Field causality relates to the field/forum division of Forensic Architecture. The field is not a distinct, stand-alone object, nor the neutral background on or against which human action takes place, but a dense fabric of lateral relations, associations, and chains of activity that mediates between the scales and material tendencies of large environments, individuals, and collective action. It overflows any map that seeks to frame it because there are always more connections and relations to be made in excess of its frame. Field causalities challenge contemporary epistemologies because they demand a shift in explanatory models and structures of causation. From such a perspective, the analysis of armed conflict can no longer conform to the model of criminal law that seeks to trace a direct line of causation between the two limit figures of victim and perpetrator. Establishing field causalities requires the examination of force fields and causal ecologies that are nonlinear, diffused, operate simultaneously, and involve multiple agencies and feedback loops. Whereas linear causality focuses on temporal sequenced events, field causality involves the arrangement of causes in a set of spatial relations with one another.
