Logical Fallacies
These are the most common fallacies found in conspiracy theory arguments. Learning to recognize them is the first step toward evaluating claims critically — whether they come from conspiracy theorists or from mainstream institutions.
Ad Hominem
RhetoricalAttacking the person making an argument rather than the argument itself. In conspiracy contexts, dismissing debunkers as "shills" or "paid agents."
Anecdotal Fallacy
StatisticalUsing personal stories or isolated examples instead of statistical or scientific evidence. One person's experience does not establish a pattern.
Appeal to Ignorance
LogicalClaiming something is true because it hasn't been proven false, or false because it hasn't been proven true. Absence of evidence is not evidence of absence — but it's also not evidence of presence.
Argument from Incredulity
LogicalConcluding something must be false (or conspiratorial) because it seems personally unbelievable. "I can't understand how X could happen, therefore it didn't."
Cherry-Picking
LogicalSelecting only evidence that supports a predetermined conclusion while ignoring contradictory data. Also known as the fallacy of incomplete evidence.
False Dichotomy
LogicalPresenting only two options when more exist. "Either you believe the official story, or you're a free thinker." Ignores the many positions between complete acceptance and total rejection.
Genetic Fallacy
LogicalJudging something as good or bad based on where it comes from, rather than its actual merits. Dismissing evidence because of its source without evaluating its content.
Gish Gallop
RhetoricalOverwhelming an opponent with a rapid succession of many specious arguments, half-truths, and misrepresentations. Named after creationist Duane Gish.
Moving the Goalposts
LogicalChanging the criteria for proof or acceptance after the original criteria have been met. When evidence meets one demand, a new demand is introduced.
Nirvana Fallacy
LogicalComparing a real-world situation to an unrealistic ideal, then concluding the real thing must be flawed or fake. Also called the perfect solution fallacy.
Post Hoc Ergo Propter Hoc
LogicalAssuming that because event B followed event A, A must have caused B. Correlation is mistaken for causation.
Slippery Slope
LogicalArguing that one event will inevitably lead to a chain of negative consequences without evidence for the causal links.
Texas Sharpshooter Fallacy
StatisticalFinding a pattern in random data by focusing on similarities and ignoring differences. Named after a joke about a shooter who fires at a barn, then paints a target around the bullet holes.
Tu Quoque
Rhetorical"You too" — deflecting criticism by pointing out that the critic is guilty of something similar. Does not address the original argument.
