 Our increasing reliance on novel forms of external memory, may have surprising ethical ramifications. The default for human memory is to forget, and most of the information that we encounter never makes its way into long-term memory. The default for computer memory, in contrast, is to remember, and researchers are beginning to explore the ethical implications of moving from a state of affairs in which forgetting is the norm, in the sense that one’s words and deeds would in general leave few permanent traces, to one in which remembering is the norm, in the sense that many of our words and deeds leave behind more or less permanent digital traces (Mayer-Schönberger 2009). When remembering is the norm, people may, in particular, be deprived of any opportunity for a fresh start after engaging in inappropriate behaviours, leading some to argue for a right to be forgotten (Ghezzi, Pereira, &amp; Vesnic-Alujevic 2014; J. Rosen 2012). From a legal and technological point of view, such a right is likely to be difficult to implement. From a moral point of view, a right to be forgotten may imply a duty to forget, and it is unclear whether we can plausibly be held to have such a duty (Matheson 2013).
