Wolf et al. 1 propose a model to explain the existence of animal personalities, consistent with behavioural differences among individuals in various contexts2, 3, 4—their explanation is counter-intuitive and cogent. However, all models have their limits, and the particular life-history requirements of this one may be unclear. Here we analyse their model and clarify its organismal scope.
