Dan Gardner is a columnist and senior writer with the Ottawa Citizen. His journalism has won many awards, including a National Newspaper Award, a Michener Citation of Merit, and Amnesty International’s Media Award.

In 2008, Gardner examined the psychology of risk perception in The Science of Fear (Dutton). A bestseller in the United Kingdom and Canada, published in 11 countries and eight languages, the Daily Telegraph named it one of five “best brain science books” ever written.

In 2011, Gardner’s next book, Future Babble (Dutton) was published. “It’s rare for a book on public affairs to say something genuinely new,” wrote Harvard psychologist Steven Pinker, “but Future Babble is genuinely arresting, and should be required reading for journalists, politicians, academics, and anyone who listens to them.”

Prior to becoming a journalist in 1997, Gardner was senior policy advisor to the Minister of Education of Ontario and social policy advisor to the Premier. He holds a B.A. and M.A. in history from York University and an LL.B. from Osgoode Hall Law School.
