Diffracting a research project in a UK primary school, this paper concerns feminist materialist orientations to odd-ness as a relational, distributed, and affective form of "thinking-feeling". It suggests that attuning to affect as it moves through a context resistant to disruption, involves becoming "bad researchers"; bad for composing an unruly research problem, for embracing a transgressive methodology, and for writing in willfully inconclusive ways. It comments too on the dangers of embracing badness as an identity if used to conceal rather than acknowledge ongoing inequalities between researchers and children and between privileged researchers and others routinely marginalised.
