I haven’t read the article you quote and I won’t because the conclusions you’re drawing from it are insane. Maybe the internal validity is good and if the experiment was replicated the same results would be obtained. The external validity is obviously not there. They are attempting to measure how traffic mortality from independent road crossing and they get numbers so high that it’s obvious their experiment doesn’t generalise to the question they’re actually interested in.

If we pretend that children do not cross the road until age 12 and assume 0.99 chance of surviving one crossing a day, after 100 days 63% will be dead.

Or I could just examine my own experience. My father and I both grew up within 100m of a main road with heavy traffic and we survived unscathed. The paper does not support your conclusion.

There may be a sensible conversation to be had on child supervision but my father grew up in the 50s too and it was not the hellscape you depict. If you look at deaths per 100,000 young children 5-14 they’re at worst three times current levels. By the 80s they’ve dropped to less than double current levels and people weren’t going insane wrapping their children in cotton wool and depriving them of all contact with the real world then. Deaths in childhood are so low that accidents are a minority of childhood deaths.

You’re advocating depriving children of freedom under a model of the world where childhood is so dangerous no one would survive when the trends in death rates are pretty much the same across industrialised countries while the insane helicopter parenting isn’t.
