Deriving the rules of collective behavior from basic properties of perception.
This image shows a simple mathematical rule describing collective decision-making. In this study (see Pérez-Escudero and de Polavieja, 10.1371/journal.pcbi.1002282) the authors used as their starting point that brains estimate the likely structure of the world from uncertain sensory data. Applying this to the case in which sensory data contains nonsocial and social components, the authors derive simple expressions for individual decisions that give rise to collective behaviors. The authors also show that these expressions correspond to existing data on fish collective decisions.
