Bad Apple Effect: How Rule-Breaking Spreads in Groups 2026

The bad apple effect is more than just a saying—new research shows that when people see others breaking rules, they are more likely to do the same, and the effect can snowball into widespread noncompliance. The study, led by Dr. Lucas Molleman from the University of Amsterdam, sheds light on how social context influences our decisions to follow or break rules.

What the Study Found About the Bad Apple Effect

Researchers recruited 750 participants in the US, evenly split between Republicans and Democrats, for an online experiment. Participants completed a task where they had to identify the brightest square in a row to earn a monetary reward. Unbeknownst to them, the researchers manipulated the task to see how exposure to rule-breaking influenced their behavior.

The results were clear: when participants observed others breaking the rules, they were more likely to break the rules themselves. Moreover, the more people saw others exceeding the rule-breaking, the more likely they were to escalate their own noncompliance. This suggests that the bad apple effect is not just about one person corrupting a group, but about a contagion of rule-breaking that can spread rapidly.

Why the Bad Apple Effect Matters

From corporate scandals to political corruption, leaders often blame individual "bad apples" for misconduct. However, this research indicates that the problem may be systemic: the social environment can encourage or discourage rule-breaking. Understanding this dynamic is crucial for organizations seeking to foster ethical cultures.

Dr. Molleman noted that many people believe they make autonomous decisions, especially in individualistic cultures like the Netherlands and the UK. But in reality, we are heavily influenced by what others do. This has significant implications for how we design policies and interventions to promote compliance.

Key Takeaways from the Research

• Social influence is powerful: People are more likely to break rules when they see others doing so, even if they would not have done so otherwise.
• Escalation is common: Exposure to rule-breaking can lead individuals to go beyond what they observed, creating a spiral of noncompliance.
• Context matters: The study highlights the importance of social norms and the environment in shaping behavior.
• Policy implications: Interventions should focus on creating a culture of compliance rather than simply punishing individual rule-breakers.

How the Bad Apple Effect Spreads

The study's design allowed researchers to observe how participants reacted to different levels of rule-breaking by others. They found that when participants saw a high degree of rule-breaking, they were more likely to break rules themselves, and their rule-breaking was more severe. This suggests a tipping point where compliance norms collapse.

The researchers also examined whether political affiliation played a role. Despite the polarized political climate in the US, they found no significant difference between Republicans and Democrats in their susceptibility to the bad apple effect. This indicates that the phenomenon is universal, cutting across ideological lines.

Implications for Workplaces and Organizations

In the workplace, the bad apple effect can have serious consequences. If employees see colleagues cutting corners or violating policies without consequences, they may feel justified in doing the same. Over time, this can erode the entire culture of compliance.

Leaders should be aware that their own behavior sets the tone. If managers turn a blind eye to minor infractions, it can signal that rule-breaking is acceptable. Conversely, consistently enforcing rules and rewarding compliance can help maintain a healthy culture. The background to this story is set out in Business: latest articles.

What to Watch Next

This research opens up several avenues for future study. For instance, how do these dynamics play out in real-world settings like corporations or political institutions? What interventions can effectively counteract the bad apple effect? The researchers suggest that creating a strong culture of compliance and highlighting examples of good behavior could be key.

As Dr. Molleman points out, "We are very much influenced by what others are doing." Recognizing this can help us design better policies and foster environments where rule-following is the norm.
