This is a thought that occured to me on my way to classes today; sharing it for feedback.
Omega appears before you, and after presenting an arbitrary proof that it is, in fact, a completely trustworthy superintelligence of the caliber needed to play these kinds of games, presents you with a choice between two boxes. These boxes do not contain money, they contain information. One box is white and contains a true fact that you do not currently know; the other is black and contains false information that you do not currently believe. Omega advises you that the the true fact is not misleading in any way (ie: not a fact that will cause you to make incorrect assumptions and lower the accuracy of your probability estimates), and is fully supported with enough evidence to both prove to you that it is true, and enable you to independently verify its truth for yourself within a month. The false information is demonstrably false, and is something that you would disbelieve if presented outright, but if you open the box to discover it, a machine inside the box will reprogram your mind such that you will believe it completely, thus leading you to believe other related falsehoods, as you rationalize away discrepancies.
Omega further advises that, within those constraints, the true fact is one that has been optimized to inflict upon you the maximum amount of long-term disutility for a fact in its class, should you now become aware of it, and the false information has been optimized to provide you with the maximum amount of long-term utility for a belief in its class, should you now begin to believe it over the truth. You are required to choose one of the boxes; if you refuse to do so, Omega will kill you outright and try again on another Everett branch. Which box do you choose, and why?
(This example is obviously hypothetical, but for a simple and practical case, consider the use of amnesia-inducing drugs to selectively eliminate traumatic memories; it would be more accurate to still have those memories, taking the time and effort to come to terms with the trauma... but present much greater utility to be without them, and thus without the trauma altogether. Obviously related to the valley of bad rationality, but since there clearly exist most optimal lies and least optimal truths, it'd be useful to know which categories of facts are generally hazardous, and whether or not there are categories of lies which are generally helpful.)
As stated, the only trap the white box contains is information... which is quite enough, really. A prediction can be considered a true statement if it is a self-fulfilling prophecy, after all. More seriously, if such a thing as a basilisk is possible, the white box will contain a basilisk. Accordingly, it's feasible that the fact could be something like "Shortly after you finish reading this, you will drop into an irreversible, excruciatingly painful, minimally aware coma, where by all outward appearances you look fine, yet you find out the world goes downhill while you get made to live forever", and there's some kind of sneaky pattern encoded in the pattern of the text and the border of the page or whatever that causes your brain to lock up and start firing pain receptors, such that the pattern is self-sustaining. Everything else about the world and living forever and such would have to have been something that would have happened anyway, lacking your action to prevent it, but if Omega knows UFAI will happen near enough in the future, and knows that such a UFAI would catch you in your coma and stick you with immortality nanites without caring about your torture-coma state... then yeah, just such a statement is entirely possible.
But the information in either box is clearly an influence on the universe - you can't just create information. I'm operating under the assumption that Omega's boxes don't violate the entropy principles here, and it just seems virtually impossible to construct a mind such that Omega could not possibly, with sufficient data on the universe, construct a truth and a falsehood for which when learned by you would arrive at causal disruption of the world in the worst-possible-by-your-utility-function and best-possible-by-your-utility-function manners respectively...
