David Allison is a human values researcher, bestselling author, and founder of the research company behind the Valuegraphics Database, the world’s first global inventory of core human values. Over the past decade, he has transformed one million surveys conducted in 152 languages across 180 countries into a practical framework for understanding what drives human behaviour. He calls this framework What Matters Most — in other words, what people value. Through his keynotes, Allison helps organizations better understand what matters most to the customers, employees, members, and donors they need to reach.
The Valuegraphics Database is used by organizations including Google, PayPal, Amazon, and the United Nations Foundation. Allison’s research shows that when organizations give people more of what matters most to them, engagement increases by 40 percent, trust and loyalty by 20 percent, and financial commitment by 12 percent.
Allison opens every keynote with a live, real-time diagnostic that reveals the values driving the behaviour of people in the room. From there, he shows audiences how to apply the same approach within their own organizations, giving them a data-informed way to better understand the people they need to reach.
His books include We Are All the Same Age Now and The Death of Demographics, which was named one of the year’s top ten leadership books by Inc. His third book, The Values Map: Discover What Drives You and How to Move Others, will be published by Wiley in January 2027.
His work on valuegraphics is also taught alongside demographics and psychographics in marketing textbooks used in more than 100 countries. In 2025, he received the Silver Apple Award for Innovation, an honour that has been presented only four times in 100 years.
