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?

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.

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.

Communications strategist and author Nicholas Bruneau shares lessons from his book, Engage with Impact: 5 Steps to Transform Your Digital Communications for Social Impact. Drawing on interviews with leading environmental communicators and years of experience advising mission-driven organizations, Nicholas breaks down the biggest challenges around turning awareness into hands-on engagement.

We explore why NGOs often expect people to jump straight from seeing a campaign to taking meaningful action, and how adopting an agile, audience-centered communication strategy can dramatically improve results.

If you've wondered why your campaign isn't converting, this conversation offers a roadmap for lasting participation.

Environmental psychologist Dr. Joel Ginn discusses his recent research paper on plant-based defaults and how subtle changes to choice architecture can significantly reduce meat consumption and encourage more sustainable behaviors.

His research challenges one of the biggest assumptions in behavior change: do we need to persuade people to eat less meat, or can we achieve the same outcome and more by simply changing the food environment?

For restaurant menus, government forms, and climate campaigns: discover one of the most powerful—and underused—tools for designing real-world behavior change.

In this episode, you’ll learn how to:

• Design default choices that make sustainable actions the easiest option.
• Reduce cognitive load by simplifying choices instead of overwhelming people with information.
• Use menus, forms, websites, and enrollment processes to increase participation in green programs.
• Structure campaigns using choice architecture rather than relying on education alone.
• Apply behavioral science to create lasting shifts in everyday environmental decisions.

Behavioral scientist Dr. Anirudh Tiwathia, Director of Behavioral Science at Rare, shares groundbreaking research measuring how climate storylines in popular entertainment—from Don't Look Up, Grey's Anatomy, and Sex and the City—shape public attitudes, social norms, and support for climate action.

We explore why documentaries and facts alone often fail to change behavior, how Hollywood can "prime" audiences for action, why behavior change happens through a sequence of touchpoints rather than a single campaign, and what sustainability professionals can learn from entertainment media.

In this episode you'll learn:

• Why behavior change is rarely triggered by a single campaign—and what to do instead.

• How TV shows and movies can prepare audiences for future climate action, even if they don't create immediate behavior change.

• How to design a sequence of engagement touchpoints that gradually move people toward action.

• The psychological barriers that must be overcome before people adopt new behaviors.

• How entertainment media can shift social norms and create the political conditions for larger systems change.

Why did this psychology technique get more sign-ups than offering people to save money? In this episode, environmental psychologist Dr. Mona Bielig shares the results of a real-world field experiment that tested one of the simplest—and most effective—behaviour change techniques available.

Working with social housing residents in Belgium, her team discovered that a small change in how an energy-saving technology was described dramatically increased adoption, even though the technology was already free and saved people money.

Katie and Mona unpack the hidden psychology behind social norms, why information and financial incentives are often not enough to change behaviour, and how understanding people's real barriers can transform the effectiveness of climate campaigns.

Have you ever dismissed eco badges, climate stickers, or "Save the Earth" T-shirts as empty virtue signaling? Think again.

In this episode, environmental psychologist Dr. Tabea Hoffmann reveals why visible public signals are far more powerful than they appear. Drawing on her latest research paper, she explains how these seemingly small acts shape social norms, influence what people believe is acceptable and expected, and help build momentum for larger-scale climate action. It's called The Social Feedback Loop.

Discover the hidden psychology behind public signaling and why one of the simplest, lowest-cost interventions may also be one of the most effective tools for growing environmental movements and increasing support for systems change.
