Abstract
Much current work in Science and Technology Studies inflects knowing with care. Analyses of the ethos of objectivity, and of the practices by which objectivity is crafted, have shown that knowing and caring cannot be thought apart from each other. Using case studies from our own work we analyse how, in the sociotechnical relationships that we study, knowing and caring are entangled through ‘attachments’. We appreciate – both in the sense of valuing or respecting and in the sense of evaluating or assessing – how the notion of ‘attachment’ invites re-imagining relations between the social and the technical, between knowers and objects known, and between sociotechnical work and the affective sensibilities that enable, and are brought to life by, such work. Our respective ethnographic engagements with dog-human relations, obesity surgery and dementia care demonstrate that it is agents’ diverse and shifting attachments to technologies and techniques that shape the ways in which bodies, knowledge and practices form. The affects that arise in this process, or so we claim in neo-pragmatist fashion, are not preconditions to, but rather the result of such practices of attachment; rather than a prerequisite, they are an effect of the work of attaching itself. Thinking with attachments recognizes how techno-scientific work builds and shapes passions, aesthetics and sensory experience, allowing us to trace how varied sensibilities to what constitutes ‘the good’ come to be and come to matter in practices of relating between humans, animals and things.
Feminist epistemologies, ethnographic susceptibilities and praxiographical approaches to ontology have prompted scholars in Science and Technology Studies (STS) to take seriously bodies and mundane processes, to recognize the implications of their materialities and respect their fickle infidelities. As bodies come with quirks, materials with relations, and practices with uncertainties, these sensibilities bring under fresh scrutiny the ways in which connections within networks form and hold. As we address not only how things hang together but also how they fall apart, it is no longer sufficient to imagine connectivity in terms of forces, vectors, powers and bonds of greater or lesser strength. Such seemingly neutral concepts, signalling mechanics and calculatory logics, are belied by scholars’ and citizen scientists’ explorations of care, tinkering, intimacy and tacit knowing in laboratories, medicine and other science-related, day-to-day practices. 1
Calling out the ways in which the care that infuses such practices has historically been made invisible – pushed out of knowledge-making regimes and professional public life, and into the domain of the private, the domestic and the somatic (Latimer and López Gómez, 2019; Mol et al., 2010) – feminist STS scholars, in particular, have complicated ‘the pervasive bifurcations that prioritize the rational over the sensory and affective dimensions of knowledge’, by highlighting ‘the moral and affective economies that shape researchers’ entanglements with the phenomena they describe’ (Martin et al., 2015: 7). In other words, in the making of knowledge, care and normativities count.
If the feminist STS tradition has recognized that scholarly work and the knowing body are
Our framing matters. Where ‘thinking
From the cellars of ANT
Over the past twenty years, since it started to circulate in the vaults of the Centre
As a way into such relations, attachments continue to live within the CSI tradition of doing STS. In actor-network fashion, rather than taking on scientific knowing and the artefacts of technoscience, attachments inform observations of the mundane practices in which knowers and the objects of knowledge are co-construed. Music, drugs, wine – these are examples of ‘objects’ of appreciation that emerge while knowing and those that know are simultaneously in the making (Ávilá Torres, 2016; Callén Moreu and López Gómez, 2019; Gomart and Hennion, 1999; Mishra, 2020; Teil, 1998, 2012). Of such ‘making’, attachments are a crucial part: As serious, framing, effective (in the sense of ‘having an effect’) entanglements between humans and non-humans, attachments are constitutive of ecologies of knowledge. And if this literature on attachments deliberately orients itself towards unfolding sensibilities in the practices of lay persons, it picks up a concern within STS with the mundane procedures, situated performances and distributed expertise that mark expert knowing, as they do that of ‘amateurs’.
Perhaps its structural resonance with the recursive play of ANT imaginings has impeded attachment, as an analytical term, from traveling far beyond the SCI and French neo-pragmatist circles. Indicating ‘the co-creation of affinities, things, bodily engagements, and collectives that develops when a person or a group comes to strongly like [something]’ (D’Hoop, 2018), attachments rely on agents’ capacity to ‘be affected’. The very idea of attachment, then, flies in the face of the parameters by which knowledge and knowing bodies are framed. Originally proposed, according to Hennion, as an antidote to linear models of society-technology interactions where agency is staged as a centralized and active faculty of humans (and humans alone), the term attachment signals an ANT concern with the making of divides between the social and the technical, the human and the non-human, the affective and the objective realms. Highlighting not only the productive role of objects in such interactions, through its focus on mediation the term points out ‘forms of agency beyond the active/passive dualism’ (Hennion and Muecke, 2016: 300). If dismissed by some as an apolitical or amoral actor-network inspired attempt to distribute agency among humans and non-humans without attention to their moral and affective differences, we suggest that it is
Attachments and associations: A material-semiotic landscape
In the foreword to Despret’s (2016) collection of ‘scientific fables’,
Despret’s (2016) review of the work of ethologist Lorenz is a point in case. While ethological and other scientific practices typically rely on the notion that subject and object – here, human and animal under observation – are fixed, stable and separate entities, conventional representations of Lorenz’s ideas – according to Despret – systematically overlook the entanglements between the two.

The relational event is a matter of ontology, she suggests, rather than epistemology (or ideology): As the ethologist ‘studies’ the Jackdaw the bird becomes ‘Jackdaw-with-Human’ as much as Lorenz becomes the reverse. Complicating further the well-known ethological story of how the scientist gets to know the bird, she argues that his knowledge is only possible as the bird gets to know the ethologist.

Suggesting – and here the interest in the origins of the bifurcations shows up again – that the distinction between subject and object is the analyst’s preoccupation rather than the participants’ matter of concern, Despret argues that knowledge, object and subject are co-produced in a complicated process of mutual shaping through what we call attachment. In learning to be
The acknowledgement that entities and their (normative) positions become through the attachments of which they are a part turns thinking with attachments into a distinctive sociology, reworking ontologies of the social. Whereas in a classical Durkheimian sociology, social organization overlays the material world, in a framework that centres attachments, this world and its organization emerge in concert with one another. Stratifying society according to an
The mechanism that makes this reversal plausible in an ANT frame is the ‘association’ (in the literature sometimes used synonymously with ‘attachment’), which can be understood as any linkage of any sort. So, in a complementary set of early ANT papers tracing the connections between technologies and power differentials in 16th and 18th century colonial relations, Law (1986) and Latour (1986) explain how technologies of travel, navigation, collection and categorization
While the actor-network question of how relations enact social cohesion (rather than the reverse) has begun to inform STS theory at large, a focus on attachments places this question more explicitly at centre-stage. What if we were to think through Callon’s case as a making, unmaking and remaking of attachments? We might then say that, rather than the scientists failing to enroll the other actors in St Brieuc Bay, neither party has a firm grasp on how to relate, yet all clamour to engage their counterparts. It is the frivolity of the attachments in play, and the
In what follows, we develop moments from our own research to explore the additive value of thinking with attachments in connection with tried and tested STS themes, such as the ontology of the social, (nonhuman) agency and the work of the senses in knowledge practices. To the material-semiotic sensibility in the ANT tradition, which understands all things in the natural or social world as continuously generated effects of the web of relations in which they are located (Law, 2007), thinking with attachments adds an attention to the workings of sensing and care. Recognizing that this mode of thinking does not live in a vacuum, we have roughly mapped the material-semiotic landscape in which attachments live. In Despret’s additive spirit, we do not mean for the term attachment to
Relating reflexively
Within this landscape, our own work attends to various forms of care, which we understand as a set of reflexive relationships: shifting sensibilities, sensitivities, concerns and interventions that the work of attachments holds together. It is not sufficient to recognize that norms and values inform analysis; our proposal to think with attachments implies that the practices of our analyses shape the norms, values and passions that we carry forth. Taking attachments seriously, we must acknowledge that entities, including researchers and their normative positions,
That our analytic practices have such effects is perhaps what Martin et al. (2015: 11) mean when they suggest that normativity is among ‘the very conditions of possibility for care’. We wonder, however, whether the caring attitude of the researcher – ‘a person who cares must first be willing and available
The political power of thinking with attachments, then, lies in recognizing the play of stability and flux, in its invitation to observe the elements that are in play, sort through their relative qualities, valences and forms, and attend to the normative effects of specific attachments in the particular and temporal circumstances of the setting at hand. If care is characterized by practical negotiation and tinkering between heterogeneous ‘goods’ and ‘bads’ (Mol et al., 2010), then attachment refers to the embodied processes of qualification and valuing that animate such practices; it demands care for the premises, normativities and unarticulated but productive assumptions that infuse not only the practices of care but also those of care studies. In this way, or so we suggest, thinking with attachments asks us to observe the work of relating that constitutes the landscape of our research engagements and, in doing so, contributes to an emerging attention to being-as-relating as a salient theme in our field. As thinking with attachments begins to inform ethnographic work in technology, medicine, care and mundane practices involving knowing and technoscience, it inspires taking account of bodies, affectivity, valuation and normative dispositions in ways that eschew pitting the rational against the affective. Observing attachments in action and at work so calls attention to the shifting contours of the research space as it develops. More saliently, perhaps, it calls for an account of how one’s own normative and intellectual commitments build in concert with the attachments that one forms as a researcher, an observer and a participant in that space.
Lead or leash? Ontology of a social
What holds things together? Togetherness is the question rather than the premise of sociologies of association (Callon, 1984; Latour, 2005) and attachment (Gomart and Hennion, 1999). Both frameworks for understanding socio-technical relations take as their point of departure a social in-the-making and unknown. Social stabilities are wrought and strange; permanence is the exception, rather than the norm and it is a temporal effect of the research engagement itself. Such efforts to develop a non-tautological approach to the social – a social that includes power, empire and explicitly the ‘human mind’ – do not imagine this social as a set of determining relationships but rather as their result and they bring the work of relating squarely into view. Understood not as a separate metaphysical sphere, nor as a known set of realities, but as a shape-shifting network that emerges as humans and nonhumans connect – or get attached – the social is a work in progress of which there is no end in sight. 6 This work crafts coherence, and it includes efforts of maintenance and care. These are heterogeneous efforts that have to be made again and again, lest things come undone. Instead of taking the ‘social whole’ as what explains such ‘holding together’, it is precisely the sociologist’s presumption of togetherness that needs accounting for.
In its effort to account for togetherness, an approach that attends to attachments adds a concern for preferences, passions, effort, agencies and aesthetics in a way that working with associations might not quite allow. Foregrounding attachments acknowledges the material and differential mediations that produce the effect of being (or allowing oneself to be) moved. While associations demonstrate
In her current work De Laet (2021) considers the work of forming a pack with her animals, attending to the attachments that form, but also
If the leash suggests that leadership during a walk resides with the human subject, it more often than not shifts it to one or all of the dogs. They pause, they sniff, they equivocate, they circle back, inviting their human to follow them – as they know best what is interesting about the terrain. They are attached with and without the lead, though – if they persist in hanging back, their human can drop the leash and even without being tethered they will follow. As it coordinates the pack, the leash also crafts it; without it, another subject – that of humans and dogs freely attached – shows up. The pack, its individual subjects, and its blended ones, take many forms and every move of attaching creates new subject positions that subsume old ones without altogether dissolving them. Goods and bads are in play here: A disobedient or stubborn dog is bad, but so is a hectoring or impatient human; a dog happily running around freely, as long as her human is nearby and ‘in control’, is good – but so (for some) is a human who is firmly attached to a dog. Depending on the day, the moods, the weather and what transpired before, a walk can be a breeze or it can be a struggle, and either can be good or bad. Dogs leading can be pleasant or annoying; a leading human can guide the dog (good) or cruelly subdue her (bad). As it takes shape, shapes and re-shapes the pack, the walk must negotiate attachments and hold in the balance all of these valences and qualifications. It is a momentous and consequential event.
The walk, then, is an achievement that is crafted through attachments but at the same time forges them. The leash/lead is not only a tether – attachment, materialized – or a link that associates human and dogs, but, in addition, an object through which new and shifting subjectivities come into effect. While through this tether attachment is practiced and formed, over time, in collaboration and resistance, and with agencies distributed among human, dogs and material object, such attachment is never stable, always shifting, and renegotiated through the presence of the material tie.
How do things hold together? De Laet suggests that togetherness gels by attending to one another’s presence, that such togetherness is not always smooth, and that it requires continuous work. It needs to be done again and again, at each walk, at each visit, at each interaction, at each moment that one of the constituents takes the lead. In the intricacies of going on a walk, agency and control diffuse among actors; words, leash/lead, human and dogs at work craft fidelity to the practice of being a pack. If attachment may be framed as an emergence or refinement of sensibilities in the practices of the mutual, shared, but diverging connections between the dogs and their human – all, arguably, irremediable amateurs in and of each other’s worlds

– the sensibilities that shape themselves are indeed the product and the conditions of the intense focus on living together that living together
What emerges here is a sensibility that attends to the work of keeping materiality and relationship in connection with each other. And in this paradoxical complex of the material and the relational, a moment of wonder presents itself: How, in shifting worlds and environments, with conflicting stakes and interests, do ‘things’ ‘hold’ ‘together’? Rather than taking for granted the stability of worlds and words and things, this wonder orients us towards querying the mechanisms that make (for) coherence, stability and boundedness – however fleeting or fragile the resulting imbroglios may be.
Attaching to guts: Refiguring agency
In Gomart and Hennion’s (1999) sociology of attachments, attachment is framed as a ‘mode of doing’. Exploring the practices of music amateurs and drug users, Gomart and Hennion argue that in the day-to-day engagements with their habits, practitioners subject themselves to what objects (music, instruments, drugs, technique) do to and with them. Meanwhile, in a recursive move, their activities
In similar fashion, Struhkamp et al. (2004) complicate agency in medical practice. Suffering, normally framed as a passive subjection, emerges here as actively and collectively shaped by participants in medical rehabilitation practices. Picking up the Dutch term
Such sensibilities are at work in Vogel’s (2018) inquiry into care practices to do with obesity prevention and treatment. At first sight, the idea of obesity surgery, a set of procedures in which the digestive system is rearranged to achieve reduced nutrient uptake and thus ensure weight loss, might suggest that the surgeon takes over the management of obesity, intervening from the outside onto a passive patient. A closer look at the attachments, practices and normativities at play in one obesity clinic in the Netherlands leads Vogel to argue that people diagnosed as ‘morbidly obese’ actually take on the difficult task of becoming ‘active subjects through submission and (re-)attachment and by arranging support’ (Vogel, 2018: 510).
Obesity surgery – which doctors currently consider the only path to long-lasting substantial weight loss – affords a mode of embodiment that brings patient’s cravings in line with each other, by ‘anchoring’ the will in the body’s anatomy. While the procedure thus holds great promise for patients who have struggled with what some of them have been used to calling ‘their’ obesity, often for quite some time, it is disruptive, too. Intestinal and digestive problems, disordered eating, addiction and malnutrition are not uncommon in the wake of surgical intervention. Clinicians further warn that without a change in lifestyle, the weight loss for which the patient goes to such great length might not last. In the clinic of Vogel’s fieldwork an ‘empowerment lifestyle program’ helps patients engage in healthy activities, manage complications, and deal with the emotional and social consequences of bodily change. For as the surgically altered ‘stomach’ may complicate ingrained practices of self-care through eating, patients must learn to anticipate how it may interfere with social eating patterns and food preferences. Such getting in sync with the body ‘emerges as a matter of aligning, adjusting, attending, organizing and letting go. One change invites another, and in the process, patients do not only
As patients intervene in their own anatomy, they do not do so all by themselves. Agency comes to closely align with support and submission, as patients actively rely on others to craft forceful changes on themselves. Rather than
Although the sites of her fieldwork are clearly marked by strong medical, aesthetic and gendered norms around a good body, good food and good behaviour, Vogel hesitates to analyse her informants’ efforts as evidence of how, struggling to adhere to norms handed down to them, they simply ‘internalize’ these norms. Instead, she highlights how patients are embroiled in a constant effort to attach, and to attach well. Through the work of getting in synch with the body, ‘good’ and ‘bad’ attachments present themselves, ‘both within the skin and outside of it’ (Vogel, 2018: 519). With the help of clinicians, patients pragmatically sort these attachments – even if (and exactly because!) through this sorting, they completely transform. Thinking with attachments, then, affords prominence to practices of reflexivity: A constant testing, assessing, calibrating appreciation is at the heart of participants’ engagement with their environment. It is central, too, in the practice of theorizing these practices: By articulating the normativities at play and the tensions between them, scholars contribute to shaping the fragile, situated ideal of ‘good care’ (Mol et al., 2010). Studies of care practices and other socio-technical entanglements may refuse to judge but nevertheless are committed to probing ways to live well with/in attachments. That commitment places norms inside, rather than outside, the work of science, technology and care; it prompts the question not only of how norms govern actions but, also and more importantly, how they are crafted as knowledge, practices and techniques are made.
Dementia matters: Sense, sensitivity, sensibility
Although predicated on the ability to be affected, attachments should not be confused with affects. Our concern here is not with attachment as ‘lasting psychological connectedness between human beings’ (Bowlby, 1969: 194) – a psychological phenomenon that inscribes love and affection as basic developmental needs.
10
Understood in psychology as an (inter-)personal dynamic that operates ‘on’ or ‘in’ relationships, its paradigmatic case is the apparent connection between parent and child. In contrast, we do not offer a ‘theory of attachment’ here, nor do we frame attachment as psychological force. Rather, as we discuss the work of attachment in techno-social configurations, the term is a heuristic, a theoretical tool. The body of work in STS that brings attachments into focus, always rooted in specific case studies, invites telling stories about knowing, doing, caring and crafting that probe the processes, the bodies, the objects, the subjects and the practices that,
Neither should attachment be confused with an innate sensitivity. The ability to ‘sense’ is not a faculty one ‘has’; sensing is rather a practice from which the senses develop. Rather than an individual and innate capability, sensing emerges as the crafted effect of the relations between worlds and their bodies. Describing her efforts to become an expert
The senses are thus pertinent to – as they are subject to – the process of becoming-in-relating. With that established, curiosity arises about how sensitive worlds are made. If one is an ‘excellent nose’, a ‘discerning taster’, an ‘average smeller’, one is becoming so in a complex set of engagements. No longer is taste a natural faculty, sensitivity a ‘given’ characteristic of a stable body or a feature determined by the class, schooling and educative sophistication into which that body is socialized. Taste does not reside in the qualities of either object or subject – it is a product of the activity in which subject and object become ‘together’: collaboratively, in tension or in collusion, simultaneously involved. Sensibility and sensitivity develop; they ‘are’ not, but are made (Mann, 2015, 2018). And such moving and making requires effective and affective work.
Taking this very starting point, in her ethnography of Dutch nursing homes for people with dementia, Driessen (2018) brings out the collective character of crafting sense and sensitivities – at once. Public imaginary of dementia stages the condition as a neurological pathology that inevitably leads to a passive life with no hope of joy. Indeed, portrayals of nursing homes report on elderly residents ‘dozing’, placidly watching television; suggesting a causal, necessary and inescapable connection between dementia and apathy. Thinking with attachments allows a different version of dementia; it counters the idea that pathology blocks affect and that – thus! – in the absence of pathology, affect is a given.
Taking up Gomart and Hennion’s (1999) claim that ‘active work must be done in order to be moved’, Driessen narrates care practitioners’ efforts for the nursing home’s residents’ affects. Care emerges as the conduit that enables them to take pleasure in dancing, bathing, music and movement. Everyday tasks emphasize such pleasures: In one field site a care worker and a physical therapist organize dance events, in another, staff reshuffles tasks and schedules to repurpose an underused bathroom to allow for one-on-one moments in which residents receive personal, spa-like attention. In providing bodily care through unconventional elements such as music, drinks and togetherness, care professionals bring about attachments and so, Driessen (2018) argues, ‘craft conditions for pleasure’ (p. 28).
Importantly, she notes, enjoyment cannot be forced. Attachments to these new elements of care do not always form, and residents are not mere recipients. For as they interact with these things that may or may not afford pleasure, a play of invitation and acceptance affords staff and residents a chance to develop sensitivities – to one another and to the things around them. And in this play, rather than singularly catering to the sensory capacities that ‘still are’, more fully sensing residents emerge: ‘Music entices the body to move. The care professional or volunteer extends a hand and the stability for a dance … the resident accepts the hand, steps onto the dance floor, moves along and leads’ (Driessen, 2018: 29). Invited into such attachments, residents who accept can come to feel enjoyment – and, surprisingly, so may others. For when residents enjoy themselves, bystanders do so as well. ‘If the care workers let themselves be affected, they too emerge as joyful subjects’ (Driessen, 2018: 29). While affect emerges here from the work done for people with dementia, the case raises a more general point, that speaks to those with and without cognitive difficulties alike: Sense and sensitivity are not given and are therefore not irrevocably lost; they do not come in predictable form but rather come about through collective investments in attachments.
As ‘[a]ppreciations may be missed by those not receptive to them’ (Driessen, 2018: 34), thinking with attachments – or so we suggest – has consequences for the practice of knowledge production in STS itself. Calling on ethnographers to learn to be sensitive, to extend an invitation to their interlocutors to enact their subjectivity and, so, to enable unforeseen potentialities, Driessen (2018) suggests that making responsive and responsible knowledge indeed demands from the researcher a willingness and capacity to be moved (pp. 34–35). But – and this is what is distinctive about this approach – ‘attachments do not
Conclusion
We have described attachment as a generative sensibility that is specific to, and constitutive of, subjects in practice. Such practice involves materials, bodies, gestures, collectives, built environments, situations and locales. Thinking with attachments, as we have shown, allows the articulation of the social as more than an
We propose to think
We share this commitment with others in feminist STS who have attended to care in science, technology and beyond. If scholarly work is not neutral, but normative and engaged, how should we understand this normativity? Today, care and affect are not only considered as empirical topics of study, but also, in a reflexive move, as an invitation to question the politics of our own knowledge production (de la Bellacasa, 2017). Following Felski’s (2015) exploration of the limits of distant, sceptical critique, we can now understand being political or ‘normative’ in our work differently. Taking seriously de la Bellacasa’s (2011) call ‘to exhibit the concerns that attach and hold together matters of fact is to enrich and affirm their reality by adding further articulations’ we are interested in
All too often feminist ethical-political commitments are themselves recast in affective terms: Some scholars claim that when engaging the worlds we study, ‘we cannot but care’ (Martin et al., 2015). We argue, however, it is not just important to recognize that norms and values shape all kinds of inquiry. Our proposal to think with attachments underscores that our very practices of inquiry shape our principles, beliefs and passions, too. What is ‘right’ and ‘wrong’ is not given but made, emerging through our engagements with a situated field. In other words, taking attachments seriously, we must acknowledge that entities, including the researcher,
Thinking with attachments means attending to what Pols (2015) calls ‘intranormativity’: To a careful and mindful way of attending to local, situated, distributed and emerging goods and bads. So, thinking the leash with attachments does not draw us immediately into the hierarchical politics of animal husbandry and power, but takes up such concerns in order to, instead, open up a sensitivity to the social and material intricacies of living together (well). The case of obesity surgery, when thought with attachments, does not call out directly the (gendered) establishment of body norms and forms of bodily control, but invites a conversation of what constitutes ‘good care’ in the face of the conflicting set of physical, psychological and social challenges and norms that coalesce around obesity. Thinking dementia with attachments, finally, reimagines dementia as more than just a neurological condition characterized by loss. Instead, it emphasizes how specific relations surface response-ably in the lives of people with dementia and those who care for them, generating senses and sensitivities.
These situated analyses reveal that where there are bads, there are also goods; where things hold, they also crumble. ‘Attachments’, then, account for how things stick; detachments, for how they come apart. Attending to
