Rosalind Arden is an Assistant Professorial Research Fellow at the Centre for Philosophy of Natural and Social Science at the London School of Economics. She received her PhD from King’s College London in 2010. Her research explores human variation with an emphasis on intelligence. Why are some people smarter than others? What are the consequences of being more, or less, bright? What policies would be practically useful for enhancing the lives of the less bright—a segment of society often overlooked by the cognitive elite? Her email is r.arden@lse.ac.uk.
