Backe explains that notifications, especially push ones that come through to your phone without having to actually log in to your account or open an app, have the same effect on the brain as slot machine wins. He explains: “When you use slot machines, you eventually get something back in return, even if it’s less than what you put in. This gives you the hope and excitement that you’re ‘winning’. Social media works in the same way, in the sense that each time a notification pops-up informing us of a ‘like’ or ‘retweet’, we’re given positive reinforcement in the form of a social reward.”

Slot machines give players a huge dopamine hit when they win. The sound of the coins dropping out of the machine has a similar impact on the brain chemical serotonin as the sound of a notification alert. It triggers that same chemical reaction, which is why we are geared to respond to them in the same way.
Essentially, social media is swapping coin rewards in casino games for emotional rewards on their own platforms. When playing slots, you win back small amounts of money intermittently and the unpredictable positive reinforcement hides the fact you are really losing. In the same way you might actually dislike social media in general, when you are rewarded with likes and comments, it is harder to quit using the apps for fear of missing out. The easier you make it for a user to access these social rewards, for example through push notifications, the more likely they are to engage with the platform.

While social media platforms didn't necessarily set out with the intention of making users addicted, they have done so inadvertently. “The ‘like’ button on Facebook was designed to increase engagement on the platform, but, instead, it resulted in taking over the social reward system in users’ brains," Backe tells us. "This meant that a new phenomenon called 'the attention economy' cultivated where people crave validation as much as they crave a monetary reward from a slot machine.”
You don’t have to look much further than the #L4L hashtag, where users 'like' a random post in exchange for another. It may be superficial, but it’s a means of achieving social validation.
