I used to be a Tutor for a College of Further Education, teaching Information Technology and Graphic Design, and I used to say:-
"You can try and teach them everything you know, but you can't make them learn".
Going back to your last posting from the Canadian Pigeon magazine and the article on 'Culling' - I think some of the points the author was trying to make was 'Think - Investigate - Question and don't follow Blindly, in everything'.
