Some examples of his talks:
Dancing with Systems
We want to change behavior, but often run into something bigger: the system itself. The culture, rules, interests, and routines that keep everything the same. Tom shows how to set that very system in motion — not by pushing harder, but by playing smartly with its dynamics. What roles do beliefs, rewards, and unwritten rules play in system behavior, and how can you leverage them to trigger change from within? How do you get not just people, but entire systems moving — organizations, teams, or communities stuck in their own habits and beliefs? From influencing individuals to understanding systems as living organisms. Small interventions can create big shifts — if you know when to push, where to slow down, and how to use the dynamics instead of fighting them.
How Do Design Principles Influence Our Behavior, Thinking, and Emotions?
How do malicious, clever, or simply unaware designers steer our behavior through the way choices are presented to us? From how a space is arranged to how reward structures are designed within organizations — everything triggers expected and unexpected actions. In a series of talks on this subject, Tom reveals how behavioral designers shape our actions, thoughts, and emotions — and why it’s time to start worrying about it.
