The debate about the definition of Latinidad as a social identity has fluctuated between accounts that put it closer to ethnicity or closer to race. We present and defend the claim that the multiplicity of features and experiences of Latinxs in the United States is best accounted for by placing Latinidad in a different theoretical space. We draw from the ecological psychology and enactive literature on affordances to argue that Latinidad can be better understood as a social identity affordance: a (...) multifaceted landscape of possibilities for interaction, to do and to be done unto. We then focus on four areas that are part of the objective factors that have come to constitute Latinidad and which provide reasons to shy away from both race and ethnicity: the facts of mestizaje and hybridization, a vexed relation to the land, the political horizons and histories of this population, and the multiplicity of sensory-based cultural practices of Latinxs. It is precisely the many and deep variations across Latinxs that make social affordances an apt way to conceptualize a social identity whose reality is asserted pragmatically in many aspects of social life in the U.S. (shrink)
