Brainwashing Propaganda, or Morality Lesson?

[Kevin]

The human brain does not develop the physiological capacity for abstract thought until age 12, give or take a few months. It's not that they're less able, it's that they're biologically incapable of grasping the abstract at that age - period.

Generalizing about all children is a mistake as well. There are kids that can grasp the abstract younger than 12. Not everyone develops at the same rate. I stand by my statement. I've worked with young kids that get abstract sorta. Some grasp it better than others. Some don't get it at all. Your blanket statement is not a "period".
