Practical Examples

1. Changing hand hygiene in hospitals

   The book describes how hospitals improved compliance with hand hygiene by making it easier for staff to access hand sanitizer, creating social accountability among colleagues, and tracking outcomes. By addressing personal motivation (explaining the risks), social pressure (colleagues reminding each other), and structural ability (placing sanitizer in easy-to-reach places), significant change was achieved.

2. Reducing HIV/AIDS in Thailand

   Thai health officials changed the behavior of sex workers to curb the spread of HIV/AIDS. Through a mix of motivational campaigns, social peer influence, and structuring incentives for brothel owners, condom use soared, showcasing how combining various sources of influence creates massive societal shifts.

3. Overcoming employee resistance to new technology

   The book details an organization that struggled to get staff to adopt a new software system. By involving enthusiastic early adopters as social influencers, providing easy access to training, and setting up small rewards, adoption rates increased dramatically.

4. Weight loss through community engagement

   A weight loss program succeeded by leveraging group dynamics. Individuals were paired with partners who would support and hold them accountable, while community resources were made accessible. This engagement led to higher success rates than purely individual attempts.

5. Improving school performance

   The authors discuss how a school transformed its culture by creating positive peer pressure among students for academic achievement and establishing clear, supportive structures. Teachers and high-performing students together reinforced new habits, helping others to follow suit.

6. Changing safety habits in construction

   A construction company faced repeated safety violations until managers focused on building a shared commitment among teams. They used daily safety meetings and encouraged crew members to hold each other accountable, resulting in safer behaviors and fewer injuries.

7. Reducing prisoner recidivism

   A prison rehabilitation program incorporated family members and mentors into the process, ensuring prisoners had supportive social networks on release. Programs also made it easier to access jobs and education, combining personal, social, and structural supports for reintegration.
