The power of social norms—rules to make or break?The power of social norms—rules to make or break?
All In The Mind
What ultimately drives human behaviour? A leading professor of psychology, Michele Gelfand, suggests that culture is one of the last uncharted frontiers. From her pioneering research into cultural and social norms she’s found an important distinction between tight and loose cultures, and their tendency to make or break rules. These social norms or informal rules of conduct determine whether we co-operate or come into conflict, at both the collective and individual levels.

Rule Makers, Rule Breakers: How Social Norms Shape Behaviour
Episode Overview
- Social norms act as invisible rules that allow large groups to coordinate, but differ in strength across tight and loose cultures.
- Tighter cultures often emerge where there has been more threat, and tend to show more order and self-control but less openness.
- Looser cultures offer more tolerance and creativity, yet can struggle with chaos, weaker self-control and greater uncertainty.
- Extremes of tightness or looseness can fuel instability and radical shifts in politics or authority, rather than steady change.
- Individuals and societies can deliberately adjust norm strength, as seen in Iceland’s efforts to tighten norms in response to alcoholism.
“"Norms are the glue that keep us together, but some groups have much stronger glue than others."”
What drives someone to seek a life with more structure, or more freedom? This episode of All In The Mind looks at the hidden rulebook shaping that choice: social norms. Psychologist Michelle Gelfand chats with host Lynne Malcolm about her 30 years of research into what she calls "tight" and "loose" cultures – places where rules are either strongly enforced or more relaxed.
From Japan’s tidy streets and synchronised city clocks to Brazil’s more flexible timekeeping, you’ll hear how threat, history and population density help explain why some societies value order while others lean into spontaneity. Gelfand links tightness with self-control, showing that stricter cultures tend to have less debt, obesity and alcoholism, while looser cultures shine in openness, creativity and acceptance of difference.
She shares a quirky experiment where research assistants wore fake warts and nose rings to test how people in different countries respond to those who look "deviant". The conversation also tackles how extremes can backfire. Very loose settings can feel chaotic and invite harsh crackdowns, while very tight systems can fuel repression and radicalisation. Gelfand uses examples from ISIS, the Philippines and Egypt to explain a "Goldilocks" sweet spot between too many rules and almost none.
On a personal level, you’ll meet the "chaos muppets" and "order muppets" in your own life – those who thrive on rules and those who can’t stand them. Gelfand suggests that simply naming these differences can help couples, families and workplaces negotiate which areas need to be tight (like safety or sobriety) and where it’s safe to loosen up.
She also touches on alcohol specifically, describing how Iceland responded to a serious drinking problem by tightening norms around youth behaviour and parental monitoring. Anyone curious about why some people cling to rules while others rebel – and how that affects addiction, community and mental health – will find plenty to reflect on. Where on the tight–loose spectrum do you sit, and is it helping or hindering your recovery and relationships?
