Imagine if I could offer you a pill

0:02

that gave you the following benefits.

0:04

One, your symptoms of anxiety and

0:07

depression would significantly reduce.

0:09

Two, your overall sense of

0:11

moment-to-moment life satisfaction would

0:13

improve. And three, you would gain

0:17

substantially more ability to

0:19

concentrate.

0:21

Now, to make this even more enticing,

0:23

let's say this pill would deliver you

0:25

those benefits in only 2 weeks. If such

0:28

a drug existed, it would be a

0:30

blockbuster. Now, the bad news is

0:33

there is no such pill that can do this.

0:35

The good news, however, is that

0:37

according to a major new research paper,

0:40

there's a simple intervention for your

0:42

digital habits

0:44

that can deliver all of those promises.

0:46

I'm talking about something that's free

0:48

and that you can put in place with

0:50

minimal preparation, something that you

0:51

could start implementing

0:54

today.

0:55

Well, it's Monday, which means it's time

0:57

for an advice episode of this show, and

0:59

clearly this is a perfect type of topic

1:02

to dive deeply into. So, here's what

1:05

we're going to do.

1:06

I have the paper here. We're going to go

1:07

through it. I'll start by describing the

1:09

intervention they studied and quantified

1:11

the exact benefits that they measured.

1:13

Then we'll look closer at the mechanisms

1:16

that the researchers believe explain why

1:19

this intervention works so well. And

1:22

then we'll end with three pieces of

1:24

advice of my own for how to maximize the

1:27

chances that you will succeed with this

1:29

intervention if you choose to try it.

1:33

So, if you've been fed up with your

1:34

distracted digital life, this is an

1:37

episode you definitely need to hear.

1:40

As always, I'm Cal Newport, and this is

1:44

Deep Questions, the show for people

1:46

seeking depth in a distracted world.

1:56

All right, so we're going to proceed

1:57

here by addressing three key questions.

2:02

The first question,

2:04

what was the intervention studied in

2:07

this research paper?

2:08

Well, if you look at the title of the

2:10

paper, it sort of gives it away. Here is

2:11

the title.

2:13

Blocking mobile internet on smartphones

2:15

improves sustained attention, mental

2:17

health, and

2:19

subjective well-being.

2:21

All right, let's look a little bit

2:22

closer at this. What do they mean by

2:24

blocking mobile internet? Well, they

2:26

used an app blocking tool called

2:29

Freedom.

2:30

And what they did is they set it up to

2:31

block internet-powered apps like social

2:34

media and the web browser, but leave

2:36

things like instant messaging and phone

2:39

calls alone.

2:41

Um this is key, as a lot of people know,

2:43

especially parents in the audience,

2:45

you need the ability to have a phone on

2:47

which you can do calls or messages or

2:49

WhatsApp. I I I checked it recently,

2:51

Jesse. I'm on three

2:52

different parental WhatsApp groups right

2:55

now that I have to monitor. Uh and with

2:58

three kids in school, I would say I get

2:59

called by the school nurse like roughly

3:02

once a month. All right, so they figured

3:04

out how to

3:05

block the internet without making you

3:07

have to live without the other

3:09

functional benefits of a smartphone.

3:11

Now, here's what's critical about this

3:13

research. Part of what made it good was

3:15

they could then check compliance. They

3:17

could look at the log produced by the

3:18

blocking software and make sure that

3:20

their research subjects actually

3:23

kept the blocking on. That they weren't

3:25

occasionally going around it. So, that

3:28

made a big difference. Then, to get even

3:29

better results, they did something even

3:31

more impressive. They made this a

3:32

randomized controlled trial. So, they

3:34

recruited a group of participants

3:37

and then randomly divided them

3:39

into a group that was going to have the

3:41

internet blocking and then a group that

3:42

was not, so that they could really be

3:44

comparing what was the difference

3:45

between these two groups and not

3:47

accidentally measuring things like

3:48

self-selection effects.

3:50

As the experiment went on, they could

3:53

measure the impact with various means.

3:56

They had surveys that they would have

3:58

the participants filled out. They had

4:00

various tests like test of attention

4:01

that they would have the participants do

4:03

at various times and they would do

4:04

something called random experience

4:06

sampling.

4:08

Where they would randomly text the

4:09

participants and say, "Hey, tell me

4:11

right now in this moment how you are

4:13

feeling." This is sort of the gold

4:14

standard in social psychology for

4:16

measuring

4:17

people's subjective well-being on

4:19

average.

4:21

Okay, so that was the experiment and

4:22

they had uh the intervention group do

4:24

this for 2 weeks

4:26

while the control group did not. And

4:28

then there there were some more

4:28

complexities after that where then they

4:30

swapped and the control group started

4:32

using them and they measured what

4:33

happened with the intervention group for

4:34

the week that followed. But that was the

4:35

core of the experiment.

4:37

What did they find? Well, I'm going to

4:38

put a couple plots up on the screen here

4:41

for people

4:42

uh who are watching. Okay, so this first

4:44

plot here is looking at sustained

4:47

attention ability. I want you to look at

4:48

the blue lines. This is the intervention

4:50

group. And between the beginning of the

4:53

experience and time point two, so two is

4:55

after 2 weeks, we see this blue line

4:56

goes way up. A marked increase in the

4:59

ability to pay attention.

5:01

Then as we go forward uh it falls a

5:03

little bit but not all the way back down

5:04

to baseline. So even after they started

5:06

using their phone for the internet

5:07

again, they still had some attention

5:09

left. All right, what about mental

5:11

health? An even more dramatic effect

5:12

here. Look at this blue line.

5:15

That's the intervention group. One is

5:17

right before the experiment starts. Look

5:18

at how high that jumps up by the end of

5:21

the experiment. It's a massive increase.

5:22

And look what happens when they measured

5:24

in at the third time point after they

5:25

started using their phones again.

5:27

Their mental health began going down.

5:29

They had a long after effect of benefits

5:31

from spending those 2 weeks without

5:33

mobile internet.

5:34

Here's the third chart, subjective

5:36

well-being. Once again, look at that

5:37

blue line. From the beginning of the

5:39

experiment to the end of the 2-week

5:40

period, we see a massive jump. And

5:42

again,

5:44

as we go from time period two to a

5:45

period three and they start using their

5:46

phones again,

5:48

it falls, but we still get some after

5:51

effect benefits

5:53

from the two weeks they spent without

5:54

using their phone. So, these are notable

5:57

results and they were delivered really

5:58

fast.

6:00

In these sort of prospective randomized

6:03

control studies where you're really

6:04

comparing one group to another,

6:06

to see such a large jump

6:09

on such important metrics in only two

6:11

weeks is pretty rare.

6:13

It gives us the sense that maybe we were

6:16

underestimating just how much damage to

6:18

our ability to pay attention,

6:20

our mental health and our subjective

6:21

well-being, maybe we were really

6:22

underestimating what a hit we were

6:24

taking

6:25

by being using the internet on our phone

6:28

so constantly.

6:30

All right, so those results then

6:31

motivate a natural follow-up question.

6:33

That's what they saw, but why did they

6:36

see that?

6:38

What were the mechanisms that mediated

6:40

these improvements in those factors when

6:42

they stopped using mobile internet on

6:45

their phone? So, that's our second

6:46

question here. What explains

6:49

these results?

6:51

Now, fortunately, the researchers also

6:52

looked at this question. They measured

6:54

many factors during the experiment

6:56

before and after to try to figure out

6:58

what changed

7:00

during the period of not using mobile

7:02

internet

7:03

that seems at least like it's likely

7:06

candidate to be mediating the positive

7:08

results that they saw.

7:10

The first thing they looked at was just

7:11

the obvious top-line number.

7:13

When you take mobile internet off of

7:15

your phone,

7:17

how much less do you look at it?

7:19

And they discovered that actually

7:21

significantly less.

7:22

The average daily screen time before the

7:24

experiment began was 304 minutes.

7:28

By the end of the experiment, that had

7:29

dropped down to 161 minutes. So, they

7:31

basically dropped the amount of time

7:33

they were looking at their screens by

7:34

about a factor of two

7:36

when you took mobile internet off of the

7:38

phones.

7:40

Okay, so they freed up the sort of 150

7:42

or so minutes each day that they used to

7:45

be looking at mobile internet devices.

7:48

How did this then lead to them being

7:51

happier, less mental health impacts, and

7:53

ability to focus more?

7:55

Well, the researchers went on to the

7:56

isolate four what they called mediation

7:59

factors

8:00

that emerged as having strong changes

8:03

during the experimental period, and it's

8:04

their best guesses at what is actually

8:06

mediating the positive

8:08

dependent variable effects. So, here's

8:10

the four mediation factors that they

8:12

measured during the experimental period.

8:15

The subjects spent more time doing

8:17

meaningful offline activities.

8:19

They experienced more social

8:21

interaction.

8:23

They slept more.

8:25

And their sense of self-control

8:28

increased.

8:30

Let's think about those for a second.

8:32

So, the first three

8:33

meaningful offline activities, more

8:35

social interaction, and more sleeping

8:37

the researchers are saying this is

8:38

probably just a straight-up time

8:40

reallocation. That is where that 150

8:44

minutes that used to be looking at

8:45

internet-connected apps on the phone,

8:47

that's where it went. They just

8:48

reallocated it towards activities

8:50

that had much more positive impacts

8:53

on their daily life.

8:55

Now, here's what this tells me.

8:57

If we see pretty consistently that once

8:59

you take

9:00

highly optimized internet distract power

9:03

distracting apps off of phones, if we

9:04

see this in the research

9:06

the subjects all move towards those much

9:09

more meaningful activities, it tells me

9:10

that we're wired to do the right thing.

9:14

That if you don't have extra constraints

9:16

on us, if you put us in a situation

9:18

where we're bored

9:19

we have natural drives that will drive

9:21

us towards let's go do something

9:23

meaningful. Let's talk to other people.

9:25

I'm tired, why don't I actually go to

9:27

sleep?

9:29

And what we want to understand is

9:30

happening with our phones is that it's

9:31

basically just short-circuiting our

9:33

natural drives. If left our own devices,

9:35

we tend to do the things that are

9:38

good for us from a subjective well-being

9:40

perspective.

9:42

And it's only when we have these sort of

9:43

outside tools come in that hijack those

9:45

drives that we end up in trouble. I

9:46

mean, we see similar things with drugs

9:47

and alcohol where uh it will make our

9:49

lives worse because it's it's hijacking

9:52

our drives or our mind in a way that

9:53

gets us away from the activities we

9:55

normally would be doing that would be

9:56

beneficial. It looks like the phones are

9:57

doing the same thing. If we could just

9:58

get those highly engineered distracting

10:00

apps out of our life,

10:02

we will naturally start doing things

10:04

that are going to make us

10:05

much happier. But what about that fourth

10:07

mediation factor, which was a sense of

10:09

increased self-control?

10:12

Here's my understanding of what's going

10:14

on here, and this is sort of my theory

10:15

based on my own study

10:17

of these issues.

10:19

So, one of the things that happens when

10:21

you have your phone with you at all

10:22

times like most people do,

10:24

and you have these internet-based apps

10:26

that are highly distracting on the

10:27

phone, as I've talked about many times

10:29

before on this show,

10:31

the short-term motivation centers in

10:33

your brain

10:34

learn that picking up that phone and

10:36

tapping on one of those apps

10:39

is very likely to give you a reward

10:40

signal. The expected value is high, and

10:42

because of that, because you have such a

10:44

clean reward signal coming out of those

10:45

apps,

10:47

your short-term motivation center of

10:48

your brain is constantly voting for

10:50

picking up your phone.

10:52

And you feel this as like a constant

10:53

urge for distraction that that pulls you

10:55

away from other things you might want to

10:57

do or prevents you from doing those

10:58

things in the first place, and it can

11:00

make you feel

11:02

like you don't have control over your

11:03

own body or mind. You're like, "Why did

11:05

I just spend 150 minutes on TikTok? I

11:08

didn't want to do that."

11:09

So, it leaves you feeling like you don't

11:10

have much self-control.

11:12

Now, on the flip side, when you get

11:13

those apps out of your life, the

11:14

short-term motivation center of your

11:16

brain is no longer voting for picking up

11:17

your phone so strongly, and you find

11:19

yourself able to do other things more

11:21

easily.

11:23

Because you do not have to overcome

11:25

the vote of your brain saying, "Hey,

11:27

let's pick up the phone." It's not

11:28

nearly as strong anymore. What is that

11:31

going to feel like?

11:32

I have more self-control.

11:34

And so, a course that was going to pick

11:35

up on surveys is when you turn off

11:37

mobile internet on your phone,

11:39

you will begin to experience your day

11:42

as one in which you have much more

11:43

control or autonomy over what you do,

11:45

which is also going to be obviously a

11:46

very positive factor.

11:49

But, go to the end of the paper. Here's

11:50

one of the thing the authors say.

11:53

I'm quoting here.

11:55

These results provide

11:57

causal evidence that blocking mobile

11:59

internet can improve important

12:00

psychological outcomes

12:03

and suggest that maintaining the status

12:05

quo of constant connection to the

12:06

internet may may be detrimental to time

12:08

use, cognitive function, and

12:11

well-being.

12:13

And to put that conclusion more plainly,

12:14

constant access to the internet through

12:16

mobile devices is causing way more

12:18

problems than most of us guessed. It is

12:20

making us miserable. It really is an

12:22

emergency.

12:24

But, for all the urgency of this

12:26

problem, the solution fortunately looks

12:28

to be pretty simple.

12:30

Block mobile internet on your phone.

12:32

After even just 2 weeks, you will

12:34

realize just how much you were missing

12:36

in your life.

12:37

Now, let's take a quick break to hear

12:40

from some of our sponsors.

12:42

Hey men,

12:43

you need to take better care of your

12:46

skin.

12:47

The best way to do this?

12:49

With Caldera Lab. Caldera Lab makes

12:51

high-performance skin care designed

12:52

specifically for men's skin. Now, this

12:54

is important because men's skin is 25%

12:57

thicker,

12:58

oilier, and ages differently from

13:00

women's, which means men need clean

13:02

formulas engineered for their biology.

13:06

Now, Caldera Lab has you covered here

13:08

because they offer three great products.

13:11

The first is actually called The Great.

13:13

It's a lightweight anti-aging serum,

13:16

which absorbs in seconds

13:18

and leaves your skin looking firmer,

13:20

brighter, and just healthier overall.

13:22

The second product is called The

13:24

Hydrolayer. With just one, the Men's

13:27

Health Grooming Awards for best

13:28

anti-aging moisturizer. You put that on

13:31

daily. And finally, they have their eye

13:32

serum,

13:33

which targets the most visible signs of

13:35

aging,

13:37

puffiness, dark circles, and fine lines

13:40

around the eye areas. Look, let me tell

13:42

you from experience, these three

13:44

products work. Like, I didn't know that

13:45

you're supposed to put on moisturizer,

13:47

but it really does make a difference. If

13:49

you use these daily, it is a small habit

13:52

that will produce big results.

13:54

So, go to calderalab.com/deep

13:57

and use the code deep for 20% off

14:00

your first order.

14:03

I also want to tell you about another

14:04

new sponsor, our friends at Larridan.

14:06

Now, here's something I've learned as

14:08

someone who writes about technology.

14:11

Sometimes figuring out how best to use a

14:13

new tool can be just as hard

14:16

as innovating the tool in the first

14:18

place. And this certainly seems to be

14:19

the case with AI right now,

14:21

where we have teams that are rushing to

14:22

deploy dozens of different tools with no

14:25

clean way of figuring out which of these

14:27

tools is actually helping. And

14:28

sometimes,

14:30

without this feedback, new tools can

14:32

make things worse rather than better.

14:35

Which is all to say,

14:36

the real challenge right now isn't

14:38

adopting AI, it's understanding how it's

14:40

being used and how to maximize its

14:42

value.

14:44

This is exactly what Larridan focuses

14:46

on. Larridan gives a clear view of AI

14:48

tool adoption and how teams are using

14:51

them daily. No more guesswork. It tracks

14:55

real usage data and outcomes, so you can

14:56

connect AI activity to actual business

14:59

results. It can even help you enforce

15:02

internal policies and manage risks,

15:05

both of which are critical as AI

15:06

continues to grow.

15:09

If AI is already part of your

15:10

organization, now's the moment to get

15:13

control of it.

15:14

15:17

15:21

That's Larridan, l a r r i d i n

15:26

15:27

All right, let's get back to the show.

15:30

All right, so that's where the paper

15:31

ends, but this leaves us with our third,

15:34

final, and most practical question.

15:38

How do I successfully stick

15:41

with this intervention?

15:44

So, if you know the thing to do is to

15:45

spend 14 days blocking mobile internet

15:47

on your phone and you get all these

15:48

benefits,

15:49

how do we make sure we'll stick with

15:50

this?

15:52

Well, this is a relevant question.

15:53

There's a key data point from early in

15:55

the paper

15:57

that should give us pause. They had

15:58

originally recruited right around 500

16:00

participants for this study,

16:03

but only 25.5%

16:05

of the participants remained compliant

16:07

throughout the whole experiment. Now,

16:08

remember, they could check compliance

16:09

exactly because they could look at the

16:10

logs of the blocking software.

16:14

Now, I assume some of this

16:15

non-compliance was actually unrelated to

16:17

the internet blocking. Just people got

16:19

busy or tired of the surveys and the

16:22

tests and the experience sampling.

16:23

They're like, "Ah, forget it. I don't

16:24

want to do it."

16:26

But, the sense you get from reading the

16:27

paper is that a lot of this measured

16:29

non-compliance was people getting around

16:32

the mobile internet blocking. They could

16:33

turn it off. Now, it would be logged if

16:34

they did, and then they wouldn't be

16:35

counted in the data, but you could turn

16:37

it off, and it seemed like a large a

16:38

number of people at some point

16:40

circumvented it at least a little bit.

16:43

So, this motivates a critical question.

16:45

If you want to do this experiment in

16:46

your life

16:48

to get these benefits, what can you do

16:50

to maximize the odds that you're like

16:52

the 25.5% of the participants who stuck

16:54

with the blocking and not like the 74.5%

16:58

who gave in and started using their

16:59

phone again?

17:01

Well, I came up with three tips, and if

17:03

you're going to put this into practice,

17:05

I came up with

17:07

the three tips that I think would be

17:09

helpful, okay?

17:10

All right, let's start with the first

17:11

one here. I'll reveal it.

17:14

This is dramatic, Jesse.

17:16

Those who are listening again are

17:17

missing

17:18

Avatar-style visual effects. All right.

17:21

Tip number one,

17:24

block precisely.

17:26

So, if you're going to

17:28

block internet-connected apps,

17:31

you have to be a little bit more precise

17:35

than basically saying, "Leave the phone,

17:37

leave text messaging, everything else is

17:38

blocked."

17:40

The problem is, and I'm sure a lot of

17:41

the participants face this, is that

17:42

there's many pragmatic apps on our

17:45

phones in the modern world that use the

17:47

internet or the cellular,

17:49

and you need them just to function

17:51

practically in the world, right? So, I'm

17:53

looking at my own phone, and I can see

17:56

on here, for example,

17:58

um

17:59

Parkmobile,

18:00

right? You park somewhere.

18:02

It's how we pay for parking here in DC

18:04

that uses the internet, but I need that

18:06

because I'm often parking in places.

18:09

Uh the two-factor authentication

18:11

that I use to like log in to Georgetown

18:14

or if we're logging into our system here

18:16

at our production company,

18:18

I need that on my phone so that I can do

18:20

two-factor authentication. There's a

18:21

couple other apps like that as well. So,

18:23

if you want to succeed, you can't have

18:25

those type of frustrations. So, you need

18:26

to block more narrowly. Whatever

18:27

blocking software you're using, you have

18:29

to go through and choose specific apps

18:31

to block, not just all.

18:34

The simple

18:36

advice I would give is look at the

18:37

so-called SNG apps, social media, news,

18:39

and games.

18:40

These are the ones that are really

18:41

engineered to grab your attention and

18:43

therefore create that sense of

18:44

motivation to pick up your phone.

18:47

So, go block every SNG you can find, but

18:48

you can leave the other pragmatic apps,

18:50

the weather app, the parking app, the

18:52

two-factor authentication app, you can

18:53

leave those open so that you're not

18:56

going to have uh

18:58

the the issue where you're like, "Oh, I

18:59

really need this app. Let me turn off my

19:00

blocking." And now you never turn it

19:02

back on again.

19:04

All right, so that's tip number one if

19:05

you want to succeed with this

19:05

intervention.

19:07

All right. Tip number two,

19:13

strengthen controls.

19:16

So, one of the thing that they did in

19:17

this paper is that the the software they

19:19

were using to block

19:22

mobile internet access, it wasn't

19:24

particularly strong. The subjects could

19:26

turn it off or circumvent it. It would

19:27

take them out of the sample study, but

19:29

they could do it.

19:31

This is partially experimental design.

19:33

Like the researchers didn't want to

19:35

take over completely the subjects'

19:37

phone. I mean, what if they're in an

19:38

emergency and they couldn't use it?

19:40

But it's also has to do with the reality

19:42

of iOS,

19:43

which several years ago made a change

19:45

that made it very difficult for

19:47

third-party apps to really have strong

19:49

controls over blocking on your phone.

19:51

They didn't like the idea

19:52

of a third-party app being able to

19:54

strongly block other third-party apps.

19:57

But if you can have stronger blocking,

19:58

by which I mean blocking in which

19:59

there's more friction involved in

20:01

actually turning it off, it will

20:02

significantly increase your probability

20:04

of compliance

20:06

with this intervention.

20:08

So, if you want to move just one step

20:09

above the sort of basic controls they

20:11

were doing, you can think about a device

20:13

like Brick.

20:15

Brick has a physical key fob

20:18

that becomes involved if you want to

20:19

actually turn off a particular blocking

20:22

mode. You have to touch it to your

20:23

phone. You can put this in another room

20:25

or keep it in your car or your bag.

20:27

So, you still have access to anything if

20:29

you need it, but the friction of going

20:30

to get a device and touching to your

20:31

device is often enough to give pause

20:34

and to prevent that short-term

20:35

motivation circuit from winning because

20:37

it it it sees a real cost you having to

20:39

actually de- monstrably go and get this

20:41

thing and make it clear to yourself that

20:42

you failed with your own rules.

20:44

If you want to go a step above that,

20:47

you can configure your phone. So, if you

20:48

have a partner, right? You can configure

20:50

your phone such that it's it's protected

20:52

with iOS's screen time, but it's like

20:54

you're the kid and your partner is the

20:56

parent, right?

20:58

And only they know the PIN code for

20:59

actually changing what settings are on

21:01

your phone. So, if you want to change

21:03

the blocking software,

21:05

you you have to get the number from

21:06

someone else. Again, that's a higher

21:07

level of friction, but that's really

21:09

going to work as well.

21:11

You're going to think, "Okay,

21:13

uh I'm not going to go bother like my

21:14

husband or my wife or my girlfriend or

21:16

my boyfriend to get this PIN number.

21:17

That's just admitting I failed. I guess

21:18

I I'm going to have to do without

21:21

checking Instagram

21:23

right in this moment."

21:24

All right, those are three tips. Let me

21:25

give you the third

21:28

tip to succeed with this intervention.

21:33

Lean into boredom.

21:36

This is one of the more interesting

21:37

things I saw in the paper was this idea

21:40

that

21:41

many of these subjects

21:43

naturally drifted to the same high-value

21:46

activities once you took the mobile

21:49

internet that that sort of potent

21:50

distraction out of their life. The point

21:52

is our instincts are good.

21:55

If we get rid of these sort of

21:56

artificial constraints in our lives, our

21:58

instincts for how we want to alleviate

22:00

boredom tend to be good. I want to go

22:02

hang out with people. I want to go do

22:03

something interesting.

22:06

I want to make my man at my intentions

22:08

made manifest concretely in the world.

22:11

So, you're going to feel discomfort when

22:13

you don't have access to the same apps

22:15

that you're used to delivering you

22:16

numbing or diversion. That's okay.

22:20

Feel that discomfort. Feel that boredom.

22:23

And tell yourself rewire yourself to

22:25

think the solution to this boredom is

22:27

not circumventing the blocks and going

22:30

back to having access to

22:32

apps on my phone. Let me try

22:35

other things that might get rid of this

22:37

boredom unrelated to my phone. And

22:39

that's going to drive you really quickly

22:41

towards activities that are actually

22:42

very good for you.

22:44

Just like if you're very hungry and

22:46

you're put into a food environment where

22:47

you don't have ultra-processed foods

22:49

that are hyper-palatable,

22:51

you're going to eat the things that are

22:52

good for you. You're like, "Oh, I want

22:55

you know, I have like meat here and

22:56

vegetables and fruit." Like stuff that

22:58

your body recognizes and likes. So, in

23:00

the absence of the artificial, our

23:01

instincts work really well.

23:04

So in the absence of our artificial

23:05

diversions, the boredom will drive you

23:07

towards good behavior if you let it.

23:10

Just take your phone off the table as

23:11

the solution and see what other

23:13

solutions arise in that royal wake.

23:17

And you're going to find yourself drawn

23:18

to activities that make a big

23:20

difference.

23:21

All right, so what's the long-term

23:22

vision here? Let's say you do this

23:24

intervention for 2 weeks, you feel much

23:26

better, you can concentrate, your

23:27

subjective well-being is better, your

23:28

mental health is feeling stronger.

23:31

The idea is once you get to that point,

23:34

you will follow something like my own

23:35

lead, like what I do in my life,

23:38

and permanently quit or disable these

23:40

apps that are on your phone that are

23:42

causing these diversions to make your

23:44

phone boring. Like losing your taste for

23:47

junk food.

23:48

And now you can be around potato chips

23:50

and have no desire to eat them. You will

23:51

get there when it comes to these digital

23:53

diversions. If they're not normally on

23:54

your phone and you don't normally spend

23:55

much time with them,

23:57

they become less alluring.

24:00

And what becomes more attractive is all

24:01

of the other interesting things going on

24:03

in your life. Getting a full night's

24:04

sleep, interacting in the real world

24:06

with other people,

24:08

meaningful offline activities.

24:10

So this is my advice. Take the

24:13

Take the lesson from this paper

24:16

and right away go ahead and do a 14-day

24:19

mobile internet break

24:21

on your phone.

24:23

Keep all the apps you need for your

24:24

day-to-day life. Just takes off the ones

24:26

you don't. Remember the three tips that

24:29

I mentioned so that you're more likely

24:30

to succeed with this. And if you make it

24:31

to the other end, then ask yourself like

24:33

a true digital minimalist,

24:35

"What role do I really want these

24:37

technologies to play in my life?" And

24:38

then it might be time

24:40

to make some permanent changes.

24:42

So there we go. That was a well-done

24:44

study, Jesse. It actually involved one

24:46

of the co-authors

24:47

uh is a colleague of mine at Georgetown.

24:49

>> Oh, really?

24:50

>> Yeah, from the psychology department. So

24:51

there we go. It's a pretty international

24:53

group of researchers. I see a lot of

24:54

these papers. Some Some some are bad.

24:55

This is a high-quality one. It appeared

24:57

in the uh

24:58

Proceedings of the National Academy of

25:00

Sciences Nexus open access journal, so

25:01

it's a that's actually a really solid

25:03

one. That paper's been read like 200,000

25:04

times.

25:05

>> Did you know about it before it came

25:06

out?

25:07

>> Um

25:08

I had heard rumors. I mean, I there's a

25:11

lot of papers. I kind of heard people

25:13

mention it, and then I think it was uh

25:15

newsletter director Nate who was like

25:17

telling me about this two-week paper.

25:18

And I went and read it and was like,

25:19

"Oh, this is a good one."

25:20

So, that's how we decided to

25:23

to do it on the show.

25:24

One thing, another quick break

25:26

from some of our sponsors.

25:28

This episode is also sponsored

25:31

by BetterHelp.

25:33

So, it's May now, which means it's

25:34

Mental Health Awareness Month.

25:37

This seems like a good opportunity to

25:39

remind you that if you're struggling

25:40

with your mind, you don't have to deal

25:41

with this all by yourself.

25:43

Having someone with you to listen, to

25:44

understand, and to support you can make

25:46

all the difference.

25:48

This is where BetterHelp enters the

25:50

scene. It's a service that makes it easy

25:51

for you to find and meet with a

25:54

qualified therapist. BetterHelp does the

25:56

initial matching work for you, so you

25:57

can focus on your therapy goals.

26:00

A short questionnaire helps identify

26:01

your needs and preferences, and their 12

26:03

years of experience and industry-leading

26:05

match fulfillment rate means

26:07

they typically get that match right on

26:08

the first time. But if you aren't happy,

26:10

you can switch to a different therapist

26:11

at any time

26:13

using their tailored recommendations.

26:15

BetterHelp therapists work according to

26:17

a strict code of conduct and are fully

26:19

licensed in the US.

26:31

That's betterhelp.com/deepquestions.

26:35

All right, let's get back to the show.

26:37

All right, well, that's enough uh

26:38

hearing from me. We also like to hear

26:41

from you because it's a Monday advice

26:42

episode.

26:44

We often uh introduce a second segment

26:47

in which we open our inbox

26:50

to get questions, comments, and

26:52

reactions from

26:54

my audience. If you have things you want

26:55

to send in to be covered on the show,

26:57

you can use podcast

26:59

at calnewport.com.

27:01

All right, we got some time today, Jess.

27:03

Let's do a few questions. Who do we have

27:04

up first?

27:06

>> Our first question is from Tyler, and

27:08

it's about AI and academic research.

27:11

>> All right, so Tyler says, "I imagine

27:14

you've gotten many emails with this link

27:15

already,

27:17

but just wanted to make sure it got to

27:19

you.

27:20

Keep up the good work, fellas."

27:22

All right, so what he sent me was a

27:24

Substack essay. I'll put it on the

27:25

screen here.

27:27

It's from a Substack called So, Here's

27:28

the Idea, the Organization Science

27:30

Substack, and the essay is titled More

27:32

versus Better,

27:34

part one.

27:36

Now, I actually went through and read

27:38

this essay

27:39

and enjoyed it so much that I wrote a

27:41

newsletter about it. So, the newsletter

27:42

that came out today at calnewport.com

27:44

goes deep into this. So, if this sounds

27:46

interesting to you,

27:47

go over to calnewport.com and check out

27:49

my essay today where I get into the

27:50

details on this essay. Uh you should

27:52

subscribe. I mean, this is dispatches

27:54

from the front lines of the war of depth

27:56

versus distraction. So, if you listen to

27:58

this, you should subscribe. But, let me

28:00

let me go over some of the high points

28:01

here um on the podcast. So, here's the

28:04

the basic idea.

28:06

This is a task force. The authors are a

28:08

task force that were organized by a

28:10

particular well-known journal in

28:12

organization science. It's called

28:14

Organization Science.

28:15

Um this task force was pulled together

28:18

to answer the question of what role is

28:19

AI having

28:22

in the

28:23

submissions and publications, like what

28:25

role is it having on the academic

28:27

research community that is publishing in

28:30

this journal. And they gathered really

28:32

good data because these are researchers

28:34

from a field where what you do is gather

28:36

really good data. So, they know what

28:37

they're doing here. Um I want to show

28:39

you a couple charts. I'm going to bring

28:40

this up here. All right, here's the

28:41

first chart.

28:43

So, this is labeled monthly submission

28:45

volume at Organization Science from

28:47

January 2013 until the end of 2025.

28:52

The key thing here is at the far right,

28:56

we see this massive increase in

28:58

submissions, and it happens right after

29:00

this vertical line just labeled ChatGPT.

29:02

So, the first thing they noticed is

29:05

there was a a bump during COVID-19. It

29:07

was it bumped up from what was happening

29:09

before, but it was pretty steady.

29:11

And then post-ChatGPT,

29:13

they've been having an increasing

29:16

uh rate of submissions per year. All

29:18

right, so that's chart number one.

29:20

Here's chart number two. This is monthly

29:22

submission volume by AI use category.

29:24

So, that black line is the total

29:26

submissions per month.

29:28

The dotted line in the middle is ChatGPT

29:30

gets introduced.

29:31

These lines down the bottom are

29:33

measuring how much AI was used in the

29:36

paper submitted. The orange line is 0 to

29:39

15% AI. And what you can see is as the

29:42

total volume of submissions go up,

29:45

the total fraction of those submissions

29:46

or volume of submissions that don't use

29:48

AI is going down.

29:51

So, they're clearly measuring

29:53

they are getting more AI submissions

29:56

um ever since ChatGPT came out.

30:00

I think let's see here. Ta-da. Okay. And

30:03

then here we see a chart that measures

30:05

essentially the readability of papers.

30:08

And Jesse, as you'll notice, it's pretty

30:10

flat

30:11

from 2013 through COVID-19.

30:13

And then what happens to the ChatGPT

30:15

line?

30:16

It takes a nose dive. Just a nose dive.

30:19

So, the papers become massively and

30:21

notably less readable

30:23

right around the time ChatGPT

30:25

is emerging.

30:26

Here's a couple numbers from the paper.

30:29

Among manuscripts that were uh high AI

30:32

submissions, so 70% or more of the

30:34

manuscript was generated with the help

30:35

of AI,

30:37

nearly 70% were desk rejected, which

30:39

means an editor determined they should

30:41

not be sent out for review. So, they

30:42

were so bad the editor is like, "We're

30:43

not even going to peer review on this."

30:45

By comparison, the the desk rejection

30:48

rate for low AI manuscripts, manuscripts

30:50

where there's very little AI used,

30:52

was 44%.

30:54

So, it almost doubled the chance you

30:55

would get rejected right off the bat if

30:58

it was written with the help of AI. Now,

30:59

remember the editors don't know that.

31:00

They they labeled these after the fact.

31:02

This is just strictly based on their

31:04

assessment of the quality

31:06

of the paper.

31:08

Later on, the researchers fell that

31:10

found that the the percentage of high AI

31:12

papers that made it all the way through

31:14

to the final stage where they say

31:16

revise and resubmit for publication

31:19

was around 4% whereas for low AI papers

31:22

that rate was 12%. So, you have a 3x

31:25

reduction in the probability that your

31:26

paper would actually make it through and

31:28

be published.

31:30

So, what they're finding is this is a

31:31

real problem.

31:32

AI made it easier to write and submit

31:35

papers and because of this they're

31:36

getting a ton more submissions, which

31:37

really is actually taxing their

31:39

resources because editors have to look

31:40

at these submissions and peer reviewers

31:42

have to peer review them if they're

31:43

sufficiently good.

31:45

Now, this would be okay if these were

31:47

all good submissions and we're just

31:49

strictly increasing the amount of good

31:51

science. You know, great. We're going to

31:52

now have a productivity boom in this

31:54

actual academic field, but it's not what

31:56

they saw. What they clearly measured

31:59

is AI made it faster to produce papers,

32:01

but the papers you were producing were

32:02

bad.

32:03

They were they weren't readable. They

32:05

were way more likely to be desk

32:06

rejected, way way more likely to not

32:08

make it through to accepted. And I think

32:10

this is a a good specific case study of

32:14

a more general issue

32:17

that we've been talking about recently

32:18

on this show, which is when it comes to

32:20

productivity,

32:22

making things faster

32:24

doesn't necessarily make things better.

32:27

Making it easier to technically finish

32:30

and submit a paper doesn't necessarily

32:32

necessarily mean that you are a more

32:34

productive scientist or science is

32:36

proceeding more productively.

32:39

And often you can have a reverse effect

32:42

where producing lower quality things

32:43

faster gunks up the works and prevents

32:45

the good stuff from happening. And

32:46

that's for sure is what's happening in

32:47

this particular journal.

32:49

By flooding the works with significantly

32:51

more uh submissions that are lower

32:53

quality,

32:54

I am sure that now the energy required

32:57

and the rate at which good research is

32:59

produced is down.

33:01

And we see this in our individual lives

33:03

as well. I've talked about this effect

33:04

like in

33:05

last week's podcast with Dave Epstein,

33:07

right?

33:09

You speed up one part of your life at

33:11

some work process you're doing like I'm

33:13

going to use email

33:15

like very quickly

33:16

bounce back and forth ideas with people,

33:19

but it leads to too much work on your

33:20

plate. It all piles up at the bottleneck

33:23

of you actually doing the hard work and

33:24

because you're so distracted keeping up

33:25

with all these email conversations, the

33:27

rate at which you actually finish things

33:28

goes down. And you made one thing in

33:30

your work process faster, but you made

33:32

the rate at which you produce useful

33:33

stuff slower. And this happens time and

33:35

again when we bring in digital tools

33:37

that makes one thing faster easier,

33:40

and we assume that's going to mean we'll

33:41

just become strictly better at what we

33:42

do, but they can make things worse. I

33:44

think it's a great experiment, but if

33:45

you want a if you want a shareable

33:46

version of this discussion or you want

33:48

to get some more details, go to

33:49

calnewport.com. I just wrote about it

33:50

today.

33:52

All right, Jesse, what uh what we got

33:53

next?

33:54

>> Our next message is from Emily who had a

33:57

question about our recent episode on

33:59

reversing brain rot with cognitive

34:01

fitness.

34:01

>> That was a popular episode.

34:03

>> Yeah. Yeah, especially online.

34:05

>> The kids like the term brain rot.

34:07

I guess it's what's going on. Um so for

34:09

those who missed it, I gave advice for

34:11

how to get your brain back in shape in a

34:12

world in which we have lots of

34:13

distractions. So obviously today's

34:15

episode

34:17

follows up on some of those ideas. I

34:18

would add the 14-day intervention we

34:20

talked about today is like idea number

34:22

six from that how to reverse brain rot

34:25

episode I did a couple weeks ago. All

34:26

right, so Emily is writing in reaction

34:28

to that episode from a couple weeks ago.

34:30

Here's what she said.

34:32

I really enjoyed your recent episode on

34:34

building cognitive fitness. I'm

34:36

currently using the composing of this

34:38

email to not avoid writing. So, thank

34:40

you for the motivation.

34:42

My question for you is also related to

34:44

this writing portion of your proposed

34:46

regimen.

34:48

My expertise is in architecture and

34:50

design, and I have found that my journal

34:52

and notebooks tend to fill with drawings

34:54

and schematics as much as with words.

34:57

Do you think that there are equivalent

34:58

alternative forms of creating,

35:00

composing, and communicating that

35:01

require the same sort of brain processes

35:04

that writing does? Or do you believe

35:05

that written language is uniquely

35:07

superior for practicing that mental

35:08

orchestration?

35:11

Well, I think exercise is a useful

35:12

analogy here, Emily, because there's

35:14

different types of exercise that can

35:16

promote fitness in different ways, all

35:18

of which is good and in general variety

35:20

is good. And I think that's what we're

35:21

talking about here.

35:23

Technical drawing and schematics are

35:25

going to work your brain in useful ways

35:27

from a cognitive fitness standpoint.

35:29

They're not the same ways that writing

35:31

works it. There's some overlap and

35:32

there's some ways where they're both

35:33

different.

35:35

So, they're both good.

35:37

In a life where you're doing some

35:38

writing and you're doing some technical

35:39

drawing and schematics, I think that's

35:41

like an athlete who cross trains.

35:43

You know, you're you're a you do a lot

35:45

of running, but now you're also doing

35:46

some cross country skiing.

35:48

There's some overlap and you're going to

35:50

get fitness in the same same sort of

35:52

fitness boost in both cases, but there's

35:54

also ways in which you're going to get

35:56

different types of fitness from each of

35:57

those. I think it's all just good.

36:00

Hard cognitive activity is good for your

36:02

brain. It's never been more important

36:03

because we're out of shape mentally.

36:05

The more you do, the better. But, I just

36:08

think fundamental

36:10

reading and writing are fundamental

36:12

activities. This is like

36:14

jogging and lightweight training. Like

36:17

you you do need that. You want that

36:18

foundation in there no matter what other

36:20

things you are doing

36:22

as well. So, I sometimes hear from

36:23

people who are like, "Well, look, I

36:24

don't write. That

36:26

I'm just not a good writer. But, I I I I

36:28

kind of fake writer. I'll use like chat

36:29

GPT and talk to it and still express

36:31

myself and and But, I do other things

36:33

that help me concentrate. And I would

36:34

say the other things are good.

36:37

But, you want that reading and writing

36:38

is like the core dynamic duo

36:42

of the post-paleolithic human modern

36:45

experience. It's where like all of the

36:47

ideas that defines modern humanity came

36:50

from. Our morality, our technology, our

36:52

politics, our philosophy.

36:55

All of those brain circuits

36:57

were forged in reading and writing.

36:59

So, you do not want to take those out of

37:00

your routine, but adding other stuff in

37:02

the routine

37:03

can only help.

37:05

All right, what do we got? Message

37:06

number three.

37:07

>> Our final message is from Tyler, but a

37:09

different Tyler than our first message.

37:11

It's about your suggestion to leave your

37:13

phone in the kitchen.

37:14

>> All Tylers today, all Tylers all the

37:16

time.

37:17

That's just a nice motto.

37:20

All right, Tyler. Thank you for what you

37:22

do. Oh, here's his message. I'm not I

37:24

mean, Tyler, thank you for what you do,

37:25

whatever that is, but I'm I'm now

37:26

reading his message.

37:28

Uh thank you for the Thank you for what

37:31

you do. Deep work and slow productivity

37:32

have been transformational in helping me

37:34

move away from distracted lazy forms of

37:36

working from home to more focused

37:39

satisfying days as a data scientist.

37:41

Deep questions help me helps me remember

37:44

why the increased cognitive effort is so

37:46

worth it.

37:47

As it's easy to get excited after

37:48

reading a book then fall back into bad

37:50

habits 2 weeks later.

37:52

My wife and I adopted leaving our phones

37:54

plugged in the kitchen as a sort of

37:56

mindfulness challenge during Lent and

37:58

couldn't believe how impactful this was

38:00

for both of us.

38:02

We now call it landlining and have

38:04

continued to practice this even after

38:06

Lent. It's easy to just tell my wife I'm

38:08

landlining, so please call if she needs

38:10

anything while she's out.

38:13

Uh I like that terminology. I think it's

38:14

useful. So, this idea of leaving your

38:15

phone plugged in the kitchen is one I

38:17

talk about all the time. I think it's

38:18

one of the easiest ways to begin to de-

38:21

de-addict your mind

38:23

from the attraction of your phone,

38:25

especially if your phone just

38:26

fundamentally has things attractive on

38:27

it, is keep it plugged in your kitchen,

38:28

so you would have to get up and go get

38:30

it if you want to use it.

38:32

Do not have it on your person while you

38:33

eat, while you watch TV, while you read

38:35

books, while you socialize with your

38:36

family. It makes such a big difference,

38:37

but I like having a term for it. So,

38:39

Tyler and his wife call it landlining.

38:42

I think that's useful because it gives

38:45

you a shorthand for explaining to people

38:48

don't expect me maybe to immediately

38:50

see, for example, a text message you

38:52

send.

38:54

That's one of the big hooks that keeps

38:55

us near the ocean, so that the jaws of

38:57

distraction can grab us and pull us

38:58

under, is this idea of

39:01

people might expect me to answer a text

39:03

message, and I I don't want to seem like

39:05

I'm being rude, so I need my phone with

39:06

me to check those text messages, and now

39:08

it's on you, now they've got you. And

39:10

all the other stuff are there.

39:11

So, if landlining caught on, you could

39:13

use it in the same way that Tyler uses

39:15

it with his wife, right? You could say,

39:18

"I'm landlining in the evening, so

39:19

you're going to have to call

39:21

uh if you have something urgent to get

39:23

my attention, right?"

39:24

So, I like that, landlining.

39:27

People should use I like the

39:28

terminology. People should use it.

39:32

All right, so uh

39:34

because it's Monday, I want to close out

39:36

by uh talking about what I am up to. I'm

39:40

actually loading something on my phone.

39:45

And Jesse,

39:47

see here. You know what I'm seeing as I

39:48

go through my phone, looking through the

39:49

photos,

39:50

um

39:51

a lot of baseball photos. It's a lot of

39:54

Little League coaching photos of

39:56

All right, what we're going to do now is

39:57

we're going to break down multiple

39:59

pitches from my son's last Little League

40:00

appearance.

40:01

That'd be a good episode of the show.

40:02

No, I was looking up a a thing, a book

40:04

title. All right, uh

40:06

I finished my fifth and final book of

40:08

May. It was actually an early release

40:10

version of a new book written by my dad

40:12

that's called how society should deal

40:14

with inequality. Um so, my dad's a

40:16

sociologist who then went on to become

40:18

the editor-in-chief of the Gallup Poll

40:20

before retiring from that role to be a

40:22

senior scientist at Gallup in 2018. He's

40:24

also currently a visiting scholar at

40:26

Stanford's Institute for Excellence in

40:28

Survey Research.

40:29

It's a cool book because

40:32

it mixes positive psychology which was

40:35

bigger a few decades ago about using

40:37

sociology to try to figure out how to

40:39

make society function better as opposed

40:41

to negative sociology which is just

40:43

about trying to highlight issues with

40:45

current society.

40:46

And as one of its core sources of

40:48

information and motivation for what is

40:50

proposed is survey research, actually

40:51

public opinion polls. So it's sort of

40:52

like a great merging of roles in which

40:55

he is a world-class expert.

40:56

I enjoyed that book. That was my 5th of

40:58

May.

41:00

And now I am I'm deep into recording

41:03

this on what the 3rd or 4th What day is

41:04

it?

41:06

>> 5th.

41:06

>> All right, I got to get rolling. I'm in

41:07

my first book of

41:09

That was my last book of April.

41:11

I'm moving slowly through my first book

41:13

in May. So I got to kind of pick up the

41:15

pace. I've been busy recently.

41:16

>> We talked about last week having

41:19

counting long longer books for multiple

41:22

books.

41:22

>> I want to try that. I definitely want to

41:23

try that. So I think what I'm going to

41:25

do So I'm I'm reading a sort of long

41:27

enough It's a long book, but it's going

41:28

to count as one. I'm also reading the

41:30

book that you got me which is short. So

41:32

I'll be able to finish that pretty

41:33

quickly. I think I want to finish three

41:35

regular books by the halfway point and

41:38

then go for a twofer.

41:40

It's like a 600-page book or something

41:42

like this to be count as the final two

41:44

books of May.

41:45

>> Yeah, I kind of as a fan I want a

41:47

twofer.

41:48

>> I want to do a twofer.

41:50

I don't know what I'm going to do.

41:52

I got some ideas.

41:53

I got to I got to be

41:55

I got some I got some ideas. There's

41:57

various constituencies in my life that

41:59

are uh

42:01

arguing for different things. My son

42:02

wants me to read more Brandon Sanderson.

42:04

Those are usually twofers. Those are

42:05

long.

42:06

>> Yeah.

42:07

>> He reads these

42:08

doorstops of books.

42:10

There's some non-fiction twofers I've

42:11

been meaning to read as well.

42:14

All right. Oh, I got one in mind. All

42:16

right, so I got to get through my three

42:17

because I really want to

42:19

I really want to dig into uh, a twofer.

42:22

And I'm building up my strength, Jesse,

42:24

for a threefer.

42:25

>> Yeah.

42:26

>> 750 pages or more.

42:28

All ca- count. So, like an 800-page book

42:30

would count as three.

42:31

>> Mhm.

42:32

>> I have some options.

42:34

But, I got to I got to get my speed up.

42:36

All right, well, that's all the time we

42:37

have

42:38

for this week. Uh, we got an AI reality

42:41

check

42:42

coming out on Thursday, and then another

42:43

advice episode on the Monday that

42:45

follows. So, hopefully I'll see you or

42:47

you'll hear me both those occasions.

42:49

Sign up for my newsletter at

42:50

calnewport.com.

42:52

And until then, as always,

42:54

stay deep.

Interactive Summary

The video discusses a research paper revealing significant improvements in mental health, sustained attention, and subjective well-being after just two weeks of blocking mobile internet on smartphones. This intervention, which involves disabling distracting internet-powered apps like social media and web browsers, led to a 50% reduction in daily screen time. The positive changes are attributed to increased engagement in meaningful offline activities, more social interaction, better sleep, and an enhanced sense of self-control. The speaker provides three practical tips for successfully implementing this digital detox: block precisely by targeting only truly distracting apps, strengthen controls to add friction to disengaging the block, and lean into boredom to encourage redirection towards beneficial activities. The long-term goal is to permanently reduce reliance on these apps. The episode also touches on the observed negative impact of AI on the quality of academic research and highlights the fundamental importance of reading and writing for cognitive fitness.
