Just put yourself in the shoe of a 6 or 8 year old.
Suddenly, you are exposed to discussions and debates on things that you know and on new stuff. You are shown how to solve interesting logical problems. And you can solve them too! Rules of new grid-based puzzles are explained and you find that you are better than your parents in solving them.
What the child has experienced is trying our new things and often finding success in them (because of the way we have designed the program). Their propensity to experiment grows multi-fold. That fear and inhibition of doing an unknown reduces, if not vanishes.
All this creates a sense of Openness in attitude that hopefully will get leveraged later in life.
