The 8 Axes of the Fallacy Spectrum

A framework for evaluating fallacies along eight key dimensions. The 8 axes are: 1) Formal Validity (how well it follows logical form), 2) Informal Soundness (how reasonable it is in context), 3) Evidential Support (how much evidence backs it), 4) Contextual Appropriateness (whether the reasoning fits the context), 5) Intentionality (whether the fallacy is deliberate), 6) Magnitude (how severely it distorts reasoning), 7) Correctability (whether it can be easily corrected), and 8) Consequential Impact (how much harm it causes). These axes allow for nuanced evaluation of fallaciousness.

The 8 Axes of the Fallacy Spectrum Example: "The argument was called a slippery slope. The 8 axes showed: formal validity (weak), informal soundness (some steps plausible), evidential support (little), contextual appropriateness (political debate, where such arguments are common), intentionality (probably deliberate), magnitude (moderate), correctability (hard, as it fit a narrative). The axes explained why the label 'fallacy' wasn't enough—it was fallacious, but in specific ways, to a specific degree."
