The Technologically Enhanced Memory

How will life change if we can’t forget anything?

According to a recent study, memory’s sharpness deteriorates earlier than we presumed: Forty-five is the new mental 60. Fortunately, there are practical ways to enhance mental agility: exercise, healthy diet, sufficient rest, learning new things. Increasingly, technology will play an important role in preserving cognitive function. From the sanctioned war on Alzheimer’s to widespread off-label use of Ritalin, Adderall, and Modafinil, one thing is clear: We’re intent on getting our memory enhancement on.

Ubiquitous information and communication technology is a major player in the memory enhancement game. I’m not alluding to products that target impairments, like the iPhone app for combating dementia. Rather, I mean commonplace software that people use to make recall less taxing, more extensive, or easier to visualize.   

For instance, Wikipedia’s anti-SOPA protest made 162 million users, accustomed to turning to the site for those idle questions that crop up every day, feel absent-minded. Nobody messed with my hippocampus or your prefrontal cortex. Rather, Wikipedia’s actions were jarring because Internet use affects transactive memory, which is “the capacity to remember who knows what.” If we know information is available online, we’re inclined to remember where it can be found, rather than struggle to retain the facts. This evolutionary tendency to off-load taxing aspects of cognition into the environment—natural or built—extends beyond using devices to recall information we’re already familiar with.

This is called “extended cognition,” and it plays a crucial role in a controversial view called the “extended mind” thesis. Advocates argue that data-management technologies, from low-tech pads to high-tech computers, don’t always function as mere memory-prompting tools. Sometimes, they deserve to be understood as parts of our mind.

While controversy doesn’t surround the science of transactive memory, its implications are hotly debated. Philosopher of science Ronald Giere rejects the extended mind view to avoid conceptual and ethical problems. Others express concern about our ability to use technology responsibly. Nicholas Carr, author of “Is Google Making Us Stupid?”, calls research into technology’s effects on transactive memory “disquieting.” In All Things Shining, renowned artificial intelligence critic Hubert Dreyfus and Harvard University’s Sean Kelly depict reliance on GPS navigation as so acidic to skill and meaning that it “flattens out human life.” Historian Edward Tenner suggests “access to electronic memory tends to give us an exaggerated view of our knowledge and skills.” Such ongoing debate signals an important cultural shift, one we’re all struggling to come to terms with.

Until recently, memory problems indicated a deficiency in personal character, a shortage of “ethics or humanity.” This outlook was a sign of the times: Informational scarcity fueled an ethos of individualism. Today, advances in technology and technique enable vast quantities of networked information to be stored and retrieved cheaply, simply, and reliably. Information abundance fuels its own ethos where interdependency and mediation take center stage. Go to a party and brag about your ability to recall contact information. Nobody will toast your commitment to swimming against the tide of memory depletion. Instead, folks will tell you and your antiquated sensibilities to get a life and a smartphone.

Transhumanists like George Dvorsky are holding out for perfect memories, or total recall: “Count me in for when perfect memory finally becomes medically possible,” he has written. Maybe I’m old-fashioned, but this sounds terrible. The ability to forget allows us to forgive (“time heals all wounds”) as the pain of memories fades. It also allows us to make difficult, but important life-altering decisions. Ethicist Justin Weinberg suggests perfect recall of the pain of childbirth and the tortures of new-parent sleep deprivation could impact reproduction. More than a century ago, Nietzsche speculated that active forgetting is the key to living a life unencumbered by resentment. Today, scientists concur. Memory is seen as a creative “means for endlessly rewriting the self.”

Luckily for me (but not Dvorsky), perfect recollection isn’t close to being feasible. Drugs and surgery aren’t there yet, nor are digital means. Michigan State’s Lawrence Busch argues that data storage technology is more advanced than data-cataloging tools:

Large-scale data sets commonly stored on computers present many of the same problems as memory-enhancing technologies. First, data often are drawn from highly biased samples containing numerous errors; a few outliers may skew interpretation of the entire data set. Second, data-mining programs often don’t live up to the hype. They fail to detect subtle differences and identify the proper features of salience.

Perhaps, though, incremental advances in “key phrase search capabilities” are all it takes to dramatically enhance our recall powers.
