This week, Grace speaks to Linsey McGoey, professor of sociology at the University of Essex and author of The Unknowers: How Strategic Ignorance Rules the World and No Such Thing as a Free Gift: The Gates Foundation and the Price of Philanthropy.

They discuss how politicians make use of ignorance and uncertainty, the difference between ignorance and deliberate misinformation, and why, if ‘knowledge is power’, ignorance is too.
