I think this is a common fallacy. My 1N opening bid does not show a 14 count with a 6 card minor. If you would truly like the entire list of hands that I would open 1N with, in roughly decreasing order of probability, it is:
-Any "balanced hand" with no singletons or two doubletons and 15 to a non-amazing 17 points, including a 5 card major
-Often, a good hand with 14 points and lots of intermediates and a 5 card suit
-Often, a hand with 22(54) shape and 14-16 points, depending on my hand
-Often, a hand with a 6 card minor and 322 in the other suits, 14-16 points, depending on my hand
-Occasionally, a hand with a stiff Q or K, a 5 card minor, and 4-3 in the other two suits (edit, thanks Phil)
-Occasionally, a very bad hand with 18 points
-Occasionally, a remarkable hand with a 6 card minor and 322 in the other suits, 13 points
-A tactical bid/psyche
Notice that the kinds of hands you are talking about only make up a small percentage of the time I would open 1NT. If you want to completely change your style to cater to the less than 5% chance I may be "goofing around", that is okay, but I doubt you will find it is very effective. My point is that even if whenever I opened 1NT, my partner listed this entire set of possibilities, I would be very surprised if any of my opponents would think it necessary to bid in a completely different way.

As to the first part of your sentence, since I would accept a NT invite with Qx Txx AKQJxx Qx, I do not see why I cannot possibly think Jx Txx AKQJxx Qx is "worth" a good 14 points. I suppose if you forced me to assign a number to it, I would say "about 14", but part of bridge is bidding tactically, and I do not see why we should not apply that element to opening bids.
Is opening 1S with KQJxx ATxx xxx x a "psyche" to you also in first seat, playing a standard 2/1 style? I would always open this hand, not because I consider it worth 12 points, but because I think it is tactically sound and that I will do better in the long run to open this kind of hand. If you do not object to the second example, I do not think you should object to the first.
