Fact-Checker, Check Thyself
Thorsteinn Siglaugsson was wickedly accurate in sketching the typology of fact-checking techniques. Create a straw-man argument that can be easily knocked down. Assert that a claim is not supported by evidence, is questioned by other experts, lacks context, is misleading, or is only partly true, etc. Engage in ad hominem attacks against the person rather than with their evidence and argument.
