Thou Art Godshatter describes the evolutionary psychology behind the complexity of human values - how they got to be complex, and why, given that origin, there is no reason in hindsight to expect them to be simple.
But in light of Yvain's recent series of posts (i.e., if we consider our "actual" values to be the values we would endorse in reflective equilibrium, instead of our current apparent values), I don't see any particular reason, whether from evolutionary psychology or elsewhere, that they must be complex either. Most of our apparent values (which admittedly are complex) could easily be mere behavior, which we would discard after sufficient reflection.
For those who might wish to defend the complexity-of-value thesis, what reasons do you have for thinking that human value is complex? Is it from an intuition that we should translate as many of our behaviors into preferences as possible? If other people do not have a similar intuition, or perhaps even have a strong intuition that values should be simple (and therefore would be more willing to discard things that are on the fuzzy border between behaviors and values), could they think that their values are simple, without being wrong?
If someone thinks it's pretty likely that their preferences (as endorsed in reflective equilibrium) can be captured by some form of utilitarianism, then their time could easily be better spent trying to narrow down the exact form of utilitarianism (with the aim of hard-coding it) instead of trying to figure out how to specify and implement something like CEV.
Utilitarians haven't made that much progress on these issues in the last 60 years, and there are a lot of them. Do you have a further argument for why this could easily be the case?
