How perception of peer behaviour influences escape decision making: The role of individual differences

Abstract

Escape behaviour of humans during emergencies in crowded environments is typically assumed to follow a so-called “panic” model in which the population is made up of homogeneous individuals whose decisions are primarily governed by their follow-the-majority instinct. Here, we have revisited this assumption using experimental observations, econometric modelling and computer simulation with a particular focus on the role and the nature of individual differences in perception of peer behaviour. The results suggested that, in choosing their escape strategies, individuals perceive the decisions of their peers differently depending on the level of available information (i.e. choice ambiguity).
