In this post, I discuss how to assess the nature of a field of research and its differences from other fields. I focus on futures studies and discuss whether the approaches of futures studies are intellectually unified and whether there is some minimal unity in the field. I use the term “intellectual” to highlight to principled nature of my analysis in contrast to possible analysis of institutional or experienced unity of futures studies. The focus is on how different approaches of futures studies produce knowledge. The intellectual unity concerns what similarities and differences there are in the ways in which knowledge is produced. Although social and institutional aspects affect this, as sociology of science has shown, the social and institutional aspects are not at the core of the issue and cannot be discussed in this post.

Four levels of unity

Roughly, the question of intellectual unity concerns the unity of a field in terms of

(i) the goals of the field,

(ii) the objects of study, i.e., what phenomena are studied,

(iii) methods of the field,

(iv) theories in the field.

Later I provide a more nuanced n-dimensional space in which a field of research can be located. However, by going through these four aspects, we can begin to conceive how nuanced issue the intellectual unity of a field is. I begin my discussion without mentioning issues in futures studies so that our pregiven ideas of the intellectual unity of the field do not affect the way we conceive the analysis below.

Goals

By goal, I mean the overall need that a field of research attempts to satisfy, be it epistemic or practical (or both). Identifying a goal of a field is a somewhat difficult task, conceptually speaking. First, what intentions decide what the goal of a field is? Is it something that the practitioners consider as the goal or is it a rational reconstruction on the basis of the general working of the field (methods, objects, and so on; see below)? Different people may associate different goals with their research, and it is not quite obvious how a rational reconstruction would be constructed. For example, Newton’s work had close connections to theology, but we can still attempt to make sense of his physics in terms of goals that are related to the study of the laws of nature, not God.

Nevertheless, there are nontrivial differences between the goals of different fields. For example, one could say that physics attempts to describe the fundamental nature of reality or to capture the universal laws that govern phenomena. Physics does not attempt to capture the nature of divine will, no matter what some practitioners think of their work. On the other hand, psychology attempts to understand human cognition and behavior, not the fundamental nature of the universe or universal laws.

Moreover, we can identify a shift in goals in a field of research. For example, behavioral psychology attempted to capture patterns in stimulus-response series and thus predict and control human behavior (Watson 1913). On the other hand, cognitive psychology attempts to capture mental processings that explain human behavior.

Objects of Study

By objects of study, I mean the phenomena that a field investigates. These phenomena may be real word phenomena, or they may be something that is conceived by the field to count as real phenomena. For example, there is no real phenomenon that astrology studies, but we still wish to be able to identify its objects of study (the effect of celestial objects on specific details of human life).

Objects of study are closely related to the goal of a field, but the goal of the field cannot be defined simply as “understanding set S of phenomena”, where members of S are the objects of study. For example, understanding human behavior is a goal that does not, in itself, tell what needs to be studied. It is an empirical issue what features of the world determine behavior. Currently, psychology attempts to understand phenomena such as memory, attention, problem-solving, and so on. These are its objects the study and these phenomena are thought to answer questions about human behavior. On the other hand, behavioral psychology also attempted to understand human behavior, but its objects of study, such as conditioning, were different and more limited.

Different fields can also have the same objects of study but different goals. For example, philosophy of science may attempt to understand a historical episode in science in order to understand how scientific theories are tested (and thus the epistemology of science in general) while sociology of science may attempt to understand the same episode in order to understand power structures in science (and thus the social structure of science in general).

Methods

By methods, I mean the somewhat detailed procedures that are used to gain knowledge of the objects of study. (In contrast, I do not consider abstract descriptions of evidence-theory relations, such as falsificationism or HD-model as “methods”). For example, psychology can conduct all sorts of experiments to study issues related to memory, and historiography can trace events in the past by critically evaluating documents in archives.

Different objects of study require different methods. For example, one can hardly experimentally reconstruct the historical path of events, and one cannot investigate the effectiveness of a drug through interviews. Usually, methods are chosen in terms of the presumed features of objects of study. However, there are situations where not enough is known about the objects, and different methods are used in the hope that the objects have the features that make the method suitable (for example, De Baerdemaeker 2021 calls experiments with this feature method-driven experiments). 

Different goals also affect what methods are used. For example, if one wishes to have an effective drug for a widespread health problem, RCT is the preferred method to study the effects of a drug. If the goal is to understand the cultural impact of a drug, other methods must be selected. An interesting question is whether the effect of different goals on methods is always mediated by a difference in the objects of study that the goal implies. Prima facie, it seems that this is not the case. For example, philosophers and sociologists can study theory acceptance in science but they do this in different ways. Sociologists may conduct participant observations while philosophers may rationally reconstruct a scientific phenomenon. To say that the objects of study are different because sociologists focus on the social nature of theory acceptance while philosopher focus on the conceptual nature of theory acceptance seems a mere semantic trick. Be that as it may, the important thing to notice is that goals affect methods, and we can leave open the question of whether this is mediated by objects of study.

Finally, we begin to see an issue that is discussed in more detail below: Goals, objects, and methods come in tight packages. This means that if one is to dismiss a method – something that is often suggested when claims about “what counts as a really scientific way of inquiry” are made – one also needs to conclude that some goal is not worth satisfying and some objects are not worthy of study. I think this would be a mistake in many cases. We cannot be hostages of a set of methods. Rather, we need to create methods that satisfy our goals and help us to study the objects we are interested in. Otherwise, there would be no point in developing better methods. Sometimes we cannot get what we want. For example, sometimes it is impossible to investigate a phenomenon and hope that we achieve generalizable models. Historical methods are suitable in tracing events in the past but, given the rather unique nature of many of these events, – something that historians are trained to handle – we are not able to find generalizable insights comparable to those provided by RCTs.

Theories

I use theories in a wide sense to cover claims that a field makes about the world. These claims may either be assumptions, based on previous research or some other source, or results of research. Obviously, the theoretical level is often the product of methods, objects, and goals. The results of the research are aimed at satisfying a goal by studying certain objects with certain methods. However, often the results are not able to satisfy the goal. This is the case, for example, when the Michelson–Morley experiment failed in its attempt to detect the luminiferous ether. Sometimes a field of research does not only fail to satisfy a goal but is rather completely unable to do so. For example, behaviorism is rather limited in its attempt to describe different types of learning processes that go beyond reinforcement and punishment.

Often a theory also determines what objects are studied and what goals are set. For example, the models in quantum physics determine what objects are studied and how: the experiments with LHC investigate high-energy interactions between particles. Sometimes the theoretical frames are rather far away from the concrete research but still shape it. For example, different assumptions about structural and individual determinants of history shape what type of objects are studied in historiography.

There is no fundamental separation between theories and other aspects of research. It is not the case that we could have a goal-object-method constellation that is completely theory-free and only a means to create a theory. All research requires background assumptions about how the relevant domain works. Nevertheless, there are differences in the strength and justification of these background assumptions. Some assumptions are based on previous research while others, at the other end of the spectrum, are based on subjective and biased ideas concerning a domain.

Back to Futures Studies

Before complicating things even further, it should already be clear that intellectual unity can be sought from different levels mentioned above. However, it is unclear whether unity at any level is, in fact, relevant to the liveliness and identity of a field.

First, one might seek unity in goals. One could say that futures studies is unified in that it attempts to understand possible and desirable futures. However, many scholars focus on people’s (and structural) views on the future. The goal seems to be to understand, and perhaps improve, how people think about the future. These two goals are not related in any trivial way. Of course, there could be a link in that the thinking about the future affects it and tells what is desirable. However, this link requires substantial theoretical assumptions about the determination of future and its desirability, i.e., that the future is created through explicit cognitive acts and that the desirability of a future can be decided by the current values. We see that seeking unity in goals forces us on theoretical considerations.

Moreover, shared goals do not seem enough to unify a field. Different people may share a goal and disagree fundamentally on how to achieve to goal. Astrology attempts to understand human behavior (and futures!) but it cannot be associated in any meaningful sense with cognitive psychology which has the same goal. Even if different branches share the same goal, their assumptions about the creation of futures and the methods they use can differ greatly.

Secondly, one might attempt to find unity in the objects of study. However, it is tricky to say what are the objects of study in futures studies. One might claim that the objects are possible futures, present images of the future, future-oriented practices, and so on. It is unlikely that there could be unity on this level in futures studies. More fundamentally, the suggestions are not detailed enough. For example, physics does not study “fundamental things” but electrons, quarks, bosons, and so on. It is unclear whether there is such a detailed set of objects that could be said to constitute the core objects of study in futures research. Different projects in futures research focus on different types of objects: Futures of education, futures of technology, futures of economy, and so on. It is plausible that these objects require different methodological and theoretical treatment from each other.

Comparison with historiography is useful here. There is no such thing as historiography simpliciter. There are historiographies of various things. Historiography of science differs from historiography of population, and historiography of emotions differs from military historiography, even though the fields can overlap. It is unlikely that we can find intellectual unity in historiography in its objects of study. Perhaps we could say that it investigates the traces of the past (and that futures research studies the traces of the future, i.e., indications) but this would move the question of unity to a different level: Are the traces investigated in a similar manner in different approaches and are the conclusions drawn similar in their nature across different branches of historiography? It seems that they hardly are similar.

This pushes us towards asking about the methodological unity of futures studies. It seems that there is no unity on this level. Futures studies is notorious for its tendency to develop and use methods while theoretical considerations lack behind. However, the question is not quite so quickly answered. Clearly, not all methods that tell us about the future are methods of futures studies. For example, experiments in LHC are not futures studies even if they inform us about the future structure of fundamental domains. It might be the case that many important methods in futures studies are unified in some way. For example, it might be the case that the methods of futures studies, such as Delphi, share the assumption that human sense-making practices track what could happen in the future and thus utilize the sense-making practices in one way or another to produce presentations of futures. However, even if such methodological unity exists, it is unclear whether it would unify the field. The same methods could be used to investigate many types of objects and to satisfy several goals – especially if the methodological unity is defined in a rather abstract sense like I did above. For example, one method could serve both to reinforce a successful global business and to emancipate the futures of marginalized groups. Given that futures studies often emphasizes that (i) it is a field where values play a role, and (ii) it is a field where the research shapes its object, it would be remarkable if it was conceded that futures studies is simply a family of similar methods, no matter how different the goals of the use of the methods are. This downplaying of value-judgement related to the goals of research would go against the spirit of futures studies.

Finally, one might attempt to find unity at the level of theories. This would be a rather natural place to search for unity. If a field shares a view on the world to which different studies attempt to contribute, there seems to be unity in the field. However, it is dubious whether there is such theoretical unity in futures studies, as there are not too many theories and even the concept of theory in the field is somewhat obscure: Usually, theories describe the objects of study in a field of research. However, we have seen that either (i) it is unclear what the objects of study of futures studies are; or (ii) or the objects of research consist of an extremely heterogeneous set of phenomena. Surely, there have been attempts to define the theories (and thus the objects of research) in futures studies. For example, Fergnani and Chermack (2020) argue that futures studies should develop theories about futures and foresight interventions and empirical data to test such theories. If executed successfully, such a research project could set a unified theoretical basis. The fundamental problem is that futures studies is much more than a mere study of futures and foresight capabilities and interventions. The theoretical unity would come at the cost of cutting off several central parts of futures studies. The paradox is that futures studies seems such a heterogenous field that any attempt to find theoretical unity in it seems doomed to destroy the heterogeneity that characterizes the field. The field whose unity we seek ceases to exist if we determine its theoretical unity.

Ecosystems in Research

Finding intellectual unity in a field of research is made more difficult by the fact that different subfields or approaches are constituted by an interrelated set of goals, objects of study, methods, and theories. I call these tight wholes ecosystems, as each component nurtures, and is nurtured by, other components. Ecosystems are like small-scale paradigms in the Kuhnian sense. Criticism of an ecosystem may come from outside by denying the feasibility of any component. However, as the components are interdependent, the criticism only works if also other components are criticized or abandoned. If one has a certain goal and therefore studies certain objects, the feasibility of the choice of objects can only be denied by abandoning the goal. This can of course happen. For example, even if we wish to understand human behavior, we should not study astrology even if it was the only way we could study the behavior. The goal would have to be abandoned as there would be no means of satisfying it. However, the criticism of a component is not usually as straightforward as in the example, as the components of research are usually not as obviously unfeasible as in astrology.

To illustrate the issue, consider an ecosystem in futures studies, Causal Layered Analysis (CLA). The goal of this approach is to open “up the present and past to create alternative futures” and to reveal “deep worldview commitments behind surface phenomena”. Its objects of study are the deep cultural and social conceptions that shape the visions of the future that people and societies hold and how these conceptions are constructed and structured. The method is to analyze four levels that constitute a discourse: litany, causality, worldview, and myth and metaphor. The theoretical frame is provided by poststructuralism: “epistemes or structures of knowledge [–] frame what is knowable and what is not, which define and bind intelligibility” (Inayatullah 1998, 817).

The components of CLA are naturally connected. For example, the goal and the theoretical frame support the object of study. If we wish to create alternative futures and if we think that intelligibility and knowledge depend on deep structures, it is natural to dig into the deep cultural and social conceptions layer by layer. The study of these conceptions can widen what is intelligible and thus the set of alternative futures. Moreover, if we accept that cultural and social conceptions are important objects of study and if we accept the poststructuralist view, it is natural to assume that the method has to analyze the many and deep layers in our discourses.

Imagine someone wished to “clean up” futures studies postulating a set of goals, objects of study, methods, and theories that should constitute the common backbone for the field. If any of the components of CLA was washed out during the process, it is unclear how the other components would survive. Moreover, it is unclear how the criticism of any one component would shake CLA. For example, if the goal was criticized, other aspects would probably save it by pointing out that the method, objects, and especially the theory suggest that the goal is worthwhile. In conclusion, it seems that (i) different approaches in futures studies cannot be brought closer together by unifying the field in a piecemeal manner at some level (as the levels are interconnected within different approaches), and (ii) different approaches can stubbornly defend themselves in the face of imperialistic attempts to define what “really” counts as futures research.

Finally, the phenomenon of ecosystems implies that there is no answer to the question of which of the elements comes first. There is no natural way of choosing a goal, object of study, method, or theory independently of other elements. Moreover, it must be noted that the elements also develop in time together. For example, changing goals and objects of study require new methods, and changed methods may introduce further changes in objects of study.

Locating a Field of Research among Sciences

There are many dimensions according to which we can locate a field of research with respect to other fields. In what follows, I discuss five such dimensions. The list is far from exhaustive but illustrates the complexity of the issue.

1. What objects are studied? Different fields can be more or less distant from each other depending on what kinds of objects are studied. For example, one traditional distinction has been between human and natural sciences. However, this distinction is perhaps not the most adequate one. For example, historical natural sciences, such as geology and paleontology, are rather close to historiography in many respects because they study singular token events and processes, even though they do not study humans. This leads us to the next point.

2. What kinds of (re)presentations are produced? For example, some fields provide theories in a strict sense while others provide narratives. Consider, again, the human vs. natural sciences distinction. The distinction is problematic because there are theoretical sciences in both human and natural sciences (for example, macroeconomics is a rather theoretical science) and because there are narrative sciences in both human and natural sciences (for example, paleontology is a rather narrative science). We should note that the types of objects that are studied shape what kinds of (re)presentations can be provided. Fields that study singular (token) events are more naturally narrative sciences, and fields that study repetitive (type) events are more naturally theoretical sciences. This leads us to the next point.

3. What kinds of explanations are produced, if any? Roughly, there are nomological explanations that are based on lawlike generalizations. Physics provides such explanations. Then there are mechanistic explanations that identify entities and activities that produce an outcome. Medicine provides such explanations. There are narrative explanations that describe a sequence of events and turning points that led to an outcome. Historical sciences provide such explanations. Finally, there are intentional explanations that explain actions in terms of beliefs, desires, thoughts, and so on. Historiography produces such explanations. I leave open the conceptual core of each type of explanation and their relations to each other. However, different types of explanations are associated with different types of (re)presentations that a field provides. For example, nomological explanations are more natural in theoretical science while narrative explanations are more natural in narrative science. Yet, the association is not so straightforward. For example, it might be that narrative explanation can be understood in terms of mechanistic explanation. If so, medicine and historiography differ in the representations they produce (medicine does not produce narratives) but share explanatory practice (mechanistic explanation).

4. How is evidence produced? This is the first aspect of methodology. For example, one can perform experiments. The experiments might be detailed and nuanced, such as the ones in particle physics, or they might be a rather hands-on type, such as the ones in experimental archeology. On the other hand, some fields are based on observation, such as astronomy, and some fields often use observational studies due to practical or ethical issues. Some fields do not belong to any such straightforward class. For example, historiography often produces evidence through processing archival materials.

5. How is evidence interpreted? This is the second aspect of the methodology. For example, many fields are based on statistical inferences. These fields are marked by their ability to produce sets of data in numerical form. On the other hand, some fields are based on interpretation. For example, historiography infers beliefs, feelings, intentions, and so on from their sources. However, the workings of any field are hardly captured by these classical ideas of clear-cut scientific methodology. For example, experiments in physics involve both heavy statistical processing and deductive reasoning on the theoretical level. In historiography, one does not simply interpret the sources, but the process involves different types of reasoning on different levels. For example, knowledge of geology and demography is often essential to understand the meaning and implication of the sources.

Locating Futures Studies?

It is difficult to answer these questions with respect to futures studies. It seems that different approaches in futures studies require different answers. For example, one can study future images and even explain them. Such research is often based on interviews or Delphi and provides a description of future images of certain people or groups. Or one can study future consciousness with a psychometric scale and use it to explain “people’s perceptions of and reactions to the pandemic” (Lalot et al. 2021; see also THIS interesting work). On the other hand, one might construct a set of alternative futures on the basis of a deconstruction of textual sources. There are many issues here that would require clarification. What kind of (re)presentation a scenario of an alternative future is? Is there anything to be explained? How, exactly, does the methodology work? I am not suggesting that there are no answers or that there is anything suspicious here – I am a great fan of alternative futures. The point is that such research is rather difficult to locate in relation to other fields of research.

The problem in locating futures studies and thus searching its unity goes back to the heterogeneous objects of study in the field. As we have already touched upon, there are several things that futures studies can study, among them:

1. What do people (individuals, groups, and organizations) think about the future?

2. How do people make sense of the future?

3. Where would the current dynamics lead us (individuals, groups, or organizations) if they continue?

4. What should be done if we would like society to develop differently?

It is quite likely that different levels of futures studies differ with respect to their basic nature. For example, Niiniluoto has suggested that futures studies is a design science. In these sciences “results typically express relations between means and ends” (2002, 375). This would capture item 4 and perhaps item 3 on the list. On the other hand, Fergnani and Chermack (2020) have suggested that futures studies should develop theories about futures and foresight interventions and empirical data to test such theories, i.e., “generalizable scientific theories on why, how, when, and where futures and foresight capabilities and interventions work.” This idea captures a mixture of levels 1 and 4. It seems difficult to find a definition of futures studies that would capture all items in the list in a non-ad-hoc manner. It follows that there is no shared definition that could be used as the base for defining different aspects of futures studies.

Approaching Minimal Unity

In my view, futures studies is a modal science and studies possibilities. I follow here the canonical suggestion that futures studies study possible and desirable futures and our conceptions of them (Amara 1974; Bell 2009). An essential component in the mapping of futures is the critical study of our own conceptions that ground different scenarios of the future (Bell 2009; Inayatullah 1998). The interplay between understanding possible futures and the critical study of our conceptions about the future is captured best by the notion of alternative futures that has been a guiding concept in futures studies (see Slaughter 2020). Future scenarios should be varied and we should create scenarios that challenge the ones that we take to be most natural or plausible.

This means that futures studies provides scenarios that describe possibilities, and it can produce such scenarios with multiple methods. Scenarios can be presented in many forms: For example, they can be static descriptions of future states of affairs, or they can have a narrative form. While there are no explanations in futures studies, strictly speaking, the construction of scenarios has an interesting relationship to explanatory practices, especially in historical sciences. Many explanations are modal. They describe what would have happened, had things been different. Such explanations require scenarios of counterfactual pasts against which we can compare the actual turning points of the history. For example, to say that tensions in the Balkans explain WW1 is to say that in a scenario without tension the war would not have broken out. Scenarios of possibilities are not a unique device of futures studies but connect futures studies to a family of sciences. Even if there are no explanations in futures studies, there are similar important modal inferences.

It is crucial to notice that the above said does not mean that other ways of understanding futures studies are redundant or erroneous. How people think and make sense of the future, the actual dynamics of the world, and so on are legitimate objects of study. However, I would suggest that these approaches are derived, conceptually speaking, from the idea of futures studies as a modal science. First, the study of cognitive processes and cognitive results (e.g., future images) related to the future assumes that human beings are able to construct scenarios of the future. Moreover, it makes sense to study these cognitions only if they are an important aspect of human life. And they are: human cognitions about possible futures are relevant for possible futures. The study of future-related cognition assumes that there are real future possibilities that cognitive processes can track and achieve more or less adequately. This leads to the second point: There are future possibilities that are ontologically independent of what any particular person, group, or society thinks. No matter how much we know about how the future is thought about, there always remains the question of whether the thinking is correct and whether it could be improved. The most obvious indication of this is that we often fail to see the actual future among the possible futures. The study of cognition about possible futures does not exhaust the study of possible futures but belongs to it.

There is intellectual unity, then, in the commitment to the realness of future possibilities. There are no futures studies where this commitment is not present. We wish to know and map future possibilities. This means that there are methods that are not focused on predicting the future; the actual future is only one possibility, as it were. However, as we come to recognize how difficult the task is and how humans shape their future, there must be studies of cognitive processes and results (such as future images) that are related to the future. However, as said, this type of inquiry is derived from the idea that there are real future possibilities that need, and can, be mapped.

This leads us to the final point. As already mentioned above, “the future” is not an object of study in the same sense as elementary particles or the history of rock music. When we study the future, we study the future of something – or rather: possible futures – future of work, future of infrastructure, future of science, and so on. It is important to notice that such phenomena are studied in other disciplines, and the differences between disciplines are reflected in futures studies. Futures studies is an essentially interdisciplinary field. Knowledge and methods from other fields inevitably leak into futures studies. This also means that much of the theoretical understanding in FS is borrowed from other fields.

However, futures studies seems to have minimal unity in that it develops the knowledge and know-how of other fields further by taking into account factors, obstacles, and uncertainties that affect and shape what can be said about the future on the basis of our current understanding. I call this aspect of futures studies implicit problem recognition. Futures studies are united in the ability of implicit problem recognition when it comes to ideas and thinking about the future. We can compare futures studies to historiography in this regard. “History” as such is hardly ever the object of study. Rather there are histories of something (historiography of science, historiography of economy, and so on). Historians are experts in the possible difficulties in understanding the past. For example, they are aware of how the availability of sources is shaped and how it affects the research. They also know how easily present conceptions are projected in the past and how difficult it is to communicate past ways of thinking to current audiences. Analogous things are true of futures studies. There is awareness of what knowledge and information are available and how it shapes the understanding of the future. There is also understanding of how futures might be different to extent that we have difficulties in grasping them in explicit terms.

So, there is intellectual unity in (i) the commitment to the realness of future possibilities and their relevance to the present concerns, and (ii) implicit problem recognition. Given this minimal unity, it becomes understandable why futures studies focus on seemingly different topics, ranging from people’s ideas about the future to the planning for desirable future (mentioned earlier). Thinking about possible futures tracks and affects possible futures, and there is no closing the distance between the two unless we are aware of the problems involved. Both possible futures and our thinking about them need to be studied in order to understand the multilayered relationship between the two. In between the two poles lies the implicit problem recognition.
