People who don’t forget can still be tricked with false memories

Despite being able to remember minute details from every moment of their lives, the ability to never forget has other costs for some people.

“Time is the thief of memory,” wrote Stephen King in one of his many books. For some people, however, that is not true. They are gifted with what scientists call highly superior autobiographical memory (HSAM), which means they can remember in vivid detail every day of their life going back to childhood. But new research shows that even these special people are susceptible to forming false memories, sometimes more than normal people.

The first study of a person, later identified to be Jill Price, with this special ability was published as recently as 2006. Since then the database of HSAM individuals in the US has grown to about 30 people. It includes people like Bob Petrella, who can recall the date he met every one of his friends and acquaintances. Or Brad Williams, who can remember both what he did on any day and what significant world events occurred.

James McGaugh at the University of California Irvine was the author of the 2006 study, and for the past seven years he has been working to understand what makes HSAM individuals so special. A 2012 study showed, for instance, that HSAM individuals have different brain structures. They posses more white matter in areas linked to autobiographical memory. But because there are so few of them “we still don’t know enough to be able to draw robust conclusions”, says Martin Conway, a cognitive psychologist at City University London.

Knowing how HSAM people form memories would be a great leap in our understanding. With graduate student Lawrence Patihis, McGaugh set out to fill that gap. One way to do that would be to test if HSAM individuals are susceptible to false memories. After all, memories are easy to distort. It happens to everyone: the young, the old, the intelligent and the dumb. Now, in a study just published in the Proceedings of the National Academy of Sciences, Patihis finds that HSAM individuals too can be tricked to possess false memories.

Not so perfect
For the study, Patihis recruited 20 out of the 30 known HSAM individuals in the US. They were matched, by sex and age, with 38 people with normal memory. All of the participants were then given three tests.

In the first test, each participant was shown a series of words that were all supposed to be connected to a “lure word”. So if the lure word was “lamp” then they will be shown words like light, table, shade and stand, but not the word lamp. After they have seen the list, they are asked if they saw the word lamp. People with normal memories got the answer wrong seven out of ten times. HSAM individuals too got it wrong just as much.

The second test was more elaborate. It showed a slideshow of photos depicting a crime. After 40 minutes, they were then shown words describing the crime with misinformation sprinkled in them. Then 20 minutes later they were tested to see how many people believed the misinformation to be true. This time HSAM individuals did worse than normal people. They were 73 percent more prone to false memories. “Maybe HSAM individuals form richer memories through absorption of more information and that is why they are also more susceptible to false ones too,” says Patihis.

Perhaps it is easy to manipulate recent memories. So in the third test Patihis looked to test long-term memory. All participants were asked to recall the September 11 terrorist attacks. They were then given irrelevant facts about that event, one of which was not true (someone captured the footage of United 93 in Pennsylvania). After 15 minutes, all participants were then asked whether they had see such a footage. Like the first test, normal people and HSAM individuals performed almost equally badly on this test.

“This shows that maybe people with superior memories form them just like normal people. Thus, in the process, they are also prone to making the same mistakes,” says Patihis. Equally, they may use a different process of forming superior memories, but one that has same problems as that of the normal process.

There is still contention among experts whether HSAM individuals are “special”. K Anders Ericsson of Florida State University says, "our work has pretty much concluded that differences in memory don’t seem to be the result of innate differences, but more the kinds of skills that are developed." To which McGaugh says, “you’d have to assume that every day they rehearse it ... The probability of these explanations dwindles as you look at the evidence."

Price had admitted that remembering everything meant bad memories were always around to trouble her. It led researchers to believe that such superior memory may come at a cognitive cost of lost abilities, or less happier lives. But research since has shown that not to be the case. HSAM individuals tend to have similar lives to normal people. With the latest study, McGaugh has shown one more task where HSAM individuals are normal. They too may be made to believe that as a kid they were lost in a shopping mall, even if that isn’t true.

It’s 2016, so why do printers still suck?

Hewlett Packard recently prevented third-party cartridges from working in their printers, but this is just the latest chapter of home printing's dark and twisted history. 

In order to initiate their children into adulthood, the Sateré-Mawé tribe in the Brazilian Amazon weave stinging ants into gloves and ask teenage boys to wear them for a full ten minutes. The British have a similar rite of passage, though men, women, and children alike partake. At one point in their short, brutal little lives, every citizen must weep at the foot of a printer at 2am, alternatively stroking and swearing at it, before falling into a heap and repeating “But there is no paper jam” 21 times.

There are none alive that have escaped this fate, such is the unending crapness of the modern home printer. And against all odds, today printers have hit the news for becoming even worse, as a Hewlett Packard update means their machines now reject non-branded, third-party ink cartridges. Their printers now only work with the company’s own, more expensive ink.

Although it’s surprising that printers have become worse, we’re already very used to them not getting any better. The first personal printers were unleashed in 1981 and they seemingly received the same treatment as the humble umbrella: people looked at them and said, “What? No, this? No way this can be improved.”

It’s not true, of course, that printing technology has stagnated over the last 35 years. But in a world where we can 3D print clitorises, why can’t we reliably get our tax returns, Year 9 History projects, and insurance contracts from our screens onto an A4 piece of paper in less than two hours?

It’s more to do with business than it is technology. Inkjet printers are often sold at a loss, as many companies decide instead to make their money by selling ink cartridges (hence HP’s latest update). This is known as a “razor and blades” business model, whereby the initial item is sold at a low price in order to increase sales of a complementary good. It explains why your ink is so expensive, why it runs out so quickly, and the most common complaint of all: why your cyan cartridge has to be full in order to print in black and white.

But technology is complicit in the crime. HP’s new update utilises the chips on ink cartridges to tell whether a refill is one of their own, and have also previously been used to region-block cartridges so they can’t be sold on in other countries. Those little chips are also the thing that tells the printer when your ink is empty. Very good. Fine. Except in 2008, PC World found that some printers will claim the cartridges are empty when they are actually nearly half-full.

Back to business. Because this profit models means companies sell printers for so little, quality inevitably suffers. If they’re not selling them for much, companies will naturally try to keep the costs of making their printers down, and this is the reason for your “Load paper in tray two”s, your “Paper jam”s and your “Would you like to cancel this print job? Nope, sorry, too late, here are 100 copies.”

So why are printers bad at networking? This isn’t a set up to a lame joke (unless the joke is, of course, your life as you try to get your wireless printer and your PC to connect). There doesn’t seem to be a definitive answer to this, other than the fact that Bluetooth is still fairly patchy anyway. Some errors, just as you suspected, happen for no bloody damn good bloody reason at all.

On a bigger scale, the printers in your office are difficult because they work harder than you ever have. It’s a stressful job, for sure, and this naturally comes with errors and jams. The reason they are so hard to fix after the inevitable, however, again comes back to capitalism. Because printers don’t have a universal design, most companies will protect theirs, meaning you can’t know the specifics in order to fix a device yourself. This way, they also make money by sending out their own personal technicians.

Thankfully, although every personal printer you’ve ever bought seems to be on collaborative quest to drive you to madness, there is an easy fix. Buy a laser printer instead. Though the device and the replacement toner cartridges are more expensive, in the long-run you’ll most likely save money. In the meantime, there's only one solution: PC load letter.
