Support conclusions by citing relevant expertise and credible sources.
Last updated
What it is
A logical reasoning pattern that supports claims by citing respected experts, institutions, or authoritative sources. While this can be effective when the authority is relevant and qualified, it becomes a fallacy when the authority lacks expertise in the specific domain. Understanding this distinction helps you use credible sources effectively while avoiding weak appeals to inappropriate authorities.
