Our study aims to gauge public opinion of claims made around ‘Brexit’ (i.e., Great Britain’s departure from the European Union). In this study, several such claims have been fact-checked to determine their truthfulness and accuracy. Purpose was to test the interactive effects of conclusion strength/framing, explanation structure, and information source detail availability on the efficacy of fact-checks on politically contentious claims. Further, to assess if reactions to fact-checks were moderated by political orientation and/or (mis)match between fact-check stance and preferred political outcome
