Debus focused on how people have to exert efforts to ensure that they remember a particular event, thinking, for example, What was it that I did last Sunday? Both Michaelian and Debus aimed to reconcile the activity involved in episodic memory with this memory producing knowledge. Michaelian argued that the reconstruction involved in remembering produces representations that are true to events as they occurred (even if they do not exactly replicate the experiences that people had of the events), so can produce accurate memories, and knowledge, of those events. Debus argued that as long as an active intervention does not interfere with the believer meeting epistemic norms, those that lead to accurate beliefs, the intervention does not prevent the formation of the memory leading to knowledge.
When someone has an observer memory, they remember an event, in which they were present, from the perspective of an observer and they feature in the memory. Observer memories do not represent the past as it was experienced by the individual, but they can nonetheless accurately reflect the event as it occurred. In such cases, an individual is active in the formation of the memory, they do not simply access a record of the event as it was experienced, but the memory nonetheless contains accurate information about the past so meets the epistemic norm of accuracy. Observer memories therefore illustrate Debus’s and Michaelian’s points: that memories can be accurate although they are the result of the activity of the rememberer.
Jordi Fernandez also discussed the phenomenon of observer memories. Fernandez considered whether the existence of these memories challenged the claim that if one has a full and accurate memory of an event it cannot be that one misidentified the person who featured in the memory as “I”. Observer memories might seem to present a case in which one has a full and accurate memory of an event but one misidentifies the person who features in the memory as oneself, but Fernandez denied this point.
Finally, a number of talks explored how other people determine what we remember. John Sutton described how people in long-term relationships seem to share memories, they can remember events that occurred in the other person’s life when they were not present. Michaelian considered how the way that we remember might be influenced by our need to be able to explain ourselves to others. He suggested that our memories are likely to be accurate because of other people’s epistemic vigilance, i.e. their ability to discern whether we are good sources of information and to keep us in check. Meanwhile, I argued that some memory distortions are the result of memory systems being designed to enable us to work out whether other people are reliable sources of information. Other people indirectly influence what we remember, because our memory systems are designed to ensure that we can maximize the useful information that we can glean from them.
