Stress, Group Unity, and Intergroup Tension: Insights for Thai Society
A new study from a leading German university explores how stress can both strengthen in-group bonds and increase hostility toward outsiders. Published in a major scientific journal, the research provides a neurobiological lens on why group conflicts persist and how polarization takes hold in Thai communities and beyond.
Researchers in comparative psychology, with clinical neuroscience support from a major hospital, conducted a psychopharmacological experiment. Participants were given a cortisol analog to simulate stress, a drug to raise noradrenaline, both compounds, or a placebo. They formed groups and competed in economic games with real financial stakes to mirror cooperation and rivalry in real life.
