Understanding the evolution of human behaviour and societies is complex, and to achieve more significant perspectives it is often necessary to transcend the limits of our datasets, experiments, and theories. The aim of the PATH is to foster collaborative work to break the current state of knowledge and allow the emergence of new perspectives and conclusions, as can be done in scientific synthesis. The PATH participants will meet, virtually and in Faro, to reflect and produce results that transcend their individual talents, skills, and expertise. Together, they will produce outstanding outputs, typically under the form of a special issue and a white paper, and/or co-authored referenced syntheses. Applications to third-party, outreach actions, policy briefings are also valued outputs.
