A focused ebook for entrepreneurs, managers and finance leaders that applies behavioral finance to business contexts — pricing, investment decisions, forecasting, and customer spending behavior. The guide identifies predictable cognitive traps (overconfidence, sunk cost, confirmation bias) and provides actionable frameworks to design decision processes that reduce bias, improve forecasting, and align incentives. Includes templates to run decision audits and quick experiments to validate business assumptions. (Keywords: business finance psychology, decision-making.)
