Back in like 2001 I tried to build a psych instrument that had better than random chance of predicting whether someone would one-box or two-box in a specific, grounded and controlled Newcomb's Paradox situation - and that retained its calibration even when the the situation was modified into its probabilistic form and the actual measured calibration was honestly reported to the participants.
That sounds incredibly interesting and I'm curious what else one-boxing correlates with. By "instrument", you mean a questionnaire? What kinds of things did you try asking? Wouldn't the simplest way of doing that be to just ask "Would you one-box on Newcomb's Problem?"
I think I might end up disappointing because I have almost no actual data...
By an instrument I meant a psychological instrument, probably initially just a quiz and if that didn't work then perhaps some stroop-like measurements of millisecond delay when answering questions on a computer.
Most of my effort went into working out a strategy for iterative experimental design and brainstorming questions for the very first draft of the questionnaire. I didn't really have a good theory about what pre-existing dispositions or "mental contents" might corre...
In the future, it may be possible for you to scan your own brain and create copies of yourself. With the power of a controllable superintelligent AI, it may even be possible to create very accurate instances of your past self (and you could take action today or in the near future to make this easier by using lifelogging tools such as these glasses).
So I ask Less Wrong: how valuable do you think creating extra identical, non-interacting copies of yourself is? (each copy existing in its own computational world, which is identical to yours with no copy-copy or world-world interaction)
For example, would you endure a day's hard labor to create an extra self-copy? A month? A year? Consider the hard labor to be digging a trench with a pickaxe, with a harsh taskmaster who can punish you if you slack off.
Do you think having 10 copies of yourself made in the future is 10 times as good as having 1 copy made? Or does your utility in copies drop off sub-linearly?
Last time I spoke to Robin Hanson, he was extremely keen on having a lot of copies of himself created (though I think he was prepared for these copies to be emulant-wage-slaves).
I have created a poll for LW to air its views on this question, then in my next post I'll outline and defend my answer, and lay out some fairly striking implications that this has for existential risk mitigation.
For those on a hardcore-altruism trip, you may substitute any person or entity that you find more valuable than your own good self: would you sacrifice a day of this entity's life for an extra copy? A year? etc.
UPDATE: Wei Dai has asked this question before, in his post "The moral status of independent identical copies" - though his post focuses more on lock-step copies that are identical over time, whereas here I am interested in both lock-step identical copies and statistically identical copies (a statistically identical copy has the same probability distribution of futures as you do).
