To many developers of technologies that affect public health or the environment. "risk communication" means persuading the public that the potential risks of such technologies are small and

(10) significant danger, they get upset about exotic hazards that pose little chance of death or injury. Because some risk communicators take this persuasive stance, many lay people see "risk communication" as a euphemism for brainwashing done by experts
