#2 - Encouraging Seeking Without Fulfillment

We want things and when we get them, we enjoy them. However, the brain circuit involved in wanting (mesolimbic dopaminergic system) is much more powerful than the brain circuit involved in enjoyment. The feeling of wanting something can be so strong that even when we find what we want, we don’t get much satisfaction. Sometimes, the wanting networks in the brain become hypersensitive and we get addicted: endless loops of seeking. In addiction, what we want becomes dissociated from what we enjoy. 

Technology often capitalizes on the potency of wanting, providing endless possibilities for seeking but few experiences that satiate. We might find fleeting pleasure, but no enduring satisfaction. Our “tolerance” increases, and we need more to achieve the same effects. The result: we keep clicking and scrolling, mindlessly consuming content, often with minimal oversight from cognitive control regions of the brain. Ultimately, this behavior depletes us, but feeds engagement-based business models.

‍#3 - Forcing Us to Multitask

The capacity of our brains to process information is staggering: billions of neurons have trillions of “conversations” among each other, activating large networks of our brains to navigate the demands of living. Yet our brains’ resources are limited: we are highly distractible creatures and the quality of our attention can easily be compromised. When we frequently switch attention from one task to another, we experience an “attention residue” whereby thoughts about the previous task interfere with giving full attention to the current task. 

Social media inspires this multitasking, which affects our cognitive control, emotions, and, ultimately, our brains. These platforms keep us continuously engaged, triggering repetitive, automated behavior and weakening activation in the prefrontal cognitive control regions of our brains. A National Academy of Sciences working group found that media multitasking among youth is associated with poorer memory, increased impulsivity, and changes in brain function. This evidence encourages us to be cautious with our brains and avoid continuously flooding all of our brains’ channels.

‍#4 - Weaponizing Fear and Anxiety

Two decades ago, researchers wrote an influential paper where they famously concluded: bad is stronger than good. Negative information garners more attention and shapes emotion and behavior more powerfully than positive information. Our brains process negatively valenced information – especially fear-related stimuli – more quickly and thoroughly than they process positive information. This makes evolutionary sense: in the pursuit of survival, the potential loss involved in a singular experience of threat outweighs the gain involved in singular experience of pleasure. It is unsurprising that social media content generating fear, anger, and disgust spreads much faster than positive content. We marinate in this negativity and it propels deeper engagement. Fear and outrage become the norm and can erode our sense of goodness and shared humanity. ‍‍

#5 - Encouraging Constant Social Comparison

As social animals, we naturally evaluate our own worth by comparing ourselves to others. The medial prefrontal cortex in our brains prioritizes information about ourselves. Self-esteem involves an ongoing process of affirming ourselves and fighting off threats to self-worth. 

Our habit of measuring ourselves against others sometimes inspires us to achieve more, but comparisons more commonly lead to negative emotions: envy, shame, anxiety, or conceit. Social media dramatically escalates the scope and stakes of our comparisons. It floods us with highly curated images featuring people in select moments showing only what they want you to see. Influencers establish standards of excellence and we tether our self-image to those ideals. Our ‘likes’ – which activate powerful reward circuits in the brain – become a commentary on the deepest part of ourselves. This is a recipe for compulsive comparison, self-doubt, and egocentric melodrama. ‍‍

‍#6 - Telling Us Whatever We Want to Believe

Our brains are exquisitely sensitive to social exclusion. Social rejection hurts in the same way physical pain can hurt. Consequently, we experience strong pressure to conform. Software algorithms learn about our preferences, customizing and curating the information we receive. In our online bubbles, deviating from the party line carries serious social risk. When we become invested in a particular view, we celebrate supportive information and dismiss contradictory information, a phenomenon known as “confirmation bias.” Taken to an extreme, members of different segments of society find themselves subscribing to different versions of reality. When algorithms tell us what we want to believe, we become more polarized and lose a sense of ourselves as a cohesive social group with shared understanding.
