Tracey Brown OBE has been the director of Sense about Science (SaS) since 2002. Under her leadership, the charity has turned the case for sound science and evidence into popular campaigns to urge scientific thinking among the public and the people who answer to them. It has launched important initiatives to expand and protect honest discussions of evidence, including AllTrials, a global campaign for the reporting of all clinical trial outcomes; and the Ask for Evidence campaign, which engages the public in requesting evidence for claims. It has challenged opinions and changed the behaviour of governments, media and corporations in the use of scientific evidence. Tracey leads SaS’ work on the transparency of evidence used by governments in policy, to ensure that the public has access to the same evidence and reasoning as decision-makers. With PERITIA Tracey will provide strategic advice and public engagement insights.
