[vmladenov]

Isn’t that inverse, not contrapositive? Here’s how I’m understanding it:

> appeal to authority

authority -> trust

> disappeal to lack of authority

not authority -> not trust

The contrapositive of the first proposition would be

not trust -> not authority

which is a rather different claim.

True, the word was wrong. The point though is that for this logical fallacy, there is an equal and opposite logical fallacy. Saying authority implies truth is just as wrong as saying lack of authority implies falsehood.
