Social media and kids: what the science does and doesn’t say
Scientists disagree about how much social media harms kids on average. They broadly agree on where to be careful. OurDot is built around those points of agreement.
The evidence that social media causes the rise in youth anxiety and depression is still debated. Health bodies like the US Surgeon General and the American Psychological Association recommend caution. Researchers like Candice Odgers, Amy Orben and Andrew Przybylski find the average links are small. Jonathan Haidt and Jean Twenge argue the harm is real and large. Nearly everyone agrees that sleep, heavy use, comparison features and contact from strangers deserve care, and that close family connection helps.
What the research found
The precautionary view
In 2023 the US Surgeon General said there is "not enough evidence that social media is safe" for kids, and pointed to a study finding that teens using social media more than 3 hours a day faced double the risk of poor mental-health outcomes. The American Psychological Association's 2023 advisory and 2024 follow-up recommend limiting features like endless scroll and public metrics, and protecting sleep.
The "small effects" view
Across 355,358 adolescents, Orben and Przybylski (2019) found digital technology use explained at most 0.4% of the variation in wellbeing. Odgers wrote in Nature (2024) that the associations are mostly "small and mixed" and that reverse causation, struggling kids using more social media, is likely. A meta-analysis of experiments that reduced social media use by Chris Ferguson (2024) found an effect close to zero.
The "real and large" view
Haidt, Rausch and Twenge argue that the shift to phone-based childhood caused much of the decline in youth mental health. Re-analyzing Ferguson's experiments, they reported a small benefit from cutting back (d = 0.15 overall; 0.26 for depression and anxiety). Ferguson acknowledged some errors.
A middle ground
The World Happiness Report 2026 concluded that heavy use is "an important part of the explanation" for falling youth wellbeing in English-speaking countries and Western Europe, but not the whole story. It found that feeling you belong at school had roughly six times the effect on life satisfaction that social media use did.
Where experts disagree
The disagreement is mostly about how big and how causal the effects are, not about whether any risk exists. It's also hard to study single features, since most studies measure "screen time" or "social media use" in general.
How this shaped OurDot
We didn't wait for the debate to settle. We designed around the points where the cautious and the skeptical camps overlap: protect sleep, avoid endless feeds and public like counts, keep strangers out, and make it easy to stay close to family.
What we don't claim
- That OurDot improves mental health or prevents depression or anxiety. We have no outcome data.
- That social media causes the teen mental-health crisis. That question is still debated.
