Liane is using human experiments as well as modelling approaches, to develop a coherent theory of the process by which culture evolves.  She aims to bring forward a theoretical framework for cultural evolution that is as sound as out theoretical framework for biological evolution, and apply it to the tasks of reconstructing our past, exploring possible futures, and furthering human wellbeing.  A major component of this interdisciplinary enterprise involves explicating the mechanisms underlying creativity and how the complexity and creativity of the human mind came about.
