I invoke the banner of Crockerism to communicate, and humbly beg your tolerance: I think you may be conforming the facts to the theory.
On the whole, New Agers are not people who form mistaken factual opinions about the healing powers of crystals. You are, shall I say, extropomorphizing? These people do not believe their tenets as the simplest explanation for incorrectly reported facts; they believe because Crystals are the Manifestation of the New Age of Warmth and Love and Kindness which shall Overcome the Cold Logic of Male-Dominated Science. (That this is a shockingly sexist insult to women everywhere never seems to occur to them.)

?? There are a few kinds of cognitive objects in the mind associated with "belief", including the form of the proposition itself, the qualitative degree of truth assigned to that proposition, and a few assorted emotions that affect whether we believe in something or are invoked as a consequence of believing in something - emotional commitment is an example; when we make an emotional commitment to an idea, we think it is certain, are reluctant to entertain propositions we think will contradict the idea, and believe that believing in the idea is right.

The human mind doesn't work that way. There are innate *desires*, such as emotions, which are quite distinct from the current set of *purposes*. Desires don't change, but can be easily overridden by purposes. And purposes, as mental objects, are propositions like any other proposition, that have a degree of truth like any other proposition, and can change if found to be untrue. If I have the thought "my purpose ought to be X", my purposes change as a consequence.
Purposes can rationally change whenever the justification for that purpose fails. Most people get an initial set of purposes taught like any set of facts in childhood; purposes are harder to change, because they usually teach that believing in the purpose is right, and invoke emotions like emotional commitments. But if you start shooting down other facts that were taught along with the purpose, and the purpose's surrounding memes, you can eventually move on to the justification and the purpose itself.
That's how it is for humans. I'm not saying that is how it *ought* to be, or how an AI *must* be; those are separate propositions. But as a description of the way humans operate, I think it is more accurate than either RatioBot or HappyApplet.

Do you think that these fundamental values are *true*? That they are better than certain other sets of fundamental values? That the proposition "these values are achievable and non-self-contradictory" is true?
If a Power poofed into existence and told you that all Powers had the same set of values, and that it was exactly identical to your stated set EXCEPT that "blissful" (as opposed to "happy") wasn't on the list; would you change your fundamental goals, or would you stick your fingers in your ears and hum as loud as you could because changing your beliefs would interfere with the "blissful" goal?

With seed, human, and tranhuman AIs, it will happen no matter what we do to prevent it. I don't think that our theories are yet representative of reality, only unreal abstractions from reality, just as there are no "protons", only quarks. Second only to "Do what is right", as a fundamental value, is "We don't know what the hell is going on." Any facts and any goals and any reasoning methods we program in will be WRONG and will eventually be replaced. We have to face that.
