Can communication Brain-Computer Interfaces read minds?

Abstract

Abstract: Recent developments in the domain of communication Brain-Computer Interface (BCI) technology have raised questions about the ability for communication BCIs to read minds. How those questions are answered depends on how we theorize the mind and mindreading in the first place. Thus, in this paper, I ask (1) what does it mean to read minds? (2) can a communication BCI do this? (3) what does this mean for potential users of this technology? and (4) what is at stake morally in light of this? I show that current answers to these questions are conceptually unclear and committed to a Cartesian picture of the mind and its relation to the brain, questionably informing how debates about BCIs as mindreading devices are framed. I offer an alternative perspective on these questions by turning to an enactive perspective on mindedness. I argue that this perspective can offer conceptual as well as ethical clarification about what is at stake in the domain of communication BCIs. From this perspective, the concerns raised about BCIs as mindreading machines are demystified. Instead, concerns are raised about BCIs as enabling users to flourish as authentic communicators.
