When social psychologist Jonathan Haidt published The Anxious Generation in March 2024, his core proposal—that children should be kept off social media until at least age 16, with tech companies bearing the burden of enforcement—was treated by many as aspirational, even quixotic. The tech industry dismissed it. Libertarian critics called it paternalistic overreach. Skeptics questioned the evidence base.

That was then.

In barely two years, Haidt’s “radical” idea has become something close to a global consensus—a textbook example of what political scientists call the “Overton Window”—one that’s shifted at extraordinary speed.

The Overton Window describes the range of ideas that are considered politically acceptable at any given time, ranging from unthinkable to popular and eventually to policy. Ideas outside the window—no matter how sensible—get dismissed as too extreme, too impractical, or too politically risky to touch. But when conditions change, the window can move, sometimes gradually and sometimes with startling speed, pulling yesterday’s fringe idea into today’s mainstream. That is exactly what has happened with children and social media. Politicians everywhere are now racing to get on the right side of a window that has moved decisively.

The Floodgates Have Opened

Consider what has happened just since late 2025. Australia led the charge, enacting an outright ban on social media for children under 16 that took effect in December 2025, with monetary penalties falling squarely on the platforms—not on parents or kids. France has passed a bill banning social media for children under 15. Denmark secured cross-party support for a similar ban, expected to become law by mid-2026. Spain, Germany, Malaysia, Slovenia, Italy, and Greece are all moving in the same direction.

In the United States, where bipartisan agreement on anything feels miraculous, the Kids Off Social Media Act has attracted co-sponsors from both parties—Sen. Brian Schatz (D-HI) alongside Sen. Ted Cruz (R-TX), and Chris Murphy (D-CT) alongside Katie Britt (R-AL). Virginia enacted a law effective January 2026 limiting under-16 social media use to one hour per day unless parents opt in. Over 45 states have pending legislation.
