I think a better way to put it is that it will expand the mind of people, not so much build their IQ.
On a personal level it has certainly expanded my mind to the fact that anything is possible, because there are so many things in this world that we are not exposed to. And to not just be in your own everyday world thats all about doing the same routine on a daily basis. Getting up going work, come home, and that there's nothing else possible besides that, else you cannot pay your bills.
