Contemporary parasite stress curvilinearly correaltes with outgorup trust: Cross-country evidence from 2005 to 2014

There will be a U-shaped correlation between outgroup member trust and parasite stress.

Both the linear and curvilinear correlations were significant. The curvilinear shape was also U-shaped.
