Bright Lines, Risk Beliefs, and Risk Avoidance: Evidence from a Randomized Intervention in Bangladesh
Date Written: October 1, 2010
Abstract
This paper provides evidence on the effects of risk presentation on health behaviors using data from a cluster randomized controlled trial in risk presentation regarding arsenic in drinking water in Araihazar district of Bangladesh. The intervention was designed to test whether highlighting the existence of a gradient in arsenic risk — exposure risk increases with the level of arsenic and lower arsenic exposure is always better — led to better choices relative to “bright line” information provision that focuses on whether the arsenic level is above or below the country standard of 50 parts per billion (ppb).
