Good questions-usually when EAs talk about loss of civilization, they mean a loss of electricity/industry globally, or a loss of cooperation outside the tribe globally (loss of cities, the anthropological definition of civilization). One recent 80,000 Hours podcast guest estimated 10% chance of collapse of civilization with 2°C slow global warming. This has a survey with large variation in the percentage loss in value of the long-term future associated with full-scale nuclear war and with 10% agricultural shortfalls (e.g. regional nuclear war, such as India Pakistan). This has a poll with large variation in the percentage loss in the value of long-term future associated with either 10% or global loss of electricity/industry. This has a collection of existential risk estimates, and some relate to loss of civilization.

That's great that you are considering giving so much! When people say what percent of their income they are donating, usually they use the pretax income, which is the adjusted gross income (AGI) in the US. This is less than the total compensation because of things like benefits, some contributions to retirement, etc. I am not sure how stock options work, so hopefully someone else can join in on this. Unfortunately your calculator does not tell you the AGI, but you could probably find one that does. It seems to me that the calculator is giving broadly reasonable results. Basically, your net income doesn't decrease as much as your charity amount because of the tax advantage. It used to be that the maximum you could give with a federal tax advantage was 50% of AGI, but that got changed to 60% a couple years ago. And I've read that this year it is actually 100%. Of course even if the tax advantaged limit is 60% of AGI, you could still give more.

My philosophy is to earn like upper middle class, live like middle class, and donate like upper class. One can typically accomplish this by roughly maintaining the consumption per person that one has earlier in life (e.g. college or grad school). Sure, there is temptation to have consumption creep as is happening in most of one’s peers, but it is not technically difficult like rock climbing, or nearly as bad as living with hunger on a diet. An exception for this being effective may be if one’s consumption is visible to those who determine how fast one advances in one’s career, and they don’t appreciate one’s choosing of charity.

Thanks for the useful model. I think you should report ranges, because one would expect with the one-year multiplier of 1.01, that you would get a 10 year multiplier of 1.01^10 = 1.1. Even with the ranges, it seems counterintuitive to me. If you take the 5th percentile of a 0.84 multiplier, that gives a 10 year 0.17 multiplier, which is close to the Guesstimate result. However, if you take the 95th percentile of a 1.3 multiplier, that gives a 10 year multiplier of 14, which is very different from the Guesstimate value of about 1000. I assume this is because of the fat tail. This shows that this is a high risk strategy from the perspective of the donor-more than 50% of the time they have a smaller impact by investing. But they have some chance of having an enormous impact with investing.

Thanks for the valuable post. I think it is possible that insects could become competitive with fish meal, and both are high-protein. But I don’t think they could be competitive with low protein feed, because basically you are feeding them low protein feed (animal waste is the possible exception, but that could be fed to non-insects as well). What is the current typical cost per dry kilogram wholesale of insects for feed? When I checked, it was ~$9/kg wholesale, which is far higher than animal feed at ~$0.5/kg. Your source for the two units of feed for one unit of insects did not specify units, so I went to the original, and it looks like it is comparing dry feed and wet animal. This makes sense because if this were based on calories, it sounds too high even if you had ideal circumstances (no diseases, cannibalism, etc.). This is because insects typically cannot synthesize protein, so if they are 50% protein and the feed is 10% protein by calories, maximum conversion efficiency would be 20% even if they emitted no nitrogen in their waste.

1. Good point
2. Without sustained protective measures, we only get herd immunity after a certain number get infected, roughly 50% for R0 = 2. So I don't think short-term measures alone (e.g. earlier travel or event banning) would impact this.
3. Again, you need sustained efforts, not just a difference in short-term effort to flatten the curve.
4. Good point
5. Without 4, it appears that the outbreak would have already peaked by the time we develop, test, and scale up a vaccine
6. This is possible, but most think other countries will not take as extreme measures

So overall, this does give significant probability that short-term actions could have high impact, so they do look worth doing.

Comment by denkenberger on Quantifying lives saved by individual actions against COVID-19 · 2020-03-08T18:59:48.041Z · score: 3 (2 votes) · EA · GW

I agree that if we have sustained protective measures, it would not only lower the peak but also reduce the total number of people exposed. However, I am defining a short-term action as doing something we would not normally do in the next few weeks, like canceling a conference or early travel bans. I think this would delay the peak, but it's not clear to me that the peak would be appreciably lower. Furthermore, this says there are about 60,000 full function ventilators and 160,000 total ventilators. If 10% percent of people are infected at the peak and 3% of those require ventilation, that would be 1 million requiring ventilation. So even in the US, and with moderate protective measures, it looks like most people would not be getting the ventilation they need (though lowering the peak will still help somewhat). Of course if the protective measures actually stopped the spread early, then that would be a big benefit.

Thanks for making your model explicit. See my comment here. Basically, the crux is that if there is going to be global spread, it could be that the final mortality is independent of short-term actions. It would be great for an epidemiologist to weigh in.

I agree that it is useful to make simple models. The consensus appears to be that there will be a global spread, so then it appears that short-term actions could have very high impact. However, one could also argue that then the end state is going to be the same, so that would mean short-term actions would have no impact. It is true if social distancing (physical distance, handwashing, gloves, masks, etc.) is maintained for the entire pandemic, then R0 falls below one sooner, so fewer people get the disease. You can see a model of this here. On the 80,000 Hours podcast, they say that reducing travel out of the place of origin by 90% in the beginning only delays the outbreak 3 weeks, likely not enough time to get a vaccine. So which one is right, a huge impact due to short-term actions or basically nothing?

Yes, this morning in Fairbanks it was -32F (-36C)!

Though many of the recommendations seem like common sense in retrospect, the reality is that these interventions are relatively neglected. We would have been better off if we had done some planning ahead of time about how to scale up personal protective equipment (PPE) such as masks. Furthermore, common sense varies. For some, it is common sense that a mask will protect you from illness, but people do not realize that the pore size of a simple polymer surgical mask is significantly larger than most evaporated cough/sneeze droplets. At the other end of the spectrum, common sense might lead you to believe that an improvised fabric mask would be ineffective because the pore size is larger than the typical surgical mask made of polymer. And indeed the median particle that is sneezed would go through a fabric mask. However, when you look at the droplet size distribution, the majority of mass (and therefore viruses) are actually contained in the larger droplets that would be stopped by a fabric mask. Similarly, common sense might lead you to believe that a glove needs to be rubber because that is how we get most of them. But if dexterity is not critical, one can use plastic (e.g. garbage bags). Another piece of common sense that I had before embarking on this project was that this PPE would just slow down the spread, but eventually everyone would get the disease, so the mortality at the end would be the same (assuming a vaccine is not developed in time). But in reality, since people who have had the disease generally have immunity, the number of people that infected person spreads to eventually falls below one, and the virus dies out, not infecting everyone. So these simple PPE interventions could actually significantly reduce overall mortality. Furthermore, if people can do more distancing early on, the spread of the virus could be stopped early, preventing a pandemic. So there really is a lot that we can do on the non-medical side.

This is fascinating work! Small comment: you mentioned that the practical lens concentration limit is about 50% of the intensity at the surface of the sun and that we likely achieved that 1000 years ago. But then you say that magnesium combustion reaches 3370 Kelvin. Since the sun is about 5800 Kelvin and the total radiation goes with the fourth power of the absolute temperature, that would mean magnesium would only be 1/9 the intensity of the sun. So that would mean that magnesium combustion would not have surpassed a good magnifying glass.

Thanks for writing this up. I would love to see more detail in general, but in particular on this point:

The highest leverage point for intervention in a potential post-collapse environment would be at the state level. Individuals, even wealthy individuals, lack the infrastructure and human resources at the scale necessary to rebuild effectively. There are some decent mitigations possible in the space of information archival, such as seed banks and internet archives, but these are far less likely to have long term impacts compared to state efforts.

So you're assuming that the states still function after the collapse? What do you think they would do and what would you like them to do differently? What do you think about interventions post catastrophe to reduce the likelihood of collapse? For instance, there is the idea of a backup shortwave radio system that I mentioned in our joint salon that would not require a state.
Why is the Internet archive (I assume printed out) not important, because there would already be enough information preserved in books? I don't think that would apply so much in the case of seeds because we might not be able to continue growing the high-yielding varieties that are dependent on fertilizer and pesticides.

I think this is important to investigate given the high mortality. I noticed that you ignored the savings in fuel. My understanding was that this could be quite significant and the stoves could pay for themselves either in saved fuel cost or saved opportunity cost of time from gathering the fuel. If this were true, you might be able to argue that the life savings and climate benefit came at zero cost. You would still have the issue that people are not willing to pay for them, perhaps because they have a high discount rate. Loans might ameliorate this.

I think most nuclear winter scenarios also have less than a 90% food reduction impact

The Open Philanthropy funded nuclear winter project will soon have an estimate of global agricultural impact, but I think without relocation of crops, 90% production loss is plausible. How that translates into mortality is complicated. It may be possible to relocate crops towards the equator, but the likelihood of that happening would depend on preparation ahead of time for coordination, etc. On the positive side, we have some food storage, which has the potential to take ~10% of the population through a nuclear winter with complete agricultural collapse if perfectly protected. However, on the other extreme, if food were distributed equally, then perhaps a 70% food supply reduction would mean everyone starves. The reality is likely to be between these extremes of perfect protection and equal distribution. Of course the situation changes dramatically if we can produce alternative foods.

I agree that absolute impact is the better way of looking at this. You talk about the original pitch of EA of donating 10% of your salary and saving quite a few lives. But now that same person can donate the same amount of money to the long-term future and potentially save orders of magnitude more lives in expectation. So I think EA has gotten more exciting. I could see if someone has inflexible career capital in the global poverty or animal space and little ability to donate and became convinced of the value and tractability of the long-term future, that this could decrease one's relative impact. But I think this is less common than the case of being able to pivot (at least somewhat) towards higher impact. So I think a change in enthusiasm is more related to general trends with age and movements, rather than a change in perception of relative impact.

Welcome to the EA Forum! Kudos to you for your generosity! You’ve probably already joined Giving What We Can, but you may also be interested in Bolder Giving (giving high percentages, but not focused on effective giving).

Since you can deduct state taxes and interest on a mortgage, I would guess you are already exceeding the $14,000 standard deduction. So then I think it would be important to donate every year to make sure you are saving taxes on the money you make in the top bracket. Here is a post that might be helpful. There are also quite a few posts (e.g. this recent one) on investing with an EA mindset.

Rural to urban migration: Unskilled (subsistence) farmers migrate to cities and start working in factories. Over night, this increases their productivity many times over.

Perhaps tangential, but unless the urban workers are fed by imports, in order to allow rural to urban migration, the country needs agricultural improvements so that people can feed a lot more than themselves. So I think the green revolution technologies of fertilizer, pesticides, and improved crop varieties (mentioned by the OP) are quite important beyond the direct food supply improvement, and the penetration of these is much lower in Africa.

Wealth is accumulated money, while GDP is per year. Debt is also accumulated, while deficit is per year.
