The chapters in this book show a reflection on some challenges faced by the psychosociological research with a view to the accompaniment, support and even orientation of the processes and psychosocial dynamics of peace building. It is inspired by the set of works included here, but not based on them exclusively or as a priority; rather, it seeks to offer a set of criteria for critical reflection in a unique historical moment by the advocacy opportunities that open up for the improvement of psychosociological research. In turn, it is expected to encourage new reflective practices that contribute to increase the relevance and pertinence of this type of research, to choose fruitful paths both for the definition of research programs and crucial curricular decisions for the advanced training of new generations of professionals who contribute to the coming years to this fundamental challenge of building real and durable peace in Colombia. The book is a contribution to epistemological, methodological, and ethical reflections at a historical and political crucial time for the country, in which unfortunately the desire for peace in rural Colombia is not materialized yet. But, even during vicissitudes and promises for having a stable and lasting peace, psychosociological knowledge becomes meaningful and more relevant.
