Psychosocial assistance is a crucial aspect of recent state reparation and human rights restitution policies in post-conflict Colombia. Drawing on the methodological tools offered by Science and Technology Studies (STS), we follow the trajectories of a psychosocial protocol for emotional recovery as a technology of reparation deployed in rural communities between 2013 and 2017. We ethnographically describe how psychological and administrative projects are merged in practice and come to shape practices and emotional self-valuations. Building on Serres concept of betrayal, we reflect on the potential contours of quantifications embedded in psychosocial assistance as opportunities for different forms of reparation to emerge. These forms of reparation coexist in intertwined epistemic practices of psychosocial assistance. We claim that a potentially alternative form of reparation arises despite the predominance of an administrative design mainly concerned with quantification and efficient policy management.
