Appeal to Authority
Logical Fallacy入门
Definition
Believing something must be true simply because an authority figure (or celebrity) endorses it, even if that authority is not an expert in the relevant field.
Example
"This famous movie star uses this skincare product, so it must work wonders for skin repair."
如何避免
检查权威人士是否是该领域的真正专家，以及该领域是否存在共识。关注证据本身而非谁说的。
