Looks good from a quick read-through.

To make an obvious point, as relevant information (including about new charities/causes) will presumably improve a lot over the next 5 years, there seems a case for updating your recommendation annually rather than the donors committing upfront to donating 5 years' worth to particular charities (if that was the idea).

Depending to some extent on whether a 5-year commitment is essential for the programmes being donated to. If it is, a middle way might be to commit upfront to donating for 5 years subject to the programmes achieving XYZ goals, to be independently assessed each year.

Another obvious point (which you mention of course): the extremely wide range of the TaRL and salt iodization cost-effectiveness figures, from far below 1 (Founders Pledge estimate) to far above, would give me concerns as a donor that these are poorly understood interventions.

There's also the complication that by deciding to protest, individuals incur a non-negligible personal cost (in time and risk), but only make a tiny difference to the size & hence effectiveness of the demonstration. Also any benefit arising mostly accrues to others. All that on top of the risk of you spreading the virus to others.

All told, it's far from clear it's worth people's while to demonstrate, even for major issues like this one. It depends on things like the size of the demonstration and your degree of altruism. I did a rough model of this a while back (excluding the virus spreading affect):

Indeed, I looked at Trump's approval rating over time and it's been about average for US presidents with little pandemic effect. Possibly the US is a bit of an outlier in this regard though, or it's a bit early for an assessment.

Because the ultimate Covid death toll will be a stark, objective measure of performance relative to other countries, I suspect later in the year it will be harder for voters anywhere to maintain illusions about how well or badly their country has handled the pandemic. (That said, much is not really down to the leaders, as no-one can really be expected to have known how best to handle it, given the limited information early on and the variety of strategies that have been tried. I have little doubt though that Trump's decision-making has been particularly poor.)

Indeed I think it will accelerate this issue, though maybe not resolve it.

In the UK, and no doubt elsewhere, universities have cancelled courses for the rest of the year, or are making them online-only, but refusing to refund students; which will make students acutely aware of what value for money they're getting, or not.

That said I did read somewhere the observation that as degrees are as much about status & signalling as actual learning, it may make little difference. People will still prefer the prestige of an Ivy League or Oxbridge education if they can get it. That said, that prestige is rather bound up with physical attendance in grand surroundings, surrounded by top-notch professors etc.

A significant further thought:

The above calculation is done on life expectancies, treated as expected utilities; but human psychology doesn't work like that:

Arguably in Chris's particular case she may lose somewhat less than half her quality of life by conforming with the lockdown. In which case her behaviour looks irrational in life expectancy terms.

But Chris's behaviour is rational if she is risk-seeking. She prefers gambling her life (and perhaps others') by going to the beach, to the alternative of suffering a sure loss of quality of life by staying at home. This is normal behaviour in prospect theory - the same as a 'desperado' who, faced with arrest and inevitable jailtime, prefers the higher risk, less certain, lower expected utility option of stealing a car, shooting at cops etc. in the hope of getting away.

I.e. Chris, a 75-year-old desperado, is risking death to avoid imprisonment (and for some people, solitary confinement).

Layard is one of the top happiness economists.

Indeed the Guardian review of the book was dreadful. I almost wrote a point-by-point refutation of it (but no-one would read it). Turns out the reviewer is a self-described Marxist with a website called 'Leninology' so has a political axe to grind. As is hinted at towards the end of the review - for Layard advised the Blair government (on increasing mental health funding), and Blairites are the enemy.

Quite why a national newspaper would commission & publish such a misleading, bilious, partisan piece is beyond me.

Presumably they need to keep public transport operating for key workers, e.g. medical staff, supermarket staff etc. So if it's available then others will use it to get to parks.

Yes there's lots of research & data on this, particularly in recent years. The best summary is the new book Can We Be Happier? by Richard Layard. The largest factors (from memory) are health (especially mental - much larger than physical health), not being unemployed, having a partner, income. The most common measures are happiness and satisfaction with life, on a 0-10 self-reported scale.

Indeed people may lack perspective; so there's lots of work on how objective these self-reports are, what precisely they measure, whether they are absolute or relative to other people (in the same city or country) or relative to people's own past or whatever. I think the current consensus is that they are largely absolute measures.

Not sure (without looking up) what magnitude of changes to someone's life it would take to halve these numbers, but I have little doubt depression could do it.

Also (on a slightly technical point) most people reckon there are states worse than death, so death should be located not at 0/10 but maybe around 2/10. Which means halving your quality of life as compared with death (as an alternative) would only require a reduction from say 8/10 to 5/10 (since 5/10 to 2/10, the same distance, is a reduction to death).

Interesting and curious. I wonder if this is partly due to health only being one aspect of quality of life (happiness/life satisfaction).

Also I wonder whether the framing of the question is important. People have trouble thinking about this stuff clearly.

More understandable with $ trade-offs (people being funny about money).

Well, the specific caller in question aside, a fall from 8/10 to 4/10 (on a happiness or life satisfaction 0 to 10 scale) is plausible for a significant minority of people, e.g. if you're elderly and live alone and have nothing much to occupy you indoors. In the UK (more so in some other countries) you're not allowed out to relax; you need to be exercising, e.g. walking, not sitting on a bench or whatever (and police in my area are enforcing this); and the guideline is max 1 hour per day. And many with underlying health conditions in the UK are being told not to go out at all.

If this tipped you into depression, which it might with some, that could easily cause a fall from 8/10 to 4/10 or 6/10 to 3/10.

Of course the precise numbers are not really the point - I was just wanting to illustrate that the loss in quality of life can be large and of a similar scale to loss of longevity, so far from negligible.

I suspect also that if you're elderly and may only have a few years of life left then you put a very high value on maintaining your regular activities, maybe weighting quality of life rather higher than quantity (no doubt there is research on this). Hence why when very ill they sometimes forego treatment, choose to die sooner at home rather than be kept alive in hospital, etc.

The comparison is with her not going to the beach, socializing etc. for a year (rather than one-off), which I'm arguing could well halve her quality of life, so be equivalent to losing 0.5 years of life expectancy.

I assume the concerns about people visiting open spaces - even if social distancing - are largely about the other associated risks, from people using public transport to get there, going into shops to buy sandwiches/drinks, etc.

OK, well reworking the numbers with a 2/10 neutral point (and Imperial's latest figures as noted below):

Death is now a fall from 5.17 to 2 points, i.e. by 3.17 points, though presumably out of 8 not 10 as we've compressed our scale. So 4.5 years = 4.5 x 3.17/8 = 1.78 WALYs lost. So 1.9 to 24 million deaths = 3.4 to 43 WALYs lost.

Presumably the WALYs lost by the financial crisis is also out of 8 not 10, i.e. 0.2/8 per person = 194 million WALYs. Which is 4.5 to 57 times worse than the deaths.

I've just updated the figures (in footnote 7) using Imperial College's latest global forecast of deaths. Previously a global recession like the last one came out as about 1 to 4 times as bad as pandemic deaths (in terms of impact on well-being); now it is 2.8-35 times as bad.

I'm not an expert, but I assume (from a glance at the second paper) this is because the 1%-59% is a cost (opportunity cost), not a value of a life year as such; i.e. in a very poor country you can extend a life by a year for as little as $3, maybe with a vaccine or micronutrient supplement. Actually that seems an order of magnitude too low to me; but nonetheless, it's a great deal!

Indeed, though if working from existing 0-10 life satisfaction scores I don't think it's plausible that those who responded below 5/10 thought they'd be better off dead. (Maybe those responding below say 2/10 would.) Otherwise suicide rates would be far higher.

(But indeed some kind of calibration of death and worse-than-death states is needed more generally. E.g. it concerns me that almost all the bad in the world may be located in extreme pain that is hugely underweighted, and so almost all efforts to improve the world may be missing the point.)

Hi Michael

Thanks for this. (I hope my summary of value of life was mostly right!)

Yes I haven't really given any thought to what the best way of handling the situation would be, or would have been. Clearly complex given that there are sociological/political constraints too (e.g. how would the public react if x% of them die in a new dramatic way - as contrast with, die routinely from seasonal flu or traffic accidents).

It seems to me a global recession could reduce income/employment & hence quality of life without having much effect on life expectancy. For I'm not sure the last recession had much or any identifiable effect on it; growth in life expectancy has slowed since 2008/9, and I asked Paul F about this in a comment below one of his recent articles (which I have indeed been following), but he attributes it to other things. So I wonder if only looking at saving lives is going to miss most of the damage.

I think Paul F is effectively combining quality with quantity of life in his dollar numbers, and converting to whole lives lost as a convenient way to express it, but not completely sure. After all, dollars can be spent on quality or quantity of life.

I look forward to reading your analysis in due course!

Belatedly - thanks. I'm not sure what to make of this. That survey is quite large (30-50,000 people p.a.), so much larger than Eurobarometer, though smaller than ONS (around 150,000). Eurobarometer shows a large rise 1996-2016 (7.19 to 7.74/10), and the later-starting ONS shows a smallish but non-negligible rise 2012-2016 (7.45 to 7.67/10). Possibly again the question wording might have an influence.

But 5.2 to 5.3 is a rise, even if (statistically?) insignificant. It's unfortunate that the paper cites other surveys (in other countries) which confirm its claim of no effect, but doesn't cite these other UK surveys which suggest the opposite.

Since the ONS survey is much the largest, and also kind of confirmed by its findings on happiness (i.e. positive emotions), perhaps the reality is that there has indeed been a substantial rise since 2012, but only a small rise, or perhaps none, before that.

On a separate small point, I think your probability estimate for ESP is too low, for two reasons:

Firstly, it is a taboo topic (like UFOs and the Loch Ness monster), which scientists are therefore far more likely to dismiss from a position of ignorance, or with weakish arguments (e.g. 'it lacks an explanatory mechanism', 'much of the research methodology is flawed', or 'some of the research has been on fraudsters' - hardly disproof). Few skeptics have domain expertise, i.e. of having conducted or investigated research in the area.

Secondly, ESP covers quite a range of rather distinct phenomena. Only one has to be right for ESP to be true. And I'm not sure that all would require completely novel scientific principles (e.g. unknown physical forces); and the fact that our understanding of physics has gaps, and our understanding of consciousness certainly does, may well leave room for some form of ESP to be compatible with current science (not that that is essential).

Great article. I'm very late to the party in reading it & commenting, but I hope not too late to be of use!

I have three further reasons for epistemic immodesty in some circumstances. They all involve experts, or those who follow their advice, being overconfident about the experts' relevant knowledge. (Though I note your comments about debunking experts; none of these arguments show an amateur is better than some other, probably small, set of experts who have taken these considerations into account.)


You mention that expert views aren't relevant in matters of taste, i.e. preference. However, expert views are often based on non-explicit preferences, which some experts may even be unaware of themselves.

To start with a clear situation where preferences are involved: If I'm looking for a house to buy and trying to decide which one to choose, I may well consult experts in the field, such as an estate agent (realtor), a mortgage advisor, and an architect (if it may need building work). They may advise that I can't afford a house more than $x, or it will cost $y to do up, etc. But even with all their expert advice, this won't necessarily settle the matter of which house to buy, because I also have to *like* the house in question, want to live in that area, etc. So my decision involves both expert factual opinion and my personal preference; and I am the sole expert on the latter.

Now to take a less clear situation, currently topical in the UK: Brexit. Despite years of debate about this, which often includes discussion of experts and whether they should be trusted, I don't think I've heard anyone state clearly that it too mixes expert opinion and preference. Most economists say Brexit will harm the economy, and most voters opposed to Brexit assume this simply entails Brexit is a bad thing. But of course the issue is not only about money - various other considerations are involved (e.g. self-determination) - and the trade-off between these is a matter of preference. Some people with unusual preferences may have coherent reasons to oppose Brexit (e.g. I spoke to someone who voted based on the fact that animal welfare is taken more seriously in the UK than most other EU countries, a consideration she regarded as more important than the economy). So this is an example of a 'semi-hidden' preference - one where many people assume expert opinion is a silver bullet - perhaps including the experts themselves - and overlook the element of preference.

A different example is government guidelines on alcohol consumption. In the UK men are advised by experts to drink no more than (I think) 14 units per week. However, this advice is based on a trade-off between health and pleasure: if you really enjoy alcohol you may be happy to exchange a risk of significantly reduced health or longevity for drinking much more than 14 units. This trade-off is a preference, which the experts have made for you. (And AFAIK the trade-off they chose is arbitrary, not even based on research into say average preferences.)

Other topics may include preferences so hidden that even the experts are hardly aware of them. An example in EA would be the use of DALYs and QALYs (disability/quality-adjusted life years) as human welfare metrics in assessing charities & interventions. Some who work with these metrics may overlook, or perhaps be unaware of, their shortcomings. DALYs and QALYs as currently defined assume that no condition is worse than death - which is inconsistent with the existence of suicide and euthanasia. When ordinary people are surveyed, their views on this vary widely - some taking the (perhaps religious) position that nothing is worse than death, and suicide/euthanasia should never be allowed, whereas others have no problem with the idea of suicide/euthanasia to escape prolonged untreatable agony, for example. So the mere use of these units involves tacitly taking a position on this, i.e. a hidden preference. A resulting expert view that X charity or intervention is better than Y is therefore partly objective and partly subjective; the expert themself may overlook this fact, or even (when involving technical philosophical issues) be unaware of it.

Other unstated assumptions are widespread in EA, e.g. that saving lives is a good thing (even though the world may be overpopulated), or that the prevention of merely potential future humans by mass extinction is a bad thing (even though contraception is fine).

In such cases, a non-expert who identifies such a hidden preference that they don't share may well have good reason to disregard the expert opinion.


Relatedly, there is the issue of core assumptions that are largely unquestioned within a scientific field. A classic example is induction: physics assumes that just because in the past things seem to have behaved in a regular fashion, they will continue to do so. This is the basis of the belief in physical laws (and other laws of nature). Philosophers have long questioned this assumption; there really may be no reason to assume the sun will rise tomorrow, or that the speed of light was the same yesterday or a million years ago; which undermines all kinds of experiments and models. I expect many physicists are only dimly aware of this, know little of the arguments involved, and perhaps regard it as a quasi-theological debate not worth serious attention.

As with DALYs and QALYs, core assumptions like induction are often shaky, and the shakiness is often only taken seriously (or even known about) by those outside the field, e.g. philosophers. Indeed, articles of faith are often left unquestioned by true believers, lest they turn out to be an Achilles heel, and (mixing more metaphors) the whole edifice is built on sand. To question foundational beliefs may be heresy.

So an amateur outsider may well be more aware of such problems than an expert in the field; and may therefore be justified in using them to dismiss expert opinion, or at least, to take it with a big pinch of salt.


Many experts are only expert in an extremely narrow field, yet may be assumed to have a broader range of expertise (and some experts may also believe this themselves).

Apologies, but the clearest example I can think of is myself! At one time I was one of just a handful of world experts in an extremely narrow field - the music notation software industry. (As I owned a company in this field.) My knowledge was extremely in-depth - I had spent years coding this kind of software, knew endless obscure feature requirements, knew all about the market, wrote manuals and brochures, etc. Yet in other respects I knew less than many amateurs. I had never used (and hardly even seen) any music notation software other than my own company's. I knew even less about other types of music software (e.g. sequencers), used by millions of people, often my own customers. So I was a world expert in a very narrow field, yet an ignoramus both in aspects of my own field, and in very close fields.

The same is presumably true elsewhere. Amateurs may know as much as a world expert who is only slightly outside their very narrow field, or even on topics within their specialism. And at least occasionally, experts are unaware of their ignorance on these things. That is, they may make the same false assumptions as others do about the breadth & depth of their expertise.

(An example: the book The Oxford Companion to the Mind is an encyclopedia edited by the eminent psychologist Richard Gregory. Some of the entries in the original edition are by Gregory himself, despite dealing with philosophy of mind & metaphysics, topics evidently outside his expertise. They are amateurish, making confusions that would embarrass a philosophy undergraduate. Even the blurb on the cover jacket casually conflated 'brain' and 'mind' in ways only an ignoramus would do. When I was a philosophy student I was so astonished by this I almost wrote a letter to Gregory suggesting he get someone with domain expertise to rewrite his entries.)

Actually there has been one change in method - in 1998 it was made illegal to sell large quantities of paracetomol, to make casual suicide harder. The suicide rate has been falling since but there was no sudden drop, so I'm not sure we can attribute much effect to that.

Thanks for this.

The ONS suicide data is from 1981, showing a decline by about a third by 2007 - pretty big, and I'm not aware that any popular suicide method became less available in that time.

(Unlike e.g. coal gas used in ovens, once a popular suicide method but it was phased out in the 1960s and 1970s leading to a suicide reduction - I don't think coal gas was available thereafter as the last plant closed in the late 1970s. And guns have never been generally available in the UK.)

The methods used have apparently changed popularity in recent years; hanging/suffocation/strangulation and poisoning are the most popular:

But I'm not sure why they have changed other than 'fashion'. It could be the case that some of these methods are significantly more effective than others which could affect the statistics, but I doubt by this much.

Also I'm not aware that suicide has changed in acceptability in the UK in recent decades. It was never considered acceptable (unlike say in Japan).

So I'm still inclined to regard suicide as a better proxy of extreme mental health problems than anything else. (That said, I'm not an expert at all in this area.)

Thanks, very useful. The World Happiness Report data (from Gallup World Poll; I'd seen the figures before but couldn't find more info) does show a rise of about 0.25/10 over the period - about one-third of the rise in the other ONS and Eurobarometer results (when Eurobarometer converted to a score out of 10).

I suspect the difference is in the wording of the question, which defines 0 as 'the worst possible life for you' and 10 as 'the best possible life for you' and asks where they are now. (It doesn't mention the word 'satisfaction'). Whereas the ONS question is 'Overall, how satisfied are you with your life nowadays?' where 0 = not at all satisfied and 10 = completely satisfied (Eurobarometer has similar wording AFAIK). They're rather different, and personally I find the 'life for you' wording (which I've come across before) a bit confusing, as does 10 mean 'doing as well as I could given my abilities & circumstances' or 'having the best life I can imagine (with no restriction)'?

[ADDED] To put it another way, the Gallup question seems to be asking people to compare with some unclear external scale of what's possible for their life (in the real world? in a fantasy world in which they could be a rock star or Bill Gates?), rather than how satisfied they feel about their life (a more internal scale of feelings). If they're comparing where they actually are with what might be possible in a fantasy world, it's not so surprising it doesn't go up much, because reality rarely approaches fantasy.

Without deciding which survey has a 'better wording', if any of them shows a substantial effect then it suggests something is going on in whatever that question is measuring.

There is a lot of happiness data available, including from the ONS, but there is a tendency now to prefer life satisfaction because it's more stable (happiness varies with the weather and day of the week) and more all-encompassing. So I didn't look into it. Though the ONS happiness data show the same trend over time as satisfaction.

(On a lesser point, I don't know how large the Gallup poll is but I imagine, like Eurobarometer, it's a few thousand people per country. The ONS is over 150,000 so very reliable. That said, aggregating multiple years removes the sample size problem.)

Thanks. It's a very cool site. I couldn't figure out how to find the source, but never mind. The figures for England (the vast majority of the UK population) do indeed show a slight decline so at least that's consistent with my hunch, though not explaining much of the misery fall (and it shows anxiety as completely flat). Possibly there was a bigger mental health improvement in the 1970s/1980s. More likely these figures measure presenting or treatment rather than pure prevalence, so hard to conclude much.

On the aging thing I've just done a rough estimate. The median age increased about 3 years between 1999 and 2019, and as it's around 40 which is before the mid-life crisis (life satisfaction being U-shaped as you age, the lowpoint around 50), an age increase of 3 years would if anything lower happiness. (Of course it would be a mix of some going down and others up depending on their ages, but the overall effect would presumably be down. Incidentally the bottom of the U-shape hasn't noticeably got older as the population aged over this period.)

But the effect is small anyway - the median, getting 3 years older, would lose about 0.07/10 points life satisfaction (when expressed as a score out of 10), which is only about 10% of the 1999-2019 change, as well as in the wrong direction.

More consistent with the blue line falling due in part to better treatments. (If they’re significantly better; may well be more widely prescribed anyway.)

Do you know how this data was gathered? The prevalence of mental health problems is presumably hard to determine (see my footnote 7). I’m inclined to believe the falling suicide stats as a proxy, as they’re objective.

The aging did occur to me, but without doing the numbers I doubt it would have an effect that fast on happiness, and certainly not that fast on misery.

Re immigration, research shows immigrants mostly take on the happiness of the country they move to, partly retaining their previous happiness. And as most recent immigration has been from less happy countries (eg Eastern Europe), I’d expect the effect to be a small fall in happiness not a rise. Though again without doing the figures I doubt it would be big enough to affect the general shape of the graphs.

Good article. Various things you mention are examples of bad metrics. Another common kind is metrics involving thresholds, e.g. the number of people below a poverty line. Since they treat all people below, or above, the line as equal to each other, when this is far from the case. (Living on $1/day is far harder than $1.90/day.) This often results in organisations wasting vast amounts of money/effort moving people from just below the line to just above, with little actual improvement, and perhaps ignoring others who could have been helped much more even if they couldn't be moved across the line.

Very good article. Re marriage, and also the Easterlin Paradox:

Re fig 1, marriage, more recent research shows the apparent reversion of satisfaction to singlehood level (or less) a few years after marriage actually just results from not controlling for age properly. Specifically, from the U-shaped happiness curve during the life course - people tend to marry before middle age, so get less happy as they approach middle age, not because of the marriage. (I think this may be mentioned in the recent Origins of Happiness book.)

Re fig 3 for UK, actually if you look at a longer time-series e.g. Eurobarometer (since 1973), UK life satisfaction has gone up significantly - from around 7.1 in the 1970s to 7.7/10 in 2018 (after transforming to 0-10 scale); and rather more since the only older survey I could find, 5.7/10 in 1948.

Also re China, you say elsewhere 'it’s SWB seems to have gone down been 1990 and 2015, even though per capita GDP increased by 5 times'. I haven't read the report you refer to, but I the World Value Survey on happiness (as opposed to life satisfaction) shows the proportion of Chinese who are happy rising from 67% in 1993 to 85% in 2014. (You can check it on the second chart here: )

So maybe the Easterlin paradox does not exist, or at least, is limited.

A very interesting post (as was the previous one). On this point:

It seems most likely to me that marginal impact would have an S-shape... An additional person would probably do much more good for a small- or medium-sized march.

I expect in fact it's a large march where they make the most difference.

I model my guess at the likely curve shape and resulting benefit in a recent post, Rationality of demonstrating & voting.

Very interesting - by pure chance I spent this morning thinking about this topic (from a position of relative ignorance). I look forward to the rest of the series!

Not sure this follows. If we're capable of intelligently working out what's good for us, that makes us able to work out how to avoid the pain. But it doesn't seem a good reason for evolution to reduce the pain, as that would reduce the incentive for us to try to avoid it.

I agree. I'm extremely wary of suggestions that you can compare the strength of children & adults' emotions/pain from their behaviour (or perhaps any other way). So it seems to me the only reasonable assumption is that they are the same for all humans who are fully conscious. (I.e. possibly lower for young babies, some mentally disabled; though the precautionary principle suggests we shouldn't assume this.)
