The idea is that because most people don't know a great deal about the science of global warming, they rely on "heuristics"&mdash;or mental shortcuts&mdash;to make up their minds about what to believe. "Trust" (or the lack thereof) is a classic shortcut, allowing one to quickly determine who's right and who's wrong in a seemingly complex and data-laden debate. Or as the paper put it: "The public's low level of knowledge and the media's conflicting, often value-laden messages about global warming lead people to use heuristics to make sense of this complex issue."
