Group identity is known to exert a powerful socio-psychological influence on behaviour but to date has been largely explored as a uni-dimensional phenomenon. We consider the role of multiple dimensions of identity, asking what might happen to ingroup and outgroup perceptions and the resulting...

We provide the first investigation of the relationship between self-awareness and dis- honesty in a multi-wave pre-registered experiment with 1,260 subjects. In the first wave we vary the level of awareness of subjects' past dishonesty and explore the impact on behaviour in tasks that include...

In a real effort experiment with repeated competition we find striking differences in how the work effort of men and women responds to previous wins and losses. For women, losing per se is detrimental to productivity, but for men, a loss impacts negatively on productivity only when the prize at...

We aim to understand the role and evolution of beliefs in the indefinitely repeated prisoner's dilemma (IRPD). To do so, we elicit beliefs about the supergame strategies chosen by others. We find that heterogeneity in beliefs and changes in beliefs with experience are central to understanding...

In this paper we investigate how observable cognitive skills influence the development of strategic sophistication. To answer this question, we study experimentally how psychometric measures of theory-of-mind and cognitive ability (or 'fluid intelligence') work together with age to determine the...
