Fallacy · Rigging the question
Motte and bailey
Also called: Shifting ground
Advancing a bold claim, retreating to a modest one when challenged, then advancing again.
What it is
The name comes from a medieval castle: the bailey is pleasant land that is hard to defend, the motte is a mound easy to defend. The arguer lives in the bold claim (the bailey), retreats to an obvious one (the motte) when pressed, and returns once the challenge has passed, as if the bold claim had been defended.
An example
“Schools are destroying children’s creativity.” Challenged, “I only mean schools could do more for creativity.” Everyone agrees, and later, “As we established, schools destroy creativity.”
How to spot it
Notice two versions of the claim, a strong one and a safe one, being used as if they were the same.
How to answer it
“I agree with the modest version. Are you still claiming the strong one? That needs its own evidence.”
When it is not a fallacy
Retreating to a more modest claim is honest when you say so and give up the bold one. The fallacy is returning to the bold claim later as if the modest one had defended it.
