It is a pleasure to serve under your chairmanship, Mr Stringer. The debate so far has done a really good job of summarising lots of the reasons why I chose to bring forward a private Member’s Bill earlier last year to address some of the issues relating to the addictive features of smartphones and social media, such as the impacts on sleep, mental health and educational attainment. There are also increasing concerns about conspiracy theories and their ability to spread, particularly among young children. Today, I will focus specifically on the evidence, because I think that that is where the political debate is moving and where there seems to be the greatest disagreement—particularly on whether we have enough evidence now to act with confidence or whether we should pause and wait for further evidence. There are three ways I think about this issue. The first is that, in 2012, something happened not just here, but around the western world and beyond, and it was specifically to do with teenage mental health and levels of anxiety and depression among our young people. That global event coincided with the rise in access to smartphones and social media and high-speed internet. There is no other plausible hypothesis that I have heard or come across—I would welcome interventions from colleagues here today—to explain that global phenomenon; there is no coherent alternative hypothesis. So when we think about the evidence that we require to act in this country, we should think carefully about whether we are looking at developed, different hypotheses for why this problem has grown. The second element is the precautionary principle, which links to another point that was made. The tech industry in particular is very effective at casting doubt over findings from studies. Over the years, the burden of proof and of evidence has fallen on those like the many Members present and the petitioners. It has been for them to establish beyond reasonable doubt that there is a causal link between the use of smartphones and social media and the harms that it may cause. It is important in this debate, and in others, to balance where that evidence should be brought from. Surely we should place a burden of proof on those rolling out technology and platforms that are gobbling up huge amounts of children’s and young people’s time. At a fairly conservative estimate, the average 12-year-old is spending the equivalent of a part-time job every week on their smartphone. That must have some effect on how they might otherwise have used their time, the development of their brains, and their relationships with other people while they are on those platforms.
