This article synthesises the findings from two studies on the operationalisation of intersectionality in Scotland: one in equality policy and NGOs, and the other in domestic abuse policy-making. Drawing upon Ashlee Christoffersen's framework of applied concepts of intersectionality, this article analyses the competing and contradictory ways that intersectionality is institutionalised in Scottish policy and practice. It highlights the contestations and debates that arise when actors with varying understandings, agendas, and levels of political will attempt to apply intersectionality. We argue that dominant approaches to applying intersectionality in Scottish equality and domestic abuse policymaking are additive and superficial, a consequence of power inequalities shaping who has access to policymaking processes and institutions. Beyond the Scottish case, the article highlights key lessons concerning how to operationalise intersectionality in policy and practice in ways that are truer to its original conceptualisation in Black feminism.
