FIGURE 1—

Theoretical changes in community latrine proportion as a function of transitivity at 3 different levels of community latrine proportion.

Note. When the overall latrine ownership proportion in a community is low, then the effect of transitivity is to act as a normative constraint on overall latrine ownership within the community. When latrine ownership is medium, then the effect of transitivity is null. At high levels of latrine ownership, transitivity then acts as a catalyst toward adoption, and community-level latrine ownership will increase.
