Professor Dhami conducted research that was able to predict bail decisions with up to 90% accuracy based upon a simple heuristic that took into account only three non-compensatory cues: whether the prosecution, police, or another court objected to bail (the so-called 'CYA' heuristic). She will discuss the differences between two leading approaches to heuristics: the heuristics-and-biases school that underpins behavioural law and economics, and the fast-and-frugal school associated with Gigerenzer and the ABC Research Group.
