Abstract
A formal complaint was lodged with the British Psychological Society in 1995 that alleged serious scientific misconduct by Hans J Eysenck. The complaint referred to research into the links between personality traits and the causes, prevention and treatment of cancer and heart disease. Using a framework of institutional logics, we criticise the Society's decision not to hear this complaint at a full disciplinary hearing. We urge the BPS to investigate this complaint afresh. We also support calls for the establishment of an independent National Research Integrity Ombudsperson to deal more effectively with allegations of research misconduct.
