Memory modification technologies (MMTs)—interventions within the memory affecting its functions and contents in specific ways—raise great therapeutic hopes but also great fears. Ethicists have expressed concerns that developing and using MMTs may endanger the very fabric of who we are—our personal identity. This threat has been mainly considered in relation to two interrelated concerns: truthfulness and narrative self‐constitution. In this article, we propose that although this perspective brings up important matters concerning the potential aftermaths of MMT utilization, it fails to (...) tell the whole story. We suggest that capturing more tangible potential consequences of MMT use, namely, its psychological ramifications is crucial both in ethical considerations and in making decisions regarding the permissibility of such interventions. To this end, we first examine what current MMTs are capable of and what are the prospects of emerging MMTs. Subsequently, we outline the relationship between memory and personal identity; specifically, we indicate that concepts of self‐defining memories and narrative identity are crucial to considering how MMTs may influence one's psychological functioning. On this basis, we analyze potential consequences of narrative disruption that may be the result of the use of MMTs; more precisely, we consider its potential effects on mental health, well‐being, and personal agency, and outline the ethical dilemmas that decision‐makers face in this context. We conclude by considering the broader cultural context that may have influence on policymaking regarding permissibility of memory modification interventions. (shrink)

Moral bioenhancement is the attempt to improve human behavioral dispositions, especially in relation to the great ethical challenges of our age. To this end, scientists have hypothesised new molecules or even permanent changes in the genetic makeup to achieve such moral bioenhancement. The philosophical debate has focused on the permissibility and desirability of that enhancement and the possibility of making it mandatory, given the positive result that would follow. However, there might be another way to enhance the overall moral behavior (...) of us humans, namely that of targeting people with lower propensity to trust and altruism. Based on the theory of attachment, people who have a pattern of insecure attachment are less inclined to prosocial behavior. We know that these people are influenced by negative childhood memories: this negative emotional component may be erased or reduced by the administration of propranolol when the bad memory is reactivated, thereby improving prosocial skills. It could be objected that memory-editing might be a threat for the person’s identity and authenticity. However, if the notion of rigid identity is replaced by that of extended identity, this objection loses validity. If identity is understood as something that changes over time, moral bioenhancement through memory-editing seems indeed legitimate and even desirable. (shrink)
