Bright Lines, Risk Beliefs, and Risk Avoidance: Evidence from a Randomized Intervention in Bangladesh

By Lori Bennear, Alessandro Tarozzi, Alexander Pfaff, H. B. Soumya, Kazi Matin Ahmed and Alexander van Geen


We randomized 43 villages in Bangladesh to receive information on well-water arsenic that emphasized water safety relative to the national standard (bright-line message) or provided additional information on how risks from exposure increase with arsenic levels (gradient message). The gradient message led to 50% more switching of water sources when the arsenic level was moderately unsafe, but 40% less switching at high arsenic levels. The differences in behavior are at least partially explained by differences in risk perception that developed after the information campaign.Beliefs; Information; Health risk; Arsenic; Drinking water; Bangladesh
