The Psychology of Risk Perception Explains Why People Don't Fret the Pacific Northwest'... - 0 views

  • what psychology teaches us. Turns out most of us just aren’t that good at calculating risk, especially when it comes to huge natural events like earthquakes. That also means we’re not very good at mitigating those kinds of risks. Why? And is it possible to get around our short-sightedness, so that this time, we’re actually prepared? Risk perception is a vast, complex field of research. Here are just some of the core findings.
  • Studies show that when people calculate risk, especially when the stakes are high, we rely much more on feeling than fact. And we have trouble connecting emotionally to something scary if the odds of it happening today or tomorrow aren’t particularly high. So, if an earthquake, flood, tornado or hurricane isn’t immediately imminent, people are unlikely to act. “Perceiving risk is all about how scary or not do the facts feel,”
  • This feeling also relates to how we perceive natural, as opposed to human-made, threats. We tend to be more tolerant of nature than of other people who would knowingly impose risks upon us—terrorists being the clearest example. “We think that nature is out of our control—it’s not malicious, it’s not profiting from us, we just have to bear with it,”

  • And in many cases, though not all, people living in areas threatened by severe natural hazards do so by choice. If a risk has not been imposed on us, we take it much less seriously. Though Schulz’s piece certainly made a splash online, it is hard to imagine a mass exodus of Portlanders and Seattleites in response. Hey, they like it there.
  • They don’t have much to compare the future earthquake to. After all, there hasn’t been an earthquake or tsunami like it there since roughly 1700. Schulz poeticizes this problem, calling out humans for their “ignorance of or an indifference to those planetary gears which turn more slowly than our own.” Once again, this confounds our emotional connection to the risk.
  • But our “temporal parochialism,” as Schulz calls it, also undoes our grasp on probability. “We think probability happens with some sort of regularity or pattern,” says Ropeik. “If an earthquake is projected to hit within 50 years, when there hasn’t been one for centuries, we don’t think it’s going to happen.” Illogical thinking works in reverse, too: “If a minor earthquake just happened in Seattle, we think we’re safe.”
  • The belief that an unlikely event won’t happen again for a while is called a gambler’s fallacy. Probability doesn’t work like that. The odds are the same with every roll of the dice.
  • For individuals and government alike, addressing every point of concern requires a cost-benefit analysis. When kids barely have pencils and paper in schools that already exist, how much is appropriate to invest in earthquake preparedness? Even when that earthquake will kill thousands, displace millions, and cripple a region’s economy for decades to come—as Cascadia is projected to—the answer is complicated. “You immediately run into competing issues,” says Slovic. “When you’re putting resources into earthquake protection that has to be taken away from current social needs—that is a very difficult sell.”​
  • There are things people can do to combat our innate irrationality. The first is obvious: education. California has a seismic safety commission whose job is to publicize the risks of earthquakes and advocate for preparedness at household and state policy levels.
  • Another idea is similar to food safety ratings in the windows of some cities’ restaurants. Schulz reports that some 75 percent of Oregon’s structures aren’t designed to hold up to a really big Cascadia quake. “These buildings could have their risk and safety score publicly posted,” says Slovic. “That would motivate people to retrofit or mitigate those risks, particularly if they are schools.”
  • science points to a hard truth. Humans are simply inclined to be more concerned about what’s immediately in front of us: Snakes, fast-moving cars, unfamiliar chemical compounds in our breakfast cereal and the like will always elicit a quicker response than an abstract, far-off hazard.

The Age of Protest - The New York Times - 0 views

  • If you go to The Guardian’s website these days you can find a section that is just labeled “Protest.” So now, with your morning coffee, you can get your news, weather, sports — and protests.
  • In my view, this age of protest is driven, in part, by the fact that the three largest forces on the planet — globalization, Moore’s law and Mother Nature — are all in acceleration, creating an engine of disruption that is stressing strong countries and middle classes and blowing up weak ones, while superempowering individuals and transforming the nature of work, leadership and government all at once.
  • When you get that much agitation in a world where everyone with a smartphone is now a reporter, news photographer and documentary filmmaker, it’s a wonder that every newspaper doesn’t have a “Protest” section.
  • ...8 more annotations...
  • “People everywhere seem to be morally aroused,” said Seidman. “The philosopher David Hume argued that ‘the moral imagination diminishes with distance.’ It would follow that the opposite is also true: As distance decreases, the moral imagination increases. Now that we have no distance — it’s like we’re all in a crowded theater, making everything personal — we are experiencing the aspirations, hopes, frustrations, plights of others in direct and visceral ways.”
  • “A dentist from Minnesota shoots a cherished lion in Zimbabwe named Cecil, and days later everyone in the world knows about it, triggering a tsunami of moral outrage on Twitter and Facebook. As a result, some people try to shut down his dental practice by posting negative reviews on Yelp and spray paint ‘Lion Killer’ on his Florida vacation home. Almost 400,000 people then sign a petition in one day on Change.org demanding that Delta Air Lines change their policy of transporting trophy kills. Delta does so and other airlines follow. And then hunters who contribute to Zimbabwe’s tourism industry protest the protest, claiming that they were being discriminated against.”
  • That we are becoming more morally aroused “is generally a good thing,” argued Seidman. Institutionalized racism in police departments, or in college fraternities, is real and had been tolerated for way too long. That it’s being called out is a sign of a society’s health “and re-engagement.”
  • But when moral arousal manifests as moral outrage, he added, “it can either inspire or repress a serious conversation or the truth.”
  • “If moral outrage, as justified as it may be, is followed immediately by demands for firings or resignations,” argued Seidman, “it can result in a vicious cycle of moral outrage being met with equal outrage, as opposed to a virtuous cycle of dialogue and the hard work of forging real understanding and enduring agreements.”
  • Furthermore, “when moral outrage skips over moral conversation, then the outcome is likely going to be acquiescence, not inspired solutions,” Seidman added. It can also feed the current epidemic of inauthentic apologies, “since apologies extracted under pressure are like telling a child, `Just say you’re sorry,’ to move past the issue without ever making amends.”
  • it’s as if “we’re living in a never-ending storm,” he said. Alas, though, resolving moral disputes “requires perspective, fuller context and the ability to make meaningful distinctions.”
  • requires leaders with the courage and empathy “to inspire people to pause to reflect, so that instead of reacting by yelling in 140 characters they can channel all this moral outrage into deep and honest conversations.”

Facebook's Bias Is Built-In, and Bears Watching - The New York Times - 2 views

  • Facebook is the world’s most influential source of news.That’s true according to every available measure of size — the billion-plus people who devour its News Feed every day, the cargo ships of profit it keeps raking in, and the tsunami of online traffic it sends to other news sites.
  • But Facebook has also acquired a more subtle power to shape the wider news business. Across the industry, reporters, editors and media executives now look to Facebook the same way nesting baby chicks look to their engorged mother — as the source of all knowledge and nourishment, the model for how to behave in this scary new-media world. Case in point: The New York Times, among others, recently began an initiative to broadcast live video. Why do you suppose that might be? Yup, the F word. The deal includes payments from Facebook to news outlets, including The Times.
  • Yet few Americans think of Facebook as a powerful media organization, one that can alter events in the real world. When blowhards rant about the mainstream media, they do not usually mean Facebook, the mainstreamiest of all social networks. That’s because Facebook operates under a veneer of empiricism. Many people believe that what you see on Facebook represents some kind of data-mined objective truth unmolested by the subjective attitudes of fair-and-balanced human beings.
  • ...11 more annotations...
  • None of that is true. This week, Facebook rushed to deny a report in Gizmodo that said the team in charge of its “trending” news list routinely suppressed conservative points of view. Last month, Gizmodo also reported that Facebook employees asked Mark Zuckerberg, the social network’s chief executive, if the company had a responsibility to “help prevent President Trump in 2017.” Facebook denied it would ever try to manipulate elections.
  • Even if you believe that Facebook isn’t monkeying with the trending list or actively trying to swing the vote, the reports serve as timely reminders of the ever-increasing potential dangers of Facebook’s hold on the news.
  • The question isn’t whether Facebook has outsize power to shape the world — of course it does, and of course you should worry about that power. If it wanted to, Facebook could try to sway elections, favor certain policies, or just make you feel a certain way about the world, as it once proved it could do in an experiment devised to measure how emotions spread online.
  • There is no evidence Facebook is doing anything so alarming now. The danger is nevertheless real. The biggest worry is that Facebook doesn’t seem to recognize its own power, and doesn’t think of itself as a news organization with a well-developed sense of institutional ethics and responsibility, or even a potential for bias. Neither does its audience, which might believe that Facebook is immune to bias because it is run by computers.
  • That myth should die. It’s true that beyond the Trending box, most of the stories Facebook presents to you are selected by its algorithms, but those algorithms are as infused with bias as any other human editorial decision.
  • “With Facebook, humans are never not involved. Humans are in every step of the process — in terms of what we’re clicking on, who’s shifting the algorithms behind the scenes, what kind of user testing is being done, and the initial training data provided by humans.”Everything you see on Facebook is therefore the product of these people’s expertise and considered judgment, as well as their conscious and unconscious biases apart from possible malfeasance or potential corruption. It’s often hard to know which, because Facebook’s editorial sensibilities are secret. So are its personalities: Most of the engineers, designers and others who decide what people see on Facebook will remain forever unknown to its audience.
  • Facebook also has an unmistakable corporate ethos and point of view. The company is staffed mostly by wealthy coastal Americans who tend to support Democrats, and it is wholly controlled by a young billionaire who has expressed policy preferences that many people find objectionable.
  • You could argue that none of this is unusual. Many large media outlets are powerful, somewhat opaque, operated for profit, and controlled by wealthy people who aren’t shy about their policy agendas — Bloomberg News, The Washington Post, Fox News and The New York Times, to name a few.But there are some reasons to be even more wary of Facebook’s bias. One is institutional. Many mainstream outlets have a rigorous set of rules and norms about what’s acceptable and what’s not in the news business.
  • Those algorithms could have profound implications for society. For instance, one persistent worry about algorithmic-selected news is that it might reinforce people’s previously held points of view. If News Feed shows news that we’re each likely to Like, it could trap us into echo chambers and contribute to rising political polarization. In a study last year, Facebook’s scientists asserted the echo chamber effect was muted.
  • are Facebook’s engineering decisions subject to ethical review? Nobody knows.
  • The other reason to be wary of Facebook’s bias has to do with sheer size. Ms. Caplan notes that when studying bias in traditional media, scholars try to make comparisons across different news outlets. To determine if The Times is ignoring a certain story unfairly, look at competitors like The Washington Post and The Wall Street Journal. If those outlets are covering a story and The Times isn’t, there could be something amiss about the Times’s news judgment.Such comparative studies are nearly impossible for Facebook. Facebook is personalized, in that what you see on your News Feed is different from what I see on mine, so the only entity in a position to look for systemic bias across all of Facebook is Facebook itself. Even if you could determine the spread of stories across all of Facebook’s readers, what would you compare it to?

  • He said more than 200 people were receiving treatment at the Bhayangkara police hospital and several others in Mamuju alone. Another 630 were injured in Majene.
  • The quake set off landslides in three locations and blocked a main road connecting Mamuju to Majene. Power and phone lines were down in many areas.
  • A governor office building was almost flattened by the quake and a shopping mall was reduced to a crumpled hulk.
  • Two ships headed to the devastated areas from the nearby cities of Makassar and Balikpapan with rescuers and equipment, including excavators.
  • The pope was praying for “the repose of the deceased, the healing of the injured and the consolation of all who grieve.” Francis also offered encouragement to those continuing search and rescue effects, and he invoked “the divine blessings of strength and hope.”
  • Indonesia, home to more than 260 million people, is frequently hit by earthquakes, volcanic eruptions and tsunamis because of its location on the “Ring of Fire,” an arc of volcanoes and fault lines in the Pacific Basin.

How our brains numb us to covid-19's risks - and what we can do about it - The Washingt... - 1 views

  • Social scientists have long known that we perceive risks that are acute, such as an impending tsunami, differently than chronic, ever-present threats like car accidents
  • Part of what’s happening is that covid-19 — which we initially saw as a terrifying acute threat — is morphing into more of a chronic one in our minds. That shift likely dulls our perception of the danger,
  • Now, when they think about covid-19, “most people have a reduced emotional reaction. They see it as less salient.”
  • ...15 more annotations...
  • This habituation stems from a principle well-known in psychological therapy: The more we’re exposed to a given threat, the less intimidating it seems.
  • As the pandemic drags on, people are unknowingly performing a kind of exposure therapy on themselves, said University of Oregon psychologist Paul Slovic, author of “The Perception of Risk” — and the results can be deadly.
  • “You have an experience and the experience is benign. It feels okay and comfortable. It’s familiar. Then you do it again,” Slovic said. “If you don’t see anything immediately bad happening, your concerns get deconditioned.”
  • The end result of all this desensitizing is a kind of overriding heedlessness decoupled from evidence — the anti-mask movements, the beach gatherings, the overflowing dance parties
  • One of the best ways to reinforce a certain behavior is to make sure that behavior is rewarded and that deviations from it are punished (or ignored).
  • But when it comes to lifesaving behaviors such as mask-wearing or staying home from parties, this reward-punishment calculus gets turned on its head.
  • With parties, when you do the right thing and stay home, “you feel an immediate cost: You’re not able to be with your friends,
  • while there is an upside to this decision — helping to stop the spread of the virus — it feels distant. “The benefit is invisible, but the costs are very tangible.”
  • By contrast, Slovic said, when you flout guidelines about wearing masks or avoiding gatherings, you get an immediate reward: You rejoice at not having to breathe through fabric, or you enjoy celebrating a close friend’s birthday in person.
  • Because risk perception fails as we learn to live with covid-19, Griffin and other researchers are calling for the renewal of tough government mandates to curb virus spread. They see measures such as strict social distancing, enforced masking outside the home and stay-at-home orders as perhaps the only things that can protect us from our own faulty judgment.
  • But these kinds of measures aren’t enough on their own, Griffin said. It’s also important for authorities to supply in-your-face reminders of those mandates, especially visual cues, so people won’t draw their own erroneous conclusions about what’s safe.
  • “A few parks have drawn circles [on their lawns]: ‘Don’t go out of the circle,’ ” Griffin said. “We need to take those kinds of metaphors and put them throughout the entire day.”
  • “The first step is awareness that sometimes you can’t trust your feelings.”
  • For people considering how to assess covid-19 risks, Slovic advised pivoting from emotionally driven gut reactions to what psychologist Daniel Kahneman — winner of the 2002 Nobel Prize in economics for his integration of psychological research into economic science — calls “slow thinking.” That means making decisions based on careful analysis of the evidence. “You need to either do the slow thinking yourself,” Slovic said, “or trust experts who do the slow thinking and understand the situation.”
  • Thousands of us are less afraid than we were at the pandemic’s outset, even though in many parts of the country mounting case counts have increased the danger of getting the virus. We’re swarming the beaches and boardwalks, often without masks.

What Does It Mean to Have OCD? These Are 5 Common Symptoms | TIME - 0 views

  • Since absolute certainty is rarely possible, almost no reassurance clears the yes, but hurdle, and that keeps the anxiety wheels spinning.

      Lack of absolute certainty increases anxiety and doesn't let someone with OCD relax
  • It’s common for people with OCD to believe that if they check the stove just once more, or Google just one more symptom of a disease they’re convinced they’ve got, then their mind will be clear.
  • “The brain is conditioned to alert us to anything that threatens our survival, but this system is malfunctioning in OCD,” says psychologist Steven Phillipson, clinical director of the Center for Cognitive-Behavioral Psychotherapy in New York City. “That can result in a tsunami of emotional distress that keeps your attention absolutely focused.”

      The brain is trying to protect you but with OCD, it goes way overboard.
  • For the person with OCD, he explains, the brain is signaling what feels like a life and death risk, and it’s hard to put a price on survival.

  • “It’s the moment when a panic marries a concept,”

  • Eventually, Shlain, a filmmaker, extended the idea into a full day without screen use. She called it a tech shabbat — after the Jewish day of rest — and she has written several articles and a recent book, called “24/6,” about the idea.
  • “The digital revolution has blurred the lines between time on and time off, and time off is disappearing,” she wrote in The Boston Globe. “As for our leisure time, we’ve created a culture in which we’re still ‘working’ while we play: needing to photograph every moment, then crafting witty posts of our ‘fun, relaxing activities’ on Instagram, then obsessively checking responses. We can barely catch our breath in the tsunami of personal and work digital input, which results in us not being truly present for any of it.”
