Equivalent facts or options can produce different judgments when presented in different frames.
Limited evidenceSupporting studies exist, but they are few and conditions matter.
Example
In a fictional example, switch between 80% complete and 20% incomplete while keeping the denominator and period fixed and both views available.
Why it works
The 1981 study demonstrates preference reversals under alternative formulations of a decision problem. This interface illustrates attribute wording; it does not reproduce the risky-choice experiment.
On the web
Show completion and non-completion for the same population and period so users can inspect both sides and the conditions.
When it backfires
Changing population, denominator or period is not equivalent framing. Check comprehension and cancellations as well as choice rates when testing wording.
