Social media can hamper teenagers figuring out who they want to be in future

Sunshine Coast: Over recent months, a number of politicians have supported calls to ban social media for children under 16 in Australia. Currently, kids under 13 are not allowed to use social media.

There’s some research that suggests social media can be helpful for certain young people by, for example, connecting them with like-minded peers.

That said, there are a raft of reasons for this proposed change. The most compelling is evidence showing inappropriate screen time and social media use are linked to poor mental health in children and young people, including depression and anxiety.

Overuse or misuse of social media can damage many areas of psychological wellbeing. But, as an expert in adolescent development, I’ve been exploring one that’s not often considered: identity development.

Identity development has long been regarded as the core psychological business of adolescence. You decide who you are, what you want to become, what underlying values you stand for and what you want out of life as you move toward adulthood. But might social media risk thwarting this process?

Developing an identity

Between the ages of about 11 and 15, the human brain becomes increasingly sensitive to attention and feedback from peers. The parts of the brain responsible for developing perspective, judgment, critical thinking and self-control will not fully mature until a person’s early to mid 20s.

Teenagers have always compared themselves to others. They seek validation from peers as they explore their values, develop their personalities and seek to express themselves. But social media have provided a platform for adolescents – particularly those high in FOMO, or fear of missing out – to obsess over how they compare to many more people, including aptly named “influencers”. It can be difficult for a young person to develop a clear sense of self when they’re constantly comparing themselves to and following others.

Similarly, young people are developing many of their opinions based on what they see on social media. An individual’s tendency to conform to other people’s opinions is sometimes called the “bandwagon effect”.

While plenty of social media content can be harmless enough, social media – like the real world – are becoming increasingly political and polarised, with little tolerance for opposing ideas.

Some teens may find themselves latching onto ideologies fed to them via marketing algorithms. And we know young people can become radicalised through social media.

Harry Triandis, a psychology researcher who died in 2019, proposed differences between the “public” and

“private” self that we all embody. Most people can relate to keeping their real opinions or values to themselves while in public or in an unknown group of people.
