Argument Strength

Argument strength is the common assumption that arguments and evidence come in degrees — some strong, some weak — and that the rational move is to weigh them all and side with the higher total. CF calls these degree arguments: arguments whose effect on a conclusion is a matter of amount, not all-or-nothing. The model spans courtroom advocacy, debate scoring, and everyday “pros outweigh cons” reasoning. Karl Popper kept a version: his critical preferences asked which surviving idea seems best after weighing the criticisms.

CF’s most important original move is to reject argument strength entirely — rejecting two distinct things for two distinct reasons. CR already rejects justificationist positive arguments; CF additionally rejects degree arguments. Positive arguments fail because it only takes one error to cause failure: there is no way to get from “it has good traits” to “it has no errors.” Degree arguments fail differently — they don’t focus on what is important, often scoring a local optimum that doesn’t matter to the goal. Where weighing is numerical, CF adds that summing numbers from incommensurable dimensions is mathematically illegitimate — but that point targets weighted-factor scoring, not positive arguments.

What matters instead is success or failure at a goal, which is digital, not analog: an idea is either refuted for a goal or it is not. So CF replaces strength with decisive criticism under Yes or No Philosophy — a criticism that contradicts an idea by showing it must fail at a stated purpose. A “weak” criticism, undesirable yet compatible with success, does nothing; there are no points to earn.

Where someone sees a strong argument, CF sees a complete argument that reaches a conclusion, a partial argument that is a building block, or no argument — three discrete kinds, not a spectrum. People reach for strength because they cannot organize a whole debate decisively; the remedy is to find the decisive issue, not to tally weights.
