In 2014, Stanford researchers Marily Oppezzo and Daniel Schwartz ran an experiment that quietly became one of the most cited papers in creativity research. They asked participants to generate novel uses for everyday objects (a classic divergent-thinking test) while sitting, walking on a treadmill, or walking outside.
What they found
Walking, in either condition, produced an average 60% increase in creative output compared to sitting. The effect was so robust that 100% of participants in the indoor walking condition generated at least one more creative idea than when sitting. The boost persisted for a short window after the walk ended.
Why this works
The mechanism is still debated, but the leading theories converge on two ideas. Walking increases prefrontal blood flow and BDNF release, which support associative thinking. It also reduces the cognitive load that comes with sustained focus, letting the default-mode network make unexpected connections.
How to actually use this
- Hold one-on-ones as walking meetings whenever weather and topic allow.
- Take stuck problems on a 15-minute walk before reopening the doc.
- Carry a voice memo app, not a notebook. You will catch more ideas.
