Loneliness has become such a widespread problem that Silicon Valley billionaires are now highlighting it to market AI companions, with Mark Zuckerberg recently stating “the average American has fewer than three friends”.
This actually echoes what the World Health Organization has called a crisis of social isolation and loneliness. They report that around 25% of older adults are socially isolated and 5%-15% of adolescents are lonely. But a variety of research – including our own – suggests reading may be a much better solution than chatbots.
Human interaction is no doubt hugely important. In a study we published in 2023, we found that it only takes around five close friends for children and adolescents to thrive, giving them better brain structure, cognition, academic performance and mental health.
Having fewer than five close friends may not provide enough social contact. But larger numbers are less likely to be close friends. The dilemma of technology frequently means that despite some people having vast numbers of friends on social media, they are not close friends and so do not provide the social support needed.
