I triggered on "work around dumb rules". Large institutions consulted by legal and behavioural experts, backed by decades of research come to the conclusion to severely restrict the effects of persuasive design on children. Taking the time to reflect on both sides of the argument without dismissing it as 'dumb rules', would be my interpretation of responsible guardianship.
As we speak, persuasive design experts, applying behavioural psychology are having wreaking measureable, wide-scale deleterious effects on our youngest generation.
Yes, I agree we should teach our children about these systems of control. At the same time, we should acknowledge that the effects are spanning wide ranges of our population, regardless of age, sex, income class and education level. Our society needs stronger controls to counter decades of psychological and sociological research, designed and funded for offensive purposes (psy-ops).
