Political violence and extreme polarization are symptoms of deeper economic anxieties. When people feel economically insecure, they retreat into tribal identities and become susceptible to narratives of anger, which can escalate into violence.

The rise of populism is better understood as a resurgence of humanity's innate "groupish" and tribal instincts. This regression is amplified by a modern cocktail of social media, rapid migration, and weakening political institutions, making it a deeper cultural and psychological phenomenon than just an economic one.

Across history, from Nazis calling Jews "pestilence" to Hutus calling Tutsis "cockroaches," propaganda follows a single playbook. By labeling an out-group as non-human (animals, viruses), it deactivates the brain's social cognition and empathy networks, making it psychologically easier to commit atrocities.

Society hasn't processed the collective trauma of events like the pandemic, leading to widespread emotional dysregulation that prevents clear thinking. To move forward, groups must first feel and acknowledge the fear and grief, rather than just intellectualizing the problems.

When a demographic feels perpetually attacked for an unchangeable trait, they are psychologically primed to unify around that identity. This dynamic explains the rise of controversial figures who capitalize on that reactive sentiment, becoming a predictable societal counter-reaction.

This psychological mechanism flips a switch, intensifying love for one's in-group while enabling murderous hatred for an out-group. It recasts political rivals as existential threats, making violence seem not just acceptable, but morally necessary for the group's survival.

People often agree on the facts of a political event but arrive at opposite conclusions because their internal 'threat monitors' are calibrated differently. One person's 'alarming authoritarian move' is another's 'necessary step for order,' leading to intractable debates.

This concept describes a psychological state where empathy is completely withdrawn from an "out-group." This allows individuals to justify and even celebrate violence against perceived enemies, seeing it not as murder but as a necessary and righteous act in service of their in-group.

A brain study revealed people prefer anger over joy or love. Anger is neurologically rewarding because it offers a simple, powerful feeling of being right and morally superior, making it a potent tool for political mobilization and a driver of tribalism.
