“End-point bias” is a well-known psychological tendency to interpret a recent short-term fluctuation as a reversal of a long-term trend. When scientists reported a significant increase in the extent of Arctic sea ice in 2013, a FoxNews.com story evoked end-point bias by contrasting the historically low previous year with the presumed recovery and de-emphasizing the clear downward trend since 1979.
A study by Annenberg Public Policy Center (APPC) distinguished research fellow Bruce Hardy and APPC director Kathleen Hall Jamieson finds that even liberals and moderates who are suspicious of the accuracy of Fox News can be influenced by such decontextualized information. CONT.
