All of Maniakes's Comments + Replies

I tried it for a few months in grad school. It works better than you'd expect, but not as well as you'd hope.

Days 2-3 were very rough, but after I acclimated, my subjective experience was similar to staying up a few hours past my normal bedtime (mild fatigue, but not unpleasant or debilitating if I was actively doing something).

Three things killed it for me:

  1. It is very difficult to maintain a social life if you need to go home and nap every 3.5 hours on a strict schedule.

  2. My class schedule was different on different days of the week, so I had to fudge my

Punster: go on a hunting trip with Mick Jagger.

Double punster: it's hunting season for Jimmy Page's former band.

Maybe he's countersignalling, deliberately offering a superficially-negative signal in order to signal that he doesn't need to send the "expected" superficially-positive signal. See this article, also by Yvain.

There are big differences between "a study" and "a good study" and "a published study" and "a study that's been independently confirmed" and "a study that's been independently confirmed a dozen times over." These differences are important; when a scientist says something, it's not the same as the Pope saying it. It's only when dozens and hundreds of scientists start saying the same thing that we should start telling people to guzzle red wine out of a fire hose.

Shouldn't that say that it is the same?

Mostly agreed. If I were to stand on a soapbox and say "light with a wavelength of 523.4371 nm is visible to the human eye", it would fall into the category of an unsubstantiated claim by a single person. But it is implied by the general knowledge that the human visual range is from roughly 400 nm to roughly 700 nm, and that has been confirmed by anyone who has looked at a spectrum with even crude wavelength calibration.

Funny, I guess, but how is it rationality related?

Here is the full article from which the quote was taken: http://www.johnlatour.com/barking_cats.htm

The preference alone is mostly harmless. When the preference is combined with the misapprehension that the preference can be fulfilled, it may harm the person asserting the preference if it leads them to make a bad choice between a meowing cat, a barking dog, or delaying the purchase of a pet.

If the preference order were (1. Barking Cat, 2. Barking Dog, 3. Meowing Cat, 4. No Pet), then the belief that a cat could be taught to bark could lead to the purchase/adoption of a meowing cat instead of the (preferred) barking dog.

Likewise, in the above preference o... (read more)

"I would like to have a cat, provided it barked" states that U(barking cat) > U(no cat) > U(nonbarking* cat). Preferring a meowing cat to no cat is a contradiction of what was stated. The issue you raise can still be seen with U(barking cat) > U(barking dog) > U(no pet) > U(nonbarking cat), however - a belief in the attainability of the barking cat may cause someone to delay the purchase of a barking dog that would make them happier. *In common usage, I expect that we should restrict it from "any nonbarking cat" to "ordinary cat", based on totally subjective intuitions. I would not be surprised by someone who said "I would like an X, provided it Y" for a seemingly unattainable Y, and would not have considered whether they would want an X that Z for some other seemingly unattainable Z. I think they just would have compared the unusual specimen to the typical specimen and concluded they want the former and don't want the latter. This is mostly immaterial here, I think.

That's strictly ruled out by the wording in the quote. While people often miscommunicate their preferences, I don't see particular evidence of it there, or even that the hypothetical person is under a misapprehension. To take it back to metaphor: the flip side of wishful thinking is the sour grapes fallacy, and while the quote doesn't explicitly commit it, without context it's close enough to put me moderately on guard.

There are valid quibbles and exceptions on both counts. Some breeds of cats make vocalizations that can reasonably be described as "barking", and water will burn if there are sufficient concentrations of either an oxidizer much stronger than oxygen (such as chlorine triflouride) or a reducing agent much stronger than hydrogen (such as elemental sodium).

In the general case, though, water will not burn under normal circumstances, and most cats are physiologically incapable of barking.

The point of the quote is that objects and systems do have innate... (read more)

I replied as follows: "What would you think of someone who said, "I would like to have a cat, provided it barked"? [...] As a natural scientist, you recognize that you cannot assign characteristics at will to chemical and biological entities, cannot demand that cats bark or water burn. Why do you suppose that the situation is different in the "social sciences?"

That since their preference harms nobody (apart from unadopted cats) and the utility function is not up for grabs, I have no grounds to criticize them?

I'm assuming that most everyday purchases are frequently repeated (e.g. you buy milk and eggs every week), so the cognitive costs of figuring out the best place to buy milk and eggs can be amortized out over many transactions.

There's another good reason why savings in terms of percentages are reasonable to consider, beyond just absolute savings. You can travel fifteen minutes to the store where a shirt costs $20, and buy two of them. This makes it a much more complicated decision than saving $20 on a television. Televisions are something that most people don't need a lot of. Even if there was a half-price sale on televisions, you probably still wouldn't be tempted to buy two of them (unless you're really into giving televisions as gifts or you think you can turn a profit on e-bay). So with a half-price sale you'd probably just by one TV and smile as you save $1,010 off the sticker price. So for just $20 off of a $2,000 television, I really wouldn't expect anyone to be tempted into buying two sets. It's a very simple tradeoff, then: Would you prefer $20, or 15 minutes? (It's still probably worth travelling, unless you make more than $80 per hour...) Shirts, though, are the kind of thing you'd possibly buy twice as many of if the price were halved. Looking ahead to when the first shirt gets worn out, you'll have to replace it. This could cost you another $40, plus the duration of a second shopping trip, which is probably longer than 15 minutes in total. Meanwhile, if you spend fifteen minutes now and buy two shirts, the fifteen minute travel time will pay itself back in the long run and you'll save the $40 that the second shirt would have cost you. This logic can be extended: If you are looking ahead that far, and have enough disposable income to spend $80 on shirts, you can avoid the second shopping trip by buying two shirts at the closer, more expensive store. But now your 15 minutes are worth $40, not $20. And for that price you could buy four shirts at the cheaper store... Ultimately your decision to travel 15 minutes might come down to how much closet space you have for extra shirts, how much of a hurry you're in right now, and how much money you have access to. Basically, there a

The society which scorns excellence in plumbing as a humble activity and tolerates shoddiness in philosophy because it is an exalted activity will have neither good plumbing nor good philosophy: neither its pipes nor its theories will hold water.

John W. Gardner

6Emile
I agree with the general thrust, but ... even though modern western society does scorn plumbers (compared to philosophers), our pipes do hold water, and I don't have any complaints about the overall quality of plumbing. Our society may not have much high words of praise for excellence in plumbing (you're more likely to talk about your hobby as a wildlife photographer than your job fixing toilets on your OK Cupid profile, even if you're average at the first and excellent at the second), but good plumbers get more money than bad plumbers, which is enough to get quality plumbing. By contrast, good philosophers get more praise from their peers than bad philosophers do, which is both harder to evaluate and less motivating. So I don't think it's a matter of humble activity / exalted activity; designing bridges and transplanting hearts are exalted activities too, and we don't tolerate much shoddiness there.

In both cases, the tradeoff is the same - drive fifteen minutes to save twenty bucks - but people were much more willing to do it for the cheap item, because $20 was a higher percentage of its total cost. With the $2000 TV, the $20 vanishes into the total cost like a drop in the ocean and seems insignificant.

Evaluating cost savings as a percentage actually makes a certain amount of sense when evaluating policies rather than acts. Cheaper purchases tend to be much more frequent: you probably buy many more shirts than you do big-screen TVs, so expending t... (read more)

Or maybe it's just outrageous to ask for $40 when it's clearly possible to sell it for $20. So you kind of punish the shop that asks for $40 because you see them as dishonest and morally repulsive. Sometimes you also have to pay attention to what behavior you encourage with your actions. Not only the immediate dollar value. Why don't Christmas tree sellers sell the last, leftover Christmas trees for much cheaper, right before Christmas? Because then lots of people would just wait until that time and then buy it cheap. If buyers know that the seller will rather throw out the goods to the thrash rather than sell them cheaper then they will just casually buy the tree knowing that the price is stable and it's all fair. Short-sighted optimization would tell the seller to just sell the leftovers cheaper rather than throw them away. Similarly, you may want to "send a message" to the $40 shop that you will rather drive a lot than participate in such an outrageous deal.

"...frequent purchases can have a substantial effect on your overall financial situation, but indulging in overpayment for convenience on the odd big one-time purchase is an affordable luxury." I'm not really sure if that explains the behavior as one could also argument that the "cognitive burden" of extra effort for everyday purchases is greater than putting it into those big one-timers.

I answered yes to your hypothetical, but I am not currently signed up for cryonics and have no short- or medium-term plans to do so.

My reasons for the difference:

  1. In your hypothetical, I've received a divine revelation that there's no afterlife, and that reincarnation would be successful. In real life, I have a low estimate of the likelihood of cryonics leading to a successful revival and a low-but-nonzero estimate of the likelihood of an afterlife.

  2. In your hypothetical, there's no advance cost for the reincarnation option. For cryonics, the advance cost

For particularly important decisions, consider contemplating them at different times, if you can. Think about one thing Monday morning, then Wednesday afternoon, then Saturday evening, going only to the point of getting an overall feel for an answer, and not to the point of really making a solid conclusion.

This seems congruent with the folk idea of "sleeping on" difficult or particularly important decisions rather than coming to a decision on the spot, and with the legal practice of having "cooling off periods" after a purchase is made or a contract is signed, during which one party can void the agreement.

1Logos01
Very often, however, the immediate judgment is the most representative of the individual's honest opinion on any given topic. "Sleeping on" things is only useful when there is additional data to be reviewed before making said decision. Once you've already got all your givens, there's nowhere to go but to their conclusion.
