About The Author
Phil Barden is a proven marketer with over 25 years’ experience, including senior and international roles at high profile companies such as Unilever, Diageo and T-Mobile. Fascinated by the insights from decision science and by the value these can bring to marketing, he quit his international brand director post in order to immerse himself in this new field.
He is now one of very few experts to combine a practitioner’s perspective with a profound knowledge of decision science, making him very much in demand among clients and conference organisers alike. In this book he bridges the gap between the world of marketing and decision science, taking the reader on his fascinating journey.
Phil presents on decision science for the IPA Diploma, the APG Planning Skills Diploma and for various international MBA and MSc programmes. He is regularly invited to speak at industry events and to brand owners and their agencies.

author of ‘The Choice Factory’
Decoded contains practical and compelling examples:
“I loved this book. It’s a highly practical book for any modern marketer, packed with clear, compelling examples and also a glorious, enjoyable read for anyone interested in how humans make their choices. My copy is littered with under-linings and notes. Fascinating,
useful, an absolute classic.”









Sophie Devonshire
Chief Executive, The Marketing Society
Decoded is at the leading edge of science:
“Many of us will agree that Marketing is a combination of Science and Art. Science can often give you the springboard you need to take that creative leap. But what if some of the Science you are using is wrong? Phil’s book explains all. He brings Decision Science to life for Marketing. It can be chewy in places, in a good way, but will help you to step up your Marketing impact.”
