but I'm not alone.

Over 2.5 billion people have smartphones now, and a lot of them are having a hard time putting them down.

There's a new app that aims to curb phone addiction.

Addiction is money.

Are we a nation of smartphone addicts?The problem is, our devices are designed to keep us engaged.

They're intentionally addicting.

But if you understand the tricks that grab your attention, you can learn to have a healthier relationship with your phone.

I think we're living inside of two billion Truman Shows.

Where, you know, Truman Show, you wake up and everything is sort of coordinated just for you.

And you really don't even realize it, but it's coordinating just to entertain you, or just to engage you.

That's Tristan Harris, he worked as Google's design ethicist, and now he runs a nonprofit initiative called Time Well Spent, advocating for awareness of how tech companies profit off of users' attention.

It's not designed to help us, it's just designed to keep us hooked.

So I handed him my phone and asked him how he'd fix it.

It starts with turning off all notifications, except for when a real human is trying to reach you.

When you get a call, a text, or a message, it's usually because another person wants to communicate with you, but a lot of today's apps simulate the feeling of that kind of social interaction, to get you to spend more time on their platform.

If Facebook sends you a push notification that a friend is interested in an event near you, they're essentially acting like a puppet master, leveraging your desire for social connections so that you use the app more.

But notifications didn't always work like this.

When push notifications were first introduced for email on Blackberries in 2003, they were actually seen as a way for you to check your phone less.

You could easily see emails as they came in, so you didn't have to repeatedly open your phone to refresh an inbox.

But today you can get notifications from any app on your phone.

So, every time you check it, you get this grab bag of notifications that can make you feel a broad variety of emotions.

If it wasn't for random, if it was predictably bad or predictably good, then you would not get addicted.

The predictability would take out the addictiveness.

And, it's effective.

Slot machines make more money in the US than baseball, movies, and theme parks combined and they become addicting about 3-4 times faster than other kinds of gambling.

Some apps even replicate the process of pulling a slot machine lever with the "pull to refresh" feature.

That's a conscious design choice.

Those apps are usually capable of continuously updating content, but the pull action provides an addicting illusion of control over that process.

In the future, we might see healthier ways of delivering notifications.

Research shows that bundling notifications, where phones deliver a batch of updates at set times, reduces user stress.

Then, you have to grayscale your screen.

The easiest way to attract your eye's attention on a screen is through color.

Human eyes are sensitive to warm colors.

In eye-tracking tests like this one, they gravitate particularly to bright red.

That's why so many apps have redesigned their icons to be brighter, bolder, and warmer over the years.

It's also why notification bubbles are red.

A little icon like this, or this, doesn't have the same impact on your attention as this.

But you can neutralize that distracting effect by selecting a greyscale color filter in your phone's accessibility settings.

When you make everything black and white, your brain isn't tricked into thinking that this is any more important to you than this.

I mean, there's a reason why slot machines are bright and color and flashing lights and ding ding ding ding ding.

They have the sensory input too, right.

And so, just noticing that if I take out the color, it changes some of the addictiveness.

Finally, restrict your home screen to everyday tools.

Make sure that your home screen, when you unlock it, doesn't have anything except for the in-the-moment tools that help you live your life.

I have Lyft, to get somewhere when I need to get somewhere, Maps, Calendar.

None of these are apps that I can fall into and then get sucked down some bottomless vortex of stuff.

If you're not sure what counts as a bottomless vortex of stuff, it helps to filter out apps that use infinite scrolling.

Unlike pagination, where users have to click to load new content on another page, infinite scrolling continuously loads new material so there's no built-in endpoint.

Video autoplay works in a similar way.

These interfaces create a frictionless experience, but they also create a user's sense of control and make it harder to stop.

Research shows that people rely on visual cues more than internal cues to stop consuming something.

In a 2005 study, individuals who ate soup out of a self-refilling bowl, ate 73% more than those who ate out of a normal bowl filled up by servers.

But those who ate from the self-refilling bowl, didn't feel any more satisfied.

So, a visual cue, like an endpoint, is better at telling you the right time to stop than your own sense of satisfaction.

And because so many apps don't have an endpoint, you have to build your home screen around the eventuality of distraction.

We check our phones a lot.

Most of us drastically underestimate how often we do so.

But technology might not always look this way.

There are ideas for alternative interfaces that give you functional choices and are more transparent about how much time you'll lose with one action, versus another.

But it's a really deep philosophical question: what is genuinely worth your attention?

On an interruptive basis?

Do people even know how to answer that question?

It's a really hard question, it's not something we think about.

But, for now, it's a question that everybody needs to start asking.

Thank you so much for watching, this has been episode 1 of By Design, this is gonna be a new series looking at different topics in design, in technology, looking at how human decisions on one end of creating something affect people on the other end.

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
