This animation and briefing on unconscious bias adapted by Professor Uta Frith DBE FBA FMedSci FRS introduce the key concepts and current academic research around unconscious bias with the aim of alerting Royal Society selection and appointment panel members to potential biases that can arise when making judgments or decisions. They form part of the Society’s efforts to ensure that all those who serve on selection panels are aware of differences in how candidates may present themselves, how to recognise bias in oneself and others, how to recognise inappropriate advocacy or unreasoned judgement.
