False dichotomy

The logical fallacy of false dichotomy or false choice occurs when one provides only two (or a few) answers to a question, giving the illusion that these choices exhaust all possibilities, when in fact they don't. Some examples include:

• How did life arise? It has to be either evolution or creation.

In fact, both may be wrong.

• Based on what he claimed, Jesus was either a liar, a lunatic, or the Lord.

This ignores other possibilities, such as "legend".

• You're either with us or against us.

I might not stand in your way, but cannot actively support your course of action.
