## Fear Statistics?

Wired published a quiz regarding "fear factors" and their connection to misleading reasoning. The article claims "the gut...identifies a media-amplified image, story, or statistic as a clear and present danger. The resulting inchoate sense of foreboding causes us to grossly overestimate the danger of highly unlikely threats." Dan Gardner, author of The Science of Fear, tells us to "do the math...and turn off the television."

On these items from the Wired quiz, see how you (or your "gut") does...
