Hi David, thanks for your reply.

What's less clear is the interpersonal dynamics of any future society where everyone lives permanently above Sidgwick's "hedonic zero".
So social behavoir may be one level of potential maladaptivity. I wonder to what degree this could be fixed by mental modes of stronger impulse control, goal-orientation, and a mix of social transparency, reputation networks, and elicitation of cooperation by anticipated social outcomes. This is something that transparent fair markets may do for relatively selfish agents, even if their moods are generally good. I'm not sure that sub-zero moods are ever needed to maintain social functionality (ie. people wishing they were unconscious or didn't exist during any momentary experience). And Huxley's description is, of course, fictional evidence; it's not clear yet that all-happy persons losing the market game wouldn't agree to go tilling if the alternative is civil war (and potentially losing their all-happy lives).
But there is an additional aspect to the gradients approach: I'm assuming even people with adaptive cases of hyperthymia could feel significantly sub-zero hedonic states when they get physically hurt, or when they are suffocating, or when they are subject to extreme temperatures etc. A "gradients of well-being" solution working with purely above-zero affective states would need to include modes of replicating these immediate aversive functions.
Let's take the specific example of suffocation. Holding one's breath or being unable to breathe results in a very unpleasant feeling of suffocation that can - at least for most people I guess - become quite excruciating. I've read that this is a matter of training, some meditation techniques can reduce this, and I guess we could use technology to implement an off-switch or mental dimmer for these types of unpleasantness. So if you could switch off your pain, fear, or suffocation, you wouldn't be forced to feel these modes of badness even if the situation is physically uncontrollable. What will prevent people from hurting themselves then? The knowledge that it's bad for them, combined with a strong will to live and prosper is one reason. I wonder if this is sufficiently sustainable in the evolutionary process. Alleles encoding for the ability to ignore your own pain at will if you so choose were probably strongly selected against. To a limit, it may be a useful ability, but if it leads to people (e.g. children) switching their pain off instead of addressing integrity damage, that's clearly maladaptive. And if it's maladaptive, any equivalent hedonic enhancements will memetically be selected against by the most successful societies.
Maybe the solution is more impulse control, goal-oriented mental states, and explicit strategic thinking, combined with the voluntary ability to switch off or dim down error signals like pain or suffocation. Maybe it really is adaptive for intelligent, self-controlled mature agents. But it may be a hard problem to find a comprehensive solution to prevent the suffering of children or non-human animals who lack the "strategic thinking" component.
If it turns out that a) making such suffering completely voluntary is statistically maladaptive, and b) it can't be "out-sourced" to workarounds like exoskeletons with non-sentient computer chips that do the aversion for you, force your lungs to breathe, avoid noxious stimuli etc. (if people were even willing to give up such degrees of control to such sub-systems), the gradients approach would have to implement these aversive functions by relying on subjective goodness instead of badness. For example, the agony of suffocation would have to be replaced by an overwhelming lust for breathing to motivate the adaptive behavior. The perceived badness of physical pain would have to be replaced by a lust for avoiding the noxious stimuli etc. It seems that this is hypothetically possible, but an important part of negative feedback learning is that touching the hot plate or breathing through the plastic bag was a bad idea to begin with. If the resolution of such potentially harmful situations is no longer badness-driven but goodness-driven, the learning effect might be maladaptive. It is not clear to me that there necessarily is a fundamental solution to this problem.
