Definition
Zero-Sum Bias is the cognitive error of perceiving a situation as being like a zero-sum game—where one person’s gain is necessarily another person’s loss—even when the situation is actually non-zero-sum (cooperative or win-win).
- How to read: “Zero-sum bias.”
- Meaning: The false belief that “the pie is fixed.”
Why It Matters
Zero-sum thinking is a primary driver of Envy, social conflict, and protectionism. In business and economics, it prevents people from seeing opportunities for mutual growth, leading to destructive competition over fixed resources rather than the creation of new value.
Core Concepts
- Fixed-Pie Fallacy: The assumption that there is a limited amount of wealth, status, or success, and that taking some means there is less for everyone else.
- Zero-Sum Game: A mathematical situation where the total gains and losses of all participants sum to zero (e.g., poker, chess).
- Non-Zero-Sum Reality: Most modern economic interactions and scientific collaborations are non-zero-sum; the “pie” grows through innovation and trade.
