Overload: How technology is bringing us too much information
Fifty, sixty years ago, television was the threat. It would, we feared, rot our children's minds, and our minds -- diminishing our attention span, addicting millions to mindless drivel.
There are those who say, "And they were right!"
So, what's different about today and the internet?
"I think every technology that changes the way people live inspires exaggerated hopes and fears," said technology critic Nicholas Carr, who has spent most of the past decade worrying, and warning, about the dangers of social media and the internet -- posing the famous question: "Is Google making us stupid?"
"We've never had a technology like a smartphone, where it's with us all the time," Carr said. "So, I think this is something new in human history. And I think we're starting to see the science -- behavioral science, sociological science -- that is pointing to how deeply this technology is affecting us, because we're using it so intensely."
That's the focus of Byron Reeves' research. He's a professor, a "media psychologist," at Stanford University. Reeves developed a way to accurately track our digital lives. How do those two-to-three hours a day spent on the phone break down?
"To view that three hours of content, on average, I am turning that phone on and off 300 times a day," said Reeves. "And that's just the average. There are a lot of people that are turning it on and off 500, 600, 700, 800 times a day. So it's going on, going off for an average of ten seconds."
Take, for example, a news story on "Sunday Morning": "How long does one last -- two minutes? Ten minutes?" asked Reeves.
"This one will probably last nine, ten minutes," said Koppel.
"I'll just talk about Stanford students for a second. If you put software on laptop computers and smartphones to measure how long they spent with any given segment of life that they intend to do -- how long they wrote their paper, how long they watch a news story -- it's about ten seconds."
Koppel interjected: "But wait a second: I've got a nine-minute piece here! I want 'em to watch the whole damn thing!"
"Not gonna do it, most likely!" Reeves replied. "It's going to be atomized, and fragmented."
That sounds like a formula for confusion.
"It could be," Reeves said. "But oftentimes we find it's done with a progression of screens that at least kind of make sense to me. 'Cause you might've said something that's really important to me in minute two, and I want to get right to that."
Nicholas Carr said, "What becomes important to us is the next new thing that comes along in a matter of seconds; that's what grabs our attention. And not only do we begin to ignore the need to think deeply and quietly and contemplatively about things, but we begin to see that as a waste of time, because it stops you from grabbing the next new bit of information."
Facebook was the first among the social media companies to turn those short and shallow attention bites into a hugely profitable business model. They realized that advertisers could just be given what amounts to a one-click road map to our brains -- showing them, as we flitted from one subject to another, what we liked and didn't like.
Meet Justin Rosenstein, co-inventor of the "Like" button: "The idea was, 'Could we make it one-click, really easy for people to be able to share little bits of positivity and affirmation in the world?'"
"And when did you first come to realize that there were, I don't know if you want to describe them as problems, 'complications'?" asked Koppel.
"Yeah, it's been interesting to see how it's played out as this kind of double-edged sword. I think it's very dangerous right now to have a business model in which the way that these companies make money is by selling people's attention to advertisers," said Rosenstein. "So, regardless of whether they have good or bad intentions, the financial incentives just lean you more and more toward trying to get people to stare at their phones.
"And, as a result, we see that influencing the level of depth that we're able to think at. We see that influencing our politics."
