My language was admittedly overly dramatic, but I don’t think it make rational sense to want to change your values for the sake of just having the new value. If I wanted to value something, then by definition I would already value that thing. That said, I might not take actions based on that value if:
There was social/economic pressure not to do so
I already had the habit of acting a different way
I didn’t realize I was acting against my value
etc.
I think that actions like becoming vegan are more like overcoming the above points than fundamentally changing your values. Presumably, you already valued things like “the absence of death and suffering” before becoming vegan.
Changing opinions on topics and habits isn’t the same as changing my underlying values- reading LessWrong/EA hasn’t changed my values. I valued human life and the absence of suffering before reading EA posts, for example.
If I anticipated that reading a blogpost would change my values, I would not read it. I can’t see a difference between reading a blog post convincing me that “eating babies isn’t actually that wrong,” and being hypnotized to believe the same. Just because I am convinced of something doesn’t mean that the present version of me is smarter/more moral than the previous version.
I think the key point of the question:
1) If, for some reason, we all truly wanted to be turned into paperclips (or otherwise willingly destroy our future), would that be a bad thing? If so, why?
Is the word “bad.” I don’t think there is an inherent moral scale at the center of physics
“There is no justice in the laws of nature, no term for fairness in the equations of motion. The Universe is neither evil, nor good, it simply does not care. The stars don’t care, or the Sun, or the sky.
But they don’t have to! WE care! There IS light in the world, and it is US!”(HPMoR)
The word “bad” just corresponds to what we think is bad. And by definition of “values”, we want our values to be fulfilled. We (in the present) don’t want a world where we are all turned in to paperclips, so we (in the present) would classify a world in which everything is paperclips is “bad”- even if the future brainwashed versions of our selves disagree.
I might be misunderstanding- isn’t this what the question was? Whether we should want (/be willing to) change our values?
The problem with this is: If I change your value system in any direction, the hypnotized “you” will always believe that the intervention was positive. If I hypnotized you to believe that being carnivorous was more moral by changing your underlying value system to value animal suffering, then that version of you would view the current version of yourself as foolish and immoral.
There are essentially two different beings: carnivorous-Karl, and vegan-Karl. But only one of you can exist, since there is only one Karl-brain. If you are currently vegan-Karl, then you wish to remain vegan-Karl, since vegan-Karl’s existence means that your vegan values get to shape the world. Conversely, if you are currently carnivorous-Karl, then you wish to remain carnivorous-Karl for the same reasons.
Say I use hypnosis to change vegan-Karl into carnivorous-Karl. Then the resulting carnivorous-Karl would be happy he exists and view the previous version vegan-Karl as an immoral fool. Despite this, vegan-Karl still doesn’t want to become carnivorous-Karl- even though he knows that he would retrospectively endorse the decision if he made it!
