AKA: "Results-Only Thinking"
Judging a decision based on its outcome rather than the quality of the decision-making process.
Your brain has bugs. Outcome Bias is one of them. Understanding this error pattern helps you catch it before it costs you.
A risky bet that paid off is called "genius." The same bet that failed is called "reckless." Same process, different luck.
High-stakes domains (medicine, law, finance) have developed entire systems to counteract Outcome Bias. If professionals need safeguards, so do you.
This error is driven by Outcomes are visible and unambiguous; decision quality is invisible and complex..
This bias exists because human brains evolved for survival, not accuracy. Outcomes are visible and unambiguous; decision quality is invisible and complex. served our ancestors well. In modern contexts, it often misfires.
In investing: Outcome Bias leads to holding losing positions too long or selling winners too early.
In relationships: This bias causes people to interpret ambiguous signals in ways that confirm existing beliefs about partners.
In work: Outcome Bias makes it harder to update strategies when market conditions change.
In health: People ignore symptoms that contradict their self-image as "healthy" or "young."
Outcome Bias has been studied extensively since the cognitive revolution. Research consistently shows that even warned subjects fall for it—awareness alone doesn't provide immunity.
Evaluate decisions by the information available at the time. Good process can yield bad outcomes, and vice versa.
Seek disconfirming evidence: Actively look for data that challenges your current belief.
Use decision journals: Write down predictions before outcomes are known, then review accuracy.
Consult diverse perspectives: People with different backgrounds spot different biases.
Implement decision rules: Pre-commit to criteria before emotionally charged situations arise.
Time-box decisions: Revisit important conclusions after a cooling-off period.
Some brains are more susceptible to this than others. Test your Intelligence to find out.
Judging a decision based on its outcome rather than the quality of the decision-making process.
The alternate name "Results-Only Thinking" captures the intuitive essence of the bias. Outcome Bias is the formal psychological term, while "Results-Only Thinking" describes what it feels like in practice.
Evaluate decisions by the information available at the time. Good process can yield bad outcomes, and vice versa.
The underlying mechanism is outcomes are visible and unambiguous; decision quality is invisible and complex.. Human brains evolved heuristics for speed and survival, not accuracy in modern contexts.
Yes. Intelligence doesn't provide immunity—sometimes it makes the bias worse because smart people are better at rationalizing. Awareness and structured decision processes are more protective than raw IQ.
