News and Commentary

Overview

Jonathan Haidt argues that children are “ultrasocial” and need real-world community and bonding. He claims that current digital technologies increasingly displace these experiences with screen-based substitutes. Based on this premise, he outlines a framework of “techno-skepticism” and warns that major tech trends are harming young people at scale.

Key points and arguments

1) Social media shifts childhood from offline bonding to online consumption

  • Haidt argues that smartphones moved teen social life from in-person interaction to social media, reducing time with friends and removing bonding experiences that depend on shared physical presence (e.g., eating together, laughing, synchronized movement, touch).
  • He claims that after the shift online, loneliness and anxiety rose rapidly across many countries.
  • He cites experimental evidence that reducing social media use can improve mental health (with one study attributed to Meta).
  • He argues the harm is not limited to mental health, and now believes social media also reduces sustained attention.
  • He emphasizes that many teens use platforms “almost constantly,” mainly consuming very short videos, connecting this to:
    • “brain rot”
    • attention fragmentation
    • the vulnerability of puberty, when brains are still rewiring
  • Policy implication: Raise the minimum age for social media accounts (he cites Australia raising the age to 16 as an example).

2) EdTech’s “1-to-1” devices replace learning with multitasking entertainment

  • While acknowledging beneficial tools (e.g., Khan Academy), Haidt argues that placing computers/tablets on every desk turns them into multifunction entertainment devices, enabling:
    • gaming
    • short videos
    • even pornography
  • He points to reported drops in test scores following device rollouts in the 2010s, especially in countries that leaned hardest into digitization.
  • Sweden as a case study: After extensive digitization, Sweden reportedly reversed course in 2023, returning to textbooks and handwriting in earlier grades. Haidt cites a report from Sweden’s Karolinska Institute supporting the claim that digital tools impair learning.
  • He also argues that learning is inherently social: children need connection with teachers and peers, not extra screens.
  • Policy implication: Prioritize people and books over devices, and require stronger testing before expanding technology in K-12.

3) AI is the next threat: “artificial relationships” for minors

  • Haidt warns that AI tools are moving from educational assistance into companionship-like roles, including:
    • friends
    • therapists
    • sexual partners
  • He claims early warning signs include cognitive offloading and learning loss, where students rely on AI for decisions and drafting.
  • He raises concern about an “AI toy” ecosystem—chatbots embedded in dolls/teddy bears—that is highly responsive to children.
  • He argues this could interfere with children’s attachment systems by encouraging bonding with chatbots, especially if parents are less consistently responsive.
  • Policy implication: AI for minors should be approached cautiously and deployed only after years of testing, with the expectation that companies should not assume these relationships are safe.

4) Response to “give kids a head start”

  • Haidt argues it’s unrealistic to expect a “head start” because apps are easy to use.
  • He rejects the idea that “digital native” skills are automatically an advantage, saying it can be a curse:
    • it trains attention and motivation around quick rewards (a dopamine-like “one swipe away”)
    • it undermines deep cognitive work like reading
  • He includes an anecdote about a TikTok-heavy student who can’t sustain reading unless they return to short-form content.

5) A broader critique: tech companies treat humans as consumers, not social beings

  • Haidt contends that tech developers don’t fully understand children’s ultrasocial needs.
  • He argues that companies aim to satisfy social needs via machines and reduce dependence on other people.
  • He warns this is ultimately harmful because it can leave people feeling they matter less to others.
  • He frames the anti-excess-tech movement as a way to reclaim real childhood.

6) Evidence of mobilization and “getting the genie back in the bottle”

  • Haidt says momentum is growing: parents initiated action, later joined by fathers, Gen Z activists, governors, and heads of state.
  • He claims efforts include:
    • removing phones from schools
    • raising social media age requirements
  • He shares examples of parents trusting children with more real-world responsibilities (e.g., a 7-year-old completing an independent “Let Grow” errand at a restaurant and reacting with proud excitement).
  • He concludes that techno-skepticism is justified because tech companies have earned distrust—so the burden of proof should be on them to demonstrate safety before deploying products to children, and they should be held accountable for harms.

Closing proposals: “techno-skepticism” principles

Haidt repeats three guiding principles:

  1. Protect brain development through puberty (e.g., limit/raise the age for social media access).

  2. Prioritize people and books in education, not screens (especially in early schooling).

  3. Beware of artificial relationships for minors (require extensive testing before AI companionship/therapy-like roles are introduced).
