A Drake Trying Her Best

Harpies who can't write or type or open most containers with their wings. Werewolves who worry about hurting someone if they get overstimulated at the wrong time. Minotaurs with digestive systems and metabolisms which require grazing throughout the day, not the three big meals humans are used to.

Lamias who have to stay home in the evenings and during cold months to stay warm, otherwise their muscles stop working right and they get stranded. And they're sick of their human friends suggesting they get some kind of tail sweater. It wouldn't help, the problem is that their body doesn't produce enough heat to begin with, and anyways a tail garment would get in the way of their rectilinear locomotion, and there's no way a sweater would survive being walked on in the first place. It feels like they don't actually care about you being stuck at home whenever they go out, they just want to feel like it's not their fault they never see you.

fun fact: for decades children were beaten for speaking welsh in school, even in areas where english was barely spoken, because the government decided in 1847 that the language made people lazy and immoral

fun fact: welsh orthography is actually easy to read if you take your head out of your arse for one minute and learn our alphabet - just like french, or spanish, or korean, because surprise! languages use different spelling systems that are not based on english. novel, i know - and in the 18th century, travelling schools were able to teach people to read and write welsh in a matter of months, so that wales enjoyed a literate majority, a rare thing in europe at the time

Female birds with confusing names.

She got the idea for the study while walking with her advisor at Stanford to discuss her thesis topic, and the paper she eventually published in the Journal of Experimental Psychology in 2014 is sharp enough that it should have ended the seated meeting on the day it came out.

She ran 4 experiments on 176 people. Same person tested twice. Once sitting, once walking. The creativity tasks were the standard ones psychologists have used for decades to measure how good a brain is at generating novel useful ideas.

81% of participants in the first experiment produced more creative ideas while walking than while sitting. In the second experiment, 88%. In the third, 100%. Every single person walked into a more creative version of themselves. On average, people generated 60% more novel useful ideas the moment their legs started moving.

The skeptical question is the obvious one. Maybe it was the fresh air. Maybe it was the scenery passing by. Maybe it was the change of environment doing the work, not the walking itself.

Oppezzo killed every one of those explanations with one experimental decision. She put people on a treadmill facing a blank wall. No scenery. No fresh air. No environmental change. Just legs moving in place while staring at white drywall. The 60% boost held.

Then she ran the experiment that closed the case completely. She took participants outside in two conditions. Half of them walked through a Stanford courtyard. The other half were pushed through the exact same courtyard in a wheelchair. Same outdoor stimulation. Same scenery passing at the same speed. The only difference was whether the legs were moving.

The walkers produced dramatically more novel high-quality ideas than the wheelchair group. The outdoors did almost nothing on its own. The walking did everything.

She also tested the opposite kind of thinking. Convergent thinking. The kind where there is one right answer and you have to narrow down to it. Word puzzles where 3 words share a hidden fourth word that connects them. The seated participants did slightly better on these. Walkers got slightly worse.

Walking is not a general intelligence enhancer. It does one specific thing. It opens up the divergent search inside your brain. The part that generates options. The part that produces unexpected connections. The part that takes a problem and finds five ways into it instead of one.

When you need to converge on the single right answer, sit down. When you need to find the answer in the first place, get up.

The mechanism is now well understood. Walking selectively activates what neuroscientists call the default mode network, the system inside your brain that runs when you are not consciously focused on anything. The DMN is where mind-wandering happens. Where memories cross-reference each other. Where ideas that have been sitting in separate folders inside your head finally bump into each other.

When you sit at a desk and force yourself to concentrate, you suppress the DMN. When you walk at a natural pace, the executive part of your brain gets just busy enough handling the walking that the DMN comes online and starts doing the work that focus was blocking.

The most useful finding in the entire paper is the one almost nobody quotes. The boost did not turn off the moment people stopped walking. Participants who walked first and then sat back down stayed elevated. Their next round of seated creativity work was still significantly better than people who had been sitting the whole time. The rest lingered for at least several minutes after the legs stopped moving.

You do not need to do creative work while walking. You need to walk before the creative work. The brain holds the state.
