Positive Deviance Initiative

This website from the Positive Deviance Initiative (PDI) offers a comprehensive collection of PD resources including case studies, guides, projects and examples.

"Positive Deviance is based on the observation that in every community there are certain individuals or groups whose uncommon behaviors and strategies enable them to find better solutions to problems than their peers, while having access to the same resources and facing similar or worse challenges.

The Positive Deviance approach is an asset-based, problem-solving, and community-driven approach that enables the community to discover these successful behaviors and strategies and develop a plan of action to promote their adoption by all concerned." (Positive Deviance Initiative, 2010)

PDI is affiliated with Tufts University Friendman School of Nutrition Science and Policy, the Positive Deviance Initiative's website
