As we use our mobile phones to do more and more things, we are paradoxically able to accomplish less— even when the phones are face down and turned off.

My last column  explored how smart glasses (“heads up display” or “HUDs”) will increase the amount of digital information we look at, with the ironic twist that these same devices will erode our shared experience of reality. But we don’t need to look to a future technology to see how challenging it is to pay attention to what’s around us. We already carry a dislocating technology around in our pockets: our phones.
I’m deliberate when I say “dislocating” rather than “distracting,” because we’re not necessarily distracted: often we’re fiercely focused on our phones, but we’re dislocated because unless we’re taking pictures or videos we’re not engaged with our immediate physical environments. Distraction is a subset of dislocation.
The charts below show the many ways we use our phones, as described in the newest version of Center’s longitudinal “Surveying the Digital Future” report (it comes out next month):
Use of mobile phone functions
(Internet users who use mobile phones or smartphones)
As the report will observe, texting (93%) has edged out talking (92%) as the most common use of a mobile phone because texting increased six percent year over year while talking stayed flat.
It’s easy to get sucked into data on the individual functions (for example, 67% of people take videos with their phones, a nine percent increase), but doing so misses the big picture: with the exception of talking, Americans have increased their use of every mobile phone function over four years (2012 to 2016).
Phones and the Future of Focus
As with all technologies, increased mobile phone use has both a plus side and a downside.
On the positive side, we’re more connected to our loved ones and the information we want than ever before. We get news of the world instantly and store our important information — from shopping lists to medical documents to that pinot grigio we liked so much in that restaurant that time that we took a picture of the label — in our phones and online where we can always get to it. (I’m the king of productivity apps  and can no longer imagine life without Evernote.) With games and apps and email and social media, mobile phones have engineered boredom out of our lives because there is always something fun to do.
But on the negative side, we use our phones more often to do more things, and that time and attention have to come from somewhere — they come from our engagement with the physical reality around us, including the people we are with who increasingly feel ignored unless they too have their noses in their smartphones. If we’re playing Candy Crush waiting in the supermarket checkout line, then we’re not chatting with the cashier or the other people in line who might have something interesting to say. While it sucks to be bored, boredom leads to daydreaming, and most of the great ideas in human history started with a daydream.
First we’re dislocated, then we’re distracted. In other words, when we finally want to focus on the world around us, it’s getting harder to do so because of our mobile phone use. This is the finding of an important study that came out in the Journal of the Association for Consumer Research in April.
The article — “Brain Drain: The Mere Presence of One’s Own Smartphone Reduces Available Cognitive Capacity”  by Adrian F. Ward, Kristen Duke, Ayelet Gneezy and Maarten W. Boz — usefully distinguishes between the things we think about (the orientation of our attention) and how much energy we have to think about those things (the allocation of our attention).
Mobile phones, the authors find, suck attentional energy away from non-phone-based activities, and since we have a limited amount of attention to spend, we’re less capable when we have a task at hand and in front of us.
What’s startling about the study is that mobile phone distraction does not just happen when our phones are on, beeping and flashing and vibrating for our attention. Our mobile phones reduce our ability to function even when the phones are turned off and face down on the table or desk where we’re working. As the authors observe, trying to increase your focus using “intuitive ‘fixes’ such as placing one’s phone face down or turning it off are likely futile.”
Performance gets slightly better if the phone is out of sight in a pocket or bag. Performance substantially increases only when the mobile phone is in another room, entirely out of sight and somewhat out of mind. And the more dependent you are on your mobile phone, the more your focus blurs when your phone is in sight or nearby.
It gets worse: the data shows convincingly that our ability to perform erodes if our phones are nearby, but we do not recognize that degradation of performance:
Across conditions, a majority of participants indicated that the location of their phones during the experiment did not affect their performance (“not at all”; 75.9%) and “neither helped nor hurt [their] performance” (85.6%). This contrast between perceived influence and actual performance suggests that participants failed to anticipate or acknowledge the cognitive consequences associated with the mere presence of their phones.
In other words, we think that we can handle the distraction that comes with our phones being around, but we can’t. In this regard, mobile phones are a bit like drunk driving or texting while driving: we think we can do it without consequence, but often we aren’t aware when we’re impaired and not able to function until it’s too late. (Psychology Today has a nice summary of the study findings .)
Implications: Budgeting Attention
We have a limited amount of attention: this is why a common metaphor for directing our attention towards someone or something is “to pay attention.” Attention is like a currency that we can budget or hoard, but we tend not to do so. Instead, we are attention spendthrifts, throwing our cognitive capacity at all the tasty tidbits that come out of our screens.
We use our phones more often to do more things, and that time and attention have to come from somewhere — they come from our engagement with the physical reality around us, including the people we are with who increasingly feel ignored unless they too have their noses in their smart phones. With games and apps and email and social media, mobile phones have engineered boredom out of our lives because there is always something fun to do. While it sucks to be bored, boredom leads to daydreaming, and most of the great ideas in human history started with a daydream.
The problem with the “pay attention” metaphor is that it obscures something important: our attention can disappear without our having made a conscious decision to pay. For example, when we have notifications enabled on our laptops, tablets, and mobile phones — especially the latter — those bleeps and flashes and buzzes are attention taxes that we don’t realize we’re paying.
What the “Brain Drain” study shows is that even if we have our phones turned off and face down, we’re still paying an attention tax that acts like hidden fees on credit cards.
Brain Drain is different than Information Overload because with Brain Drain there is no information: just the potential for information. Likewise, Brain Drain is different from FOMO (Fear of Missing Out), because Brain Drain happens even when we aren’t fretting about what might be going on somewhere else.
The paradox of mobile phones is that as we use them to do more and more things, it becomes harder and harder to do any one thing. Always using our everything devices mean that we’re often nowhere in particular, and in order to be somewhere we have make a pre-emptive, conscious decision to put the everything device into an entirely different room.
That’s hard to do.
