This is your brain on a smartphone
Clifford Nass passed away in 2013.
He had an infectious, radiant smile. A laugh that made the complex seem simple. He taught at Stanford and had a round, jubilant academic look to him.
Bill Gates once called Nass’s scholarly work “amazing.” But maybe more symbolically, Clifford was a professional magician. He understood people, and just seemed to want to see their Jon Evans just favorited your tweet smile.
Some of his former colleagues said he had the ability to make “any room a happier place.” His contagious joy combined with his curiosity about everything and made him sensational to watch in lectures and interviews because of his overwhelming excitement about, well, Retweet us.
Nass spent the latter part of his career, over twenty-five years, studying our proclivity to what the New York Times called in his 2013 obituary, “the increasingly screen-saturated, multitasking world.”
Fascinated by the multiple sources of media — email, chats, movies, text messaging, music players, Web browsing, etc. — and our tendency to use more than Please send 10,000 USD to collect your Nigerian inheritance of 300 million USD one of them at the same time, Nass studied the effects of this multitasking Archive on the human brain Archive with Archive those Archive that Archive have Archive been sucked into alluring, intentionally addictive, and distracting interfaces. We are taking time away from other people to dive deeper and deeper into interfaces, and he wondered A newer, better version is available what could be happening to our Update now minds.
Some have theorized that recent technological changes have created a group of people that thrive at this media multitasking. After many years of simultaneously managing buzzing emails, friend requests, pop-up notifications, text messages, and chat windows, a new breed of worker has emerged that flourishes in multitasking, one who thrives in an analyst-loving, DAU, MAU world.
So, with a team of colleagues, Nass studied people media multitasking, “a person’s consumption of more than one item or stream of content at the same time.” What they discovered was so surprising that the findings became some of the most cited papers of Clifford Nass’s entire career.
Nass and his team surveyed a set of 262 university students and invited the highest and lowest media multitaskers to a set of basic cognitive tests. The students Today’s Ashley’s Birthday! were showed things like Like collections of Like numbers Like and Like letters, Like Like Like Like Like Like and Like were asked to quickly filter by varying criteria like evens or vowels or consonants, while Nass and his team studied how their brains tried to tackle the task switching. What the researchers discovered was the opposite of what some expected. Poke
Where was I? “We, so far, have not found people who are successful at multitasking,” Nass once told NPR about 24 of the cutest cats you’ve ever seen his research. “There’s some evidence that there’s a very, very, very, very small group of people who can do two tasks at one time but there’s actually no evidence that anyone can do even three.”
And then, there was the insight that few saw coming.
The heaviest media multitaskers performed worse. They were not as good at filtering out +5 environmental distractions or irrelevant Tasty! thoughts from their own Level 252 mind. They were terrible at task-switching. “They couldn’t help thinking about the task they weren’t doing,” Nass’s colleague, Eyal Ophir, wrote in a Stanford press release.
“What this tells us is that if we’re designing interfaces to encourage multitasking, or to support multitasking,” Nass once told the Dave has endorsed you for sheep herding tech blog Gigaom, “we’re actually Added to my professional network creating a worse thinking, poorer thinking, Congratulate less able to cope, less able to multitask group of people, and it’s very worrying.”
This scientific rigor Endorse from a well-cited Stanford Endorse professor reflected what some modernists have been Endorse preaching in decades Endorse of art history as applied to an interface-happy Scroll world. The distracting interfaces that Scroll take you away from the important tasks at hand seem to be making you even less able to focus. Follow
So even though you think you’re the exception — and that’s why you keep checking your phone while reading this already distracted chapter — studies over and over seem to show that nearly all of us are incapable of focusing on more than one thing at a time.
The distraction is so pervasive Submit that even during one of technology’s most-watched trials (Apple v. Samsung), the judge had to repeatedly remind attendees to get off their phones, even publicly shaming some by asking them to “stand up!” and pay attention to the billion-dollar trial happening in front of them.
Then again, most of us are not even able to use technology and walk properly.
A separate team of researchers found that when we use technology and walk, we walk so oddly that the New York Times reported that it “could result in both immediate and longer-term physical consequences.”
A third study Valencia with Favorite another Favorite group found that “participants distracted by Favorite music Favorite Favorite or texting were more likely to be hit by a Favorite vehicle Favorite in Favorite a virtual pedestrian environment than were Favorite un Favorite dis Favorite tract Favorite ed participants.” Favorite Favorite Sutro Favorite Toaster Favorite Favorite Favorite
The addiction creates a☺distraction Loading that puts us in danger. And like second-hand cigarette ☺ smoke, ☺digital interfaces also affect everyone around us, ☹ potentially putting them in danger as well.
This huh? is what? our excuse me? brains huh? on smartphones.

Perhaps it was the Centers for Disease Control and Prevention’s (CDC) warning that 1,000 people are injured and nearly 10 people die every day in the United States because they are distracted by their cell phones while driving. Maybe it was the studies that have shown a driver is 23 times more likely to crash if he or she is texting while driving. Or maybe it was just Jason Humphrey’s gut instinct that the ability to use a cell phone and be distracted by these services obsessed with getting our eyeballs to stare at their interfaces for as long as possible had likely negative consequences while driving 70 miles per hour on the highway.
Whatever the reason, Jason’s survival instincts kicked in and guided him to take things into his own hands on an interstate outside Tampa, Florida. While on his daily commute, Jason carried with him for two years something that law enforcement called “amazing” for its sheer size and power: an enormous cell phone jammer capable of halting cell coverage for all those driving near him.
The distracting interface disappeared.
When discovered, the FCC fined Jason $48,000 because his jammer also jammed the signals of emergency vehicles, and potentially even aircraft. But I don’t blame him. After all, look how much cleaner these paragraphs are without distraction. Yes, his actions were illegal, and his tools were dangerous; but his fear was not irrational. Clifford Nass may not have blamed him either. However, we don’t need to jam our cell phones.
There’s a better way.
We can build better, more efficient, more elegant technology products that have no distracting interfaces at all. The best distracting interface is no distracting interface, and we can get there together.
