Indigenization in psychology leads to modes of theorizing based within local knowledge communities and defined in terms of culturally relevant criteria. The present study offers a conceptualization of the social psychology of science in terms of complexity theory. Dominance by a single paradigm (such as a Western world view) leads to a single-peaked landscape where advances in knowledge are judged using only the criteria of that paradigm. The most effective form of working is incremental step-by-step research; but this ignores the historical context of the indigenous community and runs the risk of promoting a kind of psychology that is irrelevant to its values and priorities. Indigenization is presented as a complexification of the knowledge community building on a diversity of world views, leading to a rugged, multiple-peaked knowledge landscape. Four features of working on rugged landscapes are examined: path dependence, showing the importance of history for shaping the direction of research; fostering research progress through seeding of multiple starting points; the benefits of locally dense networks within knowledge communities; and the role of policy-makers in tuning knowledge landscapes. Examples are drawn from the development of indigenous psychology within a number of countries.
