Feminism often begins with intensity: you are aroused by what you come up against. You register something in the sharpness of an impression. Something can be sharp without it being clear what the point is… Things don't seem right. (Ahmed 2017: 22) "It didn't really gel", an established emotion scholar sympathetic to feminist scholarship said after we had both taken part in a workshop on emotion 1 research in International Relations (IR). I agreed. Four feminist scholars (out of 19) had been invited. The invitation meant recognition of feminist work as valuable when it comes to research on emotions, affect, passions and sensibilities in IR. And yet, my impression during the workshop was that it was as if we were speaking different languages. More generally, what was at stake was different understandings of 'the political' and, as a result, how to study the politics of emotion in IR. But more specifically, I began to think about how the active disinterest in feminist knowledge in IR more broadly is also often affectively felt. In Living a Feminist Life, Sara Ahmed discusses how sensation matters because "you are left with an impression that is not clear or distinct" (2017: 22). She goes on to argue, "a gut feeling has its own intelligence. A feminist gut might sense something is amiss. You have to get closer to the feeling" (2017: 27). My overall impression that something about the interactions during the workshop did not make sense was both an affective and emotional experience: following Ahmed, I wanted to get 'closer to the feeling'. To me (and I am sure other feminists in the room), the impression that our discussions during the workshop "didn't gel" was no surprise, perhaps even expected. But, my (non-feminist) colleague's reflection stayed with me because it touched on the much bigger issue of how feminist knowledge on global politics is often ignored more generally in IR. My experience at this workshop fed into previous experiences and my sense of irritation grew. It grew into this paper. Following Sianne Ngai's (2005) exploration of the critical productivity of negative affective senses (e.g. envy, shame, disgust and paranoia), I want to use my growing sense of irritation to think carefully about how (and why) "It didn't really gel." Feminist scholars have successfully drawn attention to the fact that gender matters in global politics. It is a good thing that it no longer make sense to exclude feminists from various academic spaces-this is not always the case, but the landscape is definitely changing. It is a good thing that many now realise that feminist research matters. And yet, after decades of 'including' feminist theory in IR, feminist knowledge remains marginalised. This is not a new observation (Tickner 1997; Steans 2003), but what concerns me is the continuing presence and force of this marginalization, and the way it makes itself felt at the levels of affect and emotion. Feminist scholars are increasingly invited into academic spaces, while feminist knowledge is, still, too often ignored. Non-femi...
