🧠 A new study in Deviant Behavior analyzed how adults process social information before acting aggressively, revealing distinct mental steps for impulsive (reactive) versus planned (proactive) aggression.

💡 For reactive aggression, confidence in one's ability to lash out is a key factor. For proactive aggression, the expectation of a reward drives the behavior.

👩‍🔬 Researchers Mariana Sebastião Machado, Josefina Castro, and Carla Sofia Cardoso from the University of Porto surveyed 278 Portuguese adults. They found while overall aggression levels didn't differ significantly between sexes, men tended to view aggressive responses and their outcomes more positively than women.

🔬 In women, believing an aggressive response was acceptable predicted proactive aggression, but reactive aggression was linked to high confidence in acting out alongside a negative judgment of the act itself, potentially due to social conditioning.

😴 Intense boredom can drive people toward aggression, increasing the desire for sensation and stimulation.

💥 This pursuit of high-arousal experiences, known as sensation seeking, can reduce inhibitions and lead to physical aggression and support for military conflict.

📊 A study found that individuals who experience boredom more often also report higher levels of aggressive traits.

🥊 In one experiment, participants exposed to a boring video were more likely to engage in physical aggression by punching a bag harder and more frequently.

🌍 Boredom also increased support for military aggression across the political spectrum in hypothetical international conflict scenarios.
