Why flat-Earth theory and anti-vax conspiracies exist

Humans are hardwired to believe in nonsense, says Michio Kaku. So what can we do about it?

MICHIO KAKU: We still have Flat Earthers, we have people that don't believe in vaccinations, and what do we do about it? Well, first of all, I think there's a gene. I think there's a gene for superstition, a gene for hearsay, a gene for magic, a gene for magical thinking. And I think that, when we were in the forest, that gene actually helped us. Because 9 times out of 10, that gene was wrong. Superstition didn't work. But 1 time out of 10, it saved your butt. That's why the gene is still here, the gene for superstition and magic.

Now, there's no gene for science. Science is based on things that are reproducible, testable -- it's a long process, the scientific method. It's not part of our natural thinking. It's an acquired taste, just like broccoli. You have to learn how the power can be unleashed by looking at your diet, for example. So I think 1,000 years from now, 1,000 years from now, we will have Flat Earthers. A thousand years from now, we will have people that still do not want to be vaccinated. OK? So what do we do about it?

Well, it's a struggle. It's a struggle that's eternal, because I think it's part of our genetic makeup. And there's even a name for some of this superstition. It's called pareidolia. What is pareidolia? It's the idea that when you look in the sky, you see things that are not there. Here's one experiment: Look at the clouds and try not to see something there. It's very difficult. You look at the clouds. You can't help it. You see Donald Duck. You see Mickey Mouse. You see snakes, animals. You see all sorts of stuff. You can't help it. Recently, the Notre Dame Cathedral partially burned down. And sure enough, somebody said, 'I see Jesus Christ there.' I saw the picture. Maybe you did, too. It really did look like Jesus Christ. But it was the ashes of Notre Dame. And how many times do people see the Virgin Mary in a glass of tea? So we are hardwired to see things that are not there. Because for the most part, they're harmless. For the most part, they do nothing. And once in a while, it saves our butt.

And so that's why I think we will have Flat Earthers, we will have the people who don't like vaccination, because hearsay throughout human history was the dominant form of information-sharing. You know, the internet is very new. Newspapers are very new. Science and technology is very new. But gossip, hearsay, slander, rumors, there's a gene for that. OK? So how do you combat it? Slowly, carefully, painfully -- it's a painful process, but in some sense, we're going up against our genetic predisposition to believe in nonsense.

  • If you see animals when you look at clouds or see faces in pieces of wood, that's called pareidolia: the phenomenon of making familiar objects from vague stimuli.
  • Humans evolved to be superstitious, and Michio Kaku posits that there is a gene for superstition and magical thinking. Nine times out of 10, your beliefs can be wrong, but one time out of 10 it saved your ancestors' butts, says Kaku.
  • Flat Earthers and anti-vaccination conspiracy theorists exist now, and they will still exist in 1,000 years, says Kaku. It's natural. Humans evolved to believe in nonsense, but it's by becoming good at something totally unnatural to us – science – that reason can prevail.


Are we really addicted to technology?

Fear that new technologies are addictive isn't a modern phenomenon.

In many ways, technology has made our lives better. Through smartphones, apps, and social media platforms we can now work more efficiently and connect in ways that would have been unimaginable just decades ago.

But as we've grown to rely on technology for a lot of our professional and personal needs, most of us are asking tough questions about the role technology plays in our own lives. Are we becoming too dependent on technology to the point that it's actually harming us?

In the latest episode of Build for Tomorrow, host and Entrepreneur Editor-in-Chief Jason Feifer takes on the thorny question: is technology addictive?

Popularizing medical language

What makes something addictive rather than just engaging? It's a meaningful distinction because if technology is addictive, the next question could be: are the creators of popular digital technologies, like smartphones and social media apps, intentionally creating things that are addictive? If so, should they be held responsible?

To answer those questions, we've first got to agree on a definition of "addiction." As it turns out, that's not quite as easy as it sounds.

If we don't have a good definition of what we're talking about, then we can't properly help people.

LIAM SATCHELL UNIVERSITY OF WINCHESTER

"Over the past few decades, a lot of effort has gone into destigmatizing conversations about mental health, which of course is a very good thing," Feifer explains. It also means that medical language has entered into our vernacular —we're now more comfortable using clinical words outside of a specific diagnosis.

"We've all got that one friend who says, 'Oh, I'm a little bit OCD' or that friend who says, 'Oh, this is my big PTSD moment,'" Liam Satchell, a lecturer in psychology at the University of Winchester and guest on the podcast, says. He's concerned about how the word "addiction" gets tossed around by people with no background in mental health. An increased concern surrounding "tech addiction" isn't actually being driven by concern among psychiatric professionals, he says.

"These sorts of concerns about things like internet use or social media use haven't come from the psychiatric community as much," Satchell says. "They've come from people who are interested in technology first."

The casual use of medical language can lead to confusion about what is actually a mental health concern. We need a reliable standard for recognizing, discussing, and ultimately treating psychological conditions.

"If we don't have a good definition of what we're talking about, then we can't properly help people," Satchell says. That's why, according to Satchell, the psychiatric definition of addiction being based around experiencing distress or significant family, social, or occupational disruption needs to be included in any definition of addiction we may use.

Too much reading causes... heat rashes?

But as Feifer points out in his podcast, both popularizing medical language and the fear that new technologies are addictive aren't totally modern phenomena.

Take, for instance, the concept of "reading mania."

In the 18th Century, an author named J. G. Heinzmann claimed that people who read too many novels could experience something called "reading mania." This condition, Heinzmann explained, could cause many symptoms, including: "weakening of the eyes, heat rashes, gout, arthritis, hemorrhoids, asthma, apoplexy, pulmonary disease, indigestion, blocking of the bowels, nervous disorder, migraines, epilepsy, hypochondria, and melancholy."

"That is all very specific! But really, even the term 'reading mania' is medical," Feifer says.

"Manic episodes are not a joke, folks. But this didn't stop people a century later from applying the same term to wristwatches."

Indeed, an 1889 piece in the Newcastle Weekly Courant declared: "The watch mania, as it is called, is certainly excessive; indeed it becomes rabid."

Similar concerns have echoed throughout history about the radio, telephone, TV, and video games.

"It may sound comical in our modern context, but back then, when those new technologies were the latest distraction, they were probably really engaging. People spent too much time doing them," Feifer says. "And what can we say about that now, having seen it play out over and over and over again? We can say it's common. It's a common behavior. Doesn't mean it's the healthiest one. It's just not a medical problem."

Few today would argue that novels are in-and-of-themselves addictive — regardless of how voraciously you may have consumed your last favorite novel. So, what happened? Were these things ever addictive — and if not, what was happening in these moments of concern?

People are complicated, our relationship with new technology is complicated, and addiction is complicated — and our efforts to simplify very complex things, and make generalizations across broad portions of the population, can lead to real harm.

JASON FEIFER HOST OF BUILD FOR TOMORROW

There's a risk of pathologizing normal behavior, says Joel Billieux, professor of clinical psychology and psychological assessment at the University of Lausanne in Switzerland, and guest on the podcast. He's on a mission to understand how we can suss out what is truly addictive behavior versus what is normal behavior that we're calling addictive.

For Billieux and other professionals, this isn't just a rhetorical game. He uses the example of gaming addiction, which has come under increased scrutiny over the past half-decade. The language used around the subject of gaming addiction will determine how behaviors of potential patients are analyzed — and ultimately what treatment is recommended.

"For a lot of people you can realize that the gaming is actually a coping (mechanism for) social anxiety or trauma or depression," says Billieux.

"Those cases, of course, you will not necessarily target gaming per se. You will target what caused depression. And then as a result, If you succeed, gaming will diminish."

In some instances, a person might legitimately be addicted to gaming or technology, and require the corresponding treatment — but that treatment might be the wrong answer for another person.

"None of this is to discount that for some people, technology is a factor in a mental health problem," says Feifer.

"I am also not discounting that individual people can use technology such as smartphones or social media to a degree where it has a genuine negative impact on their lives. But the point here to understand is that people are complicated, our relationship with new technology is complicated, and addiction is complicated — and our efforts to simplify very complex things, and make generalizations across broad portions of the population, can lead to real harm."

Behavioral addiction is a notoriously complex thing for professionals to diagnose — even more so since the latest edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the book professionals use to classify mental disorders, introduced a new idea about addiction in 2013.

"The DSM-5 grouped substance addiction with gambling addiction — this is the first time that substance addiction was directly categorized with any kind of behavioral addiction," Feifer says.

"And then, the DSM-5 went a tiny bit further — and proposed that other potentially addictive behaviors require further study."

This might not sound like that big of a deal to laypeople, but its effect was massive in medicine.

"Researchers started launching studies — not to see if a behavior like social media use can be addictive, but rather, to start with the assumption that social media use is addictive, and then to see how many people have the addiction," says Feifer.

Learned helplessness

The assumption that a lot of us are addicted to technology may itself be harming us by undermining our autonomy and belief that we have agency to create change in our own lives. That's what Nir Eyal, author of the books Hooked and Indistractable, calls 'learned helplessness.'

"The price of living in a world with so many good things in it is that sometimes we have to learn these new skills, these new behaviors to moderate our use," Eyal says. "One surefire way to not do anything is to believe you are powerless. That's what learned helplessness is all about."

So if it's not an addiction that most of us are experiencing when we check our phones 90 times a day or are wondering about what our followers are saying on Twitter — then what is it?

"A choice, a willful choice, and perhaps some people would not agree or would criticize your choices. But I think we cannot consider that as something that is pathological in the clinical sense," says Billieux.

Of course, for some people technology can be addictive.

"If something is genuinely interfering with your social or occupational life, and you have no ability to control it, then please seek help," says Feifer.

But for the vast majority of people, thinking about our use of technology as a choice — albeit not always a healthy one — can be the first step to overcoming unwanted habits.
