It's funny - I've never thought of a detective as being that aware of contingencies, but I guess they would have to be pretty good at that. I was thinking instead Machiavelli skilz, when you mentioned awareness of contingencies, but the goals would often be very different.
However when Machiavelli said "There is nothing more difficult to carry out, nor more doubtful of success, nor more dangerous to handle, than to initiate a new order of things. For the reformer has enemies in all those who profit by the older order, and only lukewarm defenders in all those who would profit by the new order, this lukewarmness arising partly from fear of their adversaries, who have the laws in their favour; and partly from the incredulity of mankind, who do not truly believe in anything new until they have had actual experience of it." M is explaining one of the very things that INFP's have the hardest time comprehending; at least to the extent that they have reached the point of living it, versus simply intellectually conceding it.
