Caroline Fiennes is Director of Giving Evidence, a consultancy and campaign promoting evidence-based giving. Giving Evidence advises many donors about understanding and improving their effectiveness. It has a major study underway of how philanthropy can learn from medicine about using evidence, and supports foundations to disclose tales of challenges as well as success: it's hard to make data-driven decisions if lots of data are missing.
Caroline often speaks publicly and writes in the press, and authored 'It Ain't What You Give', an acclaimed book about effective giving. She serves on boards of The Cochrane Collaboration, the Center for Effective Philanthropy and Charity Navigator, and was an award-winning charity CEO.
