From page 4...
... Good risk communication depends on understanding more than quantitative risks and benefits; background experiences and values also influence the process. For example, people who have a general mistrust of government or big business may be less likely to accept the vaccine risk estimates published by government health agencies or vaccine manufacturers.
From page 5...
... A science writer commented that people pay more attention to dramatic, new, or unknown risks or risks conveyed within the context of a personal story. Most people will give proportionally more weight to a dramatic risk of dying from an airplane crash, for example, than to the risk of dying from lung cancer due to smoking, even though the latter is more likely.
From page 8...
... For example, the data on lung cancer treatment suggest that surgical treatment has a higher initial mortality rate but radiation has a higher 5 year mortality rate. In one illustration, 10 percent of surgery patients die during treatment, 32 percent will have died one year after surgery, and 66 will have died by five years.
