It is standard in multiagent settings to assume that agents will adopt Nash equilibrium strategies.  However, studies in experimental economics demonstrate that Nash equilibrium is a poor description of human players' actual behaviour.  In this study, we consider a wide range of widely-studied models from behavioural game theory. For what we believe is the first time, we evaluate each of these models in a meta-analysis, taking as our data set large-scale and publicly-available experimental data from the literature.  We then propose a modified model that we believe is more suitable for practical prediction of human behaviour.
