You're talking about mostly religion. Not one specific but for all of them to work they have to dumb people down, otherwise why would you follow crazy rules if you can have your faith at home without crazyness?
I believe that in a far future, as humanity gather more and more knowledge keeping religion up will be kind of hard, but until them we will have to go through the "dark ages of christianism" where our lifes will be controled by some old conservarive people. But they will die out.
