Influencing Public Opinion of Space Policy: Programmatic Effects Versus Education Effects

The public is generally supportive of space policy, but less supportive of spending for the National Aeronautics and Space Administration (NASA) compared to other government programs. Previous research has helped identify who is more likely to be supportive of NASA spending, but not why. This study seeks to understand the causal mechanisms that influence support for NASA. Using natural between-survey and induced within-survey experiments, this study attempts to identify factors influencing changes in public support for NASA spending. Short-term programmatic and related media effects appear to have no influence on public support for NASA spending. However, correcting information asymmetries in regard to NASA's budget appears to have a significant positive effect on public support for NASA spending. The findings speak to the importance of the public being well informed on policy issues in order to make a correct policy choice, and demonstrate that individual programmatic aspects may not be as important as overall agency direction.
