As a health educator, I work very hard to explain hopelessly complex issues (such as how our brain works) to kids. The model I use is based on the Triune Brain perspective by Paul MacLean at his NIH lab forty or more years ago. I'm currently using the same model to teach "Senior Brain" classes to those 65 years and older. Obviously, human fallibility and gullibility stems from having three competing brain functions (rational, emotional and survival). Though we can "understand" why human reason doesn't stand a chance against instinctive brain functions, the vanity of Homo Sapiens prevents us learning how to consciously regulate primal brain impulses. For more on this challenging topic, see the website www.copingskills4kids.net, a world-wide effort to help develop greater awareness of these competing neurological elements.
