Mental Fatigue: The Hidden Trigger for Aggression and Conflict
A new study supports the controversial 'ego depletion' theory, suggesting that mental fatigue from making difficult decisions can lead to aggressive behavior by wearing down brain areas responsible for self-control. Researchers from the IMT School for Advanced Studies Lucca found that participants who engaged in mentally exhausting tasks showed increased hostility and reduced cooperation, linked to sleep-like activity in brain regions related to decision-making. These findings, published in PNAS, highlight the impact of mental fatigue on behavior, though the theory remains debated.
