In this episode we talk to Dr Lewis Doyle about unconscious biases, particularly when it comes to marking and assessment. In a groundbreaking study in 2022, Lewis and his team asked 400 teachers to mark the same piece of work but provided different pupil contexts to the teachers before they began. The results were fascinating. Lewis talks about the research and what we can learn from it as both educators and members of wider society. The full report can be found in the British Journal of Educational Psychology here. Lewis is a post-doctoral researcher at the Université de Poitiers and a visiting researcher at the University of Sussex. He has a particular interest in how social psychological processes contribute to educational outcomes and prejudice. He belongs to a group of psychologists calling themselves the School Inclusion Group who carry out research in order to understand and combat educational inequalities.
