Algorithmically driven online dating platforms today promise the ability to sort through relevant data and identify one’s ideal amorous matches effectively. Yet the appeal of technological and scientific solutions to the messy problem of finding partners is hardly new.

Taking matching as an “applied science of social harmony,” the (...) authors argue that concern over more reliable techniques for determining the suitability of partners has formed an essential part of both the maintenance of social order and the shaping of subjectivities, enabling discourses of informed choice and the rational management of the passions, while also reinforcing and subverting structures of age, gender, race, and sexuality.
