CORE DEFINITION

False equivalence uses faulty reasoning to assert equivalence, for example treating a shared feature as sufficient while ignoring relevant differences in degree, context, or consequences. The subjects need not be wholly incomparable; the similarity fails to support the claimed equivalence. Deliberate concealment is not required.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Breaks the mental laziness of "blaming both sides equally." It reminds us that because two things share a commonality (e.g., "both are at fault"), it does not mean they are equal in nature, degree, or consequence. It is a scalpel for analyzing complex ethical and political issues.

Anchor fast decisions

The inference jumps from similarity in one respect to equivalence in the respect needed for the conclusion, omitting relevant differences. A criticism must explain why a difference matters; merely finding any difference does not invalidate a comparison.

Ugly Duckling Theorem

Counting all extensional properties equally over a finite set gives different object pairs the same number of shared properties; useful similarity requires selecting or weighting features.

Shotgun Parsing

An anti-pattern in which data processing and input validation are mixed together, causing parsing logic to be scattered throughout the code, making the system prone to crashes or attacks when encountering abnormal input.
