The cool thing about it is that it's an easy thing to try for yourself [assuming you're not physically unable] and gather your own evidence.

I can't believe these words are about to come off of my fingers, but -- if it works for you, then does it matter what a body of scientific research has to say about it? Because the benefits are at least in part subjective, this is a case where a sample size of one is sufficient.

I asked precisely because it doesn't work for me. As far as I can tell the article is nonsense. But I wouldn't necessarily know whether I was being more or less creative, so actual evidence would trump my personal experience there.

What are the conditions of your experiment? What are you wanting to measure?

Just a measure of creativity?

How about incorporating other factors as mentioned in these comments, some do seem more measurable than others.

Ironically, I think that walking to increase creativity, calmness, clarity of mind, reduce stress, increase fitness, etc is actually purposeful walking. Walking to not get any advantages is more of an interesting phenomena. Why do people do that?
