Why Classic Maya cities rose and fell

Classic Maya cities rose due to climate downturns, intergroup conflict, and strong economies of scale, while deurbanization occurred when environmental degradation outweighed urban benefits. The study integrates population ecology theory and resolves the paradox of why agrarian populations would aggregate despite high costs.

Research shows anger, not fear, shifts political beliefs

Recent psychological research from Washington University in St. Louis found that anger, not fear, contributes to shifts in political attitudes. Anger causes people to lash out and seek retribution, leading to a shift towards conservative views on issues related to the threat. However, this effect is narrow, with no impact on unrelated ...
