"Why You Should Be Careful About How You Present Performance Metrics ! "
Experiment Outcome
If research participants were informed that their error rate on a task was 5%, compared with an unseen other person's score of 2%, they rated their own performance MORE POORLY than - if they were told their success rate was 95% and the other person's was 98% – even though the two statements convey exactly the same information !
Reason :
That's because the difference between 5 and 2 looms much larger in people's minds than the difference between 95 and 98.
People don't interpret numbers objectively !
Instead, they base their opinions on how numbers make them "FEEL," the research shows.
