Public attitudes on the ethics of deceptively planting false memories to motivate healthy behavior
Researchers have proposed that planting false memories could have positive behavioral consequences. The idea of deceptively planting “beneficial” false memories outside of the laboratory raises important ethical questions, but how might the general public appraise this moral dilemma? In two studies, participants from the USA and UK read about a fictional “false-memory therapy” that led people to adopt healthy behaviors. Participants then reported their attitudes toward the acceptability of this therapy, via scale-rating (both studies) and open-text (Study 2) responses. The data revealed highly divergent responses to this contentious issue, ranging from abject horror to unqualified enthusiasm. Moreover, the responses shed light on conditions that participants believed would make the therapy less or more ethical. Whether or not deceptively planting memories outside the lab could ever be justifiable, these studies add valuable evidence to scientific and societal debates on neuroethics, whose relevance to memory science is increasingly acute

Sleep deprivation and false confessions.
False confession is a major contributor to the problem of wrongful convictions in the United States. Here, we provide direct evidence linking sleep deprivation and false confessions. In a procedure adapted from Kassin and Kiechel [(1996) Psychol Sci 7(3):125-128], participants completed computer tasks across multiple sessions and repeatedly received warnings that pressing the "Escape" key on their keyboard would cause the loss of study data. In their final session, participants either slept all night in laboratory bedrooms or remained awake all night. In the morning, all participants were asked to sign a statement, which summarized their activities in the laboratory and falsely alleged that they pressed the Escape key during an earlier session. After a single request, the odds of signing were 4.5 times higher for the sleep-deprived participants than for the rested participants. These findings have important implications and highlight the need for further research on factors affecting true and false confessions

Convicting with confidence? Why we should not over-rely on eyewitness confidence.
Eyewitness memory researchers have recently devoted considerable attention to eyewitness confidence. While there is strong consensus that courtroom confidence is problematic, we now recognise that an eyewitness's initial confidence in their first identification - in certain contexts - can be of value. A few psychological scientists, however, have confidently, but erroneously claimed that in real-world cases, eyewitness initial confidence is the most important indicator of eyewitness accuracy, trumping all other factors that might exist in a case. This claim accompanies an exaggeration of the role of eyewitnesses' "initial confidence" in the DNA exoneration cases. Still worse, overstated claims about the confidence-accuracy relationship, and eyewitness memory, have reached our top scientific journals, news articles, and criminal cases. To set the record straight, we review what we actually know and do not know about the "initial confidence" of eyewitnesses in the DNA exoneration cases. Further reasons for skepticism about the value of the confidence-accuracy relationship in real-world cases come from new analyses of a separate database, the National Registry of Exonerations. Finally, we review new research that reveals numerous conditions wherein eyewitnesses with high initial confidence end up being wrong
