I guess ultimately variety is what I like :)
Different people have different levels of ability to filter out background noise. Some people can focus and ignore the outside world so much that you have to wave a hand in front of their face if you need their attention. Other people can't help but parse background conversations and noises all around them.
Noise cancelling headphones level the playing field for people in the second category: It allows them to dial down the distractions and focus like the first group when their environment is fighting hard against it.
Even listening to background music has the same effect for many people. Music, especially familiar music, is not necessarily engaging enough to pull people out of their relaxed states and focus on the music.
However, looking back on it I miss those weeks and months on end of having 6+ hours a day to be outside, working my body, but doing tasks that let my mind wander all over. No doubt those years of daydreaming helped me become the person I am today, and everybody has to grow up at some point, but I do wish I could get more of that back into my daily life. In fact, I think a large part of my current path towards early retirement is just to have that sort of time back.
Part of the reason why I listen to music and scroll my phone is to get some peace from the default mode network.
I don't feel like I would do it as often if my mind didn't insist on being busy all the time.
> The DMN seems to fall into a similar area as meditation (remember when that was all the rage among tech leaders?); the lowered input noise gives the brain time to clear things out.
I am not skilled enough in that department to say anything with certainty. But formal meditation is about intentionally focusing the mind, and the talkative mind or whatever it is called in the buddhist traditions is probably this default mode network. Which is the first obstacle; being able to focus on the meditation object without having your attention hijacked because oh what's for dinner, did I send that email, but what about that other email, oh but I couldn't log in on my phone, oh by the way that phone is also annoying in terms of that related thing, but I should stop using my phone as much anyway what about getting one of those dual SIM cards that I read about on HN.
In my experience, it's probably healthier for the mind to have the DMN active more than someone who can distract themselves all the time do. But to me DMT looks to meditation like sunbathing looks to a day's hike (yeah you're outside for both of these activities but).
What you are describing is likely closest to certain forms of zazen, in which one tries to focus on just one thing or no-thing in order to quiet the mind.
However, just as common, is the various vipassana schools in which one attempts to gain specific insight through specific observation.
In the former, enlightenment comes from still states, in the latter from evolving states.
Then of course there are many visualization and trance traditions, though those are more common the further west you go from SEA.
All that is to say that not all meditation is simple sitting. There are walking meditations, dancing meditations, chanting meditations, visualizations, prayer, etc. And while they differ in technique, they all have the goal of achieving some specific state of mind.
To give you another perspective, I think I suffer from far too much DMN activity. It's very easy for "reflection" to slide into rumination. Increase DMN activity is highly correlated with depression. And I found daily mindfulness meditation to be incredibly helpful at counterbalancing that, spending less time in my head and more time in my embodied experience.
I'm curious about the relationship between mind wandering as exploration leading to insight and mind wandering as rumination. It seems like DMN is more associated with the latter. Its association with meditation likely comes from studies like the below.
Meditation leads to reduced default mode network activity beyond an active task
