Social Media's Dark Side: How Connectivity Uprooted Our Self-Worth

We used to use technology. Now technology uses us. Silicon Valley ethicist Tristan Harris explains how the attention economy hijacked our self-worth for profit.

Tristan Harris: Well, there's a really common misconception that technology is neutral and it's up to us to just choose how to use it.

And so we're sitting there and we're scrolling and we find ourselves in this kind of wormhole and then we say, “Oh man, like, I should really have more self-control." And that's partially true, but what we forget when we talk about it that way is that there's a thousand engineers on the other side of the screen whose job it was to get my finger to do that the next time. And there's this whole playbook of techniques that they use to get us to keep using the software more.

Was design always this manipulative? It wasn't always this way. In fact, back in the 1970s and the early '80s at Xerox PARC when Steve Jobs first went over and saw the graphical user interface, the way people talked about computers and what computers were supposed to be was a “bicycle for our minds” that, here we are, you take a human being and they have a certain set of capacities and capabilities, and then you give them a bicycle and they can go to all these new distances, they're empowered to go to these brand-new places and to do these new things, to have these new capacities.

And that's always been the philosophy of people who make technology: how do we create bicycles for our minds to do and empower us to feel and access more?

Now, when the first iPhone was introduced it was also the philosophy of the technology; how do we empower people to do something more? And in those days it wasn't manipulative because there was no competition for attention. Photoshop wasn't trying to maximize how much attention it took from you—it didn't measure its success that way.

And the Internet overall had been, in the very beginning, not designed to maximize attention, it was just putting things out there, putting things out there, creating these message boards.
It wasn't designed with this whole persuasive psychology that emerged later. What happened is that the attention economy and this race for attention got more and more competitive, and the more competitive it got to get people's attention on, let's say a news website, the more they need to add these design principles, these more manipulative design tactics as ways of holding onto your attention.

And so YouTube goes from being a more neutral, honest tool of just, “Here's a video,” to, “Oh, do you want to see these other videos? And do you want to auto-play the next video? And here's some notifications…”

These products start to look and feel more like media that's about maximizing consumption and less like bicycles for our minds.

And I think that's such a subtle an important thing to recognize, is that more and more of technology is really not on our team to help us spend our time the way we want to, it's more on the team of maximizing how much time we spend on the screen.

Right now, the only way to succeed in the app store is by proving you're really good at getting people's attention. And so by making attention the currency of success it forces all of these good-hearted, good-intentioned people who make apps or make media sites, to do things they don't want to do just because they have to get attention. You have mediation apps that have to send you all thee notifications and add streaks and do all this game-y stuff just to get you to use it the most, as opposed to having the phone itself recognize that there's parts of your life where mediation might want to be at the top of the list for you, because you're defining that, and so that meditation app could win for the right reasons, not for the wrong reasons.

So we always worry about new technologies when they first appear. When people started bringing out the newspapers on the subway people worried, “Oh my god, people are going to stop talking to each other on the subway!” And then TV showed up and people worried, “Oh my god, people are going to spend all this time at home!” And the radio—we always worry, and then somehow it seems to turn out okay. Back in the 1970s people were at home on the telephone and calling each other all the time, we thought, “Oh the kids these days, what are they doing to their minds?” So now it's tempting to say, “Well now the kids these days they're on Snapchat, and therefore we survived all those other technology transitions, nothing really bad happened, so maybe it's all okay, this is just kids being kids in a new way.” And I want to talk about why that's not true and why this is different.

What's different is that, let's say—let's take that telephone example: in the 1970s if someone picked up a telephone to go call their friend and they spent time gossiping on the telephone, we could do that, that's fine. But the telephone wasn't updated every day with new manipulative design principles to be better and better at seducing you into calling your friends.

So what's different with Snapchat is that there are a thousand engineers every single day who work on the product to actually find new ways not to just get you to use it but to kind of tap you both on the shoulder and try to get you into a reciprocity relationship where you owe someone else a response. In fact they have a feature in Snapchat called Snapstreaks. And Snapstreaks count the number of days in a row you've sent a message back-and-forth with someone. So if I have a best friend and we've been chatting every day for a hundred days I see a little fireball and the number 100 next to it. And what that does is, they've just created something now I don't want to lose because I have a streak going, I've got a hundred days and now if I don't send them a message tomorrow I'm going to lose the whole thing.

And when you're a kid actually this has a really big impact on you. I'm not making this up. There's a woman named Emily Weinstein at Harvard who studied the effects of Snapchat and Snapstreaks on kids by accident—it emerged in her interviews.

And she found out that kids, when they go on vacation they have to give their password to up to five other friends to actually have them send messages while they're gone on vacation because they're so worried about losing their Snapstreaks. In fact a lot of kids, they wake up and they see these 30 contacts with different streaks and they have to just take pictures of floors and ceilings just to kind of get through all these Snapstreaks so they don't lose any of them.
So we have to ask, when Snapchat is designing a feature like Snapstreaks, are they doing that because they most want to help kids empower them to live their lives or are they doing that because it's really good at getting their attention?

And when we're parents and we see kids using it this way we have to recognize there's something very different going on here. This was not true in the 1970s when we had a neutral telephone that we would choose to use when we wanted to use it. There are now a thousand people behind our new telephone, which is say, Snapchat, that's being designed and updated every day to be more compelling at addicting and holding onto people's attention. And it's not good for us.

I think we can all feel it. We become more and more on the treadmill to the number of likes or feedback we get, basically, from social media and start tying our own approval, our own self-worth to how much attention we get from other people. I mean, even for me I notice that if I post something it does affect me whether or not I have a lot of likes or few likes.
And it's hard to really, if you think about it and get to the sense of, “My self-worth is completely independent of that.” That's a subtle thing to hold and developmentally, children are more vulnerable to their self-worth being externalized like this.

And the problem is that there's always been, as well, ways of externalizing our self-worth in terms of how much money we have in our bank account or in terms of how many friends we have, but now the externalization of our self-worth is controlled by a handful of companies whose goals are different than our goals.

They're not evil companies, they just have the different goal of maximizing attention, and our goals are not that. But the problem is that their goals become our goals. This is what's actually so dangerous, is that their goals of engaging us the most by having us care about likes become our goals. We actually wake up in the morning as a sovereign human beings and we start caring about the number of likes we got, as if that's our goal in life. That becomes our goal. And it's as if we've been infected, it's as if they've drilled a hole in the back of our head and now they've injected the virus and now we walk around searching for feedback using social media. And they won, if that happens.

And again, it's not because they're evil but they're in a different game, they're trying to maximize attention. But we have to ask a much deeper question, which is: what do we want in our lives and what is our self-worth actually tied to? And maybe it's being virtuous or being a good friend or caring about what matters or living by our values.

There's a whole bunch of things that we can define for ourselves, and I think the less people have to find their own values the more vulnerable they are to someone else coming in and giving them their values. And to fix that we're going to need to talk about different kinds of metrics, different ways of measuring success and monetizing success. So instead of making more money the more time we get, we instead make more money the more we've helped you in your life.

In the 1970s, at the dawn of personal computers, people like Steve Jobs and the scientists at Xerox PARC talked about computers as "bicycles for our mind". Sure, someone was going to make big money selling these hardware units, but the intention was at heart quite pure; computers would give our minds wheels to go farther than ever before. Our capabilities would be augmented by technology, and we would become smarter and more capable. That ethos has not really stuck, and today we find ourselves in a Pavlovian relationship with push notifications, incapacitated by the multi-directional pull on our attention spans.

We've made it through every new technological wave—newspapers, radio, TV, laptops, cell phones—without the social decay that was widely prophesied, but there's something different about smartphones loaded with apps living in the palm of our hand, says tech ethicist Tristan Harris. It would be a mistake not to recognize how, this time, it really is different. Companies today are not more evil than they were in the 1970s, what's changed is the environment they operate in: the attention economy, where the currency is your eyeballs on their product, for as long as possible—precious exposure that can be sold to advertisers. Unlike the neutral technology we once used, and could walk away from, today's technology uses us. Behind every app—Facebook, Twitter, Snapchat—are 1,000 software designers working every day to update and find new psychological levers to keep you hooked to this product. The most powerful development has been that of 'likes', public feedback that externalized our self-worth onto a score card (this has reached new heights with Snapchat's streaks, which research by Emily Weinstein at Harvard has shown puts extreme stress on kids and adolescents.) "These products start to look and feel more like media that's about maximizing consumption and less like bicycles for our minds," says Harris. Is it too late to do something about the attention economy? To find out more about Tristan Harris, head to

How accountability at work can transform your organization

If you don't practice accountability at work you're letting the formula for success slip right through your hands.

  • What is accountability? It's a tool for improving performance and, once its potential is thoroughly understood, it can be leveraged at scale in any team or organization.
  • In this lesson for leaders, managers, and individuals, Shideh Sedgh Bina, a founding partner of Insigniam and the editor-in-chief of IQ Insigniam Quarterly, explains why it is so crucial to success.
  • Learn to recognize the mindset of accountable versus unaccountable people, then use Shideh's guided exercise as a template for your next post-project accountability analysis—whether that project was a success or it fell short, it's equally important to do the reckoning.

A massive star has mysteriously vanished, confusing astronomers

A gigantic star makes off during an eight-year gap in observations.

Image source: ESO/L. Calçada
Surprising Science
  • The massive star in the Kinsman Dwarf Galaxy seems to have disappeared between 2011 and 2019.
  • It's likely that it erupted, but could it have collapsed into a black hole without a supernova?
  • Maybe it's still there, but much less luminous and/or covered by dust.

A "very massive star" in the Kinman Dwarf galaxy caught the attention of astronomers in the early years of the 2000s: It seemed to be reaching a late-ish chapter in its life story and offered a rare chance to observe the death of a large star in a region low in metallicity. However, by the time scientists had the chance to turn the European Southern Observatory's (ESO) Very Large Telescope (VLT) in Paranal, Chile back around to it in 2019 — it's not a slow-turner, just an in-demand device — it was utterly gone without a trace. But how?

The two leading theories about what happened are that either it's still there, still erupting its way through its death throes, with less luminosity and perhaps obscured by dust, or it just up and collapsed into a black hole without going through a supernova stage. "If true, this would be the first direct detection of such a monster star ending its life in this manner," says Andrew Allan of Trinity College Dublin, Ireland, leader of the observation team whose study is published in Monthly Notices of the Royal Astronomical Society.

So, em...

Between astronomers' last look in 2011 and 2019 is a large enough interval of time for something to happen. Not that 2001 (when it was first observed) or 2019 have much meaning, since we're always watching the past out there and the Kinman Dwarf Galaxy is 75 million light years away. We often think of cosmic events as slow-moving phenomena because so often their follow-on effects are massive and unfold to us over time. But things happen just as fast big as small. The number of things that happened in the first 10 millionth of a trillionth of a trillionth of a trillionth of a second after the Big Bang, for example, is insane.

In any event, the Kinsman Dwarf Galaxy, or PHL 293B, is far way, too far for astronomers to directly observe its stars. Their presence can be inferred from spectroscopic signatures — specifically, PHL 293B between 2001 and 2011 consistently featured strong signatures of hydrogen that indicated the presence of a massive "luminous blue variable" (LBV) star about 2.5 times more brilliant than our Sun. Astronomers suspect that some very large stars may spend their final years as LBVs.

Though LBVs are known to experience radical shifts in spectra and brightness, they reliably leave specific traces that help confirm their ongoing presence. In 2019 the hydrogen signatures, and such traces, were gone. Allan says, "It would be highly unusual for such a massive star to disappear without producing a bright supernova explosion."

The Kinsman Dwarf Galaxy, or PHL 293B, is one of the most metal-poor galaxies known. Explosive, massive, Wolf-Rayet stars are seldom seen in such environments — NASA refers to such stars as those that "live fast, die hard." Red supergiants are also rare to low Z environments. The now-missing star was looked to as a rare opportunity to observe a massive star's late stages in such an environment.

Celestial sleuthing

In August 2019, the team pointed the four eight-meter telescopes of ESO's ESPRESSO array simultaneously toward the LBV's former location: nothing. They also gave the VLT's X-shooter instrument a shot a few months later: also nothing.

Still pursuing the missing star, the scientists acquired access to older data for comparison to what they already felt they knew. "The ESO Science Archive Facility enabled us to find and use data of the same object obtained in 2002 and 2009," says Andrea Mehner, an ESO staff member who worked on the study. "The comparison of the 2002 high-resolution UVES spectra with our observations obtained in 2019 with ESO's newest high-resolution spectrograph ESPRESSO was especially revealing, from both an astronomical and an instrumentation point of view."

Examination of this data suggested that the LBV may have indeed been winding up to a grand final sometime after 2011.

Team member Jose Groh, also of Trinity College, says "We may have detected one of the most massive stars of the local Universe going gently into the night. Our discovery would not have been made without using the powerful ESO 8-meter telescopes, their unique instrumentation, and the prompt access to those capabilities following the recent agreement of Ireland to join ESO."

Combining the 2019 data with contemporaneous Hubble Space Telescope (HST) imagery leaves the authors of the reports with the sense that "the LBV was in an eruptive state at least between 2001 and 2011, which then ended, and may have been followed by a collapse into a massive BH without the production of an SN. This scenario is consistent with the available HST and ground-based photometry."


A star collapsing into a black hole without a supernova would be a rare event, and that argues against the idea. The paper also notes that we may simply have missed the star's supernova during the eight-year observation gap.

LBVs are known to be highly unstable, so the star dropping to a state of less luminosity or producing a dust cover would be much more in the realm of expected behavior.

Says the paper: "A combination of a slightly reduced luminosity and a thick dusty shell could result in the star being obscured. While the lack of variability between the 2009 and 2019 near-infrared continuum from our X-shooter spectra eliminates the possibility of formation of hot dust (⪆1500 K), mid-infrared observations are necessary to rule out a slowly expanding cooler dust shell."

The authors of the report are pretty confident the star experienced a dramatic eruption after 2011. Beyond that, though:

"Based on our observations and models, we suggest that PHL 293B hosted an LBV with an eruption that ended sometime after 2011. This could have been followed by
(1) a surviving star or
(2) a collapse of the LBV to a BH [black hole] without the production of a bright SN, but possibly with a weak transient."

NASA releases first sounds ever captured on Mars

On Friday, NASA's InSight Mars lander captured and transmitted historic audio from the red planet.

Surprising Science
  • The audio captured by the lander is of Martian winds blowing at an estimated 10 to 15 mph.
  • It was taken by the InSight Mars lander, which is designed to help scientists learn more about the formation of rocky planets, and possibly discover liquid water on Mars.
  • Microphones are essentially an "extra sense" that scientists can use during experiments on other planets.

Changing the way we grade students could trigger a wave of innovation

How students apply what they've learned is more important than a letter or number grade.

Future of Learning
  • Schools are places where learning happens, but how much of what students learn there matters? "Almost all of our learning happens through experience and very little of it actually happens in these kinds of organized, contrived, constrained environments," argues Will Richardson, co-founder of The Big Questions Institute and one of the world's leading edupreneurs.
  • There is a shift starting, Richardson says, in terms of how we look at grading and assessments and how they have traditionally dictated students' futures. Consortiums like are pushing back on the idea that what students know can be reflected in numbers and letter grades.
  • One of the crucial steps in changing how things are done is first changing the narratives. Students should be assessed on how they can apply what they've learned, not scored based on what they know.
