| A logical fallacy in which a threat is made instead of a logical argument to support the conclusion.
Example: "If you don't agree that I'm right, then you're fired" doesn't prove he's right.
To prove use of Appeal to Force, identify the threat and show that is has no relation to the truth of the proposition.
Don't confuse this with a proof that Bad Things will happen, but see also Slippery Slope. |
