The Psychology of Choosing Not to Drink

For most of modern history, the decision not to drink alcohol was framed as an absence — a lack of participation in normal social life, a refusal, a denial. Teetotallers were caricatured as joyless, puritanical, or socially anxious. But a growing body of psychological research suggests that choosing not to drink is not a deficit but a trait — one associated with higher internal locus of control, lower dispositional compliance, and greater psychological autonomy. [Rotter (1966)]

Julian Rotter's concept of locus of control, introduced in 1966, distinguishes between individuals who believe their outcomes are determined by their own actions (internal locus) and those who believe outcomes are determined by external forces (external locus). Multiple studies have found that non-drinkers score significantly higher on measures of internal locus of control than moderate or heavy drinkers. They are less likely to conform to peer pressure, less susceptible to marketing messages, and more likely to make health decisions based on personal values rather than social norms. [Rotter (1966)]

This finding challenges the dominant narrative that non-drinkers are missing out or somehow deficient. Instead, it suggests that the decision to abstain from a widely available, heavily marketed, culturally embedded substance requires a level of conscious reflection and autonomous choice that social drinking does not. The drinker who reaches for a glass because everyone else is doing so is acting in accordance with external cues. The non-drinker who declines is actively resisting them. Psychological reactance — the motivational state aroused when personal freedoms are threatened — may also play a role, particularly among individuals who resent being told what to do by alcohol marketing or social pressure.

The data on the sober curious movement supports this interpretation. According to the Institute of Alcohol Studies, 24 percent of UK adults now describe themselves as teetotal — the highest figure since records began. Among 18- to 24-year-olds, the figure rises to 36 percent. Alcohol Change UK reports that one in five non-drinkers cite "not wanting to lose control" as their primary reason, a response that reflects a deliberate preference for autonomous self-regulation.

The rise of the sober curious movement — a loose cultural phenomenon rather than an organised campaign — has given non-drinkers a positive identity that previously did not exist. Sobriety is no longer framed as recovery from addiction but as an aspirational lifestyle choice associated with health, clarity, and authenticity. BBC News reported in early 2026 that alcohol-free events, bars, and social clubs have grown fivefold in the UK since 2022, driven primarily by under-35s who see alcohol as optional rather than central to social life.

This cultural shift has significant implications for public health. If non-drinking is associated with higher autonomy and internal control, then policies that support and normalise abstinence — alcohol-free options in pubs, social events that do not centre on drinking, public health messaging that destigmatises refusal — may be more effective than traditional harm-reduction messaging aimed at drinkers.
