The headline study behind the awe walk comes from a respected source. Titled "Big smile, small self: Awe walks promote prosocial positive emotions in older adults," it was published in the journal Emotion, first appearing online in September 2020. The work was led by researchers at the University of California, San Francisco (UCSF) Memory and Aging Center and the Global Brain Health Institute, in collaboration with Keltner at UC Berkeley.
Inside the UCSF Awe Walk Study
The design was refreshingly low-tech. Researchers enrolled a group of older adults from a long-running healthy aging study, and 52 healthy participants completed the eight-week program by taking at least one 15-minute outdoor walk each week. People were randomly sorted into two groups. One group received a brief explanation of awe and was invited to notice things that might spark it on their walks. The other group was simply asked to take walks as they normally would.
Over those eight weeks, the people in the awe group reported a growing sense of awe and more daily positive emotion, including prosocial feelings like compassion, gratitude, and admiration, along with a drop in daily distress compared with the control group. The fact that awe itself increased with practice is part of what makes this encouraging — it suggests wonder is less a matter of luck and more a skill you can build.
The study focused on healthy older adults, many recruited because loneliness and emotional wellbeing become especially important with age. That makes it a strong starting point, but it also means the findings are most directly about this group rather than every population.
What the Selfies Revealed
One detail from the study has a way of sticking with people. Participants were asked to take selfies during their walks, and over the weeks, researchers noticed a quiet visual shift. People in the awe group gradually made themselves physically smaller in the frame, letting the landscape take up more of the picture, while their smiles grew measurably more intense. The change in how they saw the world showed up in how they pointed the camera.
The lead author connects that image to a core idea. "One of the key features of awe is that it promotes what we call 'small self,' a healthy sense of proportion between your own self and the bigger picture of the world around you," said Virginia E. Sturm, PhD, an associate professor of neurology and of psychiatry at the UCSF Weill Institute for Neurosciences. The shrinking selfie is the small self, caught on camera.
What the Study Did Not Show
Being honest about the limits is part of what makes this practice trustworthy. The effects were, in the researchers' own framing, relatively moderate — small, incremental, and building gradually over time rather than arriving as a dramatic transformation. Each awe walk nudged daily positive emotion up a little, in something like a dose-response pattern, but no single walk rewrote anyone's mood.
Just as importantly, the study did not find significant changes in standardized measures of anxiety, depression, or life satisfaction over the eight weeks in either group. In other words, awe walks gently shifted people's everyday emotional texture, but this trial did not show them treating clinical symptoms. That distinction matters, and it is one most coverage of the awe walk skips right over.
