This paper aims to better understand and account for potential difficulties in empathising with each other in online spaces. I argue that two important differences between online and in-person communication are both to do with what information comes across in equivalent interactions. Firstly, there are ways in which less information comes across in online interactions (both consciously and unconsciously). Secondly, agents have greater control over what information comes across in online interactions. I argue that these differences can cause problems in (...) terms of whether online spaces are as fruitful ground for empathising with each other. This is because the information that gets left out is often what’s important for building up a fuller and more vivid picture of what the other person’s experiences are like, such as identity-markers or vulnerabilities. But despite this, I end on an optimistic note, because we will become more practiced at reading between the lines, as well as adapting and using media more creatively. (shrink)
