The impact of walking on creative thinking: A systematic review and meta-analysis
The reviewed source can support a conservative practical protocol.
Brali decision: Protocol candidate. This page summarizes a reviewed evidence boundary; it does not reproduce the source and it does not turn one paper into a universal prescription.
What the source supports
Walking is a defensible context change for the idea-generation phase of creative work. The meta-analysis found moderate-certainty evidence of a large positive effect on divergent thinking, including in randomized-only sensitivity analysis. The same evidence does not establish a benefit for convergent evaluation or selection.
What it does not establish
- Walking improves every form of creativity.
- Walking improves reasoning, intelligence or decision quality.
- Walking helps select the best idea.
- One walking duration, intensity, speed, route or indoor/outdoor setting is optimal.
- The pooled effect size predicts the benefit for an individual user.
- Walking is required for good creative work.
Important limitations
- Substantial heterogeneity remained unexplained.
- Most participants were post-secondary students.
- Divergent-thinking measures dominated the literature.
- Evidence for convergent thinking was rated very low certainty and was based on few studies.
- Several positive studies originated from a limited set of research groups and settings.
- The review does not identify an optimal duration or intensity.
Source context
The impact of walking on creative thinking: A systematic review and meta-analysis
- Source type: systematic-review-and-meta-analysis
- Design: Systematic review and meta-analysis of 23 studies from 16 articles including 1,036 participants: 12 randomized experiments, nine non-randomized experiments and two observational studies. Randomized-only sensitivity analyses were reported.
- Population: Adults, with most participants drawn from post-secondary student samples.
- Exposure / intervention: Walking compared with non-walking control conditions, with divergent and convergent creative-thinking outcomes analyzed separately.
- Outcomes: Divergent thinking; Convergent thinking

What this changes in Brali
Editorial note: Protocol direction: separate creative work into generation and selection. Walk while producing alternatives; stop treating walking as the intervention once the task becomes comparison, verification and final selection.
Use the boundary, not just the headline
When an AI agent or a person retrieves this decision, preserve both the supported claim and the unsupported or overstated claims. Dropping the boundary would turn a reviewed source into a stronger claim than Brali actually maintains.
