"I experience tremendous guilt," admitted Chamath Palihapitiya, former Vice President of User Growth at Facebook, to an audience of Stanford students. He was responding to a question most his involvement in exploiting consumer behavior. "The short-term, dopamine-driven feedback loops that we take created are destroying how club works," he explained. In Palihapitiya'due south talk, he highlighted something nearly of the states know only few really capeesh: smartphones and the social media platforms they support are turning us into bona fide addicts. While it'due south piece of cake to dismiss this claim equally hyperbole, platforms like Facebook, Snapchat, and Instagram leverage the very same neural circuitry used past slot machines and cocaine to go on u.s.a. using their products as much as possible. Taking a closer look at the underlying science may requite yous break the next time you feel your pocket fizz.

Never Alone

If you lot've always misplaced your phone, you may have experienced a balmy state of panic until it'south been plant. About 73% of people claim to feel this unique flavor of feet, which makes sense when you consider that adults in the Usa spend an average of 2-four hours per twenty-four hour period borer, typing, and swiping on their devices—that adds up to over 2,600 daily touches. About of us have become and then intimately entwined with our digital lives that we sometimes feel our phones vibrating in our pockets when they aren't even at that place.

While at that place is null inherently addictive about smartphones themselves, the true drivers of our attachments to these devices are the hyper-social environments they provide. Thanks to the likes of Facebook, Snapchat, Instagram, and others, smartphones let us to bear immense social environments in our pockets through every waking moment of our lives. Though humans accept evolved to be social—a key feature to our success as a species—the social structures in which we thrive tend to contain about 150 individuals. This number is orders of magnitude smaller than the 2 billion potential connections we carry effectually in our pockets today. There is no doubt that smartphones provide immense benefit to social club, just their cost is becoming more than and more apparent. Studies are beginning to bear witness links between smartphone usage and increased levels of feet and depression, poor sleep quality, and increased risk of automobile injury or expiry. Many of u.s.a. wish we spent less time on our phones but notice it incredibly difficult to disconnect. Why are our smartphones so hard to ignore?

The Levers in Our Brains – Dopamine and social advantage

Dopamine is a chemic produced by our brains that plays a starring role in motivating behavior. It gets released when we have a bite of delicious nutrient, when we have sex, subsequently we practice, and, importantly, when nosotros take successful social interactions. In an evolutionary context, it rewards the states for benign behaviors and motivates us to repeat them.

The human brain contains iv major dopamine "pathways," or connections betwixt different parts of the brain that act equally highways for chemic letters called neurotransmitters. Each pathway has its own associated cognitive and motor (movement) processes. Iii of these pathways—the mesocortical, mesolimbic, and nigrostriatal pathways—are considered our "reward pathways" and have been shown to exist dysfunctional in well-nigh cases of addiction. They are responsible for the release of dopamine in various parts of the brain, which shapes the action of those areas. The quaternary, the tuberoinfundibular pathway, regulates the release of a hormone chosen prolactin that is required for milk production.

Effigy 1: Three dopamine pathways and their related cognitive processes. Most of your dopamine is generated deep in the midbrain, and it is released in many different areas beyond the encephalon. These areas are largely responsible for behaviors associated with learning, habit formation, and habit.

While the reward pathways ( Effigy ane ) are distinct in their anatomical arrangement, all three become active when anticipating or experiencing rewarding events. In particular, they reinforce the association between a particular stimulus or sequence of behaviors and the experience-good reward that follows. Every time a response to a stimulus results in a reward, these associations become stronger through a process called long-term potentiation. This process strengthens often used connections between encephalon cells called neurons by increasing the intensity at which they respond to particular stimuli.

Although not every bit intense every bit hit of cocaine, positive social stimuli volition similarly upshot in a release of dopamine, reinforcing whatever behavior preceded it. Cerebral neuroscientists have shown that rewarding social stimuli—laughing faces, positive recognition past our peers, letters from loved ones—activate the same dopaminergic reward pathways. Smartphones have provided us with a most unlimited supply of social stimuli, both positive and negative. Every notification, whether it's a text message, a "similar" on Instagram, or a Facebook notification, has the potential to be a positive social stimulus and dopamine influx.

The Hands that Pull – Reward prediction errors and variable reward schedules

Because virtually social media platforms are free, they rely on revenue from advertisers to make a profit. This organisation works for everyone involved at first glance, but it has created an artillery race for your attending and time. Ultimately, the winners of this arms race volition be those who best utilise their product to exploit the features of the brain's reward systems.

Reward prediction errors

Enquiry in reward learning and habit take recently focused on a characteristic of our dopamine neurons called reward prediction error (RPE) encoding. These prediction errors serve equally dopamine-mediated feedback signals in our brains ( Figure 2 ). This neurological feature is something casino owners take used to their advantage for years. If you've ever played slots, you'll have experienced the intense anticipation while those wheels are turning—the moments between the lever pull and the event provide time for our dopamine neurons to increase their activity, creating a rewarding feeling but by playing the game. It would be no fun otherwise. Merely as negative outcomes accumulate, the loss of dopamine action encourages u.s.a. to disengage. Thus, a balance betwixt positive and negative outcomes must exist maintained in order to go along our brains engaged.

Figure 2: Reward prediction and subsequent dopamine activity. Unexpected rewards increment the activeness of dopamine neurons, acting as positive feedback signals for the brain regions associated with the preceding behavior. As learning takes place, the timing of activity will shift until information technology occurs upon the cue alone, with the expected reward having no boosted effect. And should the expected advantage not be received, dopamine activity drops, sending a negative feedback signal to the relevant parts of the brain, weakening the positive association.

Variable advantage schedules

How practise social media apps have advantage of this dopamine-driven learning strategy? Similar to slot machines, many apps implement a advantage pattern optimized to continue you engaged as much as possible. Variable reward schedules were introduced by psychologist B.F. Skinner in the 1930's. In his experiments, he plant that mice respond virtually frequently to reward-associated stimuli when the advantage was administered after a varying number of responses, precluding the animal's power to predict when they would be rewarded. Humans are no different; if we perceive a reward to be delivered at random, and if checking for the advantage comes at trivial price, we end upwards checking habitually (e.g. gambling addiction). If you pay attention, yous might find yourself checking your phone at the slightest feeling of boredom, purely out of addiction. Programmers work very difficult behind the screens to go on you doing exactly that.

The Battle for Your Time

If you've been a Facebook user for more than a few years, you lot've probably noticed that the site has been expanding its criteria for notifications. When you lot first join Facebook, your notification heart revolves around the initial set up of connections y'all brand, creating that crucial link between notification and social reward. But as you use Facebook more and brainstorm interacting with diverse groups, events, and artists, that notification eye will also become more than active. After a while, yous'll exist able to open the app at whatsoever fourth dimension and reasonably await to be rewarded. When paired with the low cost of checking your telephone, you have a pretty strong incentive to check in whenever you can.

Other examples highlight a more deliberate try to monopolize your time. Consider Instagram's implementation of a variable-ratio reward schedule. As explained in this 60 Minutes interview, Instagram'southward notification algorithms volition sometimes withhold "likes" on your photos to deliver them in larger bursts. Then when you make your post, you may be disappointed to find less responses than you expected, just to receive them in a larger agglomeration later on on. Your dopamine centers have been primed by those initial negative outcomes to respond robustly to the sudden influx of social appraisal. This apply of a variable reward schedule takes advantage of our dopamine-driven want for social validation, and information technology optimizes the balance of negative and positive feedback signals until we've become habitual users.

Question Your Habits

Smartphones and social media apps aren't going anywhere anytime soon, so it is upward to united states of america as the users to decide how much of our time we desire to dedicate to them. Unless the advert-based profit model changes, companies like Facebook will keep to practise everything they can to keep your eyes glued to the screen as often every bit possible. And by using algorithms to leverage our dopamine-driven reward circuitry, they stack the cards—and our brains—against us. Simply if you want to spend less time on your telephone, there are a multifariousness strategies to achieve success. Doing things similar disabling your notifications for social media apps and keeping your display in black and white will reduce your telephone's ability to catch and concord your attention. Higher up all, mindful use of the technology is the best tool you have. So the next time you pick up your telephone to bank check Facebook, you might ask yourself, "Is this really worth my fourth dimension?"
