Social Norms: A Review

Social norms represent a foundational concept across the social sciences, yet the field suffers from a lack of clarity in terminology and operationalization. This review synthesizes interdisciplinary research—spanning psychology, communication, public health, economics, and law—to delineate how social norms arise and exert influence. The authors highlight the distinction between descriptive norms (what others do) and injunctive norms (what others expect), and contrast these with collective norms (societal-level codes).

The paper addresses the core question: when and why do norms influence behavior? Drawing on the Theory of Planned Behavior and the Theory of Normative Social Behavior, the authors differentiate between spontaneous and deliberative behavioral processing. When individuals act spontaneously, they rely on the most salient norm or attitude of the moment. However, when individuals deliberate, the impact of norms on behavioral intentions is moderated by a complex set of attributes.

The authors propose a new integrated framework that categorizes moderators of normative influence into three domains:

• Behavioral Attributes: Characteristics like cost, privacy, and addictiveness that dictate how easily a behavior can be influenced by social cues.
• Individual Attributes: Factors such as self-efficacy, age, and self-monitoring that determine an individual's susceptibility to peer pressure.
• Contextual Attributes: External environment factors, including time constraints, media exposure, and interpersonal discussion, which change the relative weight of social norms in decision-making.

This framework provides a roadmap for future research, urging scholars to move beyond cross-sectional designs toward experimental methods that can isolate causal mechanisms and account for these various moderating variables.
