Dr Lauren Sullivan

I thank the hon. Member for St Neots and Mid Bedfordshire for securing this important debate. Online harms are systemic, they are scaled, and they are producing real-world consequences, as we have seen. Social media is now the environment in which young people grow up—it is almost universal when children enter secondary school. According to a consultation by the Department for Science, Innovation and Technology, 81% of 10 to 12-year-olds are on social media, and 86% have accounts. The Youth Select Committee also did a study on youth violence and social media back in 2024, and found that 97% of 13 to 17-year-olds were online and that 70% of them see real-world violence online. That is a huge number of statistics, but they demonstrate the fact that social media is now in every young person’s bedroom, in their hand and in their pocket. Professor Sarah-Jayne Blakemore from the University of Cambridge told me that adolescent brains are highly sensitive to the social environment, and the social media companies are probably aware of this. Adolescents’ brains have heightened neuroplasticity, and this will continue until their mid or late 20s. During adolescence, young people are trying to find identity and belonging, and I fear that the tech companies are exploiting this. Where can we see evidence of harm? The National Education Union did a study called “Big Tech’s Little Victims”, in which researchers created fictional accounts and spent half an hour each day on Instagram, TikTok, Snapchat and YouTube. They found that harmful content appeared within three minutes, and often immediately. Young people in my constituency say, “I do not want to see this harmful content anymore,” yet they are still shown it, so what is going on? The hon. Member for St Neots and Mid Bedfordshire mentioned the “Inside the Rage Machine” documentary, which I have seen a number of times. I am absolutely horrified at what the whistleblowers have revealed.
