How Instagram Hacks Your Brain

00:00

Hi. I’m Hank Green and I’m  addicted to social media.

00:03

Or maybe I have a social media use disorder.

00:06

Whatever you call it, my relationship  with social media is not positive.

00:10

And, yes, social media is addictive.

00:13

But like any addiction, it’s not my fault.

00:16

Social media is designed to  hack my internal reward system

00:20

and get me to check in pretty much constantly.

00:22

Researchers know that social media

00:24

and our brains have a messy relationship.

00:26

But if you can stay away from it  long enough to watch this video,

00:29

you’ll at least know how that relationship works

00:32

and how those researchers  suggest we can improve it.

00:35

[intro music]

00:38

When I post something on Instagram,  YouTube, or even LinkedIn,

00:42

I’ll admit I’m chasing that high  of the all important “like.”

00:47

The human brain loves “likes”

00:49

because they activate the same pathways

00:51

as seeing money hit your bank on pay day

00:54

and hearing a compliment from a friend.

00:55

It feels good to get people’s tiny digital hearts,

00:59

or thumbs up…or whatever they use on LinkedIn.

01:02

But likes aren’t a one way street.

01:03

It turns out when you give  someone else’s post a like,

01:06

that also activates some of the same brain bits.

01:10

This is according to a study published in 2018,

01:12

which featured 58 young people  getting their brains scanned

01:16

by an MRI machine

01:17

while they participated in  a social media experiment.

01:20

To help control this experiment,

01:22

the researchers designed a sort  of fake version of Instagram

01:25

for the participants to use.

01:27

While inside the MRI,

01:29

participants scrolled and liked photos at will.

01:32

Then after they got out, they  rated the photos they had just seen

01:35

on a 7-point scale.

01:37

Once the researchers did all their fancy stats,

01:39

they were able to show that if you  take an MRI image of someone’s brain…

01:43

and know that someone is looking  at a picture on fake Instagram…

01:47

urately predict how much they  actually like that picture.

01:51

So there’s some defined neural activity  associated with liking Instagram photos.

01:56

And this activity is similar to  what we know happens in your brain

02:00

when you engage in other rewarding behaviors,

02:02

like accomplishing a goal or  eating your favorite snack.

02:05

But social media can have more power  than merely tickling your reward centers.

02:09

The way you engage with it can also  change your brain’s reward pathways

02:13

in addictive ways.

02:15

It’s called Social Networking Site addiction,

02:17

and it involves dependence,  withdrawal, relapse, tolerance,

02:21

and other addictive responses.

02:23

People who are addicted to social  media obsessively use these sites

02:26

to the point that it gets in the  way of the rest of their lives.

02:29

It has a lot in common with other addictions,

02:31

although you might not have heard of it,

02:32

in part because not all experts agree it’s a thing.

02:35

But a solid portion of them use this terminology,
