Amusingly enough, according to Wikipedia, the concept of full disclosure (http://en.wikipedia.org/wiki/Full_disclosure) originated with locksmiths in the 1800s.

And even back then, they got it right:

    > It cannot be too earnestly urged that an acquaintance 
    > with real facts will, in the end, be better for all parties.
