The epistemic harms of direct-to-consumer genetic tests

In this paper, I provide an epistemic evaluation of the harms that result from the widespread marketing of direct-to-consumer (DTC) genetic tests. While genetic tests are a valuable accessory diagnostic tool when ordered by a medical practitioner, there are different implications when they are sold directly to consumers. I aim to show that there are both epistemic and non-epistemic harms associated with the widespread commoditization of DTC genetic tests. I argue that the epistemic harms produced by DTC genetic tests have been disregarded in discussions on the topic. Drawing on the notion of contributory epistemic injustices, I highlight two pertinent epistemic harms: (1) a failure to uptake an individual’s articulations about their identity and (2) the presiding reductionist framework dismisses useful hermeneutical resources. I then propose ways to mitigate these harms.
