The science of chores
Chores aren't busywork. A growing body of peer-reviewed research links everyday household participation to how children think, solve problems, and grow up. Here's some of what scientists have actually found.
Kids who do chores show stronger working memory and self-control.
Across 207 children aged 5–13, doing self-care and family-care chores significantly predicted better working memory and inhibition — the core “executive functions” behind focus and impulse control — even after accounting for age, gender, and disability.
Tepper, Howell & Bennett (2022) · Australian Occupational Therapy Journal ↗The more they pitch in, the better they problem-solve.
In a study of 125 preschoolers, greater involvement in household chores was positively correlated with problem-solving ability — and the effect was strongest when parents guided early, then stepped back to let the child work it out.
Xia et al. (2025) · Acta Psychologica ↗Kids want to help long before they're “useful.”
A survey of more than 500 families found children start trying to help with chores as toddlers — sometimes making the job harder (“happily unhelpful”) — and that this everyday helping is tied to early prosocial development.
Hammond & Brownell (2018) · Frontiers in Psychology ↗Early chores track with how kids turn out.
A 2022 research review of longitudinal studies links early housework participation to later prosocial behaviour, academic ability, stronger peer relationships, and greater life satisfaction — and finds a parent’s own attitude toward chores is one of the biggest drivers of whether kids take part.
Lee & Tang (2022) · Int. Journal of Environmental Research and Public Health ↗Most of this research is correlational — it shows chores arelinked to these outcomes, not that chores alone cause them, and Nidori isn't a medical program. But the direction is consistent: genuinely involving kids in running the household is good for them.
Nidori's job is to make that involvement easy, age-appropriate, and something the whole family actually wants to do.
