omg omg i am doing some fascinating reading today about the neurobiology of creativity for the playfulness project and it is ALSO helping me understand something that i have been grappling with for a while re: screentime and mindless scrolling on social media. i think a lot about that state of ‘endless scroll,’ where you are glued to your phone and can’t break away from the tumblr/twitter/instagram/facebook loop even though you know the activity you’re engaging in is making you feel increasingly unhappy and restless and dissatisfied.
the common explanation for that feeling is “oh, social media causes you to compare yourself to others, and that makes you unhappy,” but i’ve been thinking for a while that it must go beyond that, because often i’m not even engaging with content that would prompt comparison between my life and someone else’s (or engaging with ads that would make me feel dissatisfied about my body/life/job/whatever). i’ve also been thinking a lot about why it is that when i put my phone away (FAR away, like in my car or in a drawer in my closet) and read a physical book, it’s like something in my brain lights up again, and i find that suddenly my mind is spilling over with thoughts and ideas and hypotheses and plans for the future. i also feel so much happier and more buoyant in the second reading mode, in part because i experience that burst of creative thinking as intensely pleasurable and i begin to engage in a kind of future-thinking that projects me from the mundane present into an exciting, speculative future. in both situations—mindless scrolling and reading a book (or a PDF where i have all social media stuff blocked)—i’m actively reading text on a page. but the experience is so different (and the felt switch between the two states so dramatic) that i know there’s got to be something really different happening in the brain as i read.
the article i’m reading today is about the neurobiological basis of “combinatory play,” which is a form of creative, imaginative thinking that involves combining and recombining seemingly disparate ideas or schemas—in essence, engaging playfully with “what-ifs” and other kinds of speculative thinking (“could this be connected? what happens if i put this idea in conversation with that one?”). it outlines the four different stages of creativity: preparation, incubation, flash of insight (the eureka! or breakthrough moment), and then the methodical testing and validation of the eureka idea. but it focuses especially on the incubation period, which is the phase where you take a break from focused, deliberate work and instead engage in activities like daydreaming, mental wandering, doodling, meditating, sleeping and dreaming, walking, washing dishes, etc., ie activities where you disengage the conscious mind (with its desire for rational solutions and clear answers) and allow the unconscious mind to “play” with different, seemingly illogical ideas or combinations of ideas beneath the surface of conscious thought.
most interestingly: using brain-imaging technology, researchers have been able to demonstrate that in the moments before the flash of insight (the “aha!” moment), activity in your left frontal cortex slows and the visual cortex shuts down completely. according to this article, this slowing/shutdown “suggests that the brain needs to cut out external sensory input to increase connections between the conscious and unconscious mind and to let it play.” those moments directly precede the flash of insight, which occurs “with a burst in the right temporal lobe.”
HERE is why i think that fact is so interesting re: mindless social media scrolling. when i am reading a book, i have significantly more control over the amount of external stimuli entering my brain. i am reading in a linear fashion, but i am also often pausing, looking up from the page, gazing off into the distance to speculate about possible connections, asking myself questions about what i’m reading, testing the information i’m encountering against what i already know or think to be true, etc. in other words, when i am reading a book or from a printed page, my brain moves fluidly between focused attention (the “preparation” stage of creative thinking) and daydreaming or speculative reverie (the incubation stage). the page itself is static, but it’s that stable foundation that allows my mind to wander freely in and out of focused attention, as i alternate between focused reading and a more playful, imaginative, speculative mode of thinking. being able to daydream (a state in which my unconscious or semi-conscious mind weaves in and out of conscious thought) is what allows unexpected new ideas and connections to surface in my mind, and that’s what prompts that exciting rush of creative thinking and future-oriented "what-if” thinking, which in turn triggers those feelings of intense pleasure and delight that lift my mood.
you can’t daydream when reading on a screen, because there is no stable base, and no point at which the brain can momentarily taking in external stimuli can slow or stop (that slowing / shutdown in the left frontal cortext and visual cortex that necessarily precedes a burst of creative insight). on a screen, with the ability to endlessly scroll past content that is designed to hijack your attention and keep your brain continually stimulated. there’s no break in that flow of external stimuli, and no natural stopping points (like the end of a page) that would prompt your mind to rest for a moment or allow you to slip into that state of reverie. we also know that phones are SO GOOD at hacking into our brain’s attention system and trapping us in these extraordinarily addictive & self-reinforcing feedback loops, so we continually seek out more and more stimuli even as addiction makes us increasingly desensitized to the dopamine burst (and thus makes the activity itself less and less pleasurable to engage in).
finding it difficult or impossible to break out of mindless scrolling mode is not a personal failure of willpower. mindless scrolling is a behavior that social media apps are deliberately designed to elicit & repeatedly, unceasingly reinforce, which (because of our neuroplastic brains!) creates these addictive feedback loops we struggle to get out of. and, while comparative thinking might be part of why social media makes us unhappy, i think an even stronger reason might be that mindless scrolling traps us in this state of captivated attention (we can’t look away, bc the addictive loop has become too strongly reinforced) which is also simultaneously a state of continually distracted attention (it’s not sustained focus on a single idea or thread, because the endless scroll means we are continually barraged with stimuli—the emotional content of people’s opinions, ads designed to catch our eye, features of the app like alerts or notifications that continually distract us/break sustained focus, etc etc). hoo boy that is the WORST state of mind to be stuck in, and it’s the one that almost all of us operate in when we’re in that mindless scrolling phase!!!
so we are stuck in mindless scroll, but we are also continually having our equilibrium disrupted by a flow of stimuli designed to trigger strong instinctive or emotional reactions. AND THEN, on top of that, social media apps are essentially designed to eliminate the “incubation” stage—because time spent daydreaming, mental wandering, getting up to do something else, looking off into the distance to engage in imaginative speculation, etc., is time not spent engaging with the app, and therefore is “unprofitable” time that doesn’t serve the core purpose of social media: to keep us hooked on our phones, so that companies can continue harvesting our data (for profit) and/or selling us things. it’s not necessarily that companies are deliberately setting out to kill creative thinking or daydreaming or whatever (i mean... there’s an argument to be made here), but more just that incubation stage thinking isn’t profitable or productive in any way, and thus—in a culture obsessed with maximization and efficiency and productivity—is wasted time that could be harnessed for other ends.
i don’t know if this makes sense!!!! but it is helping me understand that i think my instinct is right: that the kind of reading we do on screens is not the same as the kind of reading we do on paper or just when we are working away from screens/apps/phones, and also that there is probably a neurobiological explanation for why i feel so much happier, more engaged, and able to think fluidly and creatively when i am reading away from my phone vs. when i am reading on my phone or am stuck in mindless scrolling mode.
