Abstract

The decisions that humans and animals make define their existence. Some decisions are carefully considered, such as choosing a mate; other decisions must be quick, such as deciding whether a rustle in the bushes is a companion or a predator. In many situations like the latter one, decisions are based on imperfect sensory evidence accumulated over a second or two, so that the brain can average out background 'noise'. Although we do impressively well in making these quick decisions, we make many mistakes. Writing in Science, Brunton et al.1 combined computational modelling with behavioural studies of rat and human decision-making to uncover where the errors in simple decision-making creep in.
