The Social Norms Lexicon is useful resource from the Passages Project for researchers, practitioners, policy makers, and donors that draws from a number of widely used resources to provide simple, clear definitions and examples for frequently used social norms terms.  With the goal of fostering a common language around social norms, the Social Norms Lexicon facilitates shared understanding of social norms terms, thereby improving communication and collaboration across stakeholders from different regions and disciplines to advance social norms research and practice.
