SMU Behavioural Sciences Institute Director Professor David Chan delivered a talk and was on a panel with Minister of State Sim Ann, moderated by Professor Tommy Koh, at the Singapore Perspectives conference organised by the Institute of Policy Studies. Professor Chan explained the need to study new ways to address group differences. He noted that an individual has multiple social identities and it goes beyond narrowly-defined groups such as class, race or language. He said that it is possible to have intervention or policies that avoid or manage identity clashes between people or groups by activating different identities, and that this is a new way of thinking about co-existence of multiple identities in a dynamic way.
