Business Marketer Dave Stevens talks to a legend in marketing circles in a wide- ranging interview. Rory Sutherland is the Vice Chairman of Ogilvy in the UK and co-founder of that business’s behavioural science practice. He has variously been President of the IPA, Chair of Judges for the Direct Jury at Cannes, and speaker at TED Global. He is the author of two books The Wiki Man and Alchemy: the Surprising Power of Ideas which don’t Make Sense. And he’s behind the LinkedIn B2B Institute’s recent paper The Objectivity Trap.
