Positive deviance
open-in-new
<p>Positive deviance (PD) is an approach to behavioral and social change. It is based on the idea that, within a community, some individuals engage in unusual behaviors allowing them to solve problems better than others who face similar challenges, despite not having additional resources or knowledge. These individuals are referred to as <i>positive deviants</i>. </p><p>The concept first appeared in nutrition research in the 1970s. Researchers observed that, despite the poverty in a community, some families had well-nourished children. Some suggested using information gathered from these outliers to plan nutrition programs. </p>
