Appeal to Authority Fallacy
Also known as: Ad Verecundiam, Argument from Authority
What is Appeal to Authority?
An appeal to authority fallacy occurs when someone cites an authority figure as evidence for a claim, particularly when the authority lacks relevant expertise in the subject being discussed. While expert opinion can be valuable evidence, it becomes fallacious when the authority's expertise is in an unrelated field, when experts in the actual field disagree, or when the authority's opinion is treated as conclusive proof rather than one piece of evidence.
Example
A debate about economic policy at a dinner party.
“A famous actor said this tax plan is terrible, so it must be a bad policy.”
The actor's fame and success in entertainment do not give them expertise in economics or tax policy. Their opinion may be valid, but it should be evaluated on its reasoning and evidence, not on their celebrity status in an unrelated field.
How to Spot It
- An authority is cited whose expertise is in a different field than the claim being made.
- The authority's opinion is treated as definitive proof rather than one perspective.
- No evidence beyond the authority's say-so is provided.
- The authority is invoked to end debate rather than inform it.
How to Counter It
- Ask whether the authority has relevant expertise in the specific subject being discussed.
- Request the evidence or reasoning behind the authority's position, not just their conclusion.
- Note that experts can be wrong and that scientific consensus requires more than one opinion.
- Present evidence from actual experts in the relevant field.
