If the intellect and judgment of mankind ought to be cultivated, a thing
    which Protestants at least do not deny, on what can these faculties be
    more appropriately exercised by any one, than on the things which
    concern him so much that it is considered necessary for him to hold
    opinions on them?

    - John Stuart Mill, On Liberty (1859)

Perhaps the cause of this problem is refusing society the opportunity to exercise their critical thinking skills.

No matter, we can just spoonfeed everyone the received and accepted wisdom. Then there will be no need for any faculties of discernment.

    The Catholic Church has its own way of dealing with this
    embarrassing problem. It makes a broad separation between those who can
    be permitted to receive its doctrines on conviction, and those who must
    accept them on trust.
