Matthew C. Nisbet, who has written on science communication, has defined a “knowledge journalist” as a public intellectual who, like Walter Lippmann, David Brooks, Fareed Zakaria, Naomi Klein, Michael Pollan, Thomas Friedman, and Andrew Revkin, sees their role as researching complicated issues of fact or science which most laymen would not have the time or access to information to research themselves, then communicating an accurate and understandable version to the public as a teacher and policy advisor.
