Earlier quoted context omitted.
I don't mean flat-out deny, There's a reason why simple social engineering works with a very high degree of success, and manipulating small children who have trust in his kidnapper (which isn't rare, since they're often family members) is even easier.
Which is why I suggested raising less gullible, passive, compliant people. Gullibility is a problem, here and elsewhere. I think raising people to be good, independent non-gullible people is a better approach than sticking trackers on them.
Young children are going to be gullible and compliant because they are young children.
That isn't something you can change until they are no longer young children. It's a question of both the teaching time required and the mental development required to learn those skills.
Similarly, some older children and adults are going to be gullible and compliant because they are mentally handicapped. Again, this isn't something you can fix by training them.
