1. [1] Free-range vs helicopter Decision · inaction side

   Statistic

   Decades-long decline in children's independent activity is proposed as a primary cause of rising anxiety and depression among children and teens

   “"A primary cause of the rise in mental disorders is a decline over decades in opportunities for children and teens to play, roam, and engage in other activities independent of direct oversight and control by adults. Although well intended, adults' drive to guide and protect children has deprived them of the independence they need for mental health."”

   Calculation notes

   Gray, Lancy & Bjorklund (2023) review in The Journal of Pediatrics. This is an outcomes study, not a regret survey; it contextualises the inaction side by showing that reduced adult supervision is associated with better child mental health outcomes, making the inaction-side regret rate structurally lower than the action-side rate. It supports the direction of the inaction-side proxy without providing a head-count.

2. [2] Structured vs free play Decision · inaction side

   Statistic

   Decades-long decline in children's independent activity is proposed as a primary cause of rising anxiety and depression

   “"A primary cause of the rise in mental disorders is a decline over decades in opportunities for children and teens to play, roam, and engage in other activities independent of direct oversight and control by adults."”

   Calculation notes

   Gray et al. (2023) review in The Journal of Pediatrics. This paper supports the inaction side's legitimacy — free play has real mental-health value — but does not provide a regret rate. It contextualizes why some parents might regret choosing only structured activities at the expense of unstructured time.
