This feels so pretentious. People can keep it closed or open for whatever reason they want, and it has no correlation to how they solve problems or learn.

Personally, I like it open when I'm feeling social and in a good mood, and close it when it's noisy outside and/or I need to hunker down and focus for a bit without distractions. That doesn't say anything about understanding or solving problems, other than 'sometimes people need quiet to focus' which is not a very shocking revelation.
