Law of the Fallacy Possibility

The principle that fallacies represent possibilities, not certainties—they identify ways reasoning could go wrong, not guarantees that it has. Calling an argument a slippery slope doesn't prove it's wrong; it identifies a possibility of error that must be evaluated. Calling an argument ad hominem doesn't settle the matter; it raises a possibility that must be assessed. The law of the fallacy possibility reminds us that fallacy labels are hypotheses, not verdicts. They open inquiry rather than closing it. The real work is not in naming the fallacy but in determining whether it actually occurred—whether the possibility is actual.

Example: "She said his argument was a slippery slope. He agreed it was possible, then asked for evidence that the slope would actually slide. The law of the fallacy possibility said: naming the possibility doesn't prove it's real. The debate shifted from labeling to evidence, which is where it should have been all along."
