social behaviors and intergroup relations.

Purpose of the Study:

• To investigate regional differences in intergroup trust between southern and northern China.
• To explore the psychological mechanisms, particularly reciprocity, underlying these regional disparities in trust.

Main Methods:

• Analysis of a large-scale national survey data (N=10,968) on trust attitudes.
• Behavioral trust measurement using game experiments with northern and southern college students (N=156).
• Experimental manipulation to test underlying mechanisms of regional trust differences (N=65).

Main Results:

• Both northerners and southerners display ingroup favoritism when relational cues are present.
• Northerners exhibit ingroup favoritism based on categorical cues, whereas southerners do not.
• Expectations of reciprocity were identified as a key factor explaining regional differences in intergroup trust.

Conclusions:

• Intergroup trust in China is shaped by regional cultural norms and psychological factors.
• Understanding regional variations in trust, like those between North and South China, is crucial for cross-cultural psychology.
• Reciprocity expectations offer a significant explanatory framework for ingroup favoritism differences across Chinese regions.
