Humans have always been wired to connect, it’s only the way they connect that has changed over time. With the advent of the internet and the subsequent creation of social media, the way human beings connect underwent a massive transformation. The internet enabled human connections in ways that no one had ever imagined: over large distances and in real time. With the internet, everything became instant.
However, along with the countless benefits of the internet came innumerable drawbacks. With time, the appeal of the internet began to morph into an unhealthy addiction tailored to each individual. This article looks specifically at internet addiction with respect to social media platforms and their attention-economy business model and 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. With its instant messaging, ongoing scrolls, and follow and like features, social media presents itself as an appealing product to the user. But it is these very features which can be detrimental to one’s health. Up until recently, internet addiction was not considered an addiction. But research has led to prove that excessive use of the internet falls into the same criteria as other behavioural and substance addictions and is 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. The amount of engagement on people’s posts in the form of likes, shares, and comments serves as a measure of social validation. This is where the brain chemical dopamine comes in. Dopamine is produced by our brains as a response to beneficial behaviours and motivates us to repeat them.
The feel-good hormone plays a huge role in giving us a sense of pleasure – it is a natural reward system in our body that motivates us to keep doing the things that make us happy. The extent of engagement – and the amount of social validation – on people’s social media accounts serves as a dopamine trigger; the greater the number of likes and followers, the greater the pleasure. The repeated use of social media, combined with the effects of dopamine, causes the platform to become 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. This particular feature has taken away the user’s ability to stop at the end of a page and decide if they want to continue using it or not. Instead, by repopulating their feed every time they reach the end of the page, the platform keeps them scrolling. Social media is addictive by design - the intermittent variable rewards, the ongoing scroll, and the notifications which always hold some hope of a positive social stimulus and dopamine influx.
Various researchers have found a correlation between social media addiction and mental and physical health problems. Connections have been found between an excessive use of social media and depression and anxiety. Not only that, but an addiction to social media and in turn to your phone also causes anxiety associated with misplacing your phone. In his article, Trevor Haynes states that around 73% of people claim to experience this unique form of anxiety.
