Decision expectation review
Preserve what you expected, compare it with your later rating and record a lesson without rewriting the original expectation.
Your inputs
Start with the example values, then replace them with your own. For tables, keep the vertical bar separators and use a dot for decimals.
A small or biased sample can give misleading results. This tool does not diagnose conditions or justify medical, financial or other consequential decisions.
Tool inputs are processed in your browser and are not submitted by this tool. Existing site analytics and advertising services have their own privacy terms.

How it works
Difference = observed − expected score. Display all decisions and mean absolute difference. Ratings describe your own experience; the table does not prove whether a decision was rational or predict future success.
Worked example
These sample results use the original example inputs in the form. They do not change when you edit your inputs; your own result appears in the workspace.
- Mean absolute difference: 1.5
| Decision | Expected | Observed | Difference | Lesson |
|---|---|---|---|---|
| Route A | 8 | 6 | -2 | Leave earlier |
| New routine | 7 | 8 | 1 | Keep the morning slot |
Read the result carefully
Results depend on the values and assumptions shown above. Change one input at a time to see its effect. A blank or unavailable result means the data does not support a calculation; it is not zero.
