The Social Context of Influence & Persuasion
I study how social influence, group dynamics and social interaction shapes and impacts beliefs, behaviours, and judgements of information
Social influence is a part of everyday human life – we make attempts to influence the judgements, beliefs, and opinions of others, we are influenced ourselves and we actively resist influence. In today’s complex information ecosystem where social information is ubiquitous, our judgements and perceptions of information and any influence attempt takes place within a social context. But how does the social nature of information consumption interact with the more cognitive process of judgement formation? In my work I use a range of methods (including experiments, interaction studies and behavioural games) to examine the socio-cognitive mechanisms of trying to influence, being influenced and resisting influence, with a current focus on misinformation. I integrate work from the fields of persuasion, social influence, social identity and more recently, moral cognition. I am particularly interested in studying these influence processes within real social contexts; broadening the scope of current social psychological methods.
We consume information on a daily basis. But how does the cognitive process of judgement formation interact with social influence processes? For example, how does exposure to other people's judgements, our internalised social identities and our direct interaction with other people influence our judgements of information?

Research shows we can psychologically 'inoculate' individuals against persuasive attacks. I study how resistance to persuasion can be induced in the real social world. E.g. can we inoculate individuals against misinformation from highly influential groups?

Competing for Influence
In a world influence is power, one must be strategic in order to win influence over others. Given the social context of competing for influence, what strategies do people use when they attempt to win influence over others, and do they work?
