Abstract
This paper examines Amar Bhidé's modernization of Knightian uncertainty as presented in Uncertainty and Enterprise. While Frank Knight's seminal 1921 distinction between risk and uncertainty remains influential, Bhidé argues that uncertainty, as commonly conceived, has become a conceptual dead end. Instead, he proposes an updated framework where uncertainty is understood as doubt arising from missing information about known unknowns. This modernization aims to make uncertainty a more operationally useful concept, particularly in the context of entrepreneurship and firm decision-making. This paper reflects on the applicability of Bhid & eacute;'s ideas beyond entrepreneurship, discussing their relevance to risk management, economic decision-making, and firm strategy. While Bhid & eacute; downplays the significance of Knight's risk-uncertainty dichotomy, this paper argues that the distinction remains analytically valuable, especially in fields such as finance and corporate strategy, where statistical tools play a role in managing risk. Additionally, the discussion revisits the concept of "unknown unknowns" and considers its practical implications for decision-making under extreme uncertainty. Drawing on examples from financial markets, corporate reporting, and mountaineering, the paper highlights how firms and individuals navigate risk and uncertainty in diverse settings. Ultimately, the analysis supports Bhid & eacute;'s call for a broader, more empirically grounded approach to uncertainty.
