Biases in AI Systems

A child wearing sunglasses is labeled as a "failure, loser, nonstarter, unsuccessful person." This is just one of the many systemic biases exposed by ImageNet Roulette, an art project that applies labels to user-submitted photos by sourcing its identification system from the original ImageNet database.7 ImageNet, which has been one of the instrumental datasets for advancing AI, has deleted more than half a million images from its "person" category since this instance was reported in late 2019.23 Earlier in 2019, researchers showed how Facebook's ad-serving algorithm for deciding who is shown a given ad exhibits discrimination based on race, gender, and religion of users.1 There have been reports of commercial facial-recognition software (notably Amazon's Rekognition, among others) being biased against darker-skinned women.6,22

These examples provide a glimpse into a rapidly growing body of work that is exposing the bias associated with AI systems, but biased algorithmic systems are not a new phenomenon. As just one example, in 1988, the U.K. Commission for Racial Equality found a British medical school guilty of discrimination because the algorithm used to shortlist interview candidates was biased against women and applicants with non-European names.17
