Can training children to hold back their gut reaction change moral judgment?
Young children judged accidental harm more like adults only after a short training that told them to hold back their automatic reaction to the victim's suffering, not after training that simply told them to focus on intentions.

Priming Children's Use of Intentions in Moral Judgement with Metacognitive Training
Study at a glance
- Design
- Human experiment — Pre-test / training / post-test design: children judged cartoon protagonists in coincidence, accidental-harm and aggression scenarios, were randomly assigned to one of three short metacognitive trainings (control, mentalising, mentalising plus inhibitory alerts), then repeated the same judgments; adults did the pre-test as a developmental benchmark
- N
- N=72 · 102 children took part; 30 were excluded (one outside the age range, 29 who did not pass the training comprehension check), leaving 72 children, 24 per training group. 16 adults completed the pre-test only.
- Population
- French-speaking children aged 5 to 8 recruited at a Paris science museum, plus young adult volunteers
- Outcome
- Contrastive indexes of how much moral and social judgments distinguished protagonists by causal role (accident vs coincidence) and by intention (aggression vs accident)

What they did
Children aged 5 to 8 watched short wordless cartoons in which one character hit another on purpose, by accident, or not at all (the victim fell by coincidence), and answered questions such as who was the bad guy and who they would play with. They were then randomly given one of three brief trainings about a story in which a boy accidentally injured a friend with a ball: a control version that just mentioned two possible answers, a mentalising version stressing the boy's intentions, or a mentalising version plus executive alerts warning them not to respond automatically to the fact that someone got hurt. They then repeated the same cartoon judgments, and adults did the cartoons once for comparison.
What they found
Before training, children were sensitive to both intentions and causal role but, unlike adults, did not give intentions priority; adults weighted intentions more than causal role. Only the group whose training included inhibitory alerts changed: their intention-based distinctions increased after training (a contrast-by-time interaction with partial eta squared of 0.50), and their post-training pattern no longer differed significantly from adults. The control and mentalising-only groups did not change, and the adult-child difference persisted in those groups.
The limits
What it doesn't show
Each training group had only 24 children, and nearly a third of recruits were excluded for failing the training check (mostly in the two instruction-heavy groups), which could bias who remained. Effects were measured immediately after training on the same kind of accident scenario, so the study shows neither lasting change nor transfer to other moral situations. Some key follow-up effects were marginal, the absence of a child-adult difference after training is a null result rather than proof of equivalence, and the training may have worked by helping children sustain theory-of-mind reasoning rather than by inhibiting an emotional reaction.
Key terms
- Intent-based moral judgment
- Judging an action mainly by what the agent meant to do rather than by the harm it caused.
- Accidental harm
- Harm caused by someone with no harmful intention; the case where outcome and intention conflict most.
- Dual-process model of moral judgment
- The view that fast intuitive or emotional responses compete with slower controlled reasoning, and that inhibitory control is needed to override the intuitive response.
- Inhibitory control
- The ability to suppress a dominant or automatic response in favour of a more appropriate one.
- Metacognitive training
- Instruction that prompts people to reflect on how they are solving a problem, here including explicit warnings about a misleading intuitive response.

Which training shifted children's judgments toward intentions?
Common questions
Why do young children judge accidental harm so harshly?
According to this study, not because they cannot read intentions (they were sensitive to intentions before training) but because they struggle to override their automatic negative reaction to the harmful outcome.
Why include a mentalising-only training?
It tests whether just drawing attention to intentions is enough. It was not, which suggests the missing ingredient is inhibiting the outcome-based reaction rather than noticing intentions.
Does this mean theory of mind is irrelevant to moral development?
No. The authors argue theory of mind is necessary but not sufficient: children must understand intentions and also be able to prioritise them over the salient outcome.
