Honor by association
The logical fallacy
of honor by association
is claiming that someone or something must be reputable because of the people or organisations who are related to it, or otherwise support it.
- George W. Bush will make a good president, because his father was a good president.
- Alice is a lawyer, and Alice thinks highly of Bob. Therefore, Bob must be an expert in law.
This fallacy is therefore the opposite of guilt by association
, and also shares some characteristics of an appeal to authority
