I’ve been following Liz Dunn’s happiness research for a while, and now she has co-written a new book, Leave the Lights On: How Joyful Decisions Can Save Our Species (Penguin Random House), about how joy could be the missing weapon in our fight against climate change. Here we sit down for a Q&A about her work.
Jessa: So you and Jiaying Zhao, colleagues at University of British Columbia, have co-written a book. What are your respective research foci and how do they fit together in this collaboration?
Liz: I’m a happiness researcher, and my work focuses on how to optimize our use of resources to maximize happiness. So time, money, technology—I studied AI and smartphones and things like that, and then I got interested in carbon as another one of these. In this case, we don’t want to create too much of it. JZ is one of the world’s leading experts on the behavioural side of climate change. So, how do we change human behaviour in a way that tackles climate change.
Our two specialties are usually on opposite sides of the room—we do not find ourselves next to each other at a cocktail party. But in this case, bringing our almost non-overlapping areas of expertise together has been really powerful. It creates dual lenses so we can find the sweet spot between having a genuine impact on climate change and what makes people happier.
Jessa: One of the concepts in the book that really rang true for me was hedonic adaptation. What people think will make them happy only does up to a point. How does that manifest in our daily lives?
Liz: Yeah, so hedonic adaptation is like the gravity of happiness research—it keeps us from floating away with joy. Whatever happens to us in life, we tend to adapt to it. That’s good because we are pretty good at recovering from bad things, but we also recover from good ones. Somebody from the Renaissance would be blown away by the comforts and conveniences of our daily lives, but we don’t walk around marveling at them. We get used to them.
This is important for thinking about climate change, because it can be tempting to overconsume, ratcheting up our desires and feeling like we need more. The mistake we make is thinking the 10th pair of designer shoes will give us the same level of pleasure the first one did.
