Here’s a hypothesis about the moral psychology involved in deciding priorities in the politics of child safety: it must create a huge sense of responsibility, mustn’t it? The kind where you’d lie awake at night, wondering whether children had been left endangered because you chose a wasteful use of resources? The kind where you’d want to consult with great care before recommending a new and untested course of action, lest it prove only a useless, intrusive distraction?

What actually happens is that policy in this area is announced by a man who doesn’t know a hash from a hashtag.
