How a Few Individuals Brought about a Cultural Cusp: From a Mexican Mural Program to a Movement

Significant cultural change often results from the interlocking behavior of a few individuals. The phenomenon is nonreplicable because a considerable portion of the major players' interactions are nonrecurring and driven by unique circumstances. Yet, these interactions can be analyzed from a behavioral science perspective. As an example, I describe how five individuals made possible the cultural cusp that created an unprecedented social revolution through public murals in Mexico. I analyze how their repertoires complemented each other, the circumstances that brought them together, and the values that united them. Their unique interactions coalesced with recurring interlocking behavioral contingencies that created the movement. The example could shed light on the understanding of other cultural phenomenon with similar properties.
