Best anthropicism contest

I arrived this morning in Prague for the 2006 Complexity conference. Soon I’ll have the photos to prove it. For now, though, I wish to blog neither about the breathtakingly beautiful city in which I find myself, nor about the meaty, succulent topic alluded to in my previous post, but instead about anthropicisms.

Inspired by Peter Woit’s almost-daily anti-anthropic broadsides, and in the spirit of my earlier Best Umeshism Contest, I hereby announce a new contest for Best Application of the Anthropic Principle. Here are a few samples to get the self-selected tautological ball rolling, not that it could do otherwise than roll:

Why do so many people seem to care about being remembered after they die? Because we only remember the ones who cared about being remembered.

Academics comprise only a tiny portion of humanity, so what are the chances of being an academic as opposed to someone else? Conditioned on asking such a question in the first place, pretty high.

Why is the moon round? Because if it were square, you wouldn’t be you — you would instead be a being extremely similar to you, except that he or she lives in a universe with a square moon.

Why am I a blogger? Because if I weren’t, you wouldn’t be reading this.

The rules are similar to the Best Umeshism Contest: up to three entries per person. Please include a name — despite the nature of the contest, “He Who Posted This” doesn’t count. Entries must be in by July 22nd. The winner (as chosen by me) gets to ask any question and have me answer it here.

    If the moon would be square, I would not write this comment on this blog about how silly the example of the square moon is.

    Anthropomorphism violates causality so it goes against physics. String theorists believe in anthropomorphism.

    Okay, I now see that what I wrote is not really an anthropicism, just a plain old contradiction. How about,

    Why do string physicists believe that the TOE is Anthropic? Because if the TOE were non-Anthropic, they would not exist.

    Let me try again with the moon for my 2nd try: ‘I learned about General Relativity and this fact allows me to calculate the size of the moon‘.

    and my 3rd entry: “Applying the principle of mediocrity I have to conclude that it is unlikely that I will win this contest.”

    “Anthropomorphism violates causality.” (rrtucci)

    Indeed this is true.

    I would add that gynomorphism violates causality even more.

    My apologies for this sexist post, but I could not resist the temptations.

    If the forces of the univeres were not fixed to produce a vast array of the most unlikely ecobalances that you could possibly imagine in your wildest dreams, then we would not be here:

    If there weren’t direct observational support for the implication of specialness, then the people on this blog might have a point:

    …we live in one universe, so we’re a sample of one. With a sample of one, you have what is called a large sample variance. And maybe this just means we’re lucky, that we just happen to live in a universe where the number’s smaller than you’d predict. But when you look at CMB map, you also see that the structure that is observed, is in fact, in a weird way, correlated with the plane of the earth around the sun. Is this Copernicus coming back to haunt us? That’s crazy. We’re looking out at the whole universe. There’s no way there should be a correlation of structure with our motion of the earth around the sun — the plane of the earth around the sun — the ecliptic. That would say we are truly the center of the universe.

    The new results are either telling us that all of science is wrong and we’re the center of the universe, or maybe the data is imply incorrect, or maybe it’s telling us there’s something weird about the microwave background results and that maybe, maybe there’s something wrong with our theories on the larger scales. And of course as a theorist I’m certainly hoping it’s the latter, because I want theory to be wrong, not right, because if it’s wrong there’s still work left for the rest of us.

    Oh thank god… anthropic dogma and a SUPER-Copernican Cosmolgical Principle will save us from having to face the AP for what it is really telling us.

    I can’t claim credit for this one, but how about: “I think therefore I am.”

    Of all the places in the huge volume of the Solar System, why do we happen to be on Earth, of all places? Because that’s one of the rare places on the Solar System where conditions support liquid water, which life takes great advantage of, so you’d expect life to evolve there. (But is that silly? Sometimes the Anthropic Principle isn’t silly, it’s just a selection effect!)

    Why did the chicken cross the road? Because humans where there to make roads.

    If it weren’t for willful ignorance, then I wouldn’t be here to laugh at them for their unscientific failure to recognize causality, even when it’s written on the wall.

    Anthropic specialness + Evolutionary Theory = A universe that leaps perpetually forward to higher orders of the same basic structure.

    OHHHH NO!! NO! NO!… can you imagine an evolutionary biologist or a creationist making that OBVIOUSLY self-evident connection?

    … much less a physicist that hates the AP because string theorists abuse it, or even a string theorist… who uses it to dodge causality.

    Science is screwed.

  17. michael vassar Says:

    I don’t imagine that I can get credit for Nick Bostrom’s items, such as the cars in the other lane really going faster, nor for the theory of evolution in one of its most general forms (we see those things that tend to persist).

    How about this?

    We don’t know get any good Bayesian evidence that MAD was a good strategy for dealing with nuclear weapons during the cold war because our observation is conditional upon its success given that its success has even a significant probability. (due to the larger populations of observers in the absence of a nuclear war). OTOH, we know that it wasn’t an impossibly bad strategy, or it would not have been used. Likewise, given the hawkish tendencies in John Kennedy’s behavior, anthropic selection may have contributed to the probability of Oswalt’s assasination attempt, causing an a-priori unlikely single gunman assasination to succeed, but anthropic selection probably didn’t contribute much because if Kennedy posed a really large existential risk and the assasination was really unlikely to succeed we would see a different history where Kennedy wasn’t elected or died in an accident or some other better assasination attempt was successful.

  18. island Says:

    Yeah, it’s more probable that Kennedy’s position was as necessary to the ecobalance at the time, as was the drastic counterbalancing measure, at its time.

    Kinda like the way that environmental awareness enables us to slow the runaway greenhouse effect, but only to the point that global warming wards off the long term runaway tendency toward glaciation that is inherent to predictions made by emprically deduced Milankovitch models.

    The anthropic balance exists between diametrically opposing runaway extreme tendencies, in all cases.

    I wouldn’t have a big butt if I didn’t sit on it and surf the net and find things like this that make me wonder why my butt’s so big.

    Because I am an anti-anthropicite, I refuse to admit that I am an anti-anthropicite.

  23. elad Says:

    Computational problems that are solvable in polynomial time are very rare, as can be seen from standard cardinality arguments. So why do we know so many polynomial-time computable problems?

    Because we tend to only pose problems such that a positive instance has a witness.

    (the missing link that would make this a true anthropicism would be that P=NP)

  24. michael vassar Says:

    As a general rule, we can safely assume that no single simple mutation will give an organism a selective advantage in its normal environment, because over evolutionary time all simple mutations will have occurred numerous times and each time a beneficial mutation occurrs it has a significant chance of becomeing fixed in the population.
    However, the anthropic principle tells us that this rule does not apply to mutations effecting human cognition. It thus suggests that human intelligence may be easier to artificially increase than that of other animals.

  25. elad Says:

    2nd try:

    Why can’t we prove circuit lower bounds?

    Because if we could, we would be able to use the proof itself to get circuit upper bounds.

  26. Scott Says:

    Elad: That’s one of my favorite insights in all of complexity theory! But I do think it strains the meaning of “anthropic” a bit. :)

    How much wood could a woodchuck chuck if a woodchuck could chuck would?

    As much wood as a woodchuck could chuck if a woodchuck could chuck would, otherwise it wouldn’t be a woodchuck.

    That said, I do think the anthropic princple is a valid idea, if a completely useless one.

    Why aren’t I going to win this contest? Because if I was able to come up with cool witticisms I wouldn’t be sitting reading blogs; I’d be out there earning cold hard cash dammit.

  29. Bram Cohen Says:

    Why have all dates thus far come before January 1. 3000? Because the universe will cease to exist on that day.

  30. Bram Cohen Says:

    Why aren’t there any immortal people? Because the immortal ones are still alive, and thus haven’t been recorded in the death records as having lived an infinite amount of time yet.

    A lot of these examples are breaking my brain. They seem more like bizarre logical non-sequiters than actual arguments. To my mind, a proper anthropic argument is one along the lines of ‘here is a model of the world which proposes several possible values, we observe that the value is x, therefore that’s the correct model variant’. Obviously such reasoning is part of the normal course of science, but if the model is too egregiously overbroad (that is, more complicated than the phenomena it’s supposed to explain) then it gets the normative term ‘anthropic’ slapped on it.

    A lot of these don’t even follow that paradigm though, they’re something incoherent which I have trouble even summarizing.

    Why is this the best anthropicism? Because if it weren’t, it would constitute self-reference and negation.

    Every Day Is an Anthropic Day

    Unmon said: “I do not ask you about other universes, but about this universe. Come, say a word about this!” Since none of the string theorists answered, he aked them: “What is the day that is not an anthropic day?”

    The Anthropic Removal Theorem

    Let:
    P = “I think.”
    Q = “I exist.”
    R = “The universe exists (in a certain configuration).”
    S = “Fill-in-the-blank exists.”
    Then:
    P => Q, by Descartes’ dictum.
    Q => R, by the anthropic principle.
    R => S, by general agreement.

    Therefore, if I stop thinking, fill-in-the-blank will cease to exist by general agreement.

    I’m trying to come up with some anthropic explanation for “The Unreasonable Effectiveness of Mathematics in the Natural Sciences”. I don’t think I have one yet, but here is my entry in its unfinished state:

    Living organisms must predict outcomes of physical processes for their survival. The prediction process must in some sense be simpler than the predicted one. (For example, it has to finish faster.) The simpler the prediction process, the higher the chance that a simple evolving organism can find it and use it to its advantage. So Universes with effective prediction processes have an advantage in harboring life. This should explain that building simple models is so successful in making predictions in our Universe.

    Why isn’t it possible for nanotechnology to create a self-replicating grey goo which reproduces until it’s consumed the entire world? Because if it were that easy to destroy the world, it would have happened billions of years ago.

    (Truth be known, the earth was destroyed by grey goo billions of years ago. We call the destroyers ‘bacteria’.)

  55. logopetria Says:

    Daniel: There’s probably a more fundamental anthropic argument along the same lines as you propose…

    Q: Why is mathematics so unreasonably effective in the natural sciences?

    A: Because if the universe weren’t regular enough to be effectively described by simple mathematical laws (at least to good approximation), it wouldn’t be regular enough for life to have developed within it.

    Sketch of a proof: What does it even mean for a universe to be so ‘irregular’ as to be undescribable (to approximation) by simple mathematical laws? It would have to be something like “No coarse-grained description of any portion of the universe is, in general, informative in giving a coarse-grained description of any other portion, nor of the same portion at another time”. This in turn would rule out the possibility of stable structures emerging (since they would stand as counter-examples to the above statement), and so no life could develop.

    Of course, as stated this doesn’t put any tight bounds on how effective mathematics would have to be, merely that it can’t be completely ineffective. Producing such a tight bound is left as an exercise for the reader!

  56. Paraphrene Says:

    String theorists are suggesting that people are objects, not that objects are people. Since people are made of the same elements that occur in nature, made by stars and other celestial bodies, then the spark of awareness might not begin or end with conception and death. It might have been around since the beginning of the universe, and it manifests itself within the individual in a limited fashion, while all awareness is distributed among natural objects which take on a certain form, like people, animals, insects, etc. Maybe these aren’t the only forms that embody awareness into a single entity.
