Although diffuse thinking comes in the guise of a break from focus, our minds are still working. Often, it’s only after we switch away from this mode that we realize our brains were indeed working for us. Moving into diffuse mode can be a very brief phenomenon, such as when we briefly stare into the distance before returning to work.~ Shane Parrish from, https://fs.blog/focused-diffuse-thinking/
It is a most interesting mode of thinking. Even after protracted wondering, it’s not clear to me what exactly is the list of things necessary to intentionally slip into the mode of thinking. So I’ll start with some things that will prevent me, every time: Being exhausted or even very-tired will prevent my diffuse thinking. Because settling in, physically and mentally, is also how I go to sleep. Being overly energetic will prevent my diffuse thinking. It’s as if the mind is the driver atop the elephant, and the elephant must be in the mood to follow, not in the mood to frolic or smash.
