New blog post! I summarize our recent paper (www.pnas.org/doi/10.1073/...) how stress concurrently fosters ingroup support and outgroup competition, and what this has to do with societal polarization and conflict.

Does stress make us more aggressive or more helpful? New research suggests it does both. This dual effect may drive growing societal polarization and the persistence of conflict.

“We hope this research sparks further studies that move beyond either-or models and ask when, how, and why stress brings out our more cooperative or competitive sides. […] In a world marked by rising division, it feels especially timely to understand how stress can both unite and divide us.”

Acute stress can enhance cooperation within groups while simultaneously increasing hostility toward outsiders, driven by distinct neurochemical pathways. doi.org/g9s8sw
How stress strengthens group bonds—and fuels intergroup conflict
Why do violent conflicts between groups persist—even when all sides suffer as a result? Researchers from psychology and medicine at Heinrich Heine University Düsseldorf (HHU) have now examined the dual effect of physiological stress messengers on social behavior in intergroup conflicts.

New paper in @pnas.org! How does stress affect our social decisions in conflict? More aggression (fight-or-flight)? Or more altruism (tend-and-befriend)? Our new study suggests: it’s not either/or, stress promotes both at once, depending on the neurochemical balance and the social context. 🧠
