Ok, this is the point where I decide to be mildly obnoxious and use Sam's work as an indication that humans have many more cognitive biases and fallacies than even people at LW realize. In particular, the above post displays a large amount of artificial classification in trying to claim that specific scale issues somehow become differences in kind. This seems very similar to (for example) creationists who claim to accept microevolution but not macroevolution. Moreover, the presence of these problems does not leave in some cases even after prolonged exposure to careful rational and critical thinking.

The fourth point does a good example of this:

Cryonics has many single-points of failure and many unresolved questions: A couple examples: a.) Is there anything fundamental about death the precludes the possibility of restoring life? b.) Is it possible to maintain self/person-hood by simply maintaing physical state integrity? c.) Is the general concept of organ preservation able to be scaled to entire bodies or is there a limit to what can be restarted? d.) Is a living organism required to overcome the effects of the cryopreservation? etc.

To be sure, there are other problems here as well (such as the heavy overlap between a,b and c and the fact that a seems to take "death" as a potentially ontological fundamental phenomenon), but the issue I want to focus on is c, "is the general concept of organ preservation able to be scaled to entire bodies or is there a limit to what can be restarted?" This is an assertion that while any single part of a system can be restarted, somehow it takes a much higher burden of evidence to assert that the entire system can be restarted. This seems similar to the micro/macro fallacy but I'm not sure what precisely the fallacy is. I'd almost be tempted to coin a new one, something like "failure to reduce."

I have to wonder if this sort of thing is an indication that LW is not substantially succeeding in improving rationality. Sam's first comment on LW was about a year ago, and his posting quality has either remained the same or declined during that time (although to be fair it is difficult to distinguish between rationality and civility issues in his case.) Now, it seems based on comments Sam has made that it is probable that he hasn't read the sequences. Sam's emphasis on wanting to only read "authorities" may play a role but that may be simply a specific defense in this case against reading posts which challenge his worldview (the strongest evidence for this case is that people have summarized the demand for particular proof argument and he's still ignoring or misinterpreting it) . Is Sam a representative sample? If there are a substantial number of people here who have gone through and interacted with the community and yet have not improved their rationality, does that suggest we have a problem that requires a change in tactics?

Sam certainly isn't the only example of this sort of problem, and even the general community here sometimes demonstrates strong biases that impact their evaluation of claims(I've noticed this most strongly where evaluations of historical claims are concerned). So, are we succeeding? Should the presence of people like Sam mean we should be concerned that we are not?

I am going to break my own rule and respond to plonked thing.

It says: "To be sure, there are other problems here as well (such as the heavy overlap between a,b and c and the fact that a seems to take "death" as a potentially ontological fundamental phenomenon), but the issue I want to focus on is c, "is the general concept of organ preservation able to be scaled to entire bodies or is there a limit to what can be restarted?" This is an assertion that while any single part of a system can be restarted, somehow it takes a much higher burden of evidence to assert that the entire system can be restarted."

Not even close, missed by a mile, I am merely point out that these issues are by no means a resolved. If you think they are then you are blithely unaware of current science.

"This seems similar to the micro/macro fallacy but I'm not sure what precisely the fallacy is. I'd almost be tempted to coin a new one, something like "failure to reduce.""

Wrong again as per-usual, you mindless chat bot, I made no logical error since I never asserted anything I merely pointed out a set of open questions which still have yet to be resolved. Your blind faith that the answer is one way and not the other is a reflection of your own arrogance and humiliating ignorance, not of any logical failings on my part.

As for coining a term here's one: HumanusIgnoramius - a human devoid of real knowledge while having no clinically diagnosed mental shortcomings/deficiencies.

"Sam's emphasis on wanting to only read "authorities" may play a role but that may be simply a specific defense in this case against reading posts which challenge his worldview (the strongest evidence for this case is that people have summarized the demand for particular proof argument and he's still ignoring or misinterpreting it) "

1.) Where does Eliezer work? Has he worked any where else of note? 1.A) Singularity Institute as to the other part not that I am aware. If he had worked at a real research lab like Intel or something I think his inflated ego would dictate he tell us all that he poured coffee in the lab for the real scientists.

2.) Is his place of employment significant? 2.A) No (by that I mean small influence, small budget, small accomplishments)

3.) Has Eliezer published? 3.A) Yes in Springer

4.) Was it a technical paper? 4.A) No

5.) Is the journal respectable? 5.A) Sure but it is also well within reach of your average college student to publish there.

6.) Has he published anything else? 6.A) Yes, a single chapter in a book

7.) Is this significant? 7.A) Not so much because it is really not that far out of the ordinary

8.) Does Eliezer have any advanced degrees? 8.A) No

9.) Are Eliezer's claims of authority based on real scholarship? 9.A) Based on above answers no since two non-technical works hardly count as sufficient scholarship. (Plus I watched the youtube video about his mind and he said his IQ is 138 or something like that. He didn't even say what test; my guess is Cattell meaning his IQ is closer to 119. For some one who speaks so arrogantly thats a little low and a little devoid of achievement to make up the difference.)

10.) If Eliezer is not a personal acquaintance of mine, and all the people who quote him are mindless chat bots, and a gaggle of eager young minds hoping to be molded by the first thing that comes down the pike. Is he a source that I will trust and bother to read for more then the amusement of mocking it? 10.A) No, no way, absolutely not, never, negative ain't gonna happen, not a chance lance, not in a million years, over my dead body, over my rotting corpse etc.

I hope I have put this issue to bed. Gosh I have no life here I am throwing more pearls before swine.

I do however have a confession to make: I have since I started reading this "blog" dearly wanted to ridicule the majority of the people here. What I realized though is that it would all sound the same since you all are really deserving of the same ridicule.

(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.

Karma Encourages Group Think:

LW Karma system allows people to vote up or vote posts down based on good or usless reasons. Without it you cannot make high-level posts or vote idiotic comments or posts down.

Essentially Karma is the currency of popularity of LW. This being said I would wager that this encourages a group think attitude; because people have a strong motivation to get karma and not such a strong incentive to think for themselves and to question the group.

I would also posit that this kind of system causes a stagnation in ideas and thinking within the group. This is evident on LW with how many posts just seem to rehash old news.

Pearls before swine.

Sam,

The nanotech required is so far outside of current science that trying to predict what it can do is a hard problem at best

I wanted to pick on this in particular, because you seem to be saying "there's no overwhelming evidence either way, so I can believe whatever I want". But really, advanced molecular nanotechnology does have evidence in favor of its eventual achievement:

For example, progress in self-assembly with DNA nanotechnology (http://www.physorg.com/news9322.html), primitive nanomachines that locomote (http://www.nature.com/nnano/journal/v2/n2/abs/nnano.2006.210.html), etc. These are small steps that we are seeing today, yes.

You can't claim to be doing good-quality futurism if you don't assign some probability to current trends continuing, and it is especially bad to say "you can't prove that X will happen, therefore I'm allowed to believe that it definitely won't happen".

Rather, you should assign a probability to the events in question occurring.

Which means that there is a probability of cryonics working, and most people say it's around 10%.

"You can't claim to be doing good-quality futurism if you don't assign some probability to current trends continuing, and it is especially bad to say "you can't prove that X will happen, therefore I'm allowed to believe that it definitely won't happen"."

I don't claim to be doing futurism at all I think the idea is a crock. Its an excuse for no scientists to pretend to participate in science.

Looking at what may happen has its uses but getting your knickers in a bunch about it is just stupid.

Now I am board of this conversation so: *plonk

It seems to me that "emergence" has a useful meaning once we recognize the Mind Projection Fallacy:

We say that a system X has emergent behavior if we have heuristics for both a low-level description and a high-level description, but we don't know how to connect one to the other. (Like "confusing", it exists in the map but not the territory.)

This matches the usage: the ideal gas laws aren't "emergent" since we know how to derive them (at a physics level of rigor) from lower-level models; however, intelligence is still "emergent" for us since we're too dumb to find the lower-level patterns in the brain which give rise to patterns like thoughts and awareness, which we have high-level heuristics for.

Thoughts? (If someone's said this before, I apologize for not remembering it.)

"We say that a system X has emergent behavior if we have heuristics for both a low-level description and a high-level description, but we don't know how to connect one to the other. (Like "confusing", it exists in the map but not the territory.)"

This says absolutely nothing and brings no new insights to the table; I would think you should delete it from you comment. This is a well understood fact and needs no restating, unless, as I suspect the general level of scientific ability is as low as I would imagine it is. This is a transhumanist blog after all and you guys do have a reputation to uphold (I know you guys think this is rationalist community but your views on such things are so warped as to render your efforts nearly fruitless in the area of rationalism).

"intelligence is still "emergent" for us since we're too dumb to find the lower-level patterns in the brain which give rise to patterns like thoughts and awareness, which we have high-level heuristics for."

Or maybe intelligence is an extremely complex phenomena and the knowledge and the technology required to completely understand it has yet to come about.

I think this recurrent idea of how humans are so dumb therefore we need AI is a sort of copout. Basically you're saying I am way to lazy to do the hard science so I will hope that AI will solve it. What makes it even more of a copout is that you personally are probably not even involved in the creation of AI.

A bit of an aside:

I would like to point out some interesting parallels between transhumanist singularity its (not wanting to leave out those I have *plonked) and peoples and Christians (everyone draw back in horror).

Christians believe in salvation through Jesus - you guys believe AI, cryonics and technology will save you.

Christians believe in an all powerful God - you hope to create an all powerful AI the ideal god that does what you want and allows you to be as immoral as you like.

Christians believe in the afterlife and resurrection after death - you guys think that cryonics and computers are your tickets to resurrection and immortality.

I could keep going but I think my point is clear the parallels are to obvious to deny. Hence forth we shall term your beliefs Christianity v2.0.

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 suggest that the 'pro cryonics people' have cause to object to your presumption. You have defined their success and failure in terms of their ability to make SamAdams concede a point. Why on earth would people want to accept either that challenge or that judgement?

I haven't taken a pro-cryonics stance in this mini-debate but I suspect you refer to me too, given that I brought up "demands for particular proof". For my part convincing SamAdams to preserve himself with cryonics is exactly the opposite of what I desire. I want him to go away. Not go and preserve himself so we're stuck with him forever.

Comment author: SamAdams 09 July 2010 06:35:39AM -8 points [-]

I could say the same about you and your blather. Your arrogance and ignorance offend me.

Not to mention the great glee I shall experience when your attempts at rationality are shown to be the farce that we all know them to be. I assign no value to your judgement and you assign no value to mine (big deal).

If you have some actual argument to make great if its just more flaccid cheerleading then please allow me the honor.

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)

Comment author: SamAdams 09 July 2010 06:24:14AM 0 points [-]

I am going to try to put this in a way that you guys will understand.

My opinion of cryonics is based on these facts: 1.) Cyropreservation as it stands has only managed to preserve tissue with a high degree of fidelity. 2.) The only instance of revival is taking a preserved organ and defrosting it and inserting into a living organism. (This is much simpler then restarting the dead, because if cells in the defrosted organ are still viable the body is able to utilize the organ. This is also much closer to current medical technology such as organ transplants and the like.) 3.) Cryonics heavily relies on the speculative technology known as advanced molecular nanotech. a.) Nanotech as envisioned for this purpose has many single-points of failure all of which could result in the technology failing to work as hoped. b.) The nanotech required is so far outside of current science that trying to predict what it can do is a hard problem at best. 4.) Cryonics has many single-points of failure and many unresolved questions: A couple examples: a.) Is there anything fundamental about death the precludes the possibility of restoring life? b.) Is it possible to maintain self/person-hood by simply maintaing physical state integrity? c.) Is the general concept of organ preservation able to be scaled to entire bodies or is there a limit to what can be restarted? d.) Is a living organism required to overcome the effects of the cryopreservation? etc.

These facts I think cast enough doubt on the idea of cryonics to make it anything but an obvious choice. Further more having read the available work on the cryonics what is extremely clear is that nobody has a clue if this is anything more then a pipe-dream.

As to the continued point of the link "demands for particular proof" I have outlined my opinion on that. If someone cares to elucidate for me the writers authority on the issue fine otherwise its a dead horse no need to beat it further (ie not going to read it).

If you have some scholarly article you wish to present in favor of cryonics I would be pleased to read it.

Comment author: JoshuaZ 08 July 2010 01:20:16AM *  5 points [-]

I already stated that I disregarded the last link for lack of evidence that the source is trustworthy (published papers and the like).

I don't see where you said that. And even given that, I find that response to be deeply confusing. We are talking about this post http://lesswrong.com/lw/1rv/demands_for_particular_proof_appendices/) yes? That post has nothing to do with specific claims of evidence. It is a self-contained argument about what sorts of arguments are or are not valid when discussing cryonics, or for that matter, when discussing any future technology. I don't see what trustworthiness has to do with the arguments there. Can you point to specific claims in that post that you would want to be backed up by evidence that isn't there?

Actually to be fair cryonics has to many single points of failure yet to be avoided to make deciding about it any thing more then a total crapshoot.

I'll refrain from quoting The Princess Bride but what do you mean by "to be fair" in that sentence? Normally when that phrase is used people are mentioning an argument which goes against the position that they are arguing for, or to clarify that a position being argued against is not the position of some relevant source. How are you using that phrase?

In general, telling Bayesians that something is a "total crapshoot" isn't generally helpful. We can make estimates for technologies.

Who knows but this falls in the realm of a problem with to many unknowns making it impossible to answer. So I say anyone claiming otherwise is claiming based on blind faith not on reason.

But there are many things which aren't unknown. We have a pretty decent understanding of how brain tissue functions. We know that synapses (barring acousting fractures resulting in large sheering) are by and large intact. Many things aren't unknowns. And this really doesn't help given that even most proponents of cryonics agree that the chance of revival may not be very high. So where in any of that is there "blind faith?" Are you using the term "blind faith" in a non-standard fashion?

You guys like cryonics thats lovely I hope it works for you.

Another reason you are getting voted down may be the lack of grammar and spellchecking which reinforces the perception that you aren't putting much effort into your posts. One doesn't need perfect grammar and spelling. But many modern browsers have an option (often set as the default) so that words which are not in the spellchecker turn up with a red underline. "Thats" turns up red on Firefox for example. "That's" does not. Your sentence above could also use a few other punctuation marks. Two periods and a capitalization of the T would be nice.

Aside from the poor grammar, the most puzzling thing about this sentence is that it doesn't seem to fit in with your earlier attitude. I would find your remarks more believable if you switched from contempt to careful neutrally writing. But in this case, your sentence seems almost Pi radians from [your earlier position http://lesswrong.com/lw/2f5/cryonics_wants_to_be_big/28wx where you talked about "corpse popsicles" and talked about "popsicle people" being "e revived from popsicle land, which is the flip side of Mr Rogers neighborhood." Frankly, this looks like another attempt at emotionalism rather than rational argument, this time trying to appear like your attitudes are more sympathetic to pro-cryonics people than they are. Frankly, this attempt comes across as so clumsy it might be more damaging to the goal of getting people to listen to you than you would if you just kept up the "corpse popsicle" language.

0 karma means I can't vote you down but if I could I would.

"The last link you posted was especially unhelpful since I am inclined to discredit the source for reasons that I have already commented on."

" I find that response to be deeply confusing.

I assure you there is nothing confusing or emotional about this. You actually have totally missed the point but that's ok.

"Frankly, this attempt comes across as so clumsy it might be more damaging to the goal of getting people to listen to you than you would if you just kept up the "corpse popsicle" language."

I don't know why you are caught up on the corpse popsicle thing get over it don't like it not my problem.

The key point of my comment that you missed: to many single points of failure = a crapshoot when trying to be rational about something

Now since I can't do this in reality but if we were on google groups consider yourself plonked (ignored and disregarded because I have no patience for your further bewildered responses)

Comment author: Roko 07 July 2010 12:26:21AM *  7 points [-]

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 proposition of interest is true. The whole point of cryonics is as an ambulance ride to the future; to take advantage of the asymmetry between the technology needed to successfully preserve a patient (cryoprotectants, liquid nitrogen storage) and the technology needed to revive a patient (probably molecular nanotechnology).

Given that you don't currently have molecular nanotechnology, you can't reasonably expect to revive a cryonics patient today even given that they could in fact be revived using future molecular nanotechnology.

You are entitled to arguments, though not that particular proof, and cryonicists have done their best to provide you with whatever evidence can be obtained. For example:

A study on rat hippocampal slices showed that it is possible for vitrified slices cooled to a solid state at -130ºC to have viability upon re-warming comparable to that of control slices that had not been vitrified or cryopreserved. Ultrastructure of the CA1 region (the region of the brain most vulnerable to ischemic damage) of the re-warmed slices is seen to be quite well preserved compared to the ultrastructure of control CA1 tissue (24). Cryonics organizations perfuse brains with vitrification solution until saturation is achieved...

A rabbit kidney has been vitrified, cooled to -135ºC, re-warmed and transplanted into a rabbit. The formerly vitrified transplant functioned well enough as the sole kidney to keep the rabbit alive indefinitely (25)... The vitrification mixture used in preserving the rabbit kidney is known as M22. M22 is used by the cryonics organization Alcor for vitrifying cryonics subjects. Perfusion of rabbits with M22 has been shown to preserve brain ultrastructure without ice formation (26)."

Comment author: SamAdams 08 July 2010 01:18:17AM -8 points [-]

Yeah this is the wrong way to go:

Let's discuss how Roko went wrong when he made his comment:

"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."

Incorrect demanding further proof for an idea with as many single points of failure as cryonics is logical and sensible. The ability to make a rational decision means you need sufficient evidence of a sufficient quality to make you conclusions. Eliminate some more single points of failure from cryonics then maybe. Its like thinking you can solve a math problem with ten variables where you only have information and relations for two.

"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 proposition of interest is true. The whole point of cryonics is as an ambulance ride to the future; to take advantage of the asymmetry between the technology needed to successfully preserve a patient (cryoprotectants, liquid nitrogen storage) and the technology needed to revive a patient (probably molecular nanotechnology)."

Ok, so there are a couple giant single points of failure right there which cannot be overlooked. Nanotech needed can't do it yet and we still have so much work and so many problems yet to solve that to think we are going to get there is pure faith not a reasoned opinion.

To believe that cryonics is sufficient ambulance implies believing that: 1.) death in no way fundamentally and irreparably kills a human (proof not yet obtained) 2.) that the level of preservation is sufficient (partial proof kidney etc) 3.) that preserving the cells is sufficient assuming repair is possible to allow one to revive the individual without a loss of self (proof not yet obtained)

Of course there a more but here are three.

"Given that you don't currently have molecular nanotechnology, you can't reasonably expect to revive a cryonics patient today even given that they could in fact be revived using future molecular nanotechnology."

A completely irrational statement to many single points of failure that can totally derail the process.

"You are entitled to arguments, though not that particular proof, and cryonicists have done their best to provide you with whatever evidence can be obtained. For example:"

Thanks, I was going to have my opinions regardless of your permission. I read the stuff from the alcor website and the papers cited and I don't believe a single one of them demonstrates viability (eliminating enough single points of failure) to convince me that cryonics can be rationally decided upon or even rationally believed to be possible without a huge leap of faith.

"A study on rat hippocampal slices showed that it is possible for vitrified slices cooled to a solid state at -130ºC to have viability upon re-warming comparable to that of control slices that had not been vitrified or cryopreserved. Ultrastructure of the CA1 region (the region of the brain most vulnerable to ischemic damage) of the re-warmed slices is seen to be quite well preserved compared to the ultrastructure of control CA1 tissue (24). Cryonics organizations perfuse brains with vitrification solution until saturation is achieved..."

This is very different then taking a dead brain and re-activating it. Just because the cells are viable doesn't mean you can restart the neural processes once stopped. Not to mention there is a huge amount of work to prove that which could be derailed easily.

"A rabbit kidney has been vitrified, cooled to -135ºC, re-warmed and transplanted into a rabbit. The formerly vitrified transplant functioned well enough as the sole kidney to keep the rabbit alive indefinitely (25)... The vitrification mixture used in preserving the rabbit kidney is known as M22. M22 is used by the cryonics organization Alcor for vitrifying cryonics subjects. Perfusion of rabbits with M22 has been shown to preserve brain ultrastructure without ice formation (26).""

One organ revived and implanted in a living organism is a long way from some 100 year old corpse popsicle being revived from the dead. One in no way implies the other. (For gods sake have you ever actually studied biology)

In summary a swing and a miss from Roko.

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 decisions under uncertainty, one has to make do with the evidence that can be gathered at the time of decision (and there really is a wealth of such evidence in the case of cryonics). Do you disagree with this general principle or with this application, and if so, on what grounds?

Actually to be fair cryonics has to many single points of failure yet to be avoided to make deciding about it any thing more then a total crapshoot. For example advanced ideal nano-tech that you guys love to extol the benefits of may never come about. It may turn out that even with full cell repair there is no way to revive the individual. It could be that ones personhood and sense of self is lost in the process etc.

Who knows but this falls in the realm of a problem with to many unknowns making it impossible to answer. So I say anyone claiming otherwise is claiming based on blind faith not on reason.
