Inconsistent Comparison

The systematic study of comparative fallacies began with Aristotle, whose c. 350 BCE work Sophistical Refutations — the first known taxonomy of logical errors — catalogued misleading arguments including those that shift terms mid-comparison. The specific label "inconsistent comparison" emerged from the informal logic and critical thinking movements of the late 1970s and 1980s, which systematized such errors under the broader category of false equivalence.
