I’ve been collecting other analogues of open mode vs. closed mode. I have a strong suspicion that they’re all facets of the same underlying mental stance.
In brainstorming, generating vs. filtering seem to be open and closed, respectively.
In writing, drafting vs. editing.
The believing game vs. the doubting game.
In social settings, vulnerability vs. filtered interaction
In improv acting, “yes and” vs. rejecting ideas
And maybe even relaxed vs. tensed muscles, though this seems more tenuous to me. On the other hand, dancing in closed mode is just kind of embarrassing, while dancing in open mode is really fun.
This keeps coming up in creative and performance settings, and they often need reinforcement and extra explanation. The analogue of open mode makes new ideas more possible, and the analogue of closed mode makes checking ideas more possible. Both are generally valuable, but they seem to interfere with each other. (For instance, in brainstorming, it’s always tempting to generate and critically assess ideas at the same time, but it just doesn’t work!)
Newbies at almost anything are tempted to stay in the closed mode, because they’re afraid that they’re going to mess up somehow; but only in open mode are you likely to make new mistakes to learn from. Improvisation is nearly impossible in closed mode.
In all of these cases, I find the analogue of open mode to be much more fun, though often hard to maintain.
