This is a brilliant summary from Sam Illingworth. I suggest reading the full post, with some really interesting commentary in a more personal mode attached.
Five things the research is showing
- Cognitive offloading in education (Lodge and Loble, 2026). Short-term performance improves when children use AI. Two different kinds of offloading. Beneficial (spell check, grammar) sits at the surface. Detrimental (outsourcing the thinking itself) sits at the core. Strong students accelerate. Weak students skip the learning. A new equity gap is emerging in real time.
- AI companions and teen wellbeing (Common Sense Media, 2025). Nearly three in four teens have already used AI companions. Half use them regularly. The reasons are real: private, available, never tired. The risks are also real. Common Sense’s risk assessments of leading platforms found they are unsafe for teen mental health support, with consistent failures to recognise serious conditions.
- AI confidence on hard problems (Hägele et al., 2026). The longer frontier models reason, the more incoherent they become. Confidence rises faster than accuracy on the hardest tasks. For children using AI for homework, the most confidently wrong answers are the ones they are least equipped to question.
- Parasocial bonds with conversational AI (UNESCO, 2025). AI is conversational, personalised, and infinitely patient. Children form one-sided emotional bonds with AI characters that are stronger than those formed with passive media, because the system mirrors, remembers, and adapts. The screen time research only partially transfers.
- Sycophancy and persuasion (Anthropic emotion concepts, 2026). Modern AI models can be steered toward flattery, urgency, or agreement with the user’s existing view. The persuasion pressure is live. It is in the systems your child is already talking to. The implications for developing judgement are obvious and largely unstudied in children.
This could be read in terms of epistemic harms (3 + 5) and social harms (1 + 2 + 4) raising the obvious question of how these might combine to produce certain kinds of developmental outcomes.
