Great British Intelligence Test Protocol

Abstract The Great British Intelligence Test is a large scale survey of cognition, wellbeing and behaviour in the general population, primarily focused on the UK. The study is run by Adam Hampshire at Imperial College London in association with BBC2 Horizon, being promoted via BBC media. The study is open to anyone to participate and is run via a custom website, the 'Cognitron', which is hosted on the Amazon EC2. The data collected include a sequence of cognitive tests, designed to measure different human cognitive abilities, a questionnaire, probing social, demographic and economic context, dimensions of mental health, online behaviours, personality, psychiatric traits and clinical conditions. Data will be analysed to determine the dimensionality, development and sociodemographic distribution if dimensions of intelligence and wellbeing in the UK population. The study is running throughout 2020, with plans to follow people up longitudinally to see how cognition and wellbeing change, including within the context of the Corvid-19 pandemic.
