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 should be ignored. Those who communicate risks in this way seem to believe that lay people do not understand the actual nature of technological persuasive stance, many lay people see “risk communication” as a euphemism for brainwashing done by experts.
Since, however, the goal of risk communication should be to enable people to make informed decisions about technological risks, a clear understanding about how the public perceives risk is needed. Lay people’s definitions of “risk” are more likely to reflect subjective ethical concerns than are experts’ definitions. Lay people, for example, tend specific risks of electromagnetic fields produced by high-voltage power transmission well enough to make informed decisions.
Risk communication should therefore be based on the principle that people process new information in the context of their existing beliefs. If people know nothing about a topic, they will find messages about that topic incomprehensible. If they have erroneous beliefs, they are likely to misconstrue the messages. Thus, communicators need to balanced material that tells people what they need to know to make decisions about technological risks.
What this question is testing
Topic
The author is pushing back on a common but misguided approach to "risk communication" — and arguing for one that respects how regular people actually think.
Framework
Highlight Noteworthy. The author isn't neutral; they're explicitly criticizing one approach and recommending another.
Main Point
Here's the simpler version: when companies want to introduce a risky technology, "risk communication" often means The author thinks that's wrong. The real job of risk communication is helping people make informed decisions. Lay people aren't actually as bad at understanding risk as experts assume — they just weight risks ethically and use frameworks that come from their existing beliefs. So the way to communicate well is to find out what people already know and believe, then design messages around that.
P1: The wrong approach
For a lot of technology developers, "risk communication" means persuading the public the risks are small and shouldn't worry them. They cite studies showing lay people care about exotic hazards while ignoring everyday ones. So lay people understandably feel like risk communication is just expert spin.
P2: But lay people aren't that bad at risk
The real goal should be helping people make informed decisions. Lay definitions of risk reflect ethical concerns — for example, putting more weight on risks to kids than on risks to consenting adults. But when asked to rank hazards by annual fatalities directly, lay people do reasonably well. The studies claiming lay people are clueless often use bad methods. And in a recent study, lay people understood specific risks (electromagnetic fields from power lines) well enough to make informed decisions when given facts and time.
P3: The right principle for design
Risk communication should be designed around a simple principle: people process new information through their existing beliefs. If they know nothing, the message goes over their heads. If they hold mistaken beliefs, they'll fit the new message into the wrong framework and misread it. So the people designing the message have to know what their audience already thinks. The author cites a radon-risk study where researchers used interviews and questionnaires to figure out what to put in their brochure — and people who read it understood the risks much better than people who read a generic government brochure.
