How to spot unhealthy ideas that prevent true happiness

Consumerism is sort of like junk food—you can consume all you want but it's still never going to be filling.

Johann Hari: Of the nine causes of depression and anxiety I learned about for my book Lost Connections, there were a few that were really challenging for me because I realized how much I recognized them in myself. So one of the hardest – I have to tell you a story about something else first, but when I was, in 2009 on Christmas Eve—it makes it even sadder that this story happened on Christmas Eve. So I use to live on junk food. I used to eat appallingly.

And on Christmas Eve 2009 I went into my local KFC at lunchtime and I turned up and I gave my order—which is so disgusting I won’t even repeat it.

And the guy behind the counter said “Oh Johann, I’m so glad you’re here! Wait a minute.”

I was like, “Okay….”

So he walked off and he came back with all the other staff and they’d bought me a massive Christmas card. And they’d written in it “To our best customer.”

And so I was looking at this and my clogged heart sank. I thought, “This isn’t even the fried chicken shop I come to the most.” It was a very unfortunate low point.

But we all know, right, junk food has taken over our diets. Not admittedly to the extreme that I was, but junk food is increasingly dominating our diets and it’s making us physically sick.

One of the things that really shocked me in the research is that there’s really good evidence that something similar has happened with our minds. Our kind of junk values have taken over our minds and they’ve made us mentally sick.

So for thousands of years now philosophers have said, if you think life is about, you know, money and status and showing off you’re going to feel terrible, right? From Confucius on down, people have been warning us of that. But weirdly nobody had actually scientifically investigated it, until an incredible man I got to know called Professor Tim Kasser who’s at Knox University in Illinois.

So Professor Kasser knew when it comes to human motivation there’s basically—to put it crudely—two kinds of human motivation, right.

Imagine you play the piano. If you play the piano in the morning because you love it and it gives you joy, that’s an intrinsic motivation. You’re not doing it to get something out of it. You’re just doing it because that thing gives you joy, right?

Okay, now imagine you play the piano not because it gives you joy, but in a dive bar to pay the rent or because your parents are really pressuring you to be a piano maestro, or to impress a man, maybe some weird piano fetishist, right? That would be an extrinsic reason to play the piano. You’re not doing it for the experience itself. You’re doing it to get something out of it. You’re doing it one removed. You’re doing it to get something out of the experience.

Now we’re all a mixture of intrinsic and extrinsic values obviously, and we change throughout our lives. But Professor Kasser discovered some really fascinating things. The first thing is, the more your life is dominated by extrinsic values—the more you’re doing things not because you think they’re important but because of how you’ll look to other people, how you’ll seem on the outside—the more likely you are to become depressed and anxious. It’s a quite significant effect that’s been found in 22 studies with depression and 14 studies with anxiety.

Now there are many reasons. I’ll give you just one. One of the things we know is that something that’s a real source of joy in human life, things that really necessary are what are called flow states, right? They’re moments when you’re doing something you really love. For me it’s writing. For someone else it might be running. It’s definitely not that for me. Or, you know, whatever. When your time seems to collapse you’re totally in the moment of what you’re doing and you’re flowing, right?

Extreme extrinsic values massively disrupt your ability to get into flow states. If you imagine you’re playing the piano. Imagine the guy’s playing the piano for intrinsic reasons, right, because it gives him joy. Now imagine suddenly he has to think, “Am I the best piano player in New York City today? Who’s better than me? How are these people listening to me? How are they judging me? Am I going to get paid for this?” You can see how it would jolt you out of the flow state, right? When you think extrinsically you get jolted out of flow state. There are many reasons why extrinsic values make us feel bad and they ruin the quality of your relationships. They crowd out intrinsic values.

There’s all sorts of things going on. But Professor Kasser is also showing that extrinsic values have been taking over our culture. We’re becoming more and more dominated by these extrinsic values. We are immersed in this way of thinking from the moment we’re born. More 18-month-old children recognize the McDonald’s M than know their own surname.

We are pickled in advertising messages telling us that life is about living extrinsically, right?

Imagine an advert that told you, “You know what? You’re great. You look fine. You smell nice. You’re amazing. You don’t need anything more today.”

That would be the worst advert that had ever been done, right? Advertising is the ultimate frenemy. It’s always telling you “Oh babe, I love you. It’s just, you know, if only you didn’t stink,” right?

Now what Professor Kasser showed as he puts it is at some level we all know this; everyone watching this knows you’re not going to lie, on the last day of your life you will not lie there and think about all the things you bought, right. You will not think about all the hours you put in at the office. You will think about moments of deep meaning and connection. But as Professor Kasser puts it we live in a machine that’s constantly diverting us from what is meaningful about life.

There’s a wonderful experiment that was done before Professor Kasser’s work, but I think it really illustrates this. It was done in 1978. It’s a very simple experiment. You get a lot of five year olds and you put them in a sand pit, and you split them into two groups.

The first group is shown two advertisements for a specific toy, whatever the 1978 equivalent of Peppa Pig was, right. And the second group is shown no adverts. And at the end of it they give all the kids a choice. They say “Okay kids, got a choice now. You can either play with a nice boy who doesn’t have the toy from the advert, or you can play with a nasty boy who’s got the toy.

The kids who didn’t see the ad mostly choose the nice boy without the toy. And the kids who saw the ad mostly chose the nasty boy who’s got the toy. So just two advertisements—two—primed those children to choose an inanimate lump of plastic over kindness and connection.

We are all being driven by way more advertising than that every day, right? Anyone watching this—and I would include myself in that—who stayed late at work doing something they don’t want to do to buy something they don’t need rather than… go be home with their kids maybe? You’ve fallen prey to that dynamic.

And Professor Kasser has really shown this way that we’ve got to unpick these junk values. These junk values are what we’ve been fed for so long. They’re a kind of KFC for the soul, and they’re making us feel terrible.

  • Author and journalist Johann Hari thinks that modern life sets you up to be depressed.
  • The constant insecurity we get from heavy marketing ruins true human connections, and doesn't lead to any growth for society as a whole.
  • But there's hope.

Does conscious AI deserve rights?

If machines develop consciousness, or if we manage to give it to them, the human-robot dynamic will forever be different.

  • Does AI—and, more specifically, conscious AI—deserve moral rights? In this thought exploration, evolutionary biologist Richard Dawkins, ethics and tech professor Joanna Bryson, philosopher and cognitive scientist Susan Schneider, physicist Max Tegmark, philosopher Peter Singer, and bioethicist Glenn Cohen all weigh in on the question of AI rights.
  • Given the grave tragedy of slavery throughout human history, philosophers and technologists must answer this question ahead of technological development to avoid humanity creating a slave class of conscious beings.
  • One potential safeguard against that? Regulation. Once we define the context in which AI requires rights, the simplest solution may be to not build that thing.

Hints of the 4th dimension have been detected by physicists

Physicists have understood at least theoretically, that there may be higher dimensions, besides our normal three. The first clue came in 1905 when Einstein developed his theory of special relativity. Of course, by dimensions we’re talking about length, width, and height. Generally speaking, when we talk about a fourth dimension, it’s considered space-time. But here, physicists mean a spatial dimension beyond the normal three, not a parallel universe, as such dimensions are mistaken for in popular sci-fi shows.

Predicting PTSD symptoms becomes possible with a new test

An algorithm may allow doctors to assess PTSD candidates for early intervention after traumatic ER visits.

Technology & Innovation
  • 10-15% of people visiting emergency rooms eventually develop symptoms of long-lasting PTSD.
  • Early treatment is available but there's been no way to tell who needs it.
  • Using clinical data already being collected, machine learning can identify who's at risk.

The psychological scars a traumatic experience can leave behind may have a more profound effect on a person than the original traumatic experience. Long after an acute emergency is resolved, victims of post-traumatic stress disorder (PTSD) continue to suffer its consequences.

In the U.S. some 30 million patients are annually treated in emergency departments (EDs) for a range of traumatic injuries. Add to that urgent admissions to the ED with the onset of COVID-19 symptoms. Health experts predict that some 10 percent to 15 percent of these people will develop long-lasting PTSD within a year of the initial incident. While there are interventions that can help individuals avoid PTSD, there's been no reliable way to identify those most likely to need it.

That may now have changed. A multi-disciplinary team of researchers has developed a method for predicting who is most likely to develop PTSD after a traumatic emergency-room experience. Their study is published in the journal Nature Medicine.

70 data points and machine learning

Study lead author Katharina Schultebraucks of Columbia University's Department Vagelos College of Physicians and Surgeons says:

"For many trauma patients, the ED visit is often their sole contact with the health care system. The time immediately after a traumatic injury is a critical window for identifying people at risk for PTSD and arranging appropriate follow-up treatment. The earlier we can treat those at risk, the better the likely outcomes."

The new PTSD test uses machine learning and 70 clinical data points plus a clinical stress-level assessment to develop a PTSD score for an individual that identifies their risk of acquiring the condition.

Among the 70 data points are stress hormone levels, inflammatory signals, high blood pressure, and an anxiety-level assessment. Says Schultebraucks, "We selected measures that are routinely collected in the ED and logged in the electronic medical record, plus answers to a few short questions about the psychological stress response. The idea was to create a tool that would be universally available and would add little burden to ED personnel."

Researchers used data from adult trauma survivors in Atlanta, Georgia (377 individuals) and New York City (221 individuals) to test their system.

Of this cohort, 90 percent of those predicted to be at high risk developed long-lasting PTSD symptoms within a year of the initial traumatic event — just 5 percent of people who never developed PTSD symptoms had been erroneously identified as being at risk.

On the other side of the coin, 29 percent of individuals were 'false negatives," tagged by the algorithm as not being at risk of PTSD, but then developing symptoms.

Going forward

Schultebraucks looks forward to more testing as the researchers continue to refine their algorithm and to instill confidence in the approach among ED clinicians: "Because previous models for predicting PTSD risk have not been validated in independent samples like our model, they haven't been adopted in clinical practice." She expects that, "Testing and validation of our model in larger samples will be necessary for the algorithm to be ready-to-use in the general population."

"Currently only 7% of level-1 trauma centers routinely screen for PTSD," notes Schultebraucks. "We hope that the algorithm will provide ED clinicians with a rapid, automatic readout that they could use for discharge planning and the prevention of PTSD." She envisions the algorithm being implemented in the future as a feature of electronic medical records.

The researchers also plan to test their algorithm at predicting PTSD in people whose traumatic experiences come in the form of health events such as heart attacks and strokes, as opposed to visits to the emergency department.
