The act of shifting the required standard of evidence after some evidence has been provided. When the initial “proofpost” is met or approached, the arguer redefines what constitutes valid proof, invalidating the newly presented evidence without engaging with it.
Moving the Proofpost Example:
“Show me one major economist who agrees with your policy.”
You cite a Nobel laureate.
“Well, he’s old and out of touch. Show me a young, heterodox economist who isn’t part of the establishment.”
They’ve just moved the proofpost to dismiss the fulfilled request.
