When good = better than average
Abstract
People report themselves to be above average on simple tasks and below average on difficult tasks.This paper proposes an explanation for this effect that is simpler than prior explanations. The new explanation is that people conflate relative with absolute evaluation, especially on subjective measures.The paper then presents a series of four studies that test this conflation explanation.These tests distinguish conflation from other explanations, such as differential weighting and selecting the wrong referent.The results suggest that conflation occurs at the response stage during which people attempt to disambiguate subjective response scales in order to choose an answer.This is because conflation has little effect on objective measures, which would be equally affected if the conflation occurred at encoding.
