Milan Griffes on EA blindspots

Thank you Gavin (algekalipso here).

I think that the most important EA-relevant link for #1 would be this: Logarithmic Scales of Pleasure and Pain: Rating, Ranking, and Comparing Peak Experiences Suggest the Existence of Long Tails for Bliss and Suffering 

For a summary, see: Review of Log Scales.

In particular, I do think aspiring EAs should take this much more seriously:

An important pragmatic takeaway from this article is that if one is trying to select an effective career path, as a heuristic it would be good to take into account how one’s efforts wou

Cluster Headache Frequency Follows a Long-Tail Distribution

This post significantly adds to the conversation in Effective Altruism about how pain is distributed. As explained in the review of Log Scales, understanding that intense pain follows a long-tail distributions significantly changes the effectiveness landscape for possible altruistic interventions. In particular, this analysis shows that finding the top 5% of people who suffer the most in a given medical condition and treating them as the priority will allow us to target a very large fraction of the total pain such a condition generates. In the case of clus... (read more)

Treating Cluster Headaches Using N,N-DMT and Other Tryptamines

As explained in the review of Log Scales, cluster headaches are some of the most painful experiences people can have in life. If a $5 DMT Vape Pen produced at scale is all it takes to fully take care of the problem for people sufferers, this stands to be an Effective Altruist bargain.

In the future, I would love to see more analysis of this sort. Namely, analysis that look at particular highly painful conditions (the "pain points of humanity", as it were), and identify tractable, cost-effective solutions to them. Given the work in this area so far, I expect... (read more)

Using Ibogaine to Create Friendlier Opioids

Most people who know about drugs tend to have an intuitive model of drug tolerance where "what goes up must come down". In this piece, the author shows that this intuitive model is wrong, for drug tolerance can be reversed pharmacologically. This seems extremely important in the context of pain relief: for people who simply have no option but to take opioids to treat their chronic pain, anti-tolerance would be a game-changer. I sincerely believe this will be a paradigm shift in the world of pain management, with a clear before-and-after cultural shift arou... (read more)

Logarithmic Scales of Pleasure and Pain: Rating, Ranking, and Comparing Peak Experiences Suggest the Existence of Long Tails for Bliss and Suffering

I would like to suggest that Logarithmic Scales of Pleasure and Pain (“Log Scales” from here on out) presents a novel, meaningful, and non-trivial contribution to the field of Effective Altruism. It is novel because even though the terribleness of extreme suffering has been discussed multiple times before, such discussions have not presented a method or conceptual scheme with which to compare extreme suffering relative to less extreme varieties. It is meaningful because it articulates the essence of an intuition of an aspect of life that deeply matters to ... (read more)

Comments for shorter Cold Takes pieces

Hi Holden!

I am happy to see you think deeply about questions of personal identity. I've been thinking about the same for many years (e.g. see "Ontological Qualia: The Future of Personal Identity"), and I think that addressing such questions is critical for any consistent theory of consciousness and ethics.

I broadly agree with your view, but here are some things that stand out as worth pointing out:

First, I prefer Daniel Kolak's factorization of "views of personal identity". Namely, Closed Individualism (common sense - we are each a "timeline of experience"... (read more)

A Primer on the Symmetry Theory of Valence

People are asking for  object-level justifications for the Symmetry Theory of Valence:

The first thing to mention is that the Symmetry Theory of Valence (STV) is *really easy to strawman*. It really is the case that there are many near enemies of STV that sound exactly like what a naïve researcher who is missing developmental stages (e.g. is a naïve realist about perception) would say. That we like pretty symmetrical shapes of course does not mean that symmetry is at the root of valence; that we enjoy symphonic music does not mean harmony is ... (read more)

Thanks Andrés, this helped me get oriented around the phenomenological foundations of what y'all are exploring.
It sounds like you're saying we all need to become more suggestible and just feel like your theory is true before we can understand it. Do you see what poor reasoning that would be?
Does Critical Flicker-Fusion Frequency Track the Subjective Experience of Time?

Thank you for this very insightful and information-dense article!

My sense is that critical flicker fusion is more about sampling rate than about phenomenal time per se. And also, that just because time feels slow doesn't mean you are actually getting more experience on the whole. The critical issue here is the difference between phenomenal time and physical time (as covered in the Pseudo-Time Arrow).

In particular, one could e.g. have 1000 experiences per second and think that you are only having one experience per second (e.g. lots of very short pseudo-tim... (read more)

Consciousness research as a cause? [asking for advice]

I don't see anything like that from QRI either, although someone can correct me if I missed it.


In Principia Qualia (p. 65-66), Mike Johnson posits:

What is happening when we talk about our qualia? 

If ‘downward causation’ isn’t real, then how are our qualia causing us to act? I suggest that we should look for solutions which describe why we have the sensory illusion of qualia having causal power, without actually adding another causal entity to the universe.

I believe this is much more feasible than it seems if we carefully examine the exact sense ... (read more)

1Steven Byrnes1y
OK, if I understand correctly, the report suggests that qualia may diverge from qualia reports—like, some intervention could change the former without the latter. This just seems really weird to me. Like, how could we possibly know that? Let's say I put on a helmet with a button, and when you press the button, my qualia radically change, but my qualia reports stay the same. Alice points to me and says "his qualia were synchronized with his qualia reports, but pressing the button messed that up". Then Bob points to me and says "his qualia were out -of-sync with his qualia reports, but when you pressed the button, you fixed it". How can we tell who's right? And meanwhile here I am, wearing this helmet, looking at both of them, and saying "Umm, hey Alice & Bob, I'm standing right here, and I'm telling you, I swear, I feel exactly the same. This helmet does nothing whatsoever to my qualia. Trust me! I promise!" And of course Alice & Bob give me a look like I'm a complete moron, and they yell at me in synchrony "...You mean, 'does nothing whatsoever to my qualia reports'!!" How can we decide who's right? Me, Alice, or Bob? Isn't it fundamentally impossible?? If every human's qualia reports are wildly out of sync with their qualia, and always have been for all of history, how could we tell? Sorry if I'm misunderstanding or if this is in the report somewhere.

Cost-Effectiveness of Air Purifiers against Pollution

Now that the California fires are raging, it may be time to bring up a few additional reasons why HEPA filters make a lot of sense. I don't know how much this changes the cost-benefit analysis, but I think it is important to take into account:

1) Right now the PM2.5 outside my apartment is 230. Inside it's 40. A week ago the PM2.5 was 100, and inside it was 8. By having a HEPA filter inside, I've been seeing reductions of PM2.5 between 80% and 90%. I also saw this two years ago, and it's been a rather consistent pattern.

Making discussions in EA groups inclusive

Like many other problems that EAs are aware of, the particular incident you described comes from an outlier that drives the mean significantly forward (I of course know who you are talking about, and the fact that many who've been in EA for a long time know as well should indicate that this is both rare in terms of % of people yet perhaps not that rare in terms of % of drama it accounts for).

The key insight here is that the long-tail matters. As a rough prior we could anticipate that 80% of the drama will come from 20% of people (in my experience this... (read more)

*Logarithmic Scales of Pleasure and Pain*

Recall that while some distributions (e.g. the size of the leaves of a tree) follow a Gaussian bell-shaped pattern, many others (e.g. avalanches, size of asteroids, etc.) follow a long-tail distribution. Long-tail distributions have the general property that a large fraction of the volume is accounted for by a tiny percent of instances (e.g. 80% of the snow that falls from the mountain will be the result of the top 20% largest avalanches).

Keeping long-tails in mind: based on previous research we have conducted at th... (read more)

This sounds really interesting. I looked into QRI once before and was concerned that I couldn’t find much mainstream recognition of their work. Would you know how much mainstream recognition has QRI’s work received, either for this line of research or others? Has it published in peer-reviewed journals, received any grants, or garnered positive reviews from other academics? Could you point me to any information here? Thanks, and looking forward to hopefully hearing this talk.
What are the key ongoing debates in EA?

Whether avoiding *extreme suffering* such as cluster headaches, migraines, kidney stones, CRPS, etc. is an important, tractable, and neglected cause. I personally think that due to the long-tails of pleasure and pain, and how cheap the interventions would be, focusing our efforts on e.g. enabling cluster headaches sufferers to access DMT would prevent *astronomical amounts of suffering* at extremely low costs.

The key bottleneck here might be people's ignorance of just *how bad* these kinds of suffering are. I recommend reading the "long-tails of ... (read more)

Logarithmic Scales of Pleasure and Pain (@Effective Altruism NYC)

Thank you! I just left a reply to your comment. Here's a summary of the core claim:

In this account, the fact that people would naturally and spontaneously use a logarithmic scale to report their level of pain is a simple implication of the fact that you can only definitively tell that "the pain got worse" when it got 10% worse and not when it became 1 unit worse (which soon becomes hard to notice when you talk about experiences with e.g. 1000 pain units per second).
Logarithmic Scales of Pleasure and Pain: Rating, Ranking, and Comparing Peak Experiences Suggest the Existence of Long Tails for Bliss and Suffering

Hey Michael,

Thank for commenting. First of all I agree that the claims of (A) and (B) do need to be distinguished, and I admit I didn't make that conceptual distinction very clear in the article. I agree that the most important takeaway from the piece is (B), and I also think that this alone is already enough to challenge EA's prioritization methods (i.e. ultra-painful experiences are completely flying under the radar from the point of view of QALYs and similar metrics; reducing the incidence of cluster headaches, migraines, kidney stones, etc. c...

Is pain just a signal to enlist altruists?

Thanks for writing this.

How would this model explain Cluster Headaches? They are not particularly more incapacitating than migraines, yet they are (possibly literally*) thousands of times more acutely painful than them. What is the role of this X1000 multiplier on phenomenal pain in such cases? As far as I can tell, in the ancestral environment nobody could have done anything to help you if you were having a Cluster Headache, and your chances of reproduction seem to be the same whether that pain was a thousand times less bad (which would still be VERY bad,...

One possibility, if this theory is correct, is that cluster headaches are a spandrel, i.e. a (very unfortunate) unintended side effect of the pain system being accidentally fired in a case when it isn't beneficial for it to be but doesn't get selected out because it doesn't have much of an impact on differential reproduction rates.

Another is that causality is slightly different, pain is amped up in some cases to elicit altruism, but the mechanisms of pain are "lower in the stack" and so can be triggered by things other than those c... (read more)

Cluster Headache Frequency Follows a Long-Tail Distribution

That's a good point, thank you. We should distinguish between lifetime use and current use in future surveys. Perhaps even asking whether "they worked the first time you used them" to see if people who currently use them had a better reaction to their first try relative to those who did try them at some point but do not currently use them.

I would add that other reasons why people might have used them in the past but don't currently include "can't access it now", "too afraid of legal repercussions", and "soc... (read more)

Cluster Headache Frequency Follows a Long-Tail Distribution

Depends on context. In most cases the 'we' refers to my team and I at the Qualia Research Institute. For example: "Since a number of interviews we’ve conducted have shown that even sub-hallucinogenic doses of DMT can abort cluster headaches" refers to QRI (with other members of the research group having conducted such interviews).

I should note that the word is also used in the 'didactic we' sense a number of times (as in "we will explore the era of the dinosaurs together" in a National Geographic documentary).

According to "Right Concentration: A Practical Guide to the Jhanas" by L. Brasington and "The Mind Illuminated" by Culadasa, it is feasible to achieve Jhana states within two years of dedicated practice. This entails a few hours of meditation a day and attending at least one 9-day retreat over the course of this time period. The books explain in detail how to get there in a very practical and no-nonsense way.

Cause X Guide

To zoom in on the "logarithmic scales of pleasure and pain" angle (I'm the author), I would say that this way of seeing the world suggests that the bulk of suffering is concentrated on a small percentage of experiences. Thus, finding scaleable treatments specially for ultra-painful conditions could take care of a much larger percent of the world burden of suffering than most people would intuitively realize. I really think this should be up in the list of considerations for Cause X. Specifically:

Logarithmic Scales of Pleasure and Pain: Rating, Ranking, and Comparing Peak Experiences Suggest the Existence of Long Tails for Bliss and Suffering

Hey Soeren!

I would disagree for the following reason. For a group to contribute equally it needs to have both its average and its size be such that when you multiply them you get the same value. While it is true that people at the 50% percentile get 1/10 of the people at the 90% (and ~1/50 of the 99%), these do not define groups. What we need to look at instead is the cumulative distribution function:

The bottom 50% accounts for 3.17% of incidents

The bottom 90% accounts for 30% of incidents

The bottom 95% accounts for 43% of incidents

That fair, I made a mathematical error there. The cluster headache math convinces me that a large chunk of total suffering goes to few people there due to lopsided frequencies. Do you have other examples? I particularly felt that the relative frequency of extreme compared to less extreme pain wasn't well supported.
Logarithmic Scales of Pleasure and Pain: Rating, Ranking, and Comparing Peak Experiences Suggest the Existence of Long Tails for Bliss and Suffering

Hi! Thank you for elaborating on what your question is :)

"Bulk" is indeed a very ambiguous term. Would you say 80% is "the bulk"? And 20% is "a small percentage"? If so we would be in agreement. If not, it is more of a wording issue than a matter of substance, I think.

Good catch that the numbers I provided would suggest a power law that just keeps going (e.g. similar to St. Petersburg paradox?). If we use the Cluster Headache dataset, the numbers are:

50% percentile experiences 70 CH/year

80% percentile experiences 365 CH/year

Your 4 cluster headache groups contribute about equally to the total number of cluster headaches if you multiply group size by # of CH's. (The top 2% actually contribute a bit less). That's my entire point. I'm not sure if you disagree?
Logarithmic Scales of Pleasure and Pain: Rating, Ranking, and Comparing Peak Experiences Suggest the Existence of Long Tails for Bliss and Suffering

Adding to what Lucas mentioned (how we are motivated in part by longing/addiction for strong rewards): Suffering and negative reinforcement are correlated but are by no means the same thing. In the case of extreme suffering, there seems to be a point where the pain has already maxed out in terms of negative reinforcement capacity, and anything above it is just senseless suffering. Cluster headaches would not cause any less behavioral suppression if they were 10 or even 100 times less painful. Likewise, our ability to reason about pain and pleasure is limit... (read more)

Logarithmic Scales of Pleasure and Pain: Rating, Ranking, and Comparing Peak Experiences Suggest the Existence of Long Tails for Bliss and Suffering

The short answer is - extreme pain is vastly more common than is generally believed. Statistics such as 20% of people in the USA experience chronic pain, with 8% experiencing high-impact chronic pain (interferes with most aspects of life). If indeed we live in Lognormal World, we can expect that the median person will probably have relatively low acquaintance with extreme suffering (until old age), but that the people in the top 10% of sufferers will have 10X the amount, and people in the 99% will have 100X the amount. If we take a person-neutral point of ... (read more)

To the second half of your comment, I agree that extreme suffering can be very extreme and I think this is an important contribution. Maybe we have a misunderstanding about what 'the bulk' of suffering refers to. To me it means something like 75-99% and to you it means something like 45% as stated above? I should also clarify that by frequency I mean the product of 'how many people have it', 'how often' and 'for how long'. "the people in the top 10% of sufferers will have 10X the amount, and people in the 99% [I assume you mean top 1%?] will have 100X the amount" I'm confused, you seem to be suggesting that every level of pain accounts for the _same_ amount of total suffering here. To elaborate, you seem to be saying that at any level of pain, 10x worse pain is also 10x less frequent. That's a power law with exponent 1. I.e. the levels of pain have an extreme distribution, but the frequencies do too (mild pains are extremely common). I'm not saying you're wrong - just that I've seen also seems consistent with extreme pain being less than 10% of the total. I'm excited to see more data :)
4Ozzie Gooen3y
Related; I think people do directly make choices that hint at this. Examples would include spending large numbers of resources on drugs and sex on the positive side, and (I'd expect) large numbers of resources to avoid torture / short-duration-but-painful situations. Listening to the Feeling Good podcast, one common thing is that many people in America have deep fears of becoming homeless, and work very hard to avoid that specific outcome. Much of this is irrational, but some quite justified.
Logarithmic Scales of Pleasure and Pain: Rating, Ranking, and Comparing Peak Experiences Suggest the Existence of Long Tails for Bliss and Suffering

Thank you!

The article does focus on the long-tail of intensity and quality of both pleasure and pain rather than frequency. That said, it discusses the Lognormal World as a general principle, which would also predict that the frequency of pain or pleasure would follow a long-tail in addition to their intensity and quality.

This is backed up by the previous article "Cluster Headache Frequency Follows a Long-Tail Distribution", where we analyzed a survey about Cluster Headache frequency among sufferers, and showed it followed a long-tail (with stati... (read more)

Thanks. I was actually asking about a different frequency distribution. You're talking about the frequency of extreme pain among people with extreme pain which has no bearing on the quote above. I'm talking about the frequency of extreme pain experiences among all pain experiences (i. e. is extreme pain it lmuch less prevalent). Hence the example about mild discomfort.
Cluster Headache Frequency Follows a Long-Tail Distribution

It's great that it works for some people, some of the time. In absolute terms, it is a massive good, so it should be promoted more. Pragmatically it might make sense to emphasize it right now given the low probability that DMT will be approved as a treatment in the next few years, so until then Emgality should be discussed more. That said, yes, in terms of % relief it still is in a completely different class than DMT. That is, it tends to reduce incidence rather than get rid of them, and it is only approved for episodic (rather than chronic) CHs, which account for a relatively small % of the number of CHs experienced, as described in this article (due to the long-tail).

Cluster Headache Frequency Follows a Long-Tail Distribution

In the article specifically about N,N-DMT as a possible treatment for CHs, Quintin added a rough QALY calculation (I should add that any QALY estimate concerning CHs and other ultra-painful disorders will typically severely underestimate the value of the interventions, given the logarithmic nature of pain scales):

9Ozzie Gooen3y
Thanks! Some quick thoughts: 1. One quick way to get people to not take you seriously is with a bad cost effectiveness estimate. There's a much bigger risk of doing a sloppy/overconfident job than benefit of having a high number at the end of it (in EA circles). Also, there is a reputation of these estimates to both produce amazing numbers and also be very wrong, so while I support attempts, I'd also recommend lots of clarification, hedging, and consideration of ways the number could be poor. I think the default expectation is for the number to not be great; but even if the median isn't good, it's possible upon further investigation it could be better than expected, which could be quite worthwhile. 2. "to reach all chronic sufferers" -> I'd recommend targeting 30%-60% of sufferers. The last several percent would be much more expensive. 3. I'm quite skeptical of the click -> cure stats in particular. For-profit websites often have a 1% rate of people who go from click -> purchase, and this could be a pretty significant amount of work to purchase. 4. Is this equation taking into account that the "cure" could last for many years? Would the result be in "QALYs per year"? 5. I'm sure you've answered this elsewhere, but why the American focus? Would it be possible in India or similar? 6. This estimation seems like something that Charity Entrepreneurship would have a lot more experience in. The program seems quite similar to some of their others. 7. I'd suggest reading up on the mini-fiasco of the leafletting research, if you haven't yet. Just make sure not to make some of the mistakes made around that. Some context: [] https://acesounde
Cluster Headache Frequency Follows a Long-Tail Distribution

I completely agree that the members of a cluster headache subreddit or facebook group are not necessarily representative, and in fact quite likely not representative at all.

I think that the conclusion that the distribution follows a long-tail regardless is still accurate.

Get-Out-Of-Hell-Free Necklace

Let's say "the typical pain of the top 5% most painful of the cases of a given condition".

My sense is that the pain scale is exponential. Let's say that kidney stones rank on average at a 7/10 level with a standard deviation of 1. In that case, about 2% of the kidney stone cases are a 9/10, which might be hundreds of times more painful than the 7/10 typical case. In other words, you can't really judge how many hell-seconds a given condition contributes by observing a *median* case... you need either the average or to look at the more painful side of it.

It’s just that your first comment sounded a bit like you’re implying that 10% of the population suffers from excruciating kidney stones. With your estimated numbers (10% of population affected at some point in their lives, 2% of cases at 9/10 on the pain scale), it would be more like 0.2%. That’s probably still a lot if you multiply by the world population and total pain episode lengths. I don’t know how long such a case typically lasts with modern medical care, but plenty of people don’t have access to it. Of course, this all depends on whether the 2% number is a reasonable estimate, and whether the pain scale is exponential. But my guess is that a better strategy will probe better medical prevention and treatment of underlying causes in most cases. After all, flooding the USA with powerful painkillers hasn’t exactly been a boon to the nation (see opioids).

I looked up CRPS and kidney stones, and it looks like both of them have relatively mild symptoms in most cases. Are you sure that this isn’t a case of conflating the pain of the most extreme cases and the prevalence of all cases? You’re right about the 8% figure for chronic severe pain, though. []
Get-Out-Of-Hell-Free Necklace

For context, this post is motivated by the realization that pain-scales are logarithmic compressions of what is probably an exponentially-increasing capacity for pain and suffering in sentient beings.

I've suggested something similar for happiness ( [(] ). If you don't want to introduce the weird asymmetry where negative counts and positive not, what you get out of that could be somewhat surprising - it possibly recovers more "common folk" altruism where helping people who are already quite well off could be good, and if you allow more speculative views on the space on mind-states, you are at risk of recovering something closely resembling some sort of "buddhist utilitarian calculus".
