Convince parents that teaching kids to think critically is more important than indoctrinating said child into whichever religion or political sphere the parent is already a part of. In my experience that’s a broadly impossible task. Parents want their kids to think critically only about the things the parent already rejects.
Kids that think critically are less susceptible to lazy parenting.
Nobody wants to explain to their 5yo why they can't afford a Barbie Jeep but can afford booze or going out to eat. Nobody wants a teenager that is well versed in assessing the goals and motivation of all the parties in any given situation because they'll recognize all the partial truths they get fed in an attempt to make them to take risks in a manner more like an adult. A teenager that understands statistics well would be impossible to scare into not doing "bad things". Likewise thinking critically is not a high priority thing for parents to teach.
When you're dealing with someone who can't think on the same level as you lying is just so damn easy. They are playing checkers. You are playing seven dimensional chess. Teaching kids to think critically requires a constant effort and directly negatively impacts the parents in the short term. It's like quitting smoking for 18yr, no wonder most people don't do it.
Honestly I never considered that angle, but I have to agree. I’ve always focused on grander aspects of it, but of course the small everyday lies and manipulations would be more central.
