Propranolol is a beta blocker that is sometimes used in the treatment of hypertension and migraines. The Sixty Minutes segment The Memory Pill looked at its use for treating post-traumatic stress syndrome. Apparently, one of its effects is to lessen the intensity and immediacy of traumatic memories. Various patients were interviewed, all of whom showed astounding improvement after years– even decades– of suffering from severe PTSD following car accidents, physical debilitation, and rape.

Although the results are more than promising– there seem to be few side-effects– research in the US was effectively shut down after a White House bioethics report questioned the ethics of “altering memory.” Research continues in Canada, though, and it looks like the U.S. Military is going to start funding that research…

Critics worry about the effects of manipulating memory. Learning to deal with traumatic events is part of psychological growth. What happens if we short-circuit that process? How will it effect not just what we learn, but how we handle similar situations in the future? What role does memory– even traumatic memory– play in the formation and effectiveness of conscience? Could this become a drug that people take to forget their bad behavior at a party, that criminals take to make them more effective in pursuing their nefarious tasks, or that the military force feeds soldiers to make them better able to “kill, kill, kill”?

These are fascinating and interesting questions, but ultimately they are irrelevant. This cat is out of the bag– both in substance and peoples’ desires– and one can only imagine the kinds of memory manipulation we’ll see in the next few decades: memory erasers, intensifiers, enhancers. It’s the road humanity is on, love it or leave it (like you have a choice).
