ABSTRACT
Many of the challenges facing humanity could be resolved by population-wide changes in individual behavior patterns. Intolerance of others considered different from ourselves within and between nations, wealth inequalities, health-threatening poverty, crime, the health and social damage caused by drug abuse, and the increasing concentration of CO 2 threatening the human habitat are all generated and sustained by more or less widespread patterns of potentially modifiable behavior. In this chapter, we focus on how individual behavior patterns can be changed to prevent illness and sustain health, but the underlying principles of intervention design and evaluation have much wider application.
