Falsification, developed by philosopher Karl Popper, is the principle that a claim is only scientific if it is possible in principle to prove it wrong. Popper's central insight: science advances not by confirming theories but by systematically trying to disprove them. The theories that survive repeated, rigorous attempts at falsification are our best current knowledge — not because they're proven true, but because they've resisted being proven false.
Inductive reasoning moves from specific observations to general conclusions; deductive reasoning moves from general principles to specific conclusions. Together, they form the two fundamental modes of logical inference — and understanding which mode applies to a given problem determines whether your conclusions can be certain (deductive) or only probable (inductive). Most real-world problem-solving combines both, but knowing which you're using prevents overconfidence and logical errors.
The Socratic Method is a form of cooperative dialogue in which a questioner leads an interlocutor through a series of probing questions to expose inconsistencies, clarify assumptions, and reach more precise understanding. Developed by the Athenian philosopher Socrates (469–399 BC) and documented by Plato, it is the foundation of Western intellectual inquiry, legal cross-examination, scientific peer review, and Socratic teaching in law and business schools.
Steel Manning is the intellectual practice of constructing the strongest possible version of an opposing argument — the opposite of straw-manning. Rather than attacking the weakest or most distorted version of a position, steel manning requires finding and engaging with the best version, the most sophisticated defence, and the most generous interpretation. It is both an epistemic virtue (a commitment to truth-seeking) and a practical tool for stronger thinking and more productive disagreement.
Steel Manning, in problem-solving contexts, is the practice of constructing and seriously engaging with the strongest version of an opposing position, hypothesis, or approach — rather than the weakest (straw man) version. Applied to problem diagnosis, it means genuinely considering the most compelling evidence that your current solution is wrong, that your root cause hypothesis is incomplete, or that an alternative approach would work better.
