Low Defense Bias

A cognitive bias derived from the Scientific Slippery Slope, assuming that any exposure to non‑scientific ideas weakens one’s “defenses” against irrationality. The bias frames the mind as an immune system that must be kept free of “contaminants” to remain healthy; any breach—even a harmless spiritual practice—lowers defenses, making one vulnerable to later infection by dangerous beliefs. It ignores the reality that people routinely engage with multiple knowledge systems (science, art, tradition) without losing critical capacity. Low Defense Bias is often invoked to justify banning or ridiculing non‑scientific practices in educational or public settings.

Example: “She warned that letting her child read Greek myths would lower his defenses against believing in conspiracy theories later—Low Defense Bias treating mythology as a cognitive pathogen.”
