Re: On the other hand in our recent experiment nobody managed to figure out even approximate shape of their utility function

Er, that thread was pretty knackered - and I have posted about my utility function many times before - see: http://alife.co.uk/essays/nietzscheanism/

One of the distinctions that was not clear enough on that the thread, were the different types of utility functions. For example, I find it useful to talk about:

  1. the function I feel ethically obliged to maximize, a.k.a. my philosophy.

  2. the function(s) my behavior actually appears to maximize (approximately) at various levels of analysis.

  3. the function I would maximize if I was more instrumentally rational, and/or less concerned about other people's utility.

This is a very important point. I don't see how we can think sensibly about human utility without distinguishing these.

Another question that occurs to me, if (2) differs from (1) and (3), when do we call it akrasia and when do we call it self-deception?

Ben calls those "implicit" and "explicit" goals here:

Not great terminology - can we do better?

Another big one is: the goal(s) we want others to believe we have. Often "save the whales" - or some other piece of selfless signalling.

Have you donated any sperm recently?

Comment author: timtyler 12 June 2009 06:26:10AM 0 points [-]

The answer to that question is not publicly available.

However, I do have a section about sperm donation in the FAQ:
