How to get your kids to do the right thing, convince them that it's the right thing to do. Child too young / stupid to understand moral or ethical questions? Try not to fuck them up too much while you hope they grow out of it.

That's what all these things boil down to. I get that a huge part of good parenting is not letting the, "Why don't you understand?!" frustration get to you. All this advice comes from a place of not wanting parents to beat their kids. The experts should perhaps realize that their own conescending, obviously taken too far advice only serves to make parents not trust them. Of course seeing that would require that they understand the human psychology they insist underlies their advice.
