Sounds like this could inspire a simple test as to whether someone should have access to classified information, which would also positively indicate their more mature than a twelve year old.
(Remember too that having a clearance and having access are different things. Only a rare few have unfettered access to download/print/email to/from classified systems. Lots of gamers work at/for the NSA. That doesnt mean they can all browse the f35 flight manual over lunch.)
