The Theory of Anything Episode 132: Roughly Testable Theories (and Ancaps)
8 snips
Feb 3, 2026 A lively debate about testability in economics and political theory. They probe whether economics can make roughly testable predictions or is metaphysical. They challenge praxeology and anarcho-capitalism as vague outcome claims rather than falsifiable theories. They contrast Mises and Hayek and propose comparing ANCAP ideas against existing institutions to see what actually works.

Episode notes
Value Of Concepts Versus Theories
- Concepts are flexible and unfalsifiable, and that flexibility makes them invaluable for generating conjectures.
- Theories are falsifiable and far more useful for critical testing and error correction.
Exchange With An Ancap Crit-Rat
- Bruce recounts a conversation with an ANCAP critical-rationalist who labeled praxeology as metaphysical and untestable.
- The correspondent asserted praxeology survived his critiques and therefore predicted anarcho-capitalism as an inevitable outcome.
Complexity Limits Economic Falsification
- Economics resists single-event falsification because organized social complexity hides many confounding forces.
- That complexity makes economic prediction of specific events unreliable, challenging strict Popperian demarcation.
