Agatha Harkness-Smythe Is Determined to Ban Guns in the United

Short Answer

Agatha Harkness-Smythe is determined to ban guns in the United States. This is a controversial topic and social scientists have debated whether the ownership of guns by citizens increases or decreases crime. Agatha could go to the library and research this, using the social science literature. Instead, Agatha just reads the local newspaper and only cuts out articles about robberies in which the "bad guy" used a firearm. Agatha is using a heuristic device that is impeding or obstructing her thinking. Define this heuristic device. What might be a better way for her to examine the issue and avoid this mistake?
