Us vs. Them

Dividing the world into two camps — people like us (good, trustworthy) and people not like us (dangerous, wrong). It exploits a deep human tendency to favor our own group. Once you accept the division, information from "them" gets automatically discounted.

Tajfel's Social Identity Theory (1979); Minimal Group Paradigm

Fear appeal

Presenting a vivid threat and then offering a specific action as the way to avoid it. Always structured as: "Something terrible will happen unless you do X." Most effective when the threat feels personal and the action feels achievable.

Witte's Extended Parallel Process Model (1992)

Intensity amplification

Inflating the importance, drama, or shock value of information using superlatives, alarming framing, and emotional language. Once your alarm system activates, you stop evaluating proportionality.

Cultivation theory (Gerbner, 1969); availability heuristic (Tversky & Kahneman, 1973)

Appeal to authority

Citing an expert or institution to support a claim, substituting their credibility for evidence you can evaluate yourself. Legitimate when the authority is relevant; manipulative when they aren't qualified or when the citation is vague.

Argumentum ad verecundiam (Locke, 1690); Cialdini's Authority principle (1984)

Moral outrage

Provoking a sense that something is deeply unfair or wrong, activating a feeling that demands action — sharing, protesting, punishing — before you've fully evaluated the situation. It's one of the most viral emotions online because it combines anger with righteousness.
