For the parent, the teacher, the leader. The Wrong Default is about what gets installed when powerful technology arrives faster than the systems meant to govern it, and no one is actually deciding.
The argument is simple and uncomfortable: not choosing is a choice. When a tool ships with a default and no one stops to ask whether that default is right, the default becomes the decision. The book follows where those decisions land, and who absorbs the cost when the person they fall on was never really in the room.
The cost rarely lands on whoever set the default. It lands downstream, on the student, the patient, the worker, the citizen: whoever inherits a system no one chose on purpose.
The parent, the teacher, the leader. Anyone who suspects the important decisions in their life are being made by absence, and wants to take them back.
