A Singular Point of View
If you are a parent standing in a doorway at ten to eleven, watching a face lit blue by a phone, or a teenager who is tired of being told that “social media” is the problem, this one is for you.
You are standing at the end of a street with three front doors. They are all painted a similar bright colour, and every one has a light on inside. From the pavement they look like the same kind of house. You have been told for years that this street is dangerous, so you have stood here with your arms folded, watching the doors and wondering what is going on behind them.
Now walk up and push the first one open. It is a cinema, dark and warm, and nobody in it is speaking. The second is a corner café where your child’s friends turn up without being invited. The third is a stage with a very large audience and no interval. Same street. Three very different evenings.
That is what a survey published by the Pew Research Center in April 2026 found. It asks something more useful than “is social media bad?”. It asks which door, for which teenager, doing what. And if you are reading this because you have a letter from school in your hand, or an assessment date in the diary, or a teenager who has gone quiet and you do not know why, that is the question worth having.
What the survey actually asked
Pew surveyed 1,458 American teenagers aged 13 to 17, together with a parent each, between 25 September and 9 October 2025. The teenagers were recruited through Ipsos’s KnowledgePanel, and the margin of error is plus or minus 3.3 percentage points. (That figure is the width of the fuzz around each number: a result of 50 per cent could really be anywhere from about 47 to 53.) The report looks at TikTok, Instagram and Snapchat side by side, and its central line is blunt: “Within the big universe that is social media, every site is its own unique world for teens.”
That sentence matters because most of the public argument treats the three apps as one object. The teenagers in the survey did not. Ask them about their mental health, their sleep, their friendships or their schoolwork, and the answer changes with the app and with the question.
The headline finding is quieter than you expect
Start with the number that rarely makes a headline. On each of the three platforms, most teenagers said the app neither helps nor hurts their mental health. Of those who did land on “hurts”, the shares sat close together: 9 per cent for TikTok, 9 per cent for Snapchat and 11 per cent for Instagram. TikTok and Snapchat users were slightly more likely to say the app helps than hurts. Instagram users were split, with statistically equal shares on each side. About seven in ten teenagers on each platform described their overall experience as mostly positive, and 3 per cent on each called it mostly negative.
Does that sit oddly beside the way your own house feels at half past eleven on a bad night? It might. Parents in the same survey were far gloomier than their children: about a quarter said social media hurts their teenager’s mental health, and 8 per cent said it helps. You may be one of them, and your worry is not foolish. It is also not the whole picture.
Both sets of observations are real. Your teenager is describing how the app feels from inside a Tuesday afternoon. You are describing the worst of what you have glimpsed over a shoulder. Neither of you is lying, and neither cancels the other out.
Where the three doors really differ
The gaps between platforms show up less in “mental health” as a single bucket and more in particular corners of a teenager’s day. Here are the three corners that stood out.
TikTok: the sleep problem
About four in ten TikTok users (37 per cent) said the app hurts their sleep, compared with roughly a quarter of Snapchat and Instagram users. TikTok users were also the most likely to say they spend too much time on the app, at 28 per cent, and larger shares of them said it hurts their productivity.
Picture the scene. It is gone midnight, the screen is the only light in the room, and the next video has already started before the last one has finished. A feed that decides what comes next has no natural stopping point, so the stop has to come from you, at the hour when your willpower is lowest. Entertainment is the main reason about eight in ten TikTok users give for being there, and entertainment does not end itself.
Snapchat: the friendship app with a sharper edge
Snapchat is the one most tied to people rather than content. About two-thirds of its users say keeping up with friends and family is a major reason they use it, 57 per cent message someone daily, and 44 per cent say it helps their friendships, more than for either rival.
Here is the second true thing, and it sits right beside the first. Roughly three in ten Snapchat users said they had personally been called an offensive name, had a rumour spread about them, or been physically threatened, against about one in five on Instagram and TikTok. A closeness machine is also a place where unkindness has an address. If your child’s best evening and worst evening can both happen in the same app, that is not a contradiction. It is the app.
Instagram: the split verdict
Instagram is the platform where teenagers themselves could not agree whether it helps or hurts. That deserves to be taken seriously rather than smoothed over.
If you are on Instagram, or your teenager is, the useful question is not “is it good or bad?” but “what am I doing on it?”. The same app can be a place to keep up with a friend, or a place to measure yourself against a stranger’s best week. You will usually know which one it was by how you feel when you put the phone down.
What 44,211 diary entries add
A survey records what teenagers say. A diary study records what happens, day by day. A Dutch team (van der Wal, Beyens, Janssen and Valkenburg) followed 479 adolescents for 100 days and collected 44,211 daily diary entries. Their paper, “Diverse platforms, diverse effects”, was published in Current Psychology in January 2026. They tracked well-being, self-esteem and friendship closeness, and asked whether the effect of social media was the same across platforms, or whether one could help while another hurt.
About 60 per cent of the adolescents showed a consistent pattern across the three outcomes. About 13.6 per cent showed contrasting effects: a benefit in one area and a cost in another. In exploratory platform comparisons (early, looser analyses that point towards questions rather than settle them), TikTok, YouTube and Instagram were linked with negative effects, while Snapchat and WhatsApp were linked with positive or null ones.
Set that beside Pew’s Snapchat finding on friendships and the two point the same way. Instagram sits on the negative side in the diaries without being a clear villain in the survey, which fits the split verdict the teenagers gave. Two different methods, one rough shape. The shape is that the platform matters, and so does the teenager.
Before you take this to the kitchen table
Here I want to slow down, because a tidy league table would help no one. These limits are here to protect you from using the findings as a weapon, or from being frightened by them.
Pew’s sample is American. Your teenager in Milton Keynes or Manchester or Mumbai may differ in ways the survey cannot see. It also records what teenagers report about themselves. A teenager who says they feel fine may not be, and one who feels dreadful may be dreadful for reasons that have nothing to do with a phone. Pew’s report does not show that an app caused anything. It shows how the teenagers described their experience.
The diary study is stronger on timing, but its platform comparisons were exploratory, and the effect sizes (the measure of how big a difference is, not just whether one exists) were not confirmed. So please do not read the platform differences as large. If someone tells you that TikTok or Instagram “does” something to your child, they are claiming more than this research can carry.
Both studies measure averages. Your child is not an average.
There is one more limit, and it may matter to you most. Neither study was built to look separately at teenagers who are struggling with anxiety, low mood, ADHD or autism. If you are neurodivergent, or you are parenting someone who is, the things that matter here are sleep, impulse control, the sting of rejection and how easy it is to stop. They may weigh differently for you. That is an extension beyond the evidence, not a finding of it, so treat it as a question to explore rather than an answer.
What you can do this week
The evidence does not tell you to ban an app. It tells you where to look, so pick the one that matches your house.
If the trouble is sleep (most likely TikTok), agree a charging spot outside the bedroom, and set the cut-off at a time your teenager helped choose. A rule they had a hand in is far more likely to survive a bad night than one handed down at the door.
If the trouble is a friendship falling apart (often Snapchat), ask who they message, not how long they message. Then ask what they would do if a message turned nasty, and agree on a screenshot, a block and a word with you, in that order.
If the trouble is how they feel afterwards (often Instagram), ask them to notice, just once, how they feel after twenty minutes of scrolling compared with twenty minutes of messaging a friend. Let them draw the conclusion. It will land harder coming from them.
If you are the teenager, try one week of jotting down three things in your phone’s notes app each time you put it down: the app, the time, and how you feel. Nobody is marking it. You are collecting your own data, and your own data is more convincing than anyone else’s opinion of you.
If your answer is “it makes no difference to me”, believe it, and leave that app alone. About six in ten teenagers in the survey said what they see on these apps makes no difference to how they feel about themselves. You may well be one of them.
If a teenager in your life seems persistently low, withdrawn or hopeless, the platform is not the question to start with. Talk to your GP, or contact Samaritans free on 116 123 at any hour, and keep the conversation about the person rather than the phone.
The street is not one street
The most hopeful thing in this research is also the plainest. You have been asked to judge a thing that was never one thing. There are three apps, three different evenings, and inside each of them a hundred different teenagers having a hundred different nights.
You do not need to win an argument about social media. You need to learn which door your child is walking through, what happens when they get there, and whether they come out feeling better or worse than when they went in. That is a job you can actually do.
So go and ask them, and ask it as a real question. Then listen to the answer for longer than feels comfortable.
