科学家表示,禁止青少年使用社交媒体缺乏证据支持,且存在风险。
Social media bans for teenagers lack evidence and pose risks, scientists say

在《发展心理学前沿》(*Frontiers in Developmental Psychology*)最近的一篇社论中,临床心理学家莫妮卡·内夫·林德(Monika Neff Lind)博士对全球范围内禁止16岁以下青少年使用社交媒体的趋势提出了质疑。支持者认为这些禁令有助于改善心理健康,但内夫·林德博士断言,目前尚无严谨的科学证据支持这一观点。 她的研究团队回顾了现有的关于社交媒体限制的实验,发现没有任何研究涉及16岁以下的参与者。此外,关于成年人的研究结果也不一致,许多研究显示其对福祉的影响微乎其微,甚至有负面影响。 内夫·林德博士警告称,此类禁令可能会适得其反,引发青少年的逆反心理,通过侵入性的年龄验证技术侵犯隐私,并切断青少年获取必要组织沟通渠道的途径。由于许多年轻人可能会绕过这些限制,禁令最终消除的可能并非社交平台本身,而是家长提供的保护性监管。 内夫·林德博士敦促各国政府在缺乏数据的情况下,不要急于推行政策,而应针对这些禁令的实际影响进行全面且协作的评估。她认为,决策者正面临“盲目行动并造成破坏”的风险,并建议改善数字环境——而非简单粗暴地禁止——才是应对青少年心理健康危机的更有效途径。

本次 Hacker News 的讨论围绕一份近期报告展开,该报告指出禁止青少年使用社交媒体缺乏有力的科学依据,且可能带来意想不到的负面影响。 支持该报告的人士强调了政府强制禁令带来的重大伦理问题,特别是年龄验证技术引发的隐私风险、针对边缘化青少年的歧视性执法隐患,以及学校和青少年组织所依赖的重要数字通讯工具可能丧失的问题。 相反,怀疑论者认为,社交媒体的危害因企业利益而被淡化。批评人士指出,以追求参与度为导向的成瘾性设计就是心理操纵的证据,并将当前形势比作历史上对烟草或石棉的治理抗争。这些评论者认为,鉴于家长往往力不从心,且不能指望企业自觉监管,政府的法规介入是必要的。 这场辩论依然两极分化:一些参与者因缺乏因果数据而反对出台广泛的立法,另一些人则主张政府应紧急干预,以保护儿童免受以营利为目的的平台所带来的固有风险。许多用户还强调,诸如家长所面临的经济压力等更深层次的社会问题,才是这场危机的根源。

Bans on teenagers’ social media use are gathering pace worldwide. Their proponents claim that social media bans will improve young people’s mental health, but what evidence supports these claims? In their new Frontiers in Developmental Psychology article, Dr Monika Neff Lind and her co-authors argue that there is no solid scientific evidence behind these bans, and reason to believe they could backfire. In this guest editorial, Neff Lind explains why she and her colleagues doubt that social media bans will work, and how bans should be evaluated to determine whether they have any positive effects.

By Monika Neff Lind, PhD

In December 2025, Australia banned young people under 16 from having social media accounts. France, Greece, Spain, Denmark, Malaysia, Norway, India, Egypt, Canada, Türkiye, and the United Kingdom are hot on their heels. French president Emmanuel Macron said, “Banning social media for those under 15: this is what scientists recommend.” American senator Brian Schatz, author of the Kids Off Social Media Act, said, “Studies have revealed that when children and teens reduce or eliminate exposure to social media for longer than a month, their mental health benefits.” Proponents of youth social media bans claim that we have strong scientific evidence showing that bans will improve teenagers’ wellbeing.

As a clinical psychologist and parent, I would be thrilled if this were true, but it is not. We do not know how social media bans will affect youth because we have never studied that question. Let me explain.

Searching for evidence

When we want to test claims like ‘banning social media improves youth wellbeing’, scientific experiments are one of our most powerful tools to figure out what is causing something to happen. In experiments testing the effects of social media restriction on wellbeing, we randomly assign people to at least two groups: one quits using social media for a period of time and the other is the control or comparison group, which continues to use social media as usual. Given the strength of ban proponents’ claims, my co-authors and I were curious to know how strong the experimental evidence supporting their position was. In our new study, we collected and reviewed all of the experiments that have tested whether social media restriction improves wellbeing, and we were shocked by what we found.

Not a single social media restriction experiment has included people under the age of 16. We do not know how social media bans will affect the young people being targeted by them because we have never tested this with them!

To be fair, sometimes strong evidence in adults warrants making the leap to apply the same conclusions to teenagers. But even that leap is not justified here. The experiments with adults show weak, null, and mixed effects, with 40% of experimental studies showing harmful effects (eg, decreased life satisfaction and increased loneliness) or no effects of social media restriction. So even when adults are told repeatedly that social media is bad for their mental health and that giving it up will help, we find, on average, few to no benefits.

Unintended consequences?

There is also good reason to believe that bans may backfire. First, enforcing a youth social media ban raises major ethical concerns. Enforcement efforts invade people’s privacy and are likely to hurt marginalized people more. For example, the technology that determines age based on selfie uploads makes more mistakes with young faces and people of color. Banned youth may also miss out on important resources and communications provided via social media, as schools, clubs, and most other youth-serving organizations use social media as a main form of communication.

What happens when enforcement efforts fail? Many young people will circumvent bans by creating fraudulent ‘adult’ accounts or lurking anonymously. They will retain access to social media without any of the benefits of parental controls or content filters enabled by youth accounts. The vast majority of young people oppose youth social media bans, and teens are well known for their defiance of top-down edicts that disregard their needs. Expect more conflict between teens and caregivers, not less.

To recap, we don’t know how social media bans will affect teens, and the bans may backfire. Yet the bans are still happening! Like other policies that consume resources, political capital, and time, it is imperative for governments to evaluate these actions by funding comprehensive assessments of the bans’ impacts.

What next?

The first step in measuring the impact of these bans is to determine if the bans actually change teenagers’ social media habits. Three months in, Australian authorities reported that close to 70% of social media accounts owned by people under 16 remained active.

Second, we need a careful and well-resourced plan to measure both positive well-being and mental health problems from multiple sources, including self-report, caregiver report, and objective behavioral data, to get a full picture of whether and how altered social media use affects youth.

Third, we need creative approaches to capture the real-world impacts of the bans, since true experiments are not possible and effects may be at the community as well as the individual level. For example, we could randomly assign a subset of youth (eg within a certain region) to delayed enactment of the ban. Whatever approach is taken, governments must collaborate with diverse stakeholders – including young people – to rigorously and openly evaluate potential impacts. Rushed or improvised assessment will leave room for politicization and motivated reasoning.

Big Tech has become infamous for ‘moving fast and breaking things’. Policymakers rushing to enact these bans risk repeating Big Tech’s mistakes and compounding the problems the bans are trying to solve. We cannot ban our way out of a youth mental health crisis. Rather than take things away, we should make things better.
