Logical Biases

Systematic patterns of deviation from norm or rationality in the application of logical rules, often driven by emotion, worldview, or cognitive shortcuts. This isn't about formal fallacies, but about the biased choices we make within logic: which premises we accept, which inferences we draw, and which counter-arguments we entertain. It's the subjectivity hidden inside the objective shell of logic.

Logical Biases Example: Two people see the same data on tax cuts. One, with a pro-market logical bias, immediately infers it will stimulate investment. The other, with an equity-focused logical bias, infers it will increase inequality. The same logical tool (inference from data) is wielded to different ends based on prior ideological commitments.

Logical Biases

Systematic distortions in reasoning that arise not from breaking logical rules but from the way logical systems themselves are constructed, selected, and applied. Unlike cognitive biases (which are psychological), Logical Biases are built into the logic we use—the assumptions that certain logical forms are universally valid, that classical logic is the only logic, that formal validity guarantees truth. Logical Biases include: preferring deductive over inductive reasoning even when deduction isn't appropriate; treating logical consistency as the highest virtue when life requires contradiction; assuming that what's logically possible is actually possible. Logical Biases are what happen when logic becomes ideology—when the tool becomes the master.

Logical Biases "He keeps demanding that my ethical argument be deductively valid. That's Logical Bias—applying deductive standards to ethics, which isn't deductive. His logic biases him against forms of reasoning that don't fit his logical framework. Logic should serve inquiry, not constrain it. When logic becomes a bias, it stops being logic."
