Philosophy and Rationality Articles

Critical Fallibilism (CF) is a rational philosophy which explains how to evaluate ideas using decisive, critical arguments and accept only ideas with zero refutations (no known errors). An error is a reason an idea fails at a goal (in a context). CF explains why it’s a mistake to judge how good ideas are, how weighty evidence is or how strong arguments are, or to use credences or degrees of belief. We learn by an evolutionary process focused on error correction, not by induction or justification. CF offers an approach to thinking and decision making focused on qualitative differences not quantitative factors.

CF is an original philosophy developed by Elliot Temple which takes inspiration from Critical Rationalism (Karl Popper), Objectivism (Ayn Rand) and Theory of Constraints (Eli Goldratt). CF advocates policies to enable error correction (like my debate policy) and practicing with ideas so your subconscious can automatically use them.
