Lotty Brand is interested in the evolution of human behaviour and cognition. Her PhD work investigated the effect of sex differences in confidence and risk-taking on social learning. She also conducted a large scale comparison of statistical analysis techniques to promote a new form of cumulative science. Most recently she has explored the evolution of social hierarchies and prestige-biased social learning. She conducts experiments with members of the wider community as well as students, and is a dedicated science communicator. She believes firmly that all scientific work should be fully transparent, reproducible, and openly available to all.
