 Suppose the officials have done enough to reduce the risk. Leaflets have been delivered to all households, announcements made on radio, television, and social media, advertisements placed in newspapers, barriers erected around the excavation site, warnings posted at all entrances, and so on. But now consider one citizen of the city (call her Curious), who is counter-suggestible. Warnings and barriers merely serve to pique her curiosity. Curious had no prior interest in hazardous waste. But she now develops a desire to see what all the fuss is about. Ignoring the warnings, Curious climbs over the barriers and exposes herself to a dangerous dose of hazardous chemicals.
