I know the journalists involved in coverage of the UCS analysis at PRI’s The World and they are competent, fair professionals for whom I have a great deal of respect. But when they interviewed the UCS scientist who did the analysis, they simply never asked about the relative risk number. I made the same mistake all the time back in my reporting days. I just didn’t understand this critical part of risk until I joined the Center for Risk Analysis at the Harvard School of Public Health.
Absolute and relative risk are part of the basic “Who, What, When, Where, Why, How” questions that any story about risk should answer, which most journalists don’t know to ask because few are trained in these specifics. I’ve written about many others in a previous post. I’d have been a better reporter had I known them back then. They’re offered here in the hopes of making journalism a little better, and helping the public make more informed intelligent choices about the risky world in which we live.
