In this post, Victor Lange and Thor Grünbaum discuss the article they recently published in Ergo. The full-length version of their article can be found here.

Many of us think that decisions and actions are justified, at least partially, in relation to how they affect the well-being of the involved individuals. Consider how politicians and lawmakers often justify, implicitly or explicitly, their policy decisions and acts by reference to the well-being of citizens. In more radical terms, one might be an ethical consequentialist and claim that well-being is the ultimate justification of any decision or action.

It would therefore be wonderful if we could precisely measure the well-being of individuals. Contemporary psychology and social science contain a wide variety of scales for this purpose. Most often, these scales measure well-being by self-reports. For examples, subjects rate the degree to which they judge or feel satisfied with their own lives or they report the ratio of positive to negative emotions. Yet, even though such scales have been widely adopted, many researchers express scepticism about whether they actually measure well-being at all. In our paper, we label this view measurement scepticism about well-being. 

Our aim is not to develop or motivate measurement scepticism. Instead, we consider a recent and interesting reply to such scepticism, put forward by Anna Alexandrova (2017; see also Alexandrova and Haybron, 2016). According to Alexandrova, we can build an argument against measurement scepticism by employing a standard procedure of scientific psychology called construct validation. 

Construct validation is a psychometric procedure. Researchers use the procedure to assess the degree to which a scale actually measures its intended target phenomenon. If psychologists and social scientists have a reliable procedure to assess the degree to which a scale really measures what it is intended to measure, it seems obvious that we should use it to test well-being measurements. For the present purpose, let us highlight two key aspects of the procedure. 

First, construct validation utilises convergent and discriminant correlational patterns between the scores of various scales as a source of evidence. Convergent correlations concern the relation between scores on the target scale (intended to measure well-being) and scores on other scales (assumed to measure either well-being or some closely related phenomenon, such as wealth or physical health). Discriminant correlations concern non-significant relations between scores on the target scale and scores on scales that we expect to measure phenomena unrelated to well-being (e.g., scales measuring perceptual acuity). When assessing the construct validity of a scale, researchers evaluate a scale by considering whether it exhibits attractive convergent correlations (whether subjects with high scores on the target well-being scale also score high on physical health, for example) and discriminant correlations (e.g., whether subjects’ scores on the target well-being scale have significant correlations with perceptual acuity).

Second, the examination of correlational patterns depends on theory. Initially, we need a theory to build our scale (for instance, a theory of how well-being is expressed in the target population). Moreover, we need a theory to tell us what correlations we should expect (i.e. how answers on our scale should correlate with other scales). This means that, when engaging in construct validation, researchers test a scale and its underlying theory holistically. That is, the construct validation of the target scale involves testing both the scale and the theory of well-being that underlies it. Consequently, the procedure of construct validation requires that researchers remain open to revising their underlying theory if they persistently observe the wrong correlational patterns. Given this holistic nature of the procedure, correlational patterns might lead to revisions of one’s theory of well-being, perhaps even to abandoning it. 

The question now is this: Does the procedure of construct validation provide a good answer to measurement scepticism about well-being? While we acknowledge that for many psychological phenomena (e.g., intelligence) the procedures of construct validation might provide a satisfying reply to various forms of measurement scepticism, things are complicated with well-being. Here the normative nature of well-being rears its philosophical head. We argue that an acceptable answer to the question depends on the basic assumptions about the methodology of well-being theorising. Let us clarify by distinguishing between two methodological approaches.

First, methodological naturalism about well-being theorising claims that we should theorise about well-being in the same way we investigate any other natural phenomenon, namely, by ordinary inductive procedures of scientific investigation. Consequently, our theory of well-being should be open to revision on empirical grounds. Second, methodological non-naturalism claims that theorising about well-being should be limited to the methods known from traditional (moral) philosophy. The question of well-being is a question about what essentially and non-derivatively makes a person’s life go best. Well-being has an ineliminative normative or moral nature. Hence, the question of what well-being is, is a question only for philosophical analysis.  

The reader might see the problem now. Since construct validation requires openness to theory revision by correlational considerations, it is a procedure that only a methodological naturalist can accept. Consequently, if measurement scepticism is motivated by a form of non-naturalism, we cannot reject it by using construct validation. Non-naturalists will not accept that theorising about well-being can be a scientific and empirical project. This result is all the more important because many proponents of measurement scepticism seem to be methodological non-naturalists.  

In conclusion, if justifying an action or a social policy over another often requires assessing consequences for well-being, then scepticism about measurement of well-being becomes an important obstacle. We cannot address this scepticism head-on with the procedures of construct validation. Such procedures assume something the sceptic might not accept, namely, that our theory of well-being should be open to empirical revisions. Instead, we need to start by making our methodological commitments explicit.

Russ Colton – “To Have A Need”

A man is hanging from the hand of a clock fixed on the exterior wall of a six-story building, risking his life.
Harold Lloyd in the 1923 movie “Safety Last!”

In this post, Russ Colton discusses the article he recently published in Ergo. The full-length version of his article can be found here.

Every day we notice the needs of ourselves or others and are moved to address them. We often feel obliged to do so, even for strangers. Whatever is needed seems important in a way that perks and luxuries do not. Some philosophers take such observations quite seriously and give need a key role in their moral and political theories. Yet they characterize the concept of need differently, and sometimes not very fully. To help us understand and assess their ideas—but also just for the sake of improving our understanding of a common concept that enters into everyone’s practical and moral thinking—I want to try to say as clearly as possible what it means to have a need. My paper is focused on this task of conceptual clarification.

Throughout, I am concerned with a certain kind of need—welfare need, as I call it, which is the need for whatever promotes a certain minimum level of life quality, like the need for air, education, or self-confidence. This differs from a goal need (aka “instrumental need”), which is a need for whatever is required to achieve some goal—whether that goal is good for you or not—like the need for a bottle opener or a bank loan.

It is well-known that sometimes we say a person needs something when they have neither a welfare need nor a goal need for it: for example, “The employee needs to be fired.” In such cases, however, we can readily deny that the person has the need—the employee does not have a need to be fired. By contrast, in cases of welfare or goal need, the person has the need. Thus, insofar as we are interested in need because of its connection to human welfare, the specific concept of having a need may be more important than needing, which is why I focus on the former. In considering examples that test my analysis, it is best to think in terms of having a need.

Among philosophers, perhaps the most popular gloss on welfare need is this: to need something is to require it in order to avoid harm. This idea is approximately correct, but it needs improvement. The relevant notions of requirement and harm must be pinned down, and the idea must be broadened, since people also need what is required to reduce danger, like vaccines and seatbelts. To make these improvements, I offer two analyses of having a need—one that captures the original intuition about harm avoidance, and a broader one that captures the concept in full by covering both harms and dangers.

David Wiggins (Needs, Values, Truth) is the only theorist who has tried to clarify with precision the requirement aspect of the harm-avoidance idea. In broad strokes, his view is this: I need to have X if and only if, under the present circumstances, necessarily, if I avoid harm, then I have X, where necessity here is constrained by what is “realistically conceivable.”

This idea has a number of problems. One of the most serious arises when we have a need for some future X that will be unmet. If a non-actual X can count as realistically conceivable, there seems to be nothing preventing the non-actual possibility that, even without it, whatever harmful process was headed toward us is eventually thwarted by other means, leaving us unharmed. But that means I can have a need for X even though I could avoid harm without it.

Another problem is that often, when we’re in a pinch in a given circumstance, we view multiple things that could save us as needed. If I were short of money to pay rent at the end of the month, then each of the following assertions would be reasonable: I need more money in my bank account; I need a friend to lend me money; I need the landlord to give me more time. But on Wiggins’s necessity approach, given the circumstances, I can need only one X, which will have to be the disjunction of all potential rent solutions.

I argue that these (and other) problems are readily avoided with a counterfactual-conditional approach, along these lines: I have a need for something when, without it, my life would be (in some sense) harmed.

Understanding the relevant notion of harm requires attending to how we balance positive and negative effects on welfare over time. I explore this in the paper and conclude that when you have a need for something, your life from then on would be better on the whole, and less unsatisfactory for some period, with it than without it.

There will be different intuitions about what counts as unsatisfactory. My analysis is neutral, but I do make a case for the claim that for our most ordinary conception of need, the relevant sense of “unsatisfactory” is not good. With this idea in hand, my analysis implies a very natural idea: if you lack what you need, your life for a time will not be good and will be worse than it would otherwise be, and this loss will not be outweighed by any benefit.

Finally, I extend the analysis to our needs for what makes us safer, things without which we would be in more danger independently of whether we would be harmed. This is challenging because many present needs are for future benefits, and the risks relevant to our future welfare can change during the interval. Fortunately, there are easy ways to address the relevant issues so that the analysis remains quite simple. Roughly put: I now have a need for X if and only if it is now highly probable that, at the time of X, the expected value (quality) of my life from now on would, for some period, be less unsatisfactory with X than without, and would on the whole be higher.
