This post, shortened here, appeared June 9, 2015. Nicholas Carr writes about technology and culture. He is the author of The Glass Cage: Automation and Us that examines the personal and social consequences of dependency on computers. His previous work, The Shallows: What the Internet Is Doing to Our Brains, was a 2011 Pulitzer Prize finalist and a New York Times bestseller.
“Everything is going too fast and not fast enough,” laments Warren Oates, playing a decaying gearhead called G.T.O., in Monte Hellman’s 1971 masterpiece Two-Lane Blacktop. I can relate. The faster the clock spins, the more I feel as if I’m stuck in a slo-mo GIF loop.
It’s weird. We humans have been shown to have remarkably accurate internal clocks. Take away our wristwatches and our cell phones, dim the LEDs on all our appliances and gizmos, and we can still make pretty good estimates about the passage of minutes and hours. Our brains have adapted well to mechanical time-keeping devices. But our time-tracking faculty goes out of whack easily. Our perception of time is subjective; it changes, as we all know, with circumstances. When things are happening quickly around us, delays that would otherwise seem brief begin to feel interminable. Seconds stretch out. Minutes go on forever. “Our sense of time,” observed William James in his 1890 Principles of Psychology, “seems subject to the law of contrast….
“A compression of time characterizes the life of the century now closing,” wrote James Gleick in his 1999 book Faster. Such compression characterized, as well, the preceding century. ‘The dreamy quiet old days are over and gone forever,” lamented William Smith in 1886; “for men now live, think and work at express speed.” I suspect it would take no more than a minute of googling to discover a quotation from one of the ancients bemoaning the horrific speed of contemporary life. The past has always had the advantage of seeming, and probably being, less hurried than the present.
Still, something has changed in the last few years. Given what we know about the variability of our time sense, it seems clear that information and communication technologies would have a particularly strong effect on our perception of time. After all, those technologies often determine the pace of the events we experience, the speed with which we’re presented with new information and stimuli, and even the rhythm of our interactions with others. That’s been true for a long time — the newspaper, the telephone, and the television all quickened the speed of life — but the influence must be all the stronger now that we carry powerful and extraordinarily fast computers around with us all day long. Our gadgets train us to expect near-instantaneous responses to our actions, and we quickly get frustrated and annoyed at even brief delays.
I know from my own experience with computers that my perception of time has been changed by technology. If I go from using a fast computer or web connection to using even a slightly slower one, processes that take just a few seconds longer — waking the machine from sleep, launching an application, opening a web page — seem almost intolerably slow. Never before have I been so aware of, and annoyed by, the passage of mere seconds.
Research on web users makes it clear that this is a general phenomenon. Back in 2006, a famous study of online retailing found that a large percentage of shoppers would abandon a merchant’s site if its pages took four seconds or longer to load. In the few years since, the so-called Four Second Rule has been repealed and replaced by the Quarter of a Second Rule. Studies by companies like Google and Microsoft now find that it takes a delay of just 250 milliseconds in page loading for people to start abandoning a site. “Two hundred fifty milliseconds, either slower or faster, is close to the magic number now for competitive advantage on the Web,” a top Microsoft engineer said in 2012. To put that into perspective, it takes about the same amount of time for you to blink an eye.
A recent study of online video viewing provides more evidence of how advances in media and networking technology reduce the patience of human beings. The researchers, affiliated with the networking firm Akamai Technologies, studied a huge database that documented 23 million video views by nearly seven million people. They found that people start abandoning a video in droves after a two-second delay. That won’t come as a surprise to anyone who has had to wait for a YouTube clip to begin after clicking the Start button. (The only surprise was that 10 percent of people were willing to wait a full fifty seconds for a video to begin. Almost a whole minute! I’m guessing they spent the time checking their Facebook feed.) More interesting is the study’s finding of a causal link between higher connection speeds and higher abandonment rates. Check it out:
Every time a network gets quicker, we become antsier. “Every millisecond matters,”says a Google engineer.
As we experience faster flows of information online, we become, in other words, less patient people. But impatience is not just a network effect. The phenomenon is amplified by the constant buzz of Facebook, Twitter, Snapchat, texting, and social networking in general. Society’s “activity rhythm” has never been so harried. Impatience is a contagion spread from gadget to gadget.
All of this has obvious importance to anyone involved in online media or in running data centers. But it also has implications for how all of us think, socialize, and in general live. If we assume that networks will continue to get faster — a pretty safe bet — then we can also conclude that we’ll become more and more impatient, more and more intolerant of even milliseconds of delay between action and response. As a result, we’ll be less likely to experience anything that requires us to wait, that doesn’t provide us with instant gratification. That has cultural as well as personal consequences. The greatest of works — in art, science, politics, whatever — tend to take time and patience both to create and to appreciate. The deepest experiences can’t be measured in fractions of seconds.
It’s not clear whether a technology-induced loss of patience persists even when we’re not using the technology. But I would hypothesize (based on what I see in myself and in others) that our sense of time is indeed changing in a lasting way. Digital technologies are training us to be more conscious of and more antagonistic toward delays of all sorts — and perhaps more intolerant of moments of time that pass without the arrival of new messages or other stimuli. Call it the patience deficit. Because our experience of time is so important to our experience of life, it strikes me that these kinds of technology- and media-induced changes in our perceptions can have particularly broad consequences. How long are you willing to wait for a new thing? How many empty seconds can you endure?
