The effective altruism movement and the 80000 hours project in particular seem to be stellar implementations of this line of thinking.
Also seconding the doubts about the refrain from saving puppies - at the very least, extending compassion to other clusters in mindspace not too far from our own seems necessary from a consistent standpoint. It may not be the -most- cost-effective, but no reason to just call it a personal interest.
Really liked this one. One thing that bugs me is the recurring theme of "you can't do anything short of the unreasonably high standard of Nature". This goes against the post of "where recursive reasoning hits bottom" and against how most of good science and practically all of good engineering actually gets done. I trust that later posts talk about this in some way, and the point I touch on is somewhat covered in the rest of the collections, but it can stand to be pointed out more clearly here.
It's true that Nature doesn't care about your excuses. No matter...
I know I'm way behind for this comment, but still: this point of view makes sense on a level, that saving additional people is always(?) virtuous and you don't hit a ceiling of utility. But, and this is a big one, this is mostly a very simplistic model of virtue calculous, and the things it neglected turn out to have a huge and dangerous impact.
Whoever knowingly chooses to save one life, when they could have saved two - to say nothing of a thousand lives, or a world - they have damned themselves as thoroughly as any murderer.
First case in point: can a ...
Actually Brennan's idea is common knowledge in physics - energy is derived as the generator of time translation, both in GR and in QFT, so there is nothing new here.
Great observation. One inaccuracy is that velocity in special relativity isn't quite the same as acceleration in GR - since we can actually locally measure acceleration, and therefore know if we're accelerating or the rest of the universe is. This is unless you also count spacetime itself in the rest of the universe, in which case it's best to specify it or avoid the issue more decisively. The actual equivalence is accelerating vs. staying in constant velocity/still in a gravitational field.
Another interesting point is that this chain of "character of law"...
Cool story, great insights, but I gotta say, huge planning fallacy on Jeffreyssai's part. Giving rigid deadlines on breakthroughs without actual experience with them or careful consideration of their internal mechanisms, and when the past examples are few and very diverse.
I do agree that speed is important, but maybe let's show some humility about things that humans are apparently hard-wired to be bad at.
If there were something else there instead of quantum mechanics, then the world would look strange and unusual.
If there were something else instead of quantum mechanics, it would still be what there is and would still add up to normality.
About a few of the violations of the collapse postulate: this wouldn't be the only phenomenon with a preferred reference frame of simultaneity - the CMB also has that. Maybe a little less fundamental, but nonetheless a seemingly general property of our universe. This next part I'm less sure about, but locality implies that Nature also has a preferred basis for wavefunctions, i.e. the position basis (as opposed to, say, momentum). Acausal - since nothing here states that the future affects the past, I assume it's a rehash of the special relativity violation...
Just one quick note: this formulation of Bayes' theorem implicitly assumes that the A_j are not only mutually exclusive, but cover the entire theory space we consider - their joint probability is assigned a value of 1.
I know I'm really late with this, but what do you consider as "studying science"? Making a career of it? Does being an engineer count (I guess it does)? Or is getting (an amount of knowledge equivalent to) a B.Sc. enough too? Maybe even less than that, learning cool nuggets of science as a hobby? I think this should be better defined. If it's just a career that counts, I'm afraid that the main inhibitor is not interest, but fear for career prospects. Most often when I head people's reasons not to pursue a career in science, it's because they don't think t...
Then "Gomboc righting itself when on a flat surface" will have an inherent 100% probability. This doesn't refute the example.
Three things bother me here, and they're all about which questions are being asked.
The "tree falling in a forest" questions isn't, as far as I've encountered it outside of this blog, about the definition of sound. Rather, it's about whether or not reality behaves the same when you do not observe it, an issue that you casually dismissed, without any proof, evidence, or even argument. There are ways to settle this dispute partially, though they are not entirely empirical due to the nature of the conundrum.
Ignoring the question of free will, ill defined
There's a clarification to be made here, in the bottom line - you were right to say that you shouldn't be expected to believe that the big, elaborate argument violates known laws of physics if no specific step had been shown to do it, but this doesn't mean that no such step exists. It may be that the arguer (and anyone else, for that matter) doesn't understand a subtlety that allows the mechanism to coexist with the laws of Nature. This has happened with the proposition of the ERP experiment, when it was initially thought to violate causality, but it was l...
No. 6 - I go again to logic and formal math, where you can never define any term by extensions because sensory perceptions aren't reliable enough to give the needed certainty of Truths. Then you will have to start from some undefined elementary terms and work up from there. Other than this, though, this rule of thumb seems quite trustworthy.
No. 29 - that's just inaccurate. As you said, there are more and less typical examples of a cluster. Hinduism is a typical example, so we stop there. But if a case is a borderline member of a cluster, you will need to r...
I feel the need to address the python vs. modern art thing too - if you just compare the extensional list of art against the intensional definition, you'll see that modern arts pass as arts (at least sometimes) while python definitely doesn't. Modern arts involve some work, are intended to inspire aesthetic emotions, and often do in some people experiencing them. Python, while being an elegant tool, was not (probably) designed with the primary intention of producing emotions, but rather with the intention of being a convenient tool to code.
Also, there is a...
Well, I think that if you are to be true to the message here, you should go even if the students and professors themselves are not above the norm, since the culture of addressing the original purpose directly would have merit in its own right. Unless you believe this expenditure of time isn't worth the while without the bundled social benefits of having a degree.
As for the PhD level, I think that after that the teaching part is nearly gone, and the service the institution can provide is mostly providing a productive environment and tools to conduct research.
On a different note, calling a ball a spheroid isn't really tabooing it, it's just a synonym.
While the general argument is valid, I'm not sure how these accusations of socially-derived rules making up traditional rationality. There were many mathematicians and scientists before Bayes was born, and they derived their beliefs from logic and evidence, not social norms. Take Galileo as an extreme and famous example. Is there any evidence behind these unflattering descriptions of traditional rationalists?
This "if" embodies the decrease of risk from being part of a crowd. In a protest of 5000, 20 may be pulled in, but the leader is much more likely to be one of them than any one person in the crowd.
I agree with the benefits of narrowness, but let's not forget there is a (big) drawback here: science and math are, in their core, built around generalizations. If you only ever study the single apple, or any number of apples individually, and not take the step of generalizing to all apples, or maybe all apples in a given farm, at least, you have zero predictive power. The same goes for Rationality, by the way. What good is talking about biases and Bayesianism, If I can only apply it to Frank from down the street?
I'm arrogantly confident you agree with me ...
>A refused claim is (legally) an event that was never covered by the insurance, and is therefore irrelevant if the question is "take policy A or not at all".
This implicitly assumes all legal cases are clear-cut and independent of perspective or legally-related capabilities; and also perfect knowledge of the fine print (which is desirable but not always realistic).
Usually the insurance company has more relevant experience, better specialized lawyers and generally more resources to spend fighting claims than the consumer. So they can often successfully claim that your particular circumstances are not covered after the fact, even when you believe they were.
