Lower Defense Bias

A close variant of Low Defense Bias, emphasizing the process of defense reduction. It posits that each encounter with non‑scientific ideas incrementally reduces a person’s resistance to pseudoscience, eventually reaching a threshold where critical thinking collapses. The bias is often used in discussions about public science communication, where advocates treat any engagement with alternative medicine as a step down a slope toward total rejection of evidence‑based medicine. Like its counterpart, it assumes a linear, inevitable progression that research does not support.

Example: “He claimed that using acupuncture for back pain would lower her defenses against homeopathy, then against vaccine denial—Lower Defense Bias assuming a chain reaction that rarely happens in real life.”
