Behavior Science Contributions to Public Policy: an Introduction to the Special Section.

Behavior science has a long history of influencing public policy. Numerous scholars have used behavioral principles in experimental and applied research to examine the potential impact of local, state, and federal policies across socially important problems and goals. The utility of behavior science in public policy continues to flourish, and translational behavioral research will remain a critical component of effective policy development and implementation. The articles in this special section highlight diverse examples of applied research in various areas, such as intellectual disabilities, substance use, and greenhouse gas emissions. In addition, this special section includes findings from experimental research demonstrating the benefits of using demand curve analysis and behavioral procedures such as nudging and boosting to facilitate effective policy change. Together, these articles offer diverse exemplars of behavior science's importance in public policy development and implementation.
