Recent scientific research has illuminated a profound truth about how stress influences human social behavior: While stress may foster unity and generosity among members of the same group, it simultaneously stirs up aggression and suspicion toward those outside the group. These insights, highlighted in a July 2025 report by Psychology Today, draw from a study published in the Proceedings of the National Academy of Sciences (PNAS) and have far-reaching implications for societal cohesion, especially in rapidly changing societies like Thailand.

Groundbreaking research from Heinrich Heine University Düsseldorf has illuminated the double-edged effects of stress: while it binds people more closely to their in-group, it simultaneously drives hostility toward perceived outsiders. Published this week in the Proceedings of the National Academy of Sciences, the findings provide a nuanced neurobiological perspective on why group conflicts—even when costly to all—remain so persistent worldwide. This research offers valuable insights into the psychological forces underpinning social divisions, with implications for Thai society and global communities navigating rising polarization.

In a groundbreaking discovery, researchers have found that artificial intelligence (AI) systems can spontaneously develop human-like ways of communicating, forming social conventions and group norms without human direction. Published in Science Advances, the peer-reviewed study demonstrates that groups of large language model (LLM) AI agents like ChatGPT, when communicating together, are capable of building their own shared language and collective behaviors—a finding that could reshape how we think about both AI development and its integration into society (The Guardian).
