Do you have any insights which you would like to share that advance the borders of rationality?

Actually, Karma is the currency of "not being a troll" on LW. Since you are most likely a troll (not very effective though, IMO. Try being more subtle next time, you're likely to get more genuine responses that way), you are bankrupt. Oops! :(

(1) We are aware. There are important reasons for keeping a moderation system anyway. Practical suggestions for rational groupthink-alleviating measures would be appreciated, although possibly not implemented. (2) Bear in mind the selection effect of who reads, votes, and replies to a thread on a given topic. Last year's survey showed more people who had decided to forgo cryonics than signed up for preservation by a factor of sixteen. (3) You are not yet a sufficiently impressive figure within this community to induce people to reconsider their judgments merely by expressing disapproval.

Er, do you have an issue with any of the arguments, rather than with Eliezer or the karma system? The only critique I can see above is the exact objection that's discussed in the "particular proof" post, and you're not presenting any argument against the analysis there.

I can't claim that the karma here is unbiased, but one pattern I can point to is that LW contrarians who engage with particular objections get upvoted more than contrarians who just reiterate conclusions. I've pointed you to a specific argument that in rationally making important d... (read more)

That's lovely and all. But how is it that my question got voted down and this nothing response got voted up?

Is it because I refer to people in cryostasis as corpse popsicles?

Well, the "nothing response" had links, and included actual facts.

As a general rule of thumb, in any online forum that uses a karma system, remarks which are polite and well written are more likely to be voted up. Remarks which are insulting or seem to be quickly typed up with little thought are more likely to be downvoted. Now, there's also a general trend that comments ... (read more)

with no large scale tests behind your claims then this is a matter of faith not science.

There is a relatively concise rebuttal of this statement in "demands for particular proof", which I quote:

"Demanding that cryonicists produce a successful revival before you'll credit the possibility of cryonics, is logically rude; specifically, it is a demand for particular proof.

A successful cryonics revival performed with modern-day technology is not a piece of evidence you could possibly expect modern cryonicists to provide, even given that the pro... (read more)

I think that the pro cryonics people in this mini-debate have failed miserably -- several people have posted "demands for particular proof" but it is not having any effect on SamAdams, who is clearly an intelligent person. I guess this just underscores the difficulty of using a rational argument to actually change someone's beliefs, unless that person is already a high-grade rationalist. I think that the nub of the problem is that SamAdams probably wants to win the debate more than he wants accurate beliefs (which is a problem that we all suffer from), because he probably doesn't have any memorable instances of motivated cognition causing him to forego reward, but he has many memorable instances of feeling a small rewarding feeling of satisfaction on winning a debate against some "nutty" belief or other. To Sam, I say, try to concretely visualize some incorrect belief that you hold hurting you long after you decided that it was a belief you wanted to hang on to. For myself, I think about times when I have convinced myself that I can hand in some important form just a few days late, or that I can jump down a high drop with a slightly injured knee and obviously I'll be OK. (the pain when my knee gave way at the bottom was horrific)

Others have already addressed this claim but I'd like to address it another way briefly. In particular, just because a specific technological goal has not yet been achieved does not mean there is no evidence for that goal. If one said in 1968 that there was no evidence that humans could go to the Moon that would be regarded as likely incorrect. Here's a brief list of technologies we don't have today. I'd be deeply surprised if you don't consider it likely that we'll have at least some of these at some point in the future: 1) practical fusion power, 2) A human mission to Mars 3) Substantial life extension 4) direct brain-computer interfaces. All of these examples fit your model of being technologies which we don't have yet. The third example, life extension seems particularly relevant. Based on your comment above I'm pretty sure you would not be willing to say "There is a total lack of evidence in support of substantial life extension of humans because its never been done and as of now nobody knows if it is even possible."

It is possible to reason about things that have never happened.

First, I don't think anyone's welcomed you to Less Wrong yet. It looks from your comments like you've been a lurker for a while?

Secondly, we do take these questions pretty seriously; it's just that we think that the best answer, based on the evidence available, is at least cautious optimism about cryonic revival (given some advances in technology well within the limits of possibility). See for instance ciphergoth's investigation of critiques for a discussion of this.

How in the world can you assign any value to that proposal? There is a total lack of evid

You have, as has been pointed out, failed to understand the purpose of my comment. You will notice I never stated anything about this paper merely some basic guidelines to follow for determining if the paper is worth the effort to read, if one doesn't have significant knowledge of the field within which the paper was written.

I apologize if my purpose was not clear, but your comment is completely irrelevant and misguided.

SamAdams-30

EDIT: This is not an evaluation of the particular paper in question merely some general evaluation guidelines which are useful.

Drop dead easy way to evaluate the paper without reading it: (Not a standard to live by but it works)

1.) look up the authors if they are professors or experts great if its a nobody or a student ignore and discard or take with a grain of salt

2.) was the paper published and where (if on arxiv BEWARE it takes really no skill to get your work posted there anyone can do it)

Criteria: If paper written by respectable authorities or ones w... (read more)

Apologies for being blunt, but your comment is nigh on useless: Andrew Gelman is a stats professor at Columbia who co-authored a book on Bayesian statistics (incidentally, he was also interviewed a while back by Eliezer on BHTV), while Cosma Shalizi is a stats professor at Carnegie Mellon who is somewhat well-known for his excellent Notebooks. I don't fault you for not having known all of this, but this information was a few Google searches away. Your advice is clearly inapplicable in this case.

Also: 3) Check for grammar, spelling, capitalization, and punctuation.

"On one hand, Eliezer writes extremely good explanations. I'm learning from his style a lot."

Yeah, but they are rather verbose he tends to use 5 words when 2 would do.

"On the other hand, many people have pointed out that he doesn't publish novel rigorous results, which kinda detracts from the aura."

If you want to be in science this is a big issue unless your trying to pull a Wolfram and we all know how that turned out.

"On the third hand, he often finds and corrects non-obvious mathematical mistakes made by other people, including m... (read more)

While awesome math ability is a great thing to have, it would only complement whatever skills Eliezer needs to succeed in his AI goals. If Eliezer finds that he lacks the math skills at a certain point to develop some new piece of mathematics, he can find a math collaborator that will be thrilled about having a novel problem to work on. I'm also not concerned about error rate. You write that the challenge is "getting the technical details right" -- this is simply not true. It's the main, big, mostly correct ideas we need to progress in science, not meticulousness. Publication is all about precision and doing it right, and it should be. But don't you feel like the science was done before the more careful rounding?
SamAdams-30

Oh I get it. I would make the same point either way especially when the idea comes from a non math person. Whenever a non math person says this kind of thing it should make anyone who has done their due diligence cringe.

If you can't do the math so for the physics if partial differential equations are beyond you then you shouldn't be talking about physics. There are many fields where knowing the "drop-dead" math is not sufficient to qualify one to talk about it.

Now I know you will all vote me down, I am rocking the boat.

1Vladimir_Nesov
Do you expect a person to end up worth off as a result of learning about some subject to less than certain level of detail? If it's better to learn a little than not at all, it's probably better to learn a few facts written in math than no facts written in math at all. It seems that you have to agree with one or the other.
SamAdams-20

Ok, I have to be honest this entire idea makes me cringe, it seems a bit to much like a cheap get out of learning the math idea. Maybe I am biased because I actually am a mathematician but these kind of ideas I think are dangerous since you take away an important bar of admission to fields like physics. If you don't understand why the math is an important bar of admission look at the google groups physics group.

To be honest I think someone would be better off spending their time learning calculus at minimum then trying to read this kind of general overview... (read more)

While I also don't see the point in the enterprise, and think many of the specific suggestions misguided, you misinterpret its intent. Read the original post for an explanation. The point isn't to learn math "in a simple form", but to explain some of the most important facts about the world with at least a bit of mathematical rigor and expressive power.

Why re-invent the wheel this has already been done if I understand correctly for example in a bit of a more specific case "Fundamental Formulas of Physics".

2Douglas_Knight
"Fundamental Formulas of Physics" is just a list of formulas without much explanation.
1Matt_Simpson
has something this general been done already? We're talking everything from physics to computer science to economics. It's the simple math of everything. If you show me, I'll believe you, but for now I remain skeptical.
