The Nazi party strategically used disgusting imagery, describing Jewish people as dirty, greasy, or slimy. This rhetorical strategy was designed to elicit visceral disgust, thereby dehumanizing an entire population and motivating social avoidance, ostracism, and ultimately, violence.
In the first televised presidential debate, Richard Nixon appeared pale, sweaty, and sickly. This visual presentation likely induced a disgust response in viewers, undermining his credibility and contributing to a shift in public opinion in favor of John F. Kennedy.
Studies consistently find a correlation between how easily a person is disgusted and their political orientation. Higher disgust sensitivity is associated with political conservatism, which may be linked to a broader psychological trait of threat aversion and a preference for tradition over novelty.
Labeling a person or group as 'disgusting' is an effective political tactic because it's an emotional attack, not a logical one. While one can counter claims of incompetence with evidence, an accusation of disgust is nearly impossible to refute rationally, making the target defenseless.
People remain disgusted by an object even when they intellectually know it's safe, such as a sterilized cockroach dipped in a drink. This demonstrates that disgust operates on a 'magical' or symbolic level, bypassing our rational faculties and making it a powerful, irrational force.
Presenting jurors with disgusting evidence, such as vivid color photos of a crime scene, biases them toward finding the defendant guilty. The emotional reaction of disgust can override objective evaluation of the facts, highlighting a significant vulnerability in the criminal justice system.
Unlike other emotions, disgust spreads through contamination in one direction. A single cockroach can render an entire platter of food inedible, but pouring a gallon of honey on the cockroach won't make it less disgusting. This principle highlights the powerful, irreversible nature of disgust.
Two powerful emotions, love and lust, can temporarily mute our disgust response. Love allows a parent to change a dirty diaper without revulsion, while sexual arousal reduces disgust toward bodily fluids. This is a crucial evolutionary adaptation that facilitates essential human behaviors.
Donald Trump's debunked claim that immigrants were eating local pets illustrates a political tactic: linking an out-group to a disgusting act. This emotionally potent story bypasses rational thought, creating a powerful aversion that persists even after being fact-checked.
In an experiment, participants filling out questionnaires in a room with a bad smell rated social groups, such as gay men, more negatively. This demonstrates that incidental feelings of disgust, even from an unrelated environmental source like a smell, can directly influence and bias our social judgments.
A study found that simply reminding people to wash their hands to avoid the flu—priming thoughts of disease and contamination—caused them to temporarily report being more politically conservative. This suggests that activating our underlying disease-avoidance system can influence our high-level political ideologies.
Research shows that individuals who are more easily disgusted in general also tend to exhibit more homophobic attitudes. This link is likely because sexuality involves bodies and fluids, potent disgust triggers, making it easy to elicit an aversive emotional response towards non-normative sexual acts.
