The Design Secret to Action Everyone is Missing • Linsey Nancarrow Ep95
Why do people say they want to take climate action — and then get stuck before actually doing it? Behavior designer and user researcher Lindsey Nancarrow joins me to unpack how to find the hidden friction stopping people from taking action. We explore journey mapping, motivation and ability, user interviews, and behavioral techniques for making sustainable actions easier and more compelling.
We also tackle a fascinating tension: should designers give people what they say they want, or create a bold vision and persuade people to come along?

The Secret to Making Communities Fail or Thrive • Giulia May Ep94
Why do so many online communities start with excitement and then fall flat? Community architect Giulia May, who has helped build more than 200 communities – including Hello World Labs – joins me to explore the psychology and social architecture of creating genuine belonging.
We unpack seven principles for building strong communities — including boundaries, initiation, rituals, stories, symbols and subgroups — and why community is fundamentally a feeling, not a platform. We also explore why social media audiences aren't really communities, why forced corporate “belonging” can backfire, and what it actually takes to build a group people genuinely want to be part of.

Beef Climate Labels – Do They Work? Dr Maiken Maier PhD Ep93
What happens when you put a climate impact label on beef in the supermarket? In this episode, we talk with Dr. Maiken Maier, a political scientist and environmental behavior researcher who studies how climate and food policies influence human behavior, social norms, and public opinion.
We dive into her paper, “Increasing the Uptake of Plant-Based Diets: An Analysis of the Impact of a CO₂ Food Label,” and its fascinating findings about the relationship between individual behavior and systems change.
Dr. Maier explains why seemingly modest interventions — like carbon labels, choice architecture, and behavioral design — may be far more powerful than they first appear, particularly when they begin changing what people see as normal, desirable, and politically possible.
