Resolved: The United States should prohibit social media accounts for people under 16.

Australia now bans social media accounts for children under 16. Should the United States do the same?

Background

In 2023, the U.S. Surgeon General issued an advisory on social media and youth mental health. It reported that up to 95% of teens use social media, that teens average about 3.5 hours a day, and that those spending more than three hours a day faced double the risk of poor mental health outcomes such as depression and anxiety symptoms. It said “we do not yet have enough evidence to determine if social media use is sufficiently safe” for young people, while also noting benefits such as connection for isolated youth. [1]

In late November 2024, Australia passed a law making platforms such as TikTok, Instagram, Snapchat, Facebook, Reddit and X liable for fines of up to A$50 million if they systematically fail to keep children under 16 off their services, with the rule taking effect about a year later. The law relies on “age assurance” methods rather than requiring uploaded IDs. In the U.S., several states have passed age-related social media laws, and courts have blocked some of them, including Utah’s 2023 law, after challenges from the tech industry group NetChoice. [2]

Where the facts themselves are disputed

Does social media cause poorer mental health in teens?

  • Many studies find links between heavy use and depression and anxiety, and some experiments in which people cut back show improvements.
  • Other researchers say most studies show correlation, not cause, the average effects are small, and some teens benefit from online communities.

Key terms

Age verification / age assurance
Ways of checking or estimating a user’s age, from ID uploads to estimates based on behavior or face scans.
Parental consent
Rules allowing minors to use a service only with a parent’s permission.
First Amendment
The constitutional protection of speech, which courts have applied to online platforms and users, including minors.

Both sides at their strongest

Each argument is written the way its best advocates would make it, followed by the strongest answer from the other side. Use them to build your case and to prepare for the other one.

Affirmative

Young teens should not have social media accounts until they’re older, just as other risky products have age limits.

  1. A1 Heavy social media use is linked to poorer mental health in teens.

    Why Early adolescence is a sensitive time for brain development and self-image. Platforms designed to maximize time and attention hit young teens especially hard.

    Evidence The 2023 Surgeon General’s advisory (double the risk of poor mental health above three hours a day); studies of social media use and depression and anxiety.

    Best answer The negative answers that most of this evidence is correlational, the average effects are small, and some teens benefit.

  2. A2 Individual families can’t solve it alone.

    Why When every classmate is on an app, one family’s rule leaves a child left out. A law changes the norm for everyone, which no family can do.

    Evidence Parent groups’ pledges to delay smartphones; surveys of parents who feel pressure to allow accounts.

    Best answer The negative replies that parental tools and community pledges can shift norms without government bans.

  3. A3 Platforms should carry responsibility.

    Why Companies have the technical ability to estimate ages. Putting the duty and the fines on platforms makes them design for it.

    Evidence Australia’s law placing fines on platforms rather than families; reports on platforms’ age-estimation tools.

    Best answer The negative argues that age checks threaten everyone’s privacy, adults included.

  4. A4 Other age limits show society accepts this kind of rule.

    Why The law sets minimum ages for driving, tobacco and alcohol because some risks are too high for children; social media can be treated the same way.

    Evidence Existing age laws; the Surgeon General’s call for stronger safety standards and age minimums.

    Best answer The negative replies that speech differs from products like tobacco; it is protected by the First Amendment.

Negative

A ban is the wrong tool: it threatens privacy and free expression, is easy to evade, and cuts off benefits.

  1. N1 Age checks threaten everyone’s privacy.

    Why To keep under-16s off, platforms must check the age of every user, which means collecting IDs or face scans from adults too and creating data that can leak.

    Evidence Cato Institute analysis of age-verification systems quoted in PBS reporting; data breach records.

    Best answer The affirmative answers that age-estimation methods can work without storing IDs, as Australia’s law encourages.

  2. N2 A ban raises serious free-speech problems.

    Why Teens have speech rights too. Blocking access to major platforms cuts them off from news, art and political discussion.

    Evidence Court rulings blocking state laws (for example, Utah’s 2023 law) after NetChoice’s challenges; First Amendment scholarship.

    Best answer The affirmative replies that the law limits accounts, not viewing public information, and that a narrowly written law can pass review.

  3. N3 Some teens depend on online communities.

    Why Isolated teens, including those with disabilities or rare interests, find support and friends online that they can’t find locally.

    Evidence The Surgeon General’s advisory noting benefits for marginalized youth; studies of online support communities.

    Best answer The affirmative argues these teens can still use messaging and other supervised spaces, and are also among those most harmed.

  4. N4 Bans are easy to get around and may push teens to riskier spaces.

    Why Teens can lie about their age or use other apps and sites with fewer protections, so a ban may move use out of sight.

    Evidence Reporting on enforcement questions about Australia’s law; history of age-limit evasion online.

    Best answer The affirmative replies that a rule doesn’t have to be perfect to work; age limits on alcohol aren’t perfect either, but they reduce use.

Strawman or steelman?

A strawman is a weak copy of the other side’s view, easy to knock down and unfair to the people who hold it. A steelman is that view at its strongest. Answer the steelman, and you’ve answered the real argument. (More on steelmanning.)

Affirmative

Strawman “They think the internet is evil and want to keep teens offline.”

Why it’s unfair Supporters target social media accounts for under-16s, not the internet as a whole.

Steelman Heavy social media use is linked to poorer teen mental health, families can’t change the norm alone, and a platform-enforced age limit makes the change for everyone.

Negative

Strawman “They don’t care about teens’ mental health; they just defend tech companies.”

Why it’s unfair Opponents raise privacy, free speech and the needs of isolated teens.

Steelman Age checks would expose everyone’s data, a ban raises free-speech problems, and it cuts isolated teens off from support while being easy to evade.

Weak arguments to avoid

Affirmative

  • “Social media is the only cause of teen depression.” Mental health has many causes; claim what the evidence supports.

Negative

  • “Teens will just get around it, so there’s no point.” Imperfect enforcement isn’t a full answer; many age laws reduce harm despite evasion.

Questions for cross-examination

Ask the Affirmative

  1. How would a platform know a user’s age without collecting IDs?
  2. What happens to a 15-year-old who relies on an online support group?
  3. Have courts upheld state laws like this?

Ask the Negative

  1. What does the Surgeon General’s advisory say about teens who use social media more than three hours a day?
  2. Can one family’s rule work when every classmate has an account?
  3. Should there be any age limit? If so, what?

Reading on both sides

Read at least one source from each side before you debate. Look up each source’s author and publisher too: who wrote it is part of the evidence.

Both sides in one place
