POTs: Protective Optimization Technologies

Algorithmic fairness aims to address the economic, moral, social, and political impact that digital systems have on populations through solutions that can be applied by service providers. Fairness frameworks do so, in part, by mapping these problems to a narrow definition and assuming the service providers can be trusted to deploy countermeasures. Not surprisingly, these decisions limit fairness frameworks' ability to capture a variety of harms caused by systems. We characterize fairness limitations using concepts from requirements engineering and from social sciences. We show that the focus on algorithms' inputs and outputs misses harms that arise from systems interacting with the world; that the focus on bias and discrimination omits broader harms on populations and their environments; and that relying on service providers excludes scenarios where they are not cooperative or intentionally adversarial. We propose Protective Optimization Technologies (POTs). POTs provide means for affected parties to address the negative impacts of systems in the environment, expanding avenues for political contestation. POTs intervene from outside the system, do not require service providers to cooperate, and can serve to correct, shift, or expose harms that systems impose on populations and their environments. We illustrate the potential and limitations of POTs in two case studies: countering road congestion caused by traffic-beating applications, and recalibrating credit scoring for loan applicants.Comment: Appears in Conference on Fairness, Accountability, and Transparency (FAT* 2020).

Black placemaking: Celebration, play, and poetry

Using Chicago as our case, this article puts forth a notion of black placemaking that privileges the creative, celebratory, playful, pleasurable, and poetic experiences of being black and being around other black people in the city. Black placemaking refers to the ways that urban black Americans create sites of endurance, belonging, and resistance through social interaction. Our framework offers a corrective to existing accounts that depict urban blacks as bounded, plagued by violence, victims and perpetrators, unproductive, and isolated from one another and the city writ large. While ignoring neither the external assaults on black spaces nor the internal dangers that can make everyday life difficult, we highlight how black people make places in spite of those realities. Our four cases – the black digital commons, black public housing reunions, black lesbian and gay nightlife, and black Little League baseball -elucidate the matter of black lives across genders, sexualities, ages, classes, and politics
