Utilitarianism is Useless

Utilitarianism is completely useless as a tool of public policy, Scott Alexander discovers (he doesn’t put it quite like that). In his own words: “I am forced to acknowledge that happiness research remains a very strange field whose conclusions make no sense to me and which tempt me to crazy beliefs and actions if I take them seriously.”

Why should that surprise us?

We’re all grown up (Darwinians) here. Pleasure-pain variation is an evolved behavioral guidance system. Given options, at the level of the individual organism, it prompts certain courses and dissuades from others. The equilibrium setting, corresponding to optimal functionality, has to be set close to neutral. How could a long-term ‘happiness trend’ under such (minimally realistic) conditions make any sense whatsoever?

Anything remotely like chronic happiness, which does not have to be earned, always in the short-term, by behavior selected — to some level of abstraction — across deep history for its adaptiveness, is not only useless, but positively deleterious to biologically-inherited piloting (cybernetics). Carrots-and-sticks work on an animal that is neither glutted to satiation or deranged by some extremity of ultimate agony. If it didn’t automatically re-set close to neutral, it would be dysfunctional, and natural selection would have made short work of it. (The graphs included in the SSC post make perfect sense given such assumptions.)

Pleasure is not an end, but a tool. Understood realistically, it presupposes other ends. To make it an end is to black-hole into wirehead philosophy (1, 2). It is precisely because ‘utils’ have a predetermined biological use that they are useless for the calculation of anything else.

Set serious ends, or go home. Happiness quite certainly isn’t one. (Optimize for intelligence.)

ADDED: SSC discussion threads are too huge to handle, but this comment is the first to get (close) to what I’d argue is the point. Quite probably there are others that do.
