Objective
This study examines how people evaluate prosocial initiatives—in particular, whether they exhibit optimism bias when asked to consider the outcomes of a hypothetical initiative that is described to take place in the nonprofit, business, or government sector. It also assesses the conditions under which optimism bias is malleable.
Methods
We use a survey with an experimental component to compare subjects’ evaluations of a hypothetical initiative across a set of priming (positive prime, negative prime, no prime) and sector (nonprofit, government, business, social business) conditions.
Results
We find evidence that optimism bias is widespread, regardless of the sector in question. Subjects are only inclined to alter their assessments when provided with new information that is positive (in contrast to new information that is negative).
Conclusion
The findings offer qualified support for the blurring hypothesis, suggesting that sector may be losing its status as a defining characteristic of the organizational landscape.
