If you could erase the worst memory of your life, would you? Scientists are working on a pill for that - #technoskeptic #dystopia

"The 60 souls that signed on for Dr. Alain Brunet’s memory manipulation study were united by something they would rather not remember. The trauma of betrayal.

Over four to six sessions, volunteers read aloud from a typed script they had composed themselves — a first-person account of their breakup, with as many emotional details as possible — while under the influence of propranolol, a common and inexpensive blood pressure pill. The idea was to purposely reactivate the memory and bring the experience and the stinging emotions it aroused to life again. “How did you feel about that?” they were asked. How do you feel right now? And, most importantly: Has your memory changed since last week?

But the idea that memories can be edited, softened or dialled down, is more than a little discomfiting to some, and not just for what it means for eyewitness testimony. “We’re not reliable narrators when it comes to some details, and sometimes even entire scenarios,” Ramirez says. More profoundly, without good and bad memories it’s hard to imagine how we would know how to behave, says Dr. Judy Illes, professor of neurology and Canada Research Chair in neuroethics at the University of British Columbia.

Learning doesn’t occur without memory. How do we learn from a bad relationship, if we can’t remember it? “And so now, if we pre-select what memories stick and don’t stick, it almost starts to be like the eugenics of memory,” Illes says. “We ought to think carefully about that.”"
