“…Tracking entails relieving oneself of the burden of making the right choices in pursuing 'optimization', by delegating decisions related to nutrition and sports activities, for example, to the calculative capacities of tracking technologies, which in turn may subject the user to surveillance (Sanders, 2017) or relegate them to a less reflexive state (Schüll, 2016). Research on everyday experiences of self-tracking provides nuance to these arguments of responsibilization and delegation, recognizing a more agentic and wilful 'ethico-psychological' (Pols et al, 2019) subjectivity, which is activated by the personalized, experimental and embodied ways in which humans use their devices and produce, interpret, repair and communicate with data (Gorm & Shklovski, 2019;Lomborg et al, 2018;Mopas & Huybregts, 2020;Pink et al, 2017Pink et al, , 2018Weiner et al, 2020;Will et al, 2020). These studies urge us to move beyond the argument that an algorithm or a technology has definitive agential capacities, or that responsibility for one's pursuit of health and care is dumped upon the technology; allowing for a distributive conceptualization of responsibility (Latour, 2005) and care (Mol, 2008), both emerging relationally, within infrastructures or arrangements consisting of technologies and human actors (Barad, 2007;Lupton, 2019;Schwennesen, 2019;Will et al, 2020).…”
