Cable news and social media don't show the average person who votes differently. They blast the loudest, most cartoonish "professional lunatics" from the opposing side. This creates a false impression that the entire opposition is extreme, making tribalism seem rational.

Violent acts are not random; they often represent the logical conclusion within a person's specific frame of reference. If an ideology convinces someone they are fighting a Hitler-like evil, then assassination becomes a moral duty, not a crime. The danger lies in these justifying belief systems.

In populist moments, leaders often abandon the idea of compromise and instead treat the opposing side as an enemy to be defeated. Language describing American cities as "war zones" or "training grounds" reveals this divisive mindset, which prioritizes conflict over unity.

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.

This concept describes a psychological state where empathy is completely withdrawn from an "out-group."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.

An ideologue, even an anarchist advocating against the state, may support a massive state action if it serves a higher strategic purpose—in this case, disrupting a system they oppose. The perceived hypocrisy is dismissed as irrelevant when compared to the desired outcome, framing it as a solution, not a preferred method of governance.

Effective political propaganda isn't about outright lies; it's about controlling the frame of reference. By providing a simple, powerful lens through which to view a complex situation, leaders can dictate the terms of the debate and trap audiences within their desired narrative, limiting alternative interpretations.

In the aftermath of political violence, the targeted group often mirrors the very dehumanizing tactics they condemn. While correctly identifying an attacker's ideology, they risk escalating the conflict by applying labels like 'evil' to the entire opposing side, thus perpetuating the cycle of radicalization that fuels violence.

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.
