Humans have always been wired to connect. What's changed is the way. With the advent of the internet, and then social media, the way human beings connect underwent a massive transformation: over large distances, in real time, in ways no one had ever imagined. Everything became instant.
The benefits arrived with drawbacks. Over time the appeal morphed into an unhealthy addiction, tailored to each individual. This article looks at internet addiction on social media platforms, at their attention-economy business model and their design.
The instant quality of social media, with the ability to facilitate interactions in real time, has made connections accessible to a degree that can be proven to be harmful. Instant messaging, the ongoing scroll, follows and likes: they make an appealing product. They're also the features that damage health. Until recently, internet addiction wasn't considered an addiction at all. Then research established that excessive use of the internet falls into the same criteria as other behavioural and substance addictions, and it's now accepted as a behavioural addiction.
This behavioural addiction is often spurred by specific design features that shape social media platforms, taking advantage of the human need for social validation and reciprocity. Likes, shares and comments are the measure of social validation. That's where dopamine comes in. Our brains produce it in response to beneficial behaviours. It motivates us to repeat them.
The feel-good hormone gives us a sense of pleasure. It's a natural reward system that keeps us doing what makes us happy. Engagement on a social media account, and the social validation that comes with it, serves as a dopamine trigger: the greater the number of likes and followers, the greater the pleasure. Repeated use plus dopamine turns the platform addictive.
Along with taking advantage of the human need for social validation and desire to connect, social media platforms have also removed natural stopping cues by introducing the ongoing scroll in their designs. You lose the natural stopping point at the end of a page. The platform repopulates the feed and the scrolling carries on. Social media is addictive by design: the intermittent variable rewards, the ongoing scroll, the notifications that always hold some hope of a positive social stimulus and dopamine influx.
Researchers have found a correlation between social media addiction and mental and physical health problems. Excessive use has been connected to depression and anxiety. Addiction to the phone itself brings anxiety about misplacing it. In his article, Trevor Haynes puts it at around 73% of people.
