Summary: New research challenges the long-standing image of the solitary drinker and highlights the central role of social drinking in the development and consequences of alcohol use disorder (AUD). Multiple studies show people consistently consume more alcohol in social settings, and the most severe alcohol-related harms—such as interpersonal violence, risky sexual behavior, and fatal traffic incidents—are largely linked to drinking that occurs in groups.
Despite this evidence, much scientific attention has focused on solitary drinking and intrapersonal drivers of addiction, often overlooking social motives, contexts, and group dynamics that can amplify risk. The authors of the reviewed paper argue that understanding drinking as a fundamentally social behavior is essential for designing better prevention, intervention, and public-health responses to alcohol-related harm, and for anticipating similar challenges as other socially integrated substances become more widely accepted.
Key facts:
- Social settings increase consumption: People reliably drink more when they are with others than when they drink alone.
- Major harms are social in nature: Alcohol-related violence, extreme binge episodes, unsafe sexual encounters, and many traffic fatalities predominantly occur in social contexts.
- Research imbalance: Laboratory and theoretical research has focused far more on solitary drinking, despite social drinking driving a large share of population-level harms.

Common images of alcoholism—someone drinking alone at home—miss a significant part of the story.
A review published in Current Directions in Psychological Science argues that social dynamics and social motives deserve far more emphasis in addiction science. The paper, authored by Catharine Fairbairn (University of Illinois Urbana-Champaign) and Dahyeon Kang (University of Washington), synthesizes evidence that social contexts shape when, how much, and why people drink—and how those patterns contribute to disorder and harm.
The authors note that although solitary drinking is an important indicator—especially in severe AUD—social drinking is pervasive and often more consequential for public health. Laboratory and naturalistic studies show that individuals typically consume greater quantities of alcohol in group settings, and that heavy drinkers often find and socialize with others who drink heavily, reinforcing risky patterns.
Cultural portrayals and some scientific theories perpetuate the idea that other people dampen drinking tendencies, suggesting that the presence of others is protective. In reality, group contexts frequently increase consumption and lower inhibitions. Alcohol’s capacity to reduce anxiety and disinhibit behavior can enhance social experiences in the short term, strengthening its role as a tool for social bonding—while simultaneously increasing exposure to harms tied to social interaction.
Evidence links several of the most serious negative outcomes—alcohol-fueled violence, unsafe sex, and episodes of extreme binge drinking—primarily to social drinking situations. Traffic deaths related to alcohol are also commonly rooted in social outings and group-based drinking. Additionally, people who report deriving the most pleasure from drinking in social settings are the same individuals who face elevated risk of developing alcohol-related problems, and some use alcohol as a means to manage strained relationships or social anxiety.
Fairbairn and Kang call attention to the mismatch between the social reality of drinking and the predominance of asocial models in addiction research. They report that basic scientific studies focused on solitary drinking outnumber those addressing social drinking by nearly tenfold, and that leading theories often emphasize intrapersonal mechanisms while underrepresenting social reinforcement processes.
This social perspective on alcohol also has implications for other substances that have shifted from illegal to socially accepted status. As drugs such as cannabis gain broader social integration, similar social dynamics could reshape patterns of use and public-health impact. The authors suggest that alcohol’s deep social embedding offers an early look at legal and clinical dilemmas that may arise with other widely used, socially integrated substances.

Abstract
Social drinking and addiction: A social-cognitive model for understanding alcohol use disorder risk
Historically, much addiction research has prioritized intrapersonal factors and solitary drinking contexts when studying the origins of disordered use. However, a growing body of evidence points to social environments as key contributors to the development of alcohol use disorder. This review outlines four core features of social drinking that are relevant to AUD risk: how common social drinking is, when it typically emerges in development, the negative consequences tied to group consumption, and the reward value that social drinking provides.
The authors present a social-cognitive model describing how alcohol can reinforce social rewards by reducing higher-order cognitive processes that would otherwise limit social pleasure. They summarize empirical studies supporting the role of social contexts in AUD onset and progression, discuss methodological challenges in studying social drinking, and identify directions for future research that better account for social motives and interactions in addiction science.
