Area 1: Foundational research into the measurement of wellbeing

Fundamental to any effort to increase wellbeing is a theoretically sound and empirically robust account of what wellbeing is and how it should be measured. 

1.1 The nature of wellbeing

In order to measure wellbeing, we must first establish what it is.

Following Parfit (1984), philosophers standardly differentiate three accounts of wellbeing, that is what makes someone’s life go well for them: (1) hedonism, wellbeing consists in happiness, i.e. overall positive conscious states; (2) desire-fulfilment theories, wellbeing consists in getting what you want; (3) objective list theories, wellbeing may consist in happiness and/or satisfied desires in addition to other ‘objective’ goods, e.g. wisdom, love, friendship, and autonomy.

As one might expect, the theoretical pros and cons of these three accounts have been heavily discussed in academic philosophy (Crisp, 2008); see here for our short, non-technical summary of this debate. Given this, we do not consider academic philosophy work into wellbeing to be, in general, high-impact. Is this presumptuous? Are there new perspectives we are overlooking? 

Curiously, however, social scientists’ efforts to gauge subjective wellbeing measures have proceeded somewhat in parallel to these philosophical discussions. Subjective wellbeing is often taken to have three measurable components: an experiential component (sometimes ‘affective’, ‘happiness’, ‘hedonic’), an evaluative component (a judgement of how life, or some part of it, is going; sometimes ‘cognitive’), and a ‘eudaimonic’ component (an assessment of meaning or purpose in life) (OECD 2013).

While experiential measures seem to fit well within hedonism, it is less obvious how evaluative or eudaimonic measures connect to the canonical philosophical accounts of wellbeing. We are, or have been, more optimistic about work bringing subjective wellbeing measures into theoretical alignment with coherent philosophical accounts of wellbeing.

The most commonly used subjective wellbeing question is life satisfaction, an evaluative measure. This is typically found by asking, “Overall, how satisfied are you with your life, nowadays” (0 – 10). This, combined with doubts about life satisfaction’s relationship to extant theories of wellbeing, motivated our earlier work: Plant (2020a) investigated the nature and plausibility of life satisfaction theories of wellbeing.

Plant argued that life satisfaction theories are best understood as a type of desire-fulfilment theory in disguise and then pressed two serious objections to such a view. One objection is that the view implies (counter-intuitively) that most animals cannot have wellbeing as they cannot make an overall assessment of their lives. Given the objections, Plant concluded that life satisfaction theories are not plausible candidates for a theory of wellbeing.

On the basis of this analysis, we are not currently prioritising additional research on the nature of and plausibility of life satisfaction theories, although we expect this debate will continue. Can life satisfaction theories be rescued from such criticisms? Is this the right way to understand them?

Further work could examine the nature of the relationship between objective list theories of wellbeing, eudaimonic measures of subjective wellbeing, and the concept of a meaningful life, as well as their importance.¹ We note accounts of meaning may suffer the same challenge noted for life satisfaction theories, namely that many animals seem incapable of evaluating their lives as meaningful. For instance, the connection between Aristotle’s original conception of eudaimonic, and so-called ‘eudaimonic’ measures of wellbeing, is open to debate; see Vitterso (2016) for a recent collection of some issues in this area. 

For clarity, as the name of this organisation, as well as the introduction indicates, we are most sympathetic to the view that happiness is what ultimately matters. Given that, and that there is not very much research into meaning being undertaken, further research into meaning does not seem very urgent.

It is worth emphasising, however, that our research is not just of interest to card-carrying hedonists. We intend to present, where possible, what the research indicates best improves each of happiness, life satisfaction, and meaning; on any plausible view of wellbeing, these are either contributors or constitutes of wellbeing, and so crucial information for decision-makers.

1.2 The measurement of wellbeing

1.2.1 Can subjective states, for instance happiness, be measured in theory?

A long-standing worry is that it is not possible, even in theory, to measure subjective states such as happiness or life satisfaction.

The recent view in philosophy of science seems to be that subjective wellbeing is, in principle, measurable in just the same way that other latent (i.e. unobservable) constructs, such as intelligence and personality, are (Anger, 2011, 2013; Alexandrova and Haybron, 2016). This consensus relies on the construct validation theory of measurement. Thus, claiming that subjective wellbeing is not measurable because construct validation is false would lead to the arguably implausible conclusion that huge swathes of social science, which also rely on construct validation, are mistaken.

Given this issue is foundational, we thought it merited double-checking ourselves (HLI, 2020a). Our update was that the construct validation approach seems unavoidable and unobjectionable.

To explain, in brief, the idea behind construct validation for latent phenomena is this. Although the constructs (particular phenomena or attributes) are latent, you assume there are measures, ways to elicit the observable indicators of the construct. To check if the measures are valid—that is, successfully measure the underlying constructs—social scientists engage in a process of construct validation, where the measure of the construct is tested to ensure that it behaves in the way we think it should, given the researchers’ existing understanding of the topic.

As a simple example, if you expect more intelligent people to earn more on average, and that IQ scores measure intelligence, then higher IQ scores should be associated with higher earnings. Whether a construct is valid is ultimately determined by a judgement, as opposed to a test, when looking at the full sweep of evidence. It wasn’t clear to us what other method one would use to reasonably assess if a measure was any good. 

Part of our internal confusion on the topic stemmed from the fact that social scientists talk about different types of validity (e.g. ‘face’, ‘content’, ‘discriminant’, ‘convergent’, etc.) and it wasn’t clear how they fitted together. The report clarified this by tracing the intellectual history of such terms (HLI, 2020a). Roughly, the concept of validity has evolved over time, but the overarchingly important sense of validity is construct validity (does a measure behave as expected?) and the other types of validity just test aspects of that.

Is the conclusion that construction validation is unavoidable and unobjectionable correct, or too bold? Is there anything more to be said on this topic?

1.2.2 Given subjective wellbeing can be measured in theory, how good are our current measures? How can we convert within and between subjective wellbeing and other measures?

On the construct validation framework, a measure is deemed valid if it succeeds in capturing the underlying construct it is supposed to be capturing. One might accept that subjective wellbeing can be measured in theory but deny that the current measures are, in fact, valid.

Social scientists often tend to claim the balance of evidence shows measures of subjective wellbeing are valid because they behave in the way we expect them to. For example, we expect richer people to be more satisfied, at least up to a point, and that is what the data shows, indicating that the purported measures of life satisfaction do measure life satisfaction; see OECD (2013) for an excellent overview.

Broadly, we are satisfied that the various purported measures for each component do capture that component, e.g. that life satisfaction and the Cantril Ladder, two evaluative measures, both convey information about how individuals judge their own lives (OECD 2013).

We are also satisfied that evaluative measures of wellbeing are reasonable, but non-ideal, proxies for experienced measures of wellbeing, i.e. those of happiness. The two share a moderate correlation, the same things seem to increase happiness and life satisfaction, but some things are more important for one than the other, e.g. income matters more for life satisfaction than happiness (Boarini et al., 2012). Hence, we can generally assume life satisfaction and happiness scores will indicate the same things are good(/bad) but may differ over the overall priority ranking. This needs to be borne in mind.

There are, however, open questions.

First, what would be the theoretically ideal measure for each account of wellbeing, and which of the current options is closest in each case? Usually, measures are described as valid or not. But presumably validity admits of degree; measures can be more or less accurate. To illustrate, the Positive and Negative Affect Scale (PANAS), the Day Reconstruction Method (DRM), and the Experience Sampling Method (ESM) are all regarded as validated measures of happiness. Should we say they are all equally good as measures of happiness as each other? In which case, what would we do if they disagreed?

Second, and relatedly, how different are the results for various measures, both among measures of a given component and across the components? And how can we convert between them and other proxies for wellbeing, e.g health measures? This matters because subjective wellbeing is often measured in different ways and, if we want to know what the result would be in terms of a particular measure, we have to know how to convert or adjust between the measures. 

Given the prominence of life satisfaction data (a measure of how individuals judge their lives) and our primary interest in happiness (how good/bad individuals feel during their lives) the priority question is: How best can we convert from the former into the latter?

We are aware of some efforts to convert not just between measures of subjective wellbeing, but between subjective wellbeing and other metrics, such as various health scores, including Quality- and Disability-Adjusted Life Years (QALYs and DALYs) (Layard, 2016). We are not aware of anything reasonably comprehensive.

Third, which measure of each component should be used in practice? Plausibly, the most accurate measures of wellbeing, and thus those we would ideally use given unlimited resources, are not ideal in reality, given limited resources. This might be because more accurate data-collection methods are more effortful for subjects, and so less practical to use. For instance, the Experience Sampling Method, which requires subjects to say how they feel many times a day, requires more work than using the Positive And Negative Affect Scale, which asks them about a range of recent emotions and can be done in one go. To be able to make recommendations about which measures are mostly practically useful, information on the trade-offs and adjustments is needed.

1.2.3 To what extent are happiness (and other subjective) scores comparable?

​It is very common for people to give numerical ratings of their subjective experiences. For instance, people often score their happiness, life satisfaction, job satisfaction, health, pain, the movies they watch, and so on, on a 0-10 scale.

A long-standing worry about these self-reports is whether the numbers are comparable and so mean the same thing to different people at different times. For example, if two people say they are 5/10 happy, can we assume they are as happy as each other? More technically, the main (but not only) question is whether subjective scales are cardinally comparable: does a one-point change, on a given scale, represent the same size change for different people and at different times?

Opinions are split, largely on disciplinary lines: psychologists are sympathetic to the cardinality assumption, economists are suspicious of it (Ferrer-i-Carbonell and Frijters, 2004). Only a handful of papers have investigated various aspects of this issue, despite its fundamental importance—for discussion of this, see Kristoffersen (2011), Stone and Kruger (2018). However, determining the truth of the matter is difficult because it isn’t clear exactly which assumptions are required, in theory, for cardinal comparability and whether, in reality, they hold. 

In recent work, we have investigated this topic. Plant (2020b) attempts what we believe is the first comprehensive overview of the topic. Plant notes there are four individually necessary and sufficient conditions for cardinal comparability of subjective data: (1) phenomenal cardinality (subjective states like happiness are perceived in units), (2) linearity (individuals perceive the units of the scale convey equal changes), (3) intertemporality (each individual uses the same end-points of the scale over time), (4), interpersonality (different individuals use the same end-points of the scale at a time). (2) – (4) are about how people interpret subjective scales.

Plant also offers a novel hypothesis for why people might be trying to interpret subjective scales in a cardinally comparable way. Following philosopher of language, Paul Grice (1989), language use is a cooperative endeavour where we try to make ourselves understood. As the meaning of subjective scales is vague and individuals want to be understood, scale interpretation can be understood as what is known in economic game theory as a search for a ‘focal point’ (or ‘Schelling point’), a default solution chosen in the absence of communication (Schelling, 1960). Plant surveys the current empirical literature relevant to each condition and tentatively concludes each condition is met and hence subjective data should be interpreted as cardinally comparable, at least until and unless other evidence suggests otherwise. Plant also suggested some further tests.

Since the writing of Plant (2020b), research has indicated there may be individual differences in scale use (Benjamin et al., MS) and that individuals alter their scale use over time (Kaiser, 2020), although it is unclear how substantial the deviations from cardinality would be. 

At present, given the scant evidence base, we strongly encourage further empirical tests of the various conditions. These could shed new light on whether the conditions are met, or, if they aren’t, the extent to which they aren’t, and how to correct for it. For instance, if we knew that, on average, people living in Germany used a scale 10% ‘taller’ than people living in France we could correct for that to make their answers comparable. While we don’t plan to do this work internally, we would be excited to explore (further) collaborations with empirical researchers working on this topic.

1.3 Developing the ‘WELLBY’ approach: issues with putting changes to quality and quantity of life into a single metric

It’s common to measure impact using objective measures, such as health or wealth. But what ultimately matters, we believe, is the effect on how people think or feel, that is, on their subjective wellbeing. On the basis of our understanding of the topics above, we conclude that measures of subjective wellbeing are valid and comparable. As such, subjective wellbeing scores offer an invaluable tool: a common currency in which to measure the impact different interventions have on quality of life, for instance those which alleviate poverty, enhance education, or improve mental health. 

By combining information about how much wellbeing has changed with objective information about duration, we can quantify the value of outcomes in terms of a common currency, Wellbeing-Adjusted Life-Years, or ‘WELLBYs.’ We might specify an outcome which raised life satisfaction by 1-point on a 0-10 scale for one year is worth ‘1 WELLBY’. Hence, another outcome which raised life satisfaction by 0.5 points for 2 years would also be worth 1 WELLBY, and so on.

We consider translating the value of different actions into WELLBYs, so we can then work out the most cost-effective ways to benefit individuals, to be at the core of what we do. Our projects mostly either improve this method or apply it.

To be clear, the WELLBY approach is not theoretically novel. Victorian ethicists and economists such as Jeremy Bentham and Frances Edgeworth would immediately recognise the idea behind it (Bentham, 1789; Edgeworth, 1881). Putting the theory into practice is, however, new , and attempts to do so have only begun in the last few years (Bronsteen,  Buccafusco, and Masur, 2012; Frijters and Krekel, 2019; Frijters et al. 2019; Layard et al., 2020; Plant, 2019),

Clearly, this is a major empirical task, an issue discussed further in area 2, particularly 2.3. In many cases, we expect to generate the first estimates of the impact of different interventions using subjective wellbeing.

However, it is not only an empirical project. If we want to produce a single, all things considered, cost-effectiveness number in terms of WELLBYs we have to make some philosophical choices, namely:² A further issue, and one we don’t discuss, pertains to theories of value aggregation. For instance, do we opt for a utilitarian theory of aggregation, where the best outcome is the one with the highest unweighted sum of wellbeing, or (say) a prioritarian function, which gives more weight to increasing the wellbeing of the worse off? See Holtug (2015) for a good summary of the options and issues.

The utilitarian approach is the standard one used by subjective wellbeing research, i.e. all the data are summed together when assessing overall changes. We don’t discuss this issue because (1) we are sympathetic to the utilitarian theory of aggregation anyway and (2) attempting anything else would be extremely impractical. It would involve getting access to, then reanalysing, any study of interest ourselves, rather than using the crude average already given. 

• What is the preferred account and measure of wellbeing? For instance, does happiness or life satisfaction matter more?
• How do we compare improving lives to extending lives? In other words, what is the right account of the badness of death?
• How do we compare improving or extending lives with creating or averting new lives? In other words, what is the right account of population ethics?³ Some readers may wonder how all this fits together. Population ethics concerns the issues that arise when the number of individuals who ever live, their identities, and their levels of life-time wellbeing vary. The standard unit of aggregation in population ethics is the lifetime wellbeing of individuals. Discussions in population ethics thus usually leave open how the lifetime wellbeing level of individuals is determined. Different accounts of the badness of death offer differ answers over exactly how individual’s lifetime wellbeing levels are to be determined.
• Where on subjective wellbeing scales is the ‘neutral point’ equivalent to non-existence? This is needed to compare improving lives to either extending lives or altering the number of lives.

For an informal discussion of how views of population ethics and the badness of death may alter prioritisation decisions, see Plant (2016), and Cotra (2016) for a reply, as well as HLI (2020b).

These issues—with the exception of choosing between theories and measures of wellbeing, which we have already discussed (1.1, 1.2)—are elaborated in the next three subsections.

1.3.1 Comparing existence to non-existence: where, on subjective wellbeing scales, is the ‘neutral point’? 

The most common measure of subjective wellbeing is life satisfaction, which is usually measured on a 0-10 scale. Which point on the 0-10 scale is equivalent in value for someone as non-existence? What is the correct means for determining this? As noted, this is relevant for comparing improving lives to extending or altering the number of lives. The following explanation is drawn from HLI (2020b).

One might assume that the middle point on the scale—5/10—is the neutral point. Subjective wellbeing researchers sometimes treat the mid-point of subjective wellbeing scales as where someone is neither satisfied nor dissatisfied, or neither happy nor unhappy, e.g. Diener et al. (2018). This has the controversial implication many of those in developing countries have lives ‘not worth continuing’—average life satisfaction in (e.g.) Kenya is 4.4.

However, a neutral point of zero is difficult to reconcile with widely-held intuitions. It implies that a life filled with agony is always worth continuing (at least, considering just the person whose life it is) even if the individual themselves would prefer to die.

Getting the neutral point wrong means resources will be spent inappropriately, either putting too much, or too little, weight on averting deaths vs improving lives, with obvious implications for private philanthropy and public policy.

There is almost no work discussing how, in principle, to determine where the neutral point should be (HLI, 2020b). One implicit assumption is that it is wherever individuals say it is. It’s not obvious this is the right approach and it generates prima facie oddities: if two people assess their quality of life as the same, but only one of them can be saved, the decision turns on a seemingly arbitrary decision about where they perceive the neutral point to be for themself.

We think conducting work here is an internal priority, at least to sketch some possible approaches, evaluate them, and set out a way forward. This is not least because our initial work into the cost-effectiveness of life-extending vs life-improving interventions is highly sensitive to the choice of a neutral point (HLI, 2020b).

1.3.2 Comparing the value of improving lives to extending lives: different views on the badness of death

Comparing improving to extending lives requires taking a stand between different accounts of the badness of death. See Gamlung and Solberg (2019) for a recent collection of essays.

Perhaps the standard view of the badness of death is deprivationism, where the badness of someone’s death, for them, is the amount of wellbeing they would have had, if they had lived. This is a product of the number of years they would have lived multiplied by their net wellbeing (their level of wellbeing above the neutral point).

Deprivationism is not the only view of the badness of death. Another is the Time–Relative Interest Account (TRIA), where the badness of death is a function of the future wellbeing the person would have had combined with also their psychological connection to their future self at later stages. TRIA captures the common intuition that it’s better to save 20-year-olds than 2-year-olds, even though the latter would live longer, because the 2-year-old has a much weaker interest in continuing to live.

A third view is Epicureanism, where someone’s death is not bad for them. This is perhaps motivated by the sense that existence and non-existence cannot properly be compared in value for someone.

To be clear, these are views about the badness of death for someone. On each view we can still count the badness of dying for someone, e.g. if painful, and the effect of a person’s death on others.

Comparing the value of some life-improving vs life-extending interventions will depend quite substantially on which view is taken. Given there is already an existing philosophical literature, we do not plan to prioritise original academic work evaluating these views; however, we do plan to summarise, in accessible language, the existing arguments for and against the various options to inform decision-makers facing these choices.

One open question which may be of practical importance is how exactly to fill in the details of TRIA—there are multiple ways to make precise the view such that it captures the intuition that saving adults is more valuable than saving young children (HLI, 2020b).

1.3.3 Comparing the value of improving lives to creating lives: population ethics

Lots of questions in ethics concern fixed populations, that is, where the number of people we affect, and who they are, is fixed. Sometimes, however, we encounter variable-population cases, where our actions may determine not just who gets born, but how many people get born, and as well as how their lives go. Variable population ethics, hereafter, just ‘population ethics’, concerns the special issues that arise when the number of individuals who ever live, their identities, and their levels of life-time wellbeing vary (Greaves, 2017).

If we want to compare the value of improving the lives of current people to that of adding (/averting) new lives, we must take (implicitly or explicitly) a stand on population ethics. 

The (mathematically) simplest view of population ethics is totalism, where the value of an outcome is the sum of lifetime wellbeing for everyone who ever lives. On totalism, adding happy new lives is good. In contrast to totalism are person-affecting views, which hold, in slogan form “morality is about making people happy, not about making happy people.” There are a number of ways to make this precise, but the gist is that adding new (happy) lives is neutral in value.⁴ More technically, that it has no value, i.e. its value is undefined, rather than that it has a value, and that value is zero. There are many other views, but these need not detain us here.

Clearly, how one thinks about this choice will affect the value of interventions that change the number of people who are created, such as family planning interventions that reduce fertility rates. Non-obviously, this may affect the value of life-extending interventions. If parents desire a specific number of adult children, reducing child mortality may correspondingly reduce female fertility. 

As for the badness of death, this area also has a substantial academic literature already; we expect to present the views, their implications, and the existing arguments, but not prioritise novel investigation ourselves.

Area 2: Applied research to identify and evaluate the most cost-effective ways to increase wellbeing

Fulfilling our mission requires determining which actions, for given actors, are the most cost-effective means of increasing wellbeing. To identify potential priorities, it helps to have a broad understanding of what sort of things impact wellbeing, and what the barriers are to realising those improvements. From here, it is then possible to narrow down to specific options, then evaluate these for their cost-effectiveness. The following research topics in area 2 progress from quite broad ‘background’ issues to more specific ones about the cost-effectiveness of particular interventions. 

To restate our comment made in the introduction: our current focus, and where the majority of our effort will go, is area 2.3: using subjective wellbeing scores to compare the cost-effectiveness of highly-regarded health and development interventions used in low-income countries.

2.1 Understanding the causes and correlates of subjective wellbeing

There is now a profusion of research into the causes and correlates of subjective wellbeing. What are the latest summaries  about what sort of things impact wellbeing, and by how much (Dolan et al. 2008)? Are there particular sets of evidence that are more important to be aware of than others? 

Decisions in health prioritisation seem to be quite influenced by the Global Burden of Disease report, which identifies how many Disability-Adjusted Life-Years (DALYs) are lost to various diseases. Would it be helpful to construct a similar ‘Sources of Lost Worldwide Happiness’ or ‘Global Burdens of Suffering’ report, which identified the lost wellbeing from various sources (GBD, 2018)?

It seems possible to identify fairly general mechanisms about how subjective wellbeing functions, such as hedonic adaptation, getting used to life changes (Luhmann et al. 2012); social comparison, how we assess our lives and experiences in comparison to relevant others (Alderson and Katz-Gerro, 2016); biases in affective forecasting, ways in which we mispredict how the future will feel to ourselves and others (Wilson and Gilbert, 2005). What is the latest on these? To what extent might they inform thinking about where the priorities might lie?

Can evolutionary theory offer novel insights by providing an account of what the evolutionary  purpose of valenced psychological states (i.e. happiness) is (Graham and Oswald, 2010; Perez-Truglia, 2012; Rayo and Becker, 2007)? Equally, what, if any, decision-relevant information can be gained from understanding of the neuroanatomy of valence states (Kringelbach and Berridge, 2010)?

One long-running topic of interest is the relationship between happiness and income. A common line of thought is that there is no need for governments to focus specifically on wellbeing: we can just grow the economy and wellbeing will take care of itself. However, this view is in tension with the so-called ‘Easterlin Paradox’ (Easterlin 1974; 2016; Kaiser and Vendrik, 2016; Stevenson and Wolfers, 2008). The paradox is the finding that, at least in rich countries, increasing wealth over time does not seem to increase aggregate subjective wellbeing, even though richer people are happier than poorer people.

Is the paradox true and, if so, what does it imply for national policies? How mysterious is it that wellbeing would not increase in aggregate despite the improvements in many non-pecuniary aspects of life in these countries, such as greater health provision?

We do not plan to conduct original academic research or produce systematic reviews in this area; such work less directly advances our understanding of how best to increase wellbeing. However, we are likely to produce short reviews both to deepen our own understanding and communicate these issues to our audience.

2.2 Cause area analysis

With a broad appreciation of what affects human wellbeing, the further level of analysis is focusing on more specific problems with the aim of identifying the best ways to make progress on each.

2.2.1 Cause prioritisation methodology

Given there are lots of problems out there, it would be helpful if there were a method that allowed us to prioritise between them without, somehow, getting into the ‘nitty gritty’ of quantifying the cost-effectiveness of interventions.

A popular claim among members of the effective altruism community is that different problems should be prioritised according to an assessment of their scale, neglectedness, and tractability, which can be used as heuristics (MacAskill, 2015; 2018); further, cause prioritisation and intervention evaluation should be understood as genuinely separate steps that can be done in turn (Dickens, 2016; Wiblin, 2016). Cotton-Barratt (2016) proposes formalising scale, neglectedness, and tractability as three factors that combine to determine the marginal cost-effectiveness of further resources to a problem.

However, if we understand ‘causes’ as problems and ‘interventions’ as solutions, it becomes unclear how we can evaluate the cost-effectiveness of problems somehow ‘in the abstract’, in a way that is prior to, and distinct from, assessing particular solutions to those problems (Plant 2019). In this case, the purported distinctiveness of ‘cause prioritisation’ from ‘intervention evaluation’ breaks down; we no longer seem to have a method of prioritising between causes that avoids us getting into the ‘nitty gritty’ of assessing interventions to them. One potential way to proceed is by engaging in cause mapping, where, in short, we try to set the actions one could take to solve a problem, the potential obstacles for each action, and a further assessment of how each obstacle might be addressed; the result is a semi-exhaustive set of options for further investigation (Plant 2019).

In some ways, this is a very disappointing, but perhaps unsurprising, result: we do not have a particular method for quickly evaluating various problems. Rather, we must simply make intuitive judgments about how good the solutions are, then evaluate some of them in greater depth. We do not plan to investigate cause prioritisation methodology further as it is unclear how progress could be made.

Is this analysis mistaken? Is it possible, after all, to evaluate ‘causes’ independently of evaluating specific interventions? What short-cuts, if any, are available for this?

2.2.2 Problem area investigations

As a way of identifying promising solutions to a given problem, it seems useful to gain an overview of that problem and understand it from various angles. Questions whose answers may be relevant include: How many people does the problem affect and by how much? What is being done about this problem at the moment? What could be done? What is getting in the way of useful solutions being used?

Various examples of ‘cause area’ or ‘problem area’ problems from the effective altruism community are given below. Various organisations, such as 80,000 Hours, Founders Pledge, and Open Philanthropy, produce a range of these for the benefit of donors.

As noted, members of the effective altruism community often claim that focusing on poverty and physical health in low-income countries will be the most effective way to help people alive today (MacAskill, 2015). This seems plausible, but is not certainly the case. We plan to evaluate a range of causes, using the lens of subjective wellbeing, to determine the most impactful ways to do good. 

We have recently produced a problem area report on pain (HLI, 2020c). We are currently working on a similar problem area report into mental health.

How useful is it to conduct this sort of overview research? If it is useful, what would be appropriate directions for further work?

2.3 Using subjective wellbeing to compare the cost-effectiveness of highly-regarded health and development interventions used in low-income countries

The question of ultimate interest, and that preceding topics inform, is: what are the most cost-effective ways to increase wellbeing? Evaluating this requires examining particular options, looking at the evidence, and making estimates. Efforts to assess the cost-effectiveness of outcomes in terms of subjective wellbeing are in their infancy, having only begun in the last 10 years; in many cases, we expect our estimates to be the first (Bronsteen,  Buccafusco, and Masur, 2012; Frijters and Krekel, 2019; Frijters et al. 2019; Layard et al., 2020; Plant, 2019).

Our immediate priority is assessing the cost-effectiveness of several health and development interventions in low-income countries. We focus on these because the effective altruism-aligned charity evaluator GiveWell, has suggested that, amongst all the options available to charitable donors, the most impactful per dollar are certain health and development interventions; their specific recommendations include life-saving anti-malarial bednets and giving large sums of cash to very poor people. These are ‘atomic’ or ‘micro’ interventions in the sense they impact one person at a time, as opposed to ‘systemic’ or ‘macro’ interventions, such as a public policy change, which work across an entire society. 

While these are certainly plausible candidates for the best interventions, these have not yet had their impact assessed in terms of subjective wellbeing; nor, either, has it been set out how their cost-effectiveness may be sensitive to different moral assumptions (as noted in 1.3 above). Therefore, the natural next step is to estimate the cost-effectiveness of these interventions in subjective wellbeing using available evidence, and presenting the results given different moral views. 

The further step is to analyse other ‘atomic’ interventions which seem plausibly highly-effective but have not yet been considered top priorities by those in the effective altruism community (GiveWell, 2021). On this list are psychotherapy for depression and cataract surgery for blindness. Focusing on other atomic interventions allows an ‘apples-to-apples’ comparison: it should be unambiguously clear if new priorities emerge. If they do and our research is used (and, further, we are correct!) this should result in tens or hundreds of millions of dollars a year going to more effective interventions. 

In broad terms, our method is as follows. We select interventions that seem intuitively promising to us or others. We survey the literature to find relevant studies that measure impact in terms of subjective wellbeing (or something we can convert into subjective wellbeing). We then create models of the average total effect over time and the cost, using a Monte Carlo simulation (rather than point estimates) to account for uncertainty. We build several such models to account for different moral assumptions, as noted in 1.3. 

To create these cost-effectiveness analyses requires putting several jigsaw pieces together. So far, we have already conducted, in collaboration with two external academics, a meta-analytic review of the impact of cash transfers for subjective wellbeing (McGuire, Bach-Mortensen and Kaiser, 2020). 

We have also developed a method for comparing improving lives to extending lives using units of subjective wellbeing, including how this is sensitive to two different views of the badness of death (HLI, 2020b). Further research will evaluate other interventions, expand the sensitivity of our analysis to incorporate different moral views, and refine the estimates. 

A substantial literature on these interventions is not provided below; part of the project is to find it. GiveWell’s intervention reports are a useful resource.

Attempting this cost-effectiveness analysis raises various methodological issues in addition to those already discussed in area 1 above, namely: 

• How do we combine various studies, which have different locations, size, outcomes measure, etc. into a single estimate? What sort of quantitative reductions are justified for various qualitative differences? 
• What is the most defensible way to account for total per-person effects over time? Interventions plausibly have some impact for several years, but studies generally only measure outcomes directly after the intervention.

We welcome collaboration with researchers who can help improve our analysis. 

In the years to come, we want to expand our analysis in two directions. First, to systemic interventions that private donors could fund, such as public health campaigns to prevent, rather than treat, mental illness.  Second, to consider which public policies governments should adopt, given limited budgets, to most effectively increase the wellbeing of their populations.

Area 3: Understanding the wider global priorities context 

Our research implicitly aims to improve the lives of people living now or in the near future, i.e. the next 100 years or so. Alternatives to this are, schematically, to focus on benefitting  (1) sentient life over the long-run and (2) non-human animals (hereafter ‘animals’) in the near-term. Hence, if and when we determine the most cost-effective means of helping people in the near-term, we can still ask: How important is this, relative to the alternatives? This is the subject of area 3.

3.1 Longtermism

A recent and increasingly popular idea in global priorities research is longtermism, the view that the primary determinant of how much good our actions will have are their effects over the very-long run, rather than within our lifetimes (Greaves and MacAskill, 2020). If true, may imply a radical reorientation of priorities for society at large, including the Happier Lives Institute.

Greaves and MacAskill (2020) have recently articulated the case for ‘strong longtermism’ and argued that it is true on a wide variety of empirical and ethical assumptions. This raises the question: under which assumptions, or sets of assumptions, longtermism is not true?  Subsequent work could then ask: How plausible are these (set of) assumptions? This is a primarily theoretical task we think merits closer examination.

One, amongst many, specific angles to explore is the significance to longtermism of worldview diversification, the idea that altruistic agents should diversify their resources across different interventions or areas depending how strongly they believe in each ‘worldview’ (Karnofsky, 2016). If this were correct, it would imply agents should allocate some, but not all, of their resources to both near-term and long-term projects.

Worldview diversification is sometimes regarded as a candidate solution to moral uncertainty (the problem of what we ought to do when we don’t know what we ought to do); however, it’s attracted almost no attention in the philosophical literature on moral uncertainty. Is there a plausible justification for worldview diversification? What would it imply, practically?

Supposing longtermism is true, what are its implications? How reasonable is HLI’s current project—researching how to measure and increase wellbeing, aimed at impact in the near-term—from the perspective of longtermism? Presumably one valuable, although not necessarily urgent, longtermist project would be determining how to increase the quality of lives over the long-term. Can an understanding of subjective wellbeing literature inform that task and, if so, how valuable might this analysis be? A preliminary thought is that, as noted above, economic and technological growth may do little to raise aggregate wellbeing, and hence making lives go better will require deliberate study and intervention.

3.2 Animal welfare

A natural challenge with doing the most good, where animals feature, is our ability to be able to make unit comparisons of welfare changes between different species. For instance, how do we determine the level of suffering of animals in factory farms compared to both each other and to the level of happiness (or suffering) that humans experience? Note, the challenge of interspecies comparisons also arises for longtermists when comparing current humans to sentient computers or genetically-modified descendants of humans.

If we assume subjective wellbeing scores are the least worst measure of wellbeing for humans, what does this imply, if anything, for whether and how to compare humans to animals, who cannot make such self-reports? Perhaps it will be illuminating to consider under what assumptions it is reasonable to make cardinal comparisons among those able to give self-reports (see 1.2.3) and then assess whether those assumptions persist across species.

Concluding remarks

We want to see a world where everyone lives their happiest life. To do that, we conduct and promote research into how best to measure and increase global wellbeing. This document has set out the broad range of topics this research draws on and, further, has specified what we take the priorities to be for ourselves and fellow researchers who share our goals.
