the psychological tendency to favor information that confirms our beliefs

If this explanation is right, then there is a relatively straightforward solution to political polarization: We need to consciously expose ourselves to evidence that challenges our beliefs to compensate for our inclination to discount it.

But what if confirmation bias isn’t the only culprit? It recently struck us that confirmation bias is often conflated with “telling people what they want to hear,” which is actually a distinct phenomenon known as desirability bias, or the tendency to credit information you want to believe.

we decided to conduct an experiment that would isolate these biases

The results, which we report in a forthcoming paper in the Journal of Experimental Psychology: General, were clear and robust. Those people who received desirable evidence — polls suggesting that their preferred candidate was going to win — took note and incorporated the information into their subsequent belief

. In contrast, those people who received undesirable evidence barely changed their belief about which candidate was most likely to win.

we observed a general bias toward the desirable evidence.

What about confirmation bias? To our surprise, those people who received confirming evidence — polls supporting their prior belief about which candidate was most likely to win — showed no bias in favor of this information.

They tended to incorporate this evidence into their subsequent belief to the same extent as those people who had their prior belief disconfirmed. In other words, we observed little to no bias toward the confirming evidence.

Our study suggests that political belief polarization may emerge because of peoples’ conflicting desires, not their conflicting beliefs per se

This is rather troubling, as it implies that even if we were to escape from our political echo chambers, it wouldn’t help much. Short of changing what people want to believe, we must find other ways to unify our perceptions of reality.

Republicans need to recognize finally that secure property rights, openness to global trade and a relatively low regulatory burden are much more important than fiscal policy for innovation, job creation and rising standards of

not only are sound safety nets popular, but they also increase the public’s tolerance for the dislocations of a dynamic free-market economy

Third, the idea that reducing taxpayer-financed government spending is the key to giving people more freedom and revving up the economy encourages conservative hostility to government as such

The Republican legislative agenda is stalled because party members have boxed themselves in with their own bad ideas about what freedom and rising prosperity require. A new pro-growth economic platform that sets aside small-government monomania and focuses instead on protecting citizens’ basic rights to commit “capitalist acts between consenting adults,” as the libertarian philosopher Robert Nozick put it, has both practical and political advantages

a generous and effective safety net can be embraced as a tool to promote and sustain a culture of freedom, innovation and risk taking. Politically, repairing and improving the slipshod infrastructure of the safety net would liberate Republicans from the bad faith of attacking the welfare state in one breath, halfheartedly promising not to cut entitlements in the next and then breaking that promise once in power.

A recent set of experiments shows us that there is a way to help reduce the effects of misinformation on people: the authors amusingly call it the “inoculation.”

which even then were heavily influenced by their pre-existing worldviews.

teaching about misconceptions leads to greater learning overall then just telling somebody the truth.

Neuroarchaeology is a new field which seeks to understand how ancient hominids and humans evolved cognitively.

Your brain engages in the same sort of prospection to provide its own instant answers, which come in the form of emotions. The main purpose of emotions is to guide future behavior and moral judgments, according to researchers in a new field called prospective psychology. Emotions enable you to empathize with others by predicting their reactions.

paid special attention to unexpected novelties because that was how they learned to avoid punishment and win rewards.

If traditional psychological theory had been correct, these people would have spent a lot of time ruminating. But they actually thought about the future three times more often than the past,

If Homo prospectus takes the really long view, does he become morbid? That was a longstanding assumption in psychologists’ “terror management theory,” which held that humans avoid thinking about the future because they fear death. The theory was explored in hundreds of experiments assigning people to think about their own deaths. One common response was to become more assertive about one’s cultural values, like becoming more patriotic.

The system may also play a role in symptoms of traumatic brain injur

Mice are a good model, she says, because their glymphatic systems are very similar to humans’. She and Iliff found that even months after being injured, the animals’ brains were still not clearing waste efficiently, leading to a buildup of toxic compounds, including amyloid beta. Nedergaard returns to the dishwasher analogy. “It’s like if you only use a third of the water when you turn on the machine,” she says. “You won’t get clean dishes.”

in mice, omega-3 fatty acidsimproved glymphatic functioning.

Nedergaard has shown that at least in mice, the system processes twice as much fluid during sleep as it does during wakefulness. She and her colleagues focused on amyloid beta; they found that the lymphatic system removed much more of the protein when the animals were asleep than when they were awake. She suggests that over time, sleep dysfunction may contribute to Alzheimer’s and perhaps other brain illnesses. “You only clean your brain when you’re sleeping,” she says. “This is probably an important reason that we sleep. You need time off from consciousness to do the housekeeping.”

Sleeping on your stomach is also not very effective; sleeping on your back is somewhat better, while lying on your side appears to produce the best results.

glymphatic flow is significantly decreased in the period just before a migraine. The intense pain in these headaches is caused largely by inflamed nerves in the tissue that surrounds the brain. Neuroscientists Rami Burstein and Aaron Schain, the lead authors, theorize that faulty clearance of molecular waste from the brain could trigger inflammation in these pain fibers.

other scientists have found that deep breathing significantly increases the glymphatic transport of cerebrospinal fluid into the brain.

When you see someone spooning sugar onto a bowl of cornflakes or Cheerios, you should not see the act as sweetening something that’s good for you, you should see it as someone spooning sugar onto sugar.

the biggest culprits in America’s bad health are sugar and refined grains, in that order. Sugar, a carbohydrate, now seems to be the chief villain. (In his recent book “The Case Against Sugar,” Taubes suggests it should be considered toxic in the same way cigarettes are.) But its nutritional cousin, the refined-grain carbohydrate, may be a close second.

Cereal was not always the morning staple that it is today. It only became so at about the same time that our health problems began to be documented, in the 1960s. A coincidence?

cereal was initially eaten on Sundays, when the women of our churchgoing nation didn’t have time to make the family breakfast. Once women entered the workforce, though, we began pouring our convenient breakfasts out of a box in significant numbers daily, a trend that peaked in 1995,

it may not even just be cereal that’s had such a huge impact on American health. “Maybe the problem,” Sukol said, “is the huge quantity of nutritionally bankrupt foods that are supposed to stand in for breakfast.”

By this she means anything composed primarily of refined wheat, which would be, um, 90 percent of the American breakfast repertoire: pancakes, waffles, bagels, toast, muffins, biscuits, scones, croissants, and so on.

eating this stuff on an empty stomach (i.e. in the morning), may be especially bad for your system, as there is little fiber, fat or protein in your system to slow the sugar absorption. Our breakfast staples might all best be considered as a single category of food: sugar bomb.

she nevertheless recommends that all her patients avoid what she calls “stripped” carbs, carbohydrates stripped of their fiber matrix, before noon.

What does she recommend for breakfast? Steel-cut oats, not cooked but rather soaked overnight with a dash of vinegar. I add whole-fat Greek yogurt and some nuts if I have them

Beans are great too. I had a delicious dish of lentils and a small amount of basmati rice

An egg and some cheese are also a nourishing and satisfying way to begin the day.

it throws a different light on the cereal aisle. That hulking behemoth in the middle of the grocery store, the racks of cereal, is stripped-carb and sugar ground zero, representing a kind of unrecognized terrorism wrought on parents by our own food makers

Here is what happened next: Hundreds of people began linking to it, tweeting and retweeting it, and adding their comments, which are too vulgar or racist to repeat. A few ultra-right-wing websites reprinted the story as fact. With each new cycle, the levels of hysteria rose, and people started demanding that I be fired, deported or killed. For a few days, the digital intimidation veered out into the real world. Some people called my house late one night and woke up and threatened my daughters, who are 7 and 12.

The people spreading this story were not interested in the facts; they were interested in feeding prejudice. The original story was cleverly written to provide conspiracy theorists with enough ammunition to ignore evidence. It claimed that I had taken down the post after a few hours when I realized it “receive[d] negative attention.”

an experiment performed by two psychologists in 1970. They divided students into two groups based on their answers to a questionnaire: high prejudice and low prejudice. Each group was told to discuss controversial issues such as school busing and integrated housing. Then the questions were asked again. “The surveys revealed a striking pattern,” Kolbert noted. “Simply by talking to one another, the bigoted students had become more bigoted and the tolerant more tolerant.” This “group polarization” is now taking place at hyper speed, around the world. It is how radicalization happens and extremism spreads.

By trial and error, Ms. Oakley had learned how to learn: “The higher I went, it started to gradually make more and more sense.”

“The way you learn intensively for a language is very similar to learning well in math and science,”

“In learning math and science through K-12, it’s long been held that practice and repetition will kill your creativity,” she says. “One mistake we make in the school system is we emphasize understanding. But if you don’t build those neural circuits with practice, it’ll all slip away. You can understand out the wazoo, but it’ll just disappear if you’re not practicing with it.”

In places like China and India, “practice and repetition and rote and memorization are really important parts of education.” She sees value in both methods: “There are real benefits for Western approaches—that it really does help with creativity. And there are also real benefits to Asian approaches—that it builds a solid foundation in the most difficult disciplines, math and science.

The best education would actually be a combination of both approaches.”

She defines a “mindshift” as “a change in your outlook that occurs through intensive learning”—such as her own mastery of math and engineering.

The book is filled with advice for people who are considering a career change or who seek to develop “an attitude of lifelong learning,” even in retirement.

Her progression from desultory student to respected scholar led her to a sideline in the study of learning itself. She’s published two books on the subject, “A Mind for Numbers: How to Excel at Math and Science (Even if You Flunked Algebra)” (2014) and the new “Mindshift: Break Through Obstacles to Learning and Discover Your Hidden Potential.

they developed a massive open online course, “Learning How to Learn,” which by some measures is the world’s most popular MOOC

The same technology that renders humans useless might also make it feasible to feed and support the unemployable masses through some scheme of universal basic income.

The real problem will then be to keep the masses occupied and content. People must engage in purposeful activities, or they go crazy. So what will the useless class do all day?

One answer might be computer games. Economically redundant people might spend increasing amounts of time within 3D virtual reality worlds, which would provide them with far more excitement and emotional engagement than the “real world” outside.

This, in fact, is a very old solution. For thousands of years, billions of people have found meaning in playing virtual reality games. In the past, we have called these virtual reality games “religions”.

Muslims and Christians go through life trying to gain points in their favorite virtual reality game. If you pray every day, you get points. If you forget to pray, you lose points. If by the end of your life you gain enough points, then after you die you go to the next level of the game (aka heaven).

As religions show us, the virtual reality need not be encased inside an isolated box. Rather, it can be superimposed on the physical reality. In the past this was done with the human imagination and with sacred books, and in the 21st century it can be done with smartphones.

Consumerism too is a virtual reality game. You gain points by acquiring new cars, buying expensive brands and taking vacations abroad, and if you have more points than everybody else, you tell yourself you won the game.

we saw two others kids on the street who were hunting the same Pokémon, and we almost got into a fight with them. It struck me how similar the situation was to the conflict between Jews and Muslims about the holy city of Jerusalem. When you look at the objective reality of Jerusalem, all you see are stones and buildings. There is no holiness anywhere. But when you look through the medium of smartbooks (such as the Bible and the Qur’an), you see holy places and angels everywhere.

In the end, the real action always takes place inside the human brain. Does it matter whether the neurons are stimulated by observing pixels on a computer screen, by looking outside the windows of a Caribbean resort, or by seeing heaven in our mind’s eyes?

Indeed, one particularly interesting section of Israeli society provides a unique laboratory for how to live a contented life in a post-work world. In Israel, a significant percentage of ultra-orthodox Jewish men never work. They spend their entire lives studying holy scriptures and performing religion rituals. They and their families don’t starve to death partly because the wives often work, and partly because the government provides them with generous subsidies. Though they usually live in poverty, government support means that they never lack for the basic necessities of life.

That’s universal basic income in action. Though they are poor and never work, in survey after survey these ultra-orthodox Jewish men report higher levels of life-satisfaction than any other section of Israeli society.

Hence virtual realities are likely to be key to providing meaning to the useless class of the post-work world. Maybe these virtual realities will be generated inside computers. Maybe they will be generated outside computers, in the shape of new religions and ideologies. Maybe it will be a combination of the two. The possibilities are endless

In any case, the end of work will not necessarily mean the end of meaning, because meaning is generated by imagining rather than by working.

People in 2050 will probably be able to play deeper games and to construct more complex virtual worlds than in any previous time in history.

But what about truth? What about reality? Do we really want to live in a world in which billions of people are immersed in fantasies, pursuing make-believe goals and obeying imaginary laws? Well, like it or not, that’s the world we have been living in for thousands of years already.

than if you do what people normally do in such situations, which is to go into the interview unprepared and to make choices by an overall intuitive judgment such as "I looked into his eyes and liked what I saw."
