In this paper, we argue that trust is an important aspect of social reality, one that realist social theory has paid little attention to but which clearly resonates with a realist social ontology. Furthermore, the emergence of an interest in trust in specific subject fields such as organization theory indicates the growing significance of issues of trust as market liberalism has developed. As such, the emergence of an interest in trust provides support for Archer's characterisation of late modernity in The Reflexive Imperative (2012) as a period of heterogeneity and greater incongruity. Commenting on this provides an opportunity to discuss the issue of habit in relation to trust and also the importance of the analysis of integration as a means to explain problems of trust. The commentary draws on examples from finance.
