Why Results Trick You Into Thinking a Decision Was Good: Outcome Bias

By E. J. Kilner

Do you reward a bad decision that worked out by accident? Do you punish a good decision that failed due to bad luck? If so, you have fallen into outcome bias.

Outcome bias is the cognitive error that tricks you into judging a decision by its result rather than by the quality of the thinking behind it. This single bias distorts learning, destroys good decision making habits, and convinces you that luck is skill.

In Outcome Bias: Why Results Trick You Into Thinking a Decision Was Good, behavioral psychology author E. J. Kilner delivers the ninth volume in The Cognitive Bias Codex series. This book isolates one powerful bias and shows exactly how it operates in business, investing, medicine, sports, parenting, and personal growth.

You will learn to separate process from results. You will build decision frameworks that work even when luck runs against you. You will stop rewarding randomness and start rewarding reasoning.

The book provides a decision hygiene protocol, a personal decision log system, and practical scripts for resisting outcome bias in other people. Whether you are a manager, investor, coach, parent, or professional, this book will change how you evaluate every choice you make.

Stop letting results lie to you. Learn to judge decisions the right way.
