CORE DEFINITION

Before a debate begins, negative information about the opponent is spread to the audience (e.g., "He is a liar"), so that anything the opponent subsequently says (even if it is the truth) loses credibility because the source is contaminated.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Identify preemptive smearing. This is a malicious preset frame. When hearing phrases like "No matter what he says, remember he has XX background," be alert that your cognitive well has been poisoned, and you must force yourself to independently review the information itself.

anchor

Anchor fast decisions

Before argumentation, contaminate the opponent's source with negative labels, causing the audience to distrust any of their arguments preemptively. It is a preset variant of argumentum ad hominem that undermines rational discussion.
