Nature Nurtures Creativity After Four Days of Hiking

I just read about a fascinating new study* that examined 56 people who went on an Outward Bound wilderness expedition. No electronic devices were allowed on the trips. Of the 56 people, 24 took a creativity test before they left for the trip. The other 32 took the test out in the wilderness, on the fourth day of the trip…after four days disconnected from the grid. These 32 people scored 50% higher on the creativity test than the 24 people who hadn’t yet started their trip! The intriguing implication is that those four days enhanced creativity.

The test they used was the Remote Associates Test (RAT). The way it works is that you’re given three words, and your task is to identify a fourth “target word” that is related to all three of those words. For example, an answer to SAME/TENNIS/HEAD would be MATCH (because a match is the same, tennis match, and match head). The test was designed back in the 1960s by Professor Sarnoff Mednick. Mednick designed each triplet so that all three words are related to the target word in a different way; so, to solve the task, your mind has to activate very different conceptual clusters. Hence the name “remote associates.” Mednick argued that people who were better at making these remote associations would be more likely to come up with surprising new ideas.

The test was not timed; you could take as long as you wanted. After four days in the wilderness, the average score was 6.08 triplets (out of ten) were solved. The people who hadn’t left yet scored an average of 4.14 out of ten. That’s a pretty big difference! Kudos to the researchers for getting such strong findings.

There’s a lot we don’t know yet (as the researchers point out).

  1. We don’t know if the higher scores are due to spending time in nature, or are due to simply getting away from work and electronic devices, and taking time off. Psychologists have known for years that vacation enhances creativity, that idle time is a necessary part of the creative process, and that people who work all the time are not going to be at their peak creative potential.
  2. Because the test wasn’t timed, it could be that the people who hadn’t left yet were impatient and were rushing to get everything ready, while the people who took the test out in the wilderness had a lot more time on their hands. Maybe the effects are simply due to the in-hike group spending more time on the test.
  3. The RAT correlates very highly with measures of verbal intelligence, suggesting that it may be more of a verbal skills test than a creativity test per se. (The researchers controlled for age, because older people have higher verbal abilities.)
  4. The RAT requires a person to identify the one correct answer, whereas in many cases, creativity is associated with being able to come up with a broad variety of different answers–what’s known as divergent thinking.
  5. In a large percentage of historical cases, creative insights result from associations of closely related material, not from extremely remote associations. So remote association is clearly not the same thing as creativity, although it seems to be related.
