This note focuses on George Soros's challenge to macroeconomics and finance theory that any valid methodology of social science must explicitly recognize fallibility in a Knightian sense. We use a simple algebraic example to sketch how extant models formalize fallibility. We argue that contemporary theory's epistemological and empirical difficulties can be traced to assuming away fallibility in a Knightian sense. We also discuss how imperfect knowledge economics provides a way to open mathematical models to such fallibility, while preserving economics as an empirical science
