Occam's Razor
Occam's Razor is a principle of reasoning that states, when faced with competing explanations or hypotheses, the one that requires the fewest assumptions should be preferred — all else being equal. Formulated by 14th-century philosopher William of Ockham, it is used across science, medicine, philosophy, and decision-making as a tool for cutting through unnecessary complexity, filtering hypotheses, and resisting the human tendency to construct elaborate explanations for simple phenomena.
Socratic Method
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.
Thought Experiment
A thought experiment is a structured mental simulation used to explore the implications of hypotheses, test intuitions, and derive insights in cases where real experiments are impractical, impossible, or unethical. From Galileo's falling bodies to Einstein's relativity to Rawls's veil of ignorance, thought experiments have driven some of history's most important intellectual breakthroughs — by using imagination as a rigorous investigative tool.
Via Negativa
Via Negativa is a philosophical and practical principle — derived from apophatic theology and popularized in modern decision-making by Nassim Taleb — that holds that we often gain more from removing what is harmful, wrong, or unnecessary than from adding what seems good. In medical ethics, it underlies the Hippocratic 'first, do no harm.' In investing, it is expressed as avoiding certain losses rather than seeking certain gains. In system design, it means removing fragilities rather than adding features. The insight: subtraction is more reliable than addition because we know harms better than we know goods.
