A rhetorical fallacy common in online science communication, skeptic communities, and anti-pseudoscience circles where any expression of doubt, criticism of scientific institutions, or engagement with non-scientific beliefs is treated as the first step down an inevitable path toward severe anti-science and harmful practices. The scientific slippery slope assumes that questioning a study means you reject all science; that being open to alternative medicine means you'll abandon evidence-based treatment; that entertaining a spiritual belief means you're one step from vaccine denial. In reality, most people hold complex, contextual views that don't slide into extremism. The fallacy functions as a thought-terminating cliché, allowing debunkers to dismiss nuance without engagement. It protects scientific orthodoxy by making any deviation seem dangerous, conflating skepticism of particular claims with rejection of science itself, and turning genuine epistemic humility into a perceived threat.
Example: "He suggested that peer review might have flaws, and they immediately accused him of being anti-science. Scientific Slippery Slope: a reasonable critique was treated as the first step toward burning textbooks."
