Study Finds Rule‑Breaking by Others Drives Increased Rule‑Breaking in Participants
750 U.S. participants were tested in an online experiment where 23% initially chose the highest‑reward squares, violating the task rule.
In Brief
- •750 U.S. participants were tested in an online experiment where 23% initially chose the highest‑reward squares, violating the task rule.
- •When participants observed others breaking the rule, especially by selecting squares far to the right, their own rule‑breaking increased, sometimes exceeding the observed violations.
- •The effect was strongest when observers shared the same political affiliation, suggesting partisan alignment amplifies social influence.
- •Computer simulations indicated that a minority of escalating individuals could trigger a collective spiral of rule‑breaking.
- •The study was published in the journal Proceedings of the Royal Society B and highlights limits of abstract experiments for real‑world policy.
Why It Matters
The findings suggest that rule‑breaking can spread through social influence, especially within politically aligned groups, raising concerns for organizational compliance and public policy. Understanding this contagion effect could help design interventions that curb unethical behavior in workplaces, schools, and civic life.
