The premortem (imagine the project already failed)
Before starting, assume the plan has already failed and ask why — then fix it now.
Why it works
A decision-making application: imagining a future failure as already certain (prospective hindsight) loosens overconfidence and surfaces risks that forward-looking optimism hides. Because the failure is treated as fact, people generate more and more specific reasons for it than when merely asked "what might go wrong?" — which lets you strengthen the plan before committing.
How to do it
- Before launching a plan, imagine it’s a year later and the plan failed badly.
- Write the plausible reasons it failed, as if explaining a known outcome.
- Turn the top reasons into changes you make to the plan now, or into if-then contingencies.
Evidence
The premortem draws on research showing "prospective hindsight" (imagining an outcome as having already happened) increases the number and specificity of reasons people generate. It’s a recognized decision-quality technique. (observational)
The prospective-hindsight effect is studied; benefits to real-world outcomes depend on whether the identified risks are actually acted on. It’s a planning tool, not an emotional-resilience exercise.
Common mistake
Running it as a pessimism ritual that lists risks no one then addresses. The premortem only pays off when the surfaced failures change the plan or become contingencies.
