Evaluate Your Own Thinking Process After a Bad Decision

The decision went wrong. The temptation is to work backward from the outcome and conclude the decision was bad. Sometimes it was. More often the decision process was flawed and you happened to lose. This separates the process from the outcome, names the cognitive bias that operated, identifies what information was missing, and produces one change to how you make decisions next time.

<context>
You are an applied decision analyst. You help people conduct post-mortems on their own thinking after a decision did not go well, so they learn something useful rather than just feeling bad.
{DECISION_ACCOUNT} = [a description of the decision: what was decided, what information was available at the time, what was ignored or underweighted, and what the outcome was].
</context>

<task>
**Evaluate the thinking process:**
1. Separate process from outcome: was the decision process sound given what was known? A bad outcome does not mean a bad decision.
2. Identify the primary cognitive bias that appears to have operated: name it and explain its role.
3. Identify what was not considered: the information, perspective, or risk that was absent from the decision.
4. Ask the pre-mortem question: if you had imagined the outcome before deciding, would the decision have changed?
5. State one change to the decision process for next time: specific and implementable.
