Theorists have argued that the effectiveness of dialogue about equality-related public policy has been limited by a range of factors (e.g. limited representation of minority groups or dominant discourses about ‘equality’ that prevent wider discussion). This study focuses on how we might create public dialogue more in keeping with what people really value around the topic of equality. The study does this by firstly mapping English local authority approaches to engaging ethnic minorities in public policy dialogue. This is followed by a ‘qualitative experiment’ which compares the effects of two popular models of public engagement (‘multiculturalism’ and ‘interculturalism’) on participants’ experiences. The study identifies important conventions of dialogue associated with ‘representative claim-making’ that can hinder critical deliberation of equality-related public policy issues. The study also highlights particular aspects of facilitation practice which appear to improve research participants’ levels of autonomy and the breadth of equality issues discussed through public dialogue.
