False dilemma

What it is

Presents only two options when more exist, so that rejecting one seems to force acceptance of the other.

Example "You're either with us or against us."

Straw man fallacy
Straw men often cast the opponent as holding an extreme position, which sets up a false dilemma.
Framing effect bias
Presenting a choice as exactly two options is a framing choice that shapes what people select.
Argument to moderation fallacy
A false dilemma gives two extremes, and the argument to moderation then splits the difference between them; both ignore the real range of options.
Loaded question fallacy
Loaded questions often allow only answers that accept the hidden assumption, creating a false dilemma.
Nirvana fallacy fallacy
The nirvana fallacy sets a flawed real option against an impossible perfect one, a false dilemma between imperfection and perfection.
Alternative blindness bias
A false dilemma hides the other options from view, which is alternative blindness imposed from outside.
