In one case, (Torture to avoid the specks) the larger portion of people is better off if you pick the single person. In the other case, (Build pyramids to please Felix) the larger portion of people is worse off if you pick the single person.

Imagine that there is one tortured for 50 years and then free of any dust speck for the next 3^^^3 years.

Then we don't have "the larger portion of people" anymore. Is anything different in such a case?

Imagine that there is one tortured for 50 years and then free of any dust speck for the next 3^^^3 years.

If I understand the dilemma, in your most recent phrasing, it's this: A person who lives 3^^^3 years either:
a) has to suffer a dustspeck per year
b) has to suffer 50 years of torture at some point in that time, then I assume gets the memory of that torture deleted from his mind and his mind's state restored to what it was before the torture (so that he doesn't suffer further disutility from that memory or the broken mind-state, he only has to suffer the torture itself), He lives the remaining 3^^^3 years dustspeck-free.

If we don't know what his own preferences are, and have no way of asking him, what should we choose on his behalf?

But what does this have to do with Felix?

It is argued in the said sequence, how much better is to have 1 tortured for 50 years, than 3^^^3 people having slight discomfort.

Which preferences are in question now?

Can we have one dilemma at a time, please, Thomas? You said something about 3^^^3 years -- therefore you're not talking about the dilemma as stated in the original sequence, as that dilemma doesn't say anything about 3^^^3 years.

Which preferences are in question now?

The preferences relating to the original dilemma, are the preferences of the person who presumably prefers not to get tortured, vs the preferences of 3^^^3 people who presumably prefer not to get a dust speck in the eye.

Well, first of all, I'm assuming that you're doing that to both groupings (since otherwise I could say "Well, one has only one person and one has a massive number of people, which is a difference." but that seems like a trivial point)

So if you apply it to both, then it's just one person considering tradeoff A, (pay torture to go speck free for eons)

And another person considering tradeoff B(personally build pyramids for eons to get to live in your own collection of pyramids for some years.)

I could say that in once case the pain is relatively dense (torture, condensed to 50 years) and the pleasure is relatively sparse,(speck free, over 3^^^3 years) and that in the other case the pain relatively sparse (slave labor, spread out over a long time) and the pleasure is relatively dense (Incomprehensible pyramidgasm.).

I'm not sure if that matters or in what ways that difference matters. I'm really not up to date on how your brain handles that specifically and would probably need to look it up further.

personally build pyramids for eons to get to live in your own collection of pyramids for some years.)

No. Building pyramids as humans. And enjoying them much, much longer as they stand there, for Felix. Enjoyed by Felix.

Maybe the amount of our pleasure with Giza pyramids already exceeded the pain invested to build them. I don't know.

Can all the pains of a slave be justified by all the pleasures of the tourist, visiting the hole in the rock, he was forced carving for 50 years?

Or can a large group of sick sadists are entitled to slowly torture someone, since their pleasure sum will be greater than the pain of the unlucky one?

I don't think so.

Was it that much pain? I read in National Geographic, IIRC, that the modern archaeological conception was that the pyramids were mostly or entirely built by paid labor - Nile farmers killing time during the dry season. This may even be a good thing, depending on whether it diverted imperial tax revenue from foreign adventurism into monument/tomb-building.

I saw it, too. Had to use other example. Mayan or Aztec pyramids maybe.

Comment author: Rhwawn 06 April 2012 08:50:19PM 3 points [-]

Well, it's still a fun Fermi calculation problem, anyway.

Let's see, the Pyramids have been the targets of tourism since at least the original catalogue of wonders of the ancient world, Antipater of Sidon ~140 BC which includes "the great man-made mountains of the lofty pyramids". So that's ~2150 years of tourism (2012+140). Quickly checking, Wikipedia says 12.8 million people visited Egypt for tourism in 2008, but surely not all of them visited the pyramids? Let's halve it to 6 million.

Let's pretend Egyptian tourism followed a linear growth between 140 BC with one visitor (Antipater) and 6 million in 2012 (yes, world population & wealth has grown and so you'd expect tourism to grow a lot, but Egypt has been pretty chaotic recently), over 2150 years. We can just average that to 3 million a year, which gives us a silly total number of tourists of 2150 * 3 million or 6.45 billion visitors.

There are 138 pyramids, WP says, with the Great Pyramid estimated at 100,000 workers. Let's halve it (again with the assumptions!) at 50k workers a pyramid, 50,000 * 138 = 6.9m workers total.

This gives us the visitor:worker ratio of 6.45b:6.9m, or 21,500:23, or 934.8:1.

And of course the pyramids are still there, so whatever the real ratio, it's getting better (modulo issues of maintenance and restoration).

Maybe those pyramids in Egypt are not so bad, after all.

But with how much tourism you can justify Aztec pyramids, where people were slaughtered?

How many billion tourist should come to be worth to start with them all over again?

Comment author: Rhwawn 06 April 2012 09:19:11PM *  1 point [-]

You'd need a heck of a lot more tourism than for Egypt... although apparently there's quite a range of estimates of deaths, from less than 20,000 a year to more than 200,000 a year. Given the substantially less tourism to the Aztec pyramids (inasmuch as apparently only 2 small unimpressive Aztec pyramids survive, with all the impressive ones like Tenochtitlan destroyed), it's safe to say that the utilitarian calculus will never work out for them.

It seems to me that any historical event that was both painful to the participants, and interesting to read and learn about after the fact, creates the same dilemma that's been discussed here. Will World War Two have been a net good if 10,000 years from now trillions of people have gotten incredible enjoyment from watching movies, reading books, and playing videogames that involve WWII as a setting in some way?

The first solution to this dilemma that comes to mind is that ready substitutes exist for most of the entertainments associated with these unpleasant events. If the Aztecs had built their pyramids and then never sacrificed anyone on them it probably wouldn't hurt the modern tourist trade that much. And if WWII had never happened and thus caused the Call of Duty videogame franchise to never exist, it wouldn't have a big impact on utility because some cognates of the Doom, Unreal, and similar franchises would still exist (those franchises are based on fictional events, so no one got hurt inspiring them).

In fact, if I was to imagine an alternate human history where no war, slavery, or similar conflict had ever happened, and the inhabitants got all their enjoyment from entertainment media based on fictional conflicts, I think such a world would have a much higher net utility than our own.

Big romances have been inspired by much smaller events, it should be noted.

Let's pretend Egyptian tourism followed a linear growth

The first approximation which springs in my mind would be an exponential growth rather than a linear one.

Comment author: gwern 07 April 2012 12:11:59AM 1 point [-]

Sure - but can you offhand fit an exponential curve and calculate its summation? I'm sure it's doable with the specified endpoints and # of periods (just steal a simple interest formula), but it's more work than halving and multiplying.

Comment author: [deleted] 07 April 2012 10:41:59AM 3 points [-]

Well... integral from t0 to t1 of exp(at+b) dt = (exp(at1+b)-exp(a*t2+b))/a i.e. the difference between the endpoints times the time needed to increase by a factor of e... a 6-million-fold increase is about 22.5 doublings (knowing 2^20 = 1 million), hence about 15 factors of e (knowing that ln 2 = 0.7) i.e. about one in 150... hence the total number of tourists is about 1 billion (about six times less than Rhwawn's estimate -- my eyeballs had told me it would be about one third... close enough!)

Comment author: gwern 07 April 2012 09:14:53PM *  1 point [-]

I'm actually a little surprised that his such gross approximation puts it off by only 6x. For a Fermi estimate that's perfectly acceptable.

the pains of a slave

I've heard that the labourers who made the pyramids were actually quite well paid.

Comment author: ArisKatsaris 06 April 2012 03:14:01PM 1 point [-]

Being very very outraged isn't really an argument.

Give us your own (non-utilitarian I assume) decision theory that you consider encapsulating all that is good and moral, if you please.

If you can't, please stop being outraged as those of us who try to solve the problem, even if you feel we've taken wrong turns in the path towards the solution.

Found this by random clicking around, I expect no one's still reading this, but maybe we'll catch each other via Inbox:

How about "optimize the worst case" from in game theory? It settles both the dust speck vs. torture and the the Utility Monster Felix problems neatly.

Comment author: FeepingCreature 06 April 2012 07:15:02PM *  0 points [-]

I don't know, 3^^^3 is a pretty long time to fix brain trauma. Or are you offering complete restoration after the torture? In that case, I might just take it.

Comment author: Thomas 06 April 2012 07:39:23PM -1 points [-]

I am not offering anything at all. I strongly advice you NOT to substitute the slight discomfort over long time period with a horrible torture for a shorter period.
