A false story is much more likely to go viral than a real story, the authors find. A false story reaches 1,500 people six times quicker, on average, than a true story does.

“In short, I don’t think there’s any reason to doubt the study’s results,” said Rebekah Tromble, a professor of political science at Leiden University in the Netherlands, in an email.

It’s a question that can have life-or-death consequences.“[Fake news] has become a white-hot political and, really, cultural topic, but the trigger for us was personal events that hit Boston five years ago,” said Deb Roy, a media scientist at MIT and one of the authors of the new study.

Ultimately, they found about 126,000 tweets, which, together, had been retweeted more than 4.5 million times. Some linked to “fake” stories hosted on other websites. Some started rumors themselves, either in the text of a tweet or in an attached image. (The team used a special program that could search for words contained within static tweet images.) And some contained true information or linked to it elsewhere.

Tweet A and Tweet B both have the same size audience, but Tweet B has more “depth,” to use Vosoughi’s term. It chained together retweets, going viral in a way that Tweet A never did. “It could reach 1,000 retweets, but it has a very different shape,” he said.Here’s the thing: Fake news dominates according to both metrics. It consistently reaches a larger audience, and it tunnels much deeper into social networks than real news does. The authors found that accurate news wasn’t able to chain together more than 10 retweets. Fake news could put together a retweet chain 19 links long—and do it 10 times as fast as accurate news put together its measly 10 retweets.

What does this look like in real life? Take two examples from the last presidential election. In August 2015, a rumor circulated on social media that Donald Trump had let a sick child use his plane to get urgent medical care. Snopes confirmed almost all of the tale as true. But according to the team’s estimates, only about 1,300 people shared or retweeted the story.

Why does falsehood do so well? The MIT team settled on two hypotheses.First, fake news seems to be more “novel” than real news. Falsehoods are often notably different from the all the tweets that have appeared in a user’s timeline 60 days prior to their retweeting them, the team found.Second, fake news evokes much more emotion than the average tweet. The researchers created a database of the words that Twitter users used to reply to the 126,000 contested tweets, then analyzed it with a state-of-the-art sentiment-analysis tool. Fake tweets tended to elicit words associated with surprise and disgust, while accurate tweets summoned words associated with sadness and trust, they found.

It suggests—to me, at least, a Twitter user since 2007, and someone who got his start in journalism because of the social network—that social-media platforms do not encourage the kind of behavior that anchors a democratic government. On platforms where every user is at once a reader, a writer, and a publisher, falsehoods are too seductive not to succeed: The thrill of novelty is too alluring, the titillation of disgust too difficult to transcend. After a long and aggravating day, even the most staid user might find themselves lunging for the politically advantageous rumor. Amid an anxious election season, even the most public-minded user might subvert their higher interest to win an argument.

Emotions should never be bottled up. Call or go see someone you trust and recount to them what happened. Hearing an opinion other than your own broadens your awareness. Keep a journal and transfer your emotions from your inner self onto the paper. Many people find it helpful to engage in aggressive exercises, such as kickboxing or martial arts, to discharge their feelings.

Every happening of our lives, whether good or bad, serves a higher purpose. Wisdom means being able to see past the moment and discern the greater meaning of any given situation. You may not understand it in the beginning, but as time goes by, you'll begin to see the bigger picture falling into perfect order.

Whenever you are confronted with an emotion which is making you feel or think something bad, force it out of your mind and replace it with a different thought.

A constant reminder of our ardent nature, emotions surge through us at every second of the day.

Although Congress is now debating new Federal privacy legislation, I’m not optimistic that policymakers will be able to craft a law that will address these issues in a meaningful way — if they can create any law at all. There are too many stakeholders involved in the debate, each protecting their own economic self interest and competitive advantage in the marketplace

We need to engage more, make better informed decisions, use privacy settings and tools, and hold companies accountable when they misuse our data and violate our trust

As we debate privacy, we also shouldn’t forget that all of this new tech produces enormous benefits for our society - from curing diseases to easing traffic and reducing pollution

Instead she stayed and would then escalate what Christian Cooper said had been a polite request into a conflict. That's an odd reaction for someone scared for her life.

Yet she walked toward him quickly, filling the video screen as she reaches toward his phone camera, with dog leash and her own phone in hand. He asked her to back away: "please don't come close to me," he said twice in a calm, firm voice.

"I'm going to tell them there's an African American man threatening my life." Christian Cooper responded, telling her to "please tell them whatever you like." And so she does: "There's a man, African American, he has a bicycle helmet," she said into her phone, her tone breathless and urgent. "He is recording me and threatening me and my dog."

"I'm being threatened by a man in the Ramble!" she cried into the phone. "Please send the cops immediately!"

Amy Cooper's decision to summon the police against a man who did nothing more than ask her to follow the rules reads as nothing short of a potential threat to his life.

She, a white woman (and she didn't have to even say that explicitly; she knew it would be grasped by whoever had answered the phone) would be seen as vulnerable and in need of protection, and her story would be believed on its face; he, a black man, would be seen as menacing and potentially dangerous, and his version of events would be doubted or disregarded.

Ahmaud Arbery, a black man in Georgia, was just out for a run last February when, authorities say, Gregory and Travis McMichael, two white men (one of them a former police officer, as it happened), grabbed their guns, chased him down, and shot him to death. They faced no criminal penalties and were simply let off the hook until a video emerged of their attack, and public outcry forced law enforcement to act. (The two have not been asked by a judge for a plea, and attorneys for the men have told reporters they committed no crimes, according to CNN reporting.) Without the video, the wheels of justice would likely never have even begun to turn.

We see again and again that African Americans who are victims of serious crimes need unimpeachable video evidence to be believed. Overwhelmingly, though, crimes are not caught on video. And even when they are, we have seen repeatedly that law enforcement often doesn't act until they are compelled by a huge public outcry. Without reliably fair law enforcement, there are simply few avenues for justice.

To be sure, it's easy to find legitimate criticism of Twitter "justice." But this only raises the more important question of why our formal mechanisms for justice are so often so inept at providing justice across racial lines -- why the very people and institutions we should be able to trust are instead often threats to the lives and safety of African Americans. When calling the cops is understood as a threat to a black person -- and sometimes even a threat to that person's life-- that's not just an indictment of the cop-caller, that's an indictment of the police, of prosecutors, of juries and of too many in a white American public willing to accept this reality.

Amy Cooper has issued an apology (she told CNN she wanted to "publicly apologize to everyone"), but in explaining her egregious actions, said "I'm not a racist. I did not mean to harm that man in any way." How do you not mean to harm someone when you call the police and falsely claim he is threatening you? "I think I was just scared," Amy Cooper said. "When you're alone in the Ramble, you don't know what's happening. It's not excusable, it's not defensible."

Her woe-is-me complaints are a bit hard to swallow given her own actions, which could have damaged or destroyed the life of an innocent man.

let's keep our eyes on the prize: a justice system that works, rather than one which so often accepts the word of white people at the expense of black lives and freedom.

Step two: "Log moments of joy"This means simply saying to yourself -- as you sip a great espresso, laugh at your friend's joke or buy that shirt you've wanted -- "I am having a moment of joy!" When negative things happen to us throughout the day we tend to hold on to them, while the good things are more fleeting and ephemeral. So, by consciously acknowledging the good things, says Meng, we increase our chances that when we reflect on our day, we conclude it was happy one.

I asked psychologist Tom Stafford, who writes the Neurohacks column for BBC Future about the gap. "Squaring what works for you and what the science says is difficult because happiness is a complex object," he told me. "There will be local variations due to individual personality, so we've immediately got a reason for expecting a gap between the science -- which tends to work with group averages -- and any one person's experience."The interesting general question, to me, is when do we trust our experience and when do we listen to science," Stafford added. "Obviously some things we don't need science for ('Does dropping a rock on my foot hurt?'), and some things we do ('Is smoking bad for my health?'). Happiness, I'd argue, is in between these two cases."

To many, Meng's three steps may seem obvious or simplistic. Yet he compared his advice to showing us how to do a single push up or arm curl at the gym. You know it does you good, but you have to do the exercise every day to get results. I may be more experientially convinced than scientifically sated, but it's enough to keep me going to Google's happiness gym and doing those push-ups.

The day-to-day work of a pilot is unstable, and often unpredictable. They’re away from home, and from their families, for long stretches of time. The job isn’t a typical 9-to-5— instead, pilots fly overnight from timezone to timezone, at strange hours.

To reduce fatigue, which is linked to stress, rules and regulations from the Federal Aviation Administration (FAA) limit the number of hours a pilot can fly and how much rest they need. During a 24-hour period, a pilot flying alone can’t log more than eight hours, for example, and they have a ten-hour minimum rest period before taking off.

But if stress creeps past that midpoint, performance starts to drop off. Too-high levels of stress mean exhaustion, panic, and blunted brain power. That’s when mistakes happen.

CRM training is designed to help pilots and crew members develop efficiency communication and decision-making skills. “It was also saying, this is what fatigue looks like, and this is how to recognize it in your co-pilot,” Bowen says. From that point on, she says, the airlines worked to develop a culture where pilots would hold other pilots accountable when they weren’t fit to fly. “It was about not protecting their buddy, but protecting overall safety,” Bowen says.

Pilot mental health is another big issue to tackle, says Quay Snyder, a former Air Force flight surgeon and a member of the Aerospace Medical Association Working Group on Pilot Mental Health. Pilots are often reluctant to acknowledge the effect that emotional stressors might have on their ability to fly, he says.

“They’re slow to recognize mental health issues,” he says, “and they might think there’s a stigma against asking for help.”

“Pilots trust pilots,” he says. “Hearing from a peer could help a pilot recognize that they may not be fit to fly. Hearing it from a physician doesn’t carry much weight, but hearing it from a peer does.”

The new process may also help in other procedures where doctors need to analyze tissue while they are still operating, such as head and neck, breast, skin and gynecologic surgery, the report said. It also noted that there is a shortage of neuropathologists, and suggested that the new technology might help fill the gap in medical centers that lack the specialty.

Algorithms are also being developed to help detect lung cancers on CT scans, diagnose eye disease in people with diabetes and find cancer on microscope slides.

The diagnoses were later judged right or wrong based on whether they agreed with the findings of lengthier and more extensive tests performed after the surgery.The result was a draw: humans, 93.9 percent correct; A.I., 94.6 percent.

At some centers, he said, brain surgeons do not even order frozen sections because they do not trust them and prefer to wait for tissue processing after the surgery, which may take weeks to complete.

Some types of brain tumor are so rare that there is not enough data on them to train an A.I. system, so the system in the study was designed to essentially toss out samples it could not identify.

“It won’t change brain surgery,” he said, “but it’s going to add a significant new tool, more significant than they’ve stated.”

frican-Americans are at greater risk of being killed by police, even though they are less likely to pose an objective threat to law enforcement, according to research by Northeastern University Professor Matt Miller.

Among those who were "unarmed and appeared to show no objective threat to police, nearly two-thirds of the victims were Hispanic or Black," the researchers found.

"there is profound racial disparity in the misdemeanor arrest rate for most -- but not all -- offense types,"

The 2017 study found that black residents were more likely to file complaints than white residents -- but "NCPD sustained complaints filed by Black residents only 31 percent of the time compared to sustaining complaints filed by White residents 50 percent of the time," the study says. "NCPD defines 'sustained' as 'the allegation is supported by sufficient evidence to justify a reasonable conclusion that the allegation is factual."

Latino youth are 65% more likely to be detained or committed than their white peers, according to a 2017 report from The Sentencing Project.

African Americans and whites use drugs at similar rates, but the imprisonment rate of African Americans for drug charges is almost 6 times that of whites, the NAACP said.

But they found that "blacks were 2.7 times more likely to be pulled over in an investigatory stop," NPR station KCUR reported. "Blacks were also subject to searches five times more often than white drivers."

But black drivers who had an infraction like a burnt out light were more often "questioned about what they were doing in a particular neighborhood, where they were heading, and whether they were carrying drugs," the report said. "Many were subject to vehicle searches."

"When you have the national security adviser saying he doesn't see systemic racism, well you know what? White folks also didn't see systemic racism even in the 1960s," Wise said.

"If white America didn't get it even when it was obvious in retrospect to everyone, what in the world would make the national security adviser believe that he or anyone else knows what they're talking about now? I think it probably stands to reason that black and brown folks know their reality better than we do."

"Especially after a tragedy like we saw in Minneapolis, we need to do two things -- take a hard look at our own actions and conduct, correct them where necessary, and to regain that trust by continuing to hold ourselves to the highest possible standard in a transparent way."

"In these kinds of public health emergencies, we need to be able to trust our leaders, be it public health, scientific or political leaders," Omer said. This will become particularly important in the coronavirus outbreak if there comes a time when the government needs to recommend major lifestyle adjustments to curtail the spread of the disease.

I was relieved -- we wouldn't have to make what felt like an impossible decision -- but then I kept reading. My father had noted that he did not want to be supported by a ventilator or hooked up to a feeding tube for any length of time. He had been connected to both for nearly two weeks.

There was grief on her face, but also curiosity. What had finally gotten to her younger son, the one who so rarely showed emotion during his father's hospitalization?

I called the hospital and approved the DNR. They told me his status was still dire. I called my dad's closest friends and started preparing them for the worst.

My father's lungs showed no signs of progress. The double pneumonia they diagnosed days before was worsening. His kidneys were failing. Dialysis was required but would put a strain on his blood pressure, which was already dangerously low. There was a special form of dialysis designed for delicate situations like this -- continuous veno-venous hemofiltration -- but it wasn't available at Lawrence

The morning after I searched for my father's health directive and drafted his obituary, I woke up and tried to turn on my laptop. It wouldn't start. When it eventually booted up, it asked if I wanted to restore an unsaved document. No, I thought, let's see what happens today.

It was the same doctor as yesterday, the one who asked about the DNR. "Look, your dad is on a ventilator. That's a form of life support. He's experiencing kidney failure and requires dialysis. His situation is still very acute. He was in good health before the Covid, but his kidney, heart, and lungs are 69 years old. It's tough for them to recover. But the numbers from today are undeniably better than yesterday. There's been an improvement at almost every level. Your dad is a tough guy."

One of my close friends, a nurse practitioner, would help me understand all the terminology and its implications. He was treating Covid patients at an ICU upstate. At the end of our calls I'd ask him how he was doing. "We ran out of gowns," he told me one day. "My ICU is out of ventilators -- we're diverting people to Albany," he said another time.

"There's a difference between good intentions and good outcomes," I explained to her. She would wave me away and pick up. Inevitably the call would bring her tears. I stewed on the porch. My brother, uncle and I would spend hours trying to ease her mind and pacify her anxiety. Any inquiry or outreach was like sticking a finger in the open wound of her anguish.

I called my friend, the nurse practitioner, and gave him the latest update. He seemed upset. "You OK, dude?" "A nurse from my hospital died," he explained.

The nurses and doctors who took care of my father -- first for four days at NewYork-Presbyterian Lawrence Hospital, then for nearly a month at NewYork-Presbyterian/Columbia -- were always empathetic, straightforward and willing to trust me with complicated details.

About a week after writing -- then refusing to recover -- my father's obituary, his condition was continuing to improve.

"He's only improving," I told her, "because of the life-saving care you guys have given him. The whole city is in awe of you. They should have a parade for you down the Canyon of Heroes."

Covid-19 was new and largely unstudied. Maybe one of these seemingly odd treatments would work.

"Yesterday was a stumble, but we're getting back on course," I emailed the group. "We always knew this recovery wasn't going to be a straight line. It's important to remain resilient and optimistic even when there are temporary setbacks."

"Oh Lou, I've been waiting for your call. I have such good news. They are planning to extubate him tomorrow. They are going to take your father off the ventilator!" She was practically screaming with excitement. I was speechless.

I had been withholding certain information from my family and friends during this whole ordeal. My dad had developed a blood clot two weeks into his hospitalization. Clots are extremely dangerous, of course, but it was small and in a relatively manageable location.

I called my brother and told him about the plan to get my father off the ventilator. Since there were a number of contingencies, we debated telling my mother. She was living and dying with every update.

My father's breathing was labored on the morning they were planning to extubate. They delayed the procedure a day. That next morning, April 16, a doctor called. I was in the shower and rushed out to answer my cell. He said they were doing the extubation within the hour. What do we want to do if the extubation fails?

"It went as well as we could have hoped for," the doctor said. "His vitals are stable and he's breathing well. He's resting now." She explained that my father was disoriented and it probably wasn't a great idea to speak with him that day. Whatever, I thought, I'll speak with him when he gets home. He had been on a ventilator for 28 days.

I called the doctor later in the day. She told me my dad seemed distressed. He was trying to speak, but his vocal cords were too swollen. "It's so frustrating," she told me. "I don't know what he wants to tell me."

"Each facility has their own Covid rules," she explained. "I'll send you over a list." On the list was the nursing home where my grandfather had died several years before. My father had visited him every day.

I called the step-down unit where he had been the past three days. They transferred me to his nurse. "He's doing better, love. We took him off the pressor and his blood pressure is in a good range. His heart rate is good. He's breathing fine. The doctors decided he didn't need to go back to the ICU. He's ok."

"I've repeatedly said that recovery isn't a straight line. ... Yesterday we managed the roller coaster ride as a family. My brother, uncle and I were with my mother the entire day. We never lost hope or confidence in my dad's medical care and ultimate recovery. If there's a light at the end of the tunnel, it's a blinking one. Right now, it shines again."

I drove back to my mom's house. I scanned the block for my brother's car. He had not arrived. I parked. I have to wait for him and then tell my mother, brother and uncle all at once, right? Should I call my wife first? Should I call my dad's best friend?

I called my wife. I called my dad's best friend. I called the guys he grew up with. I called his former colleagues. I began every conversation the same way, "This is that call." I listened to each of them yell and cry and ask if I was serious. Then I said I had to make another call.

I wrote about my father's career. How he got his law degree at night school and became a prosecutor at the city, state, and federal level. How he convicted mobsters, drug dealers, and those who abused power.

I wrote about my dad's volunteer work -- at the Special Olympics, at an organization he founded that helps police families with special needs, and at just about any Italian-American group that needed a lawyer. He was so proud of his Italian-American heritage. He loathed the mafioso caricatures and stereotypes found on TV -- he wrote countless op-eds attacking those -- but he revered the old-school virtues he associated with his Italian-American upbringing: loyalty, humility, hard work, dedication to family.

He was a Covid patient for 31 days. It was a painful experience, but ultimately unimportant. It doesn't matter how a man dies. It matters how he lives.

If the breaths don't make a dent, try explaining what's happening to yourself. "I'm annoyed right now because ..." is a good sentence to finish. Articulating the issue changes your response from emotion to logic.

Make use of this step when another person is part of the reason you are upset. Try hard to see the situation from their reality and invent a subjective theory for why they did what they did.

Think beyond the annoyance, or annoying person, and focus on your own behavior. By thinking of how you can be a model for grace under pressure, you help yourself to become one.

If you've hit No. 10, it's time to talk about the frustration with someone you trust who is not involved in the situation. Start by telling them what you did in the previous steps and why they didn't fully work.

How important is the matter upsetting you? How does it stack up against the things in life that you know matter? What is important (loved ones are a good example) can be the antidote to what troubles you now -- as long as you can bring them to mind in this moment.

Whatever the annoyance, make a joke about it, even if it's a bad one. If you can find some grain of humor in the situation, smiling, laughing and even being silly can all defuse anger and annoyance. It's not psychologically possible to experience two emotions at once.

If you've made it this far up the steps and you are still really peeved, here's a good (if seemingly obvious) question to ask yourself: "Is there something I can do to make it better?" Even if the answer is a small step that may not seem that effective, just taking action gets you out into the frame of acting, not reacting.

In the future, it is possible that you will see this particular anger-causing situation differently. Look at past problems and see how they've been a catalyst for change or even a blessing in disguise. You may even look back at a difficult situation with fondness, humor or gratefulness (for having overcome it). It's worth keeping in mind that what seems bad now won't always be so.

Whatever it is that is getting your goat, it is temporary and manageable. You won't always feel this way. It's just a question of how long.

Beyond improvements to your general mood and happiness, taming your anger can have important benefits to your health. Constant stress and aggravation is linked to a range of issues including overeating, insomnia and depression, and angry outbursts increase the risk of heart attacks and strokes.

"People who are more socially connected to family, to friends, to community, are happier, they're physically healthier, and they live longer than people who are less well connected," said Harvard psychiatrist Robert Waldinger in his popular TEDx talk. "And the experience of loneliness turns out to be toxic."

The lessons aren't about wealth or fame or working harder and harder," Waldinger said. "The clearest message that we get from this 75-year study is this: Good relationships keep us happier and healthier. Period."

"In fact, the more positive the person, the greater the protection from heart attacks, stroke and any cause of death," said Mt. Sinai's Rozanski, who was the lead author on the study.

A sense of purpose and meaning in your life is a big part of living a longer, happier life, according to psychology professor Lyle Ungar, who has developed what he calls the Well-Being Map. It rates every US county on such psychological factors as openness, trust, agreeableness and neuroticism.

"If your sole duty is to achieve the best for yourself, life becomes just too stressful, too lonely -- you are set up to fail. Instead, you need to feel you exist for something larger, and that very thought takes off some of the pressure."

SpiritualityStudies by the Pew Research Center show that actively religious people are more likely than less- or non-religious people to describe themselves as "very happy." They also share some traits that could improve their chance at a longer, happy life: They are less likely to smoke and drink, and more likely to join clubs and volunteer at charities.

"I'm surprised how good religion is for people," Ungar said. "Religious people are more agreeable, they're happier, they live longer."It doesn't have to be a traditional religion. Layard points out that spiritual practices ranging from meditation to positive psychology to cognitive therapy can also feed an inner life.

America’s word is worth less today than at any time since 1945. Trust is not an easily recoverable commodity. Solemn accords entered into by the United States, like the Iran nuclear deal, are ripped up — and replaced by empty threats. Friends like the Kurds who have shed blood to inflict great harm on the Islamic State are betrayed. Day after day a president for whom facts don’t matter dismantles the idea of truth.

A recent report from Patrick Wintour in The Guardian quoted the Saudi ambassador to Britain calling Trump a “tweet monster” and saying the abrupt American troop withdrawal from northern Syria “does not give one incredible confidence.”

Sure, but this Middle East demeans the sacrifice of the thousands of Americans who died for something better, and makes a nonsense of the nearly trillion American dollars spent to that end. Trump is not cutting losses; he’s perpetuating them. Iran could not have asked for American chaos more conducive to its interests. Nor could Putin, al-Assad and Erdogan.

Trump folded to Turkey’s Kurd Derangement Syndrome. Even the plankton known as the Republican Party were so appalled that some lawmakers developed sufficient backbone to protest.

“Foreign policy is what I’ll be remembered for,” Trump has said. Damn right.

Administering a nationally representative phone survey with 1,008 respondents, they found that people who got most of their information from mainstream print and broadcast outlets tended to have an accurate assessment of the severity of the pandemic and their risks of infection.

But those who relied on conservative sources, such as Fox News and Rush Limbaugh, were more likely to believe in conspiracy theories or unfounded rumors, such as the belief that taking vitamin C could prevent infection, that the Chinese government had created the virus, and that the U.S. Centers for Disease Control and Prevention was exaggerating the pandemic’s threat “to damage the Trump presidency.”

“The effect that we measure could be driven by the long-term message of Fox News, which is that the mainstream media often report ‘fake news’ and have a political agenda,” Simonov said. “This could result in lowering trust in institutions and experts, including health experts in the case of the pandemic.”

Our results indicate that a one standard deviation increase in relative viewership of Hannity relative to Tucker Carlson Tonight is associated with approximately 32 percent more COVID-19 cases on March 14 and approximately 23 percent more COVID-19 deaths on March 28,

“If the results hold, the research demonstrates the influence that broadcast media can have on behavior,”

Haidt argues that people are fundamentally intuitive, not rational.

Politics isn’t just about ­manipulating people who disagree with you. It’s about learning from them.

They exalt families, armies and communities. They assume that people should be treated differently according to social role or status — elders should be honored, subordinates should be protected.

Is it wrong to have sex with a dead chicken? How about with your sister? Is it O.K. to defecate in a urinal? If your dog dies, why not eat it? Under interrogation, most subjects in psychology experiments agree these things are wrong. But none can explain why.

They do reason. But their arguments aim to support their conclusions, not yours.

Haidt’s account of reason is a bit too simple — his whole book, after all, is a deployment of reason to advance learning — and his advice sounds cynical.

Haidt replies: We were never designed to listen to reason. When you ask people moral questions, time their responses and scan their brains, their answers and brain activation patterns indicate that they reach conclusions quickly and produce reasons later only to justify what they’ve decided.

The Tea Party hates redistribution because it interferes with letting people reap what they earn. Faith, patriotism, valor, chastity, law and order — these Republican themes touch all six moral foundations, whereas Democrats, in Haidt’s analysis, focus almost entirely on care and fighting oppression.

When it comes to morality, conservatives are more broad-minded than liberals. They serve a more varied diet.

He figures that if voters like Republican messages, there’s something in Republican messages worth liking. He chides psychologists who try to “explain away” conservatism, treating it as a pathology.

parochial altruism, the inclination to care more about members of your group — particularly those who have made sacrifices for it —than about outsiders.

The hardest part, Haidt finds, is getting liberals to open their minds.

“fewer people believe that righteous ends justify violent means.”

Can we tolerate cultures of female subjugation? And how far should we trust our instincts? Should people who find homosexuality repugnant overcome that reaction?

But Haidt is right that we must learn what we have been, even if our nature is to transcend it.
