Epistemic status: Unwieldy articulation of what I take to be a commonplace.
The economy of attention is zero-sum or indeed negative-sum: if you’re paying attention to me you can’t also pay attention to your work. Attention is a scarce resource, and easily damaged, which is why it commands such high prices. Moreover, it’s now widely understood that there are ‘transaction costs’ when moving attention around, so that looking at a single article for twelve seconds has infinitely more value than looking at six articles for two seconds apiece. The myth of ‘continuous partial attention’ refers to specific circumstances requiring only low-yield passive monitoring — say, checking on the stove to see if the pasta’s done (yes or no).
The economy of immersion, so to speak, is positive-sum: deep immersion in one activity generates not only a sense of fulfillment but a supply of usable energy which can be turned to other activity: more life, as the blessing goes. Sustained immersive activity (writing, biking, sex, cooking) not only generates important negative feedback — pulling you back to the activity itself — but builds excess capacity. A daylong hike can begin to restore fragmented attention, a fifteen-minute freewrite realigns your internal verbal mechanism, good sex this morning will leave you with naughty thoughts all day which seem to enliven as much as (or more than) they distract; in each case, the energetic/attentional output has a long wavelength, a gentle contour, so that you might not notice how much it has reduced the effect of local (mental) noise. But three or four such waves will effectively drown out high-frequency cognitive bother.
Immersion has a tidal or oceanic character. There’s a reason we talk about ‘flow’ states, ‘waves’ of calm, etc. Peaceful vs panicked breaths. This is obvious.
Sane people know that fifteen minutes of exercise will give you an hour of deeper creative productivity — i.e. ‘I don’t have time’ is straightforwardly false for nearly all cases. The same goes for any joyful (≠ pleasurable in many cases) immersive activity.
Immersion is generative, tourism is usually costly. Ask your Spanish teacher.
