The benefits of marriage

Agree or disagree? I'm not sure if it's really self-control, or an unwillingness to be subject to negative consequences by a spouse that you can't hide such behavior from for long (eg berating, arguments, threats of discontinued intimacy or divorce). Peer pressure can work for positive results too...

The benefits of marriage
Marriage can potentially help reduce crime by enabling people to develop greater self-control, according to a new study examining changes in marital status, self-control and marijuana use between late adolescence and early adulthood.
September 26, 2011
The study by Dr. Walter Forrest, Senior Lecturer in Criminology at Monash University and Associate Professor Carter Hay, from Florida State University found that young marijuana users who went on to marry were less likely to have continued using the drug than those who remained single. The study was based on analyses of the 1997 National Longitudinal Survey of Youth, a nationally-representative survey of American adolescents and young adults.

Many criminologists have assumed that marriage helps reduce crime because married people feel they have more to lose by committing crime or because married people tend to think about how their spouses might react when deciding how to act in different situations. Those who are married also spend less time in situations that might lead to crime or in the company of friends who might encourage them to commit crime.

“Most people seem to develop greater self-control as they get older, but married people seem to experience the greatest increases, independently of the age at which they married,” said Dr. Forrest.

“Those increases in self-control, in part, explain why people are less likely to be involved in crime when they are married than when they are single.”
