Is Our Planet Going the Way of the Dinosaurs?
We now think the big mass extinctions were caused by hydrogen sulfide bacteria. Two hundred hydrogen sulfide molecules among a million air molecules is enough to kill a human.
Most of the big mass extinctions have been caused by nasty volcanic events. The last one didn’t cause a mass extinction. It was in the Tertiary Period. This was in my own home state, Washington State, the Columbia River Basalts.
Out came all this basalt, as liquid lava, and a lot of the carbon dioxide came out too, but not enough to cause the Earth to go into a really nasty mass extinction. The mass extinctions caused by the basalts happen by simply heating the world. When you heat the world you heat the pole more than you do the equatorial region. When that happens, you start losing circulation. The only reason you have wind now is you have a hot spot and a cold spot and they’re trying to equilibrate. With an ocean current you have the same thing. You have a cold Antarctic and then you warm them up, the ocean circulation system is dampened down. There’s much less heat difference.
We already have very sluggish ocean circulation. The oceans are going oxic - losing their oxygen. They only keep oxygenated now because of this vigorous mixing. Even when you have oxygen in the atmosphere and contact with the surface, once you slow down any circulation, that whole basin can lose this oxygen. The Black Sea is the same case. It’s sits under a 21% oxygen atmosphere, and yet the Black Sea, except for the top several meters, in anoxic. It’s black because it’s producing a lot of sulfur-producing bacteria and there’s very nasty gasses that are produced.
We now think the big mass extinctions were caused by global anoxia. The oceans themselves were so sluggish that the hydrogen sulfide bacteria were produced in huge areas of the ocean. The bottom bubbles up to the surface and starts killing things - rotten egg killing. It would be extremely nasty. Hydrogen Sulfide poisoning is a horrible death. Two hundred hydrogen sulfide molecules among a million air molecules is enough to kill a human. Just breathing in 200 of those little things amid all the million you’re getting in oxygen and boom, you’re down, horribly down.
So, this is a really nasty poison and it was certainly present in past oceans during these short-term global warming events. That’s why it’s really spooky what we’re doing now.

COVID-19 amplified America’s devastating health gap. Can we bridge it?
The COVID-19 pandemic is making health disparities in the United States crystal clear. It is a clarion call for health care systems to double their efforts in vulnerable communities.

- The COVID-19 pandemic has exacerbated America's health disparities, widening the divide between the haves and have nots.
- Studies show disparities in wealth, race, and online access have disproportionately harmed underserved U.S. communities during the pandemic.
- To begin curing this social aliment, health systems like Northwell Health are establishing relationships of trust in these communities so that the post-COVID world looks different than the pre-COVID one.
<ul class="ee-ul"></ul>
<p>In the last 100 years, we've made incredible advances in health care, advances that would be viewed as miraculous to any previous generation. To pick one example, the<a href="https://ourworldindata.org/life-expectancy" target="_blank"> U.S. life expectancy</a> in 1950 was 68.2 years. We've since added 10 years to that average. Social programs have helped the young and elderly, two of the most health-vulnerable populations, receive unprecedented levels of care and attention. And telemedicine has decoupled many Americans' health support and monitoring from brick-and-mortar hospitals, expanding access to care.</p><p>Yet, despite these advances and despite handily<a href="https://www.brookings.edu/research/a-dozen-facts-about-the-economics-of-the-u-s-health-care-system/" target="_blank"> outspending other OECD nations on health care</a>, the United States preserves vast health disparities. As James Madara, CEO and executive vice president of the American Medical Association,<a href="https://www.ama-assn.org/about/leadership/america-s-health-care-crisis-much-deeper-covid-19" target="_blank" rel="noopener noreferrer"> </a>wrote on the organization's site: "The U.S. health system that exists today is a hodgepodge of ideas, programs, and regulations that is both extraordinarily expensive and highly inefficient. And despite its size and technological advancements, our health system is beset by tremendous gaps and inequities that favor some groups while unfairly disadvantaging others."</p><p>Our current predicament has its origins in tectonic sociohistorical forces that have shifted and fractured the health care landscape. For those at the peaks, access to superior care, education, resources, and social networks serve to protect their health. For those in the canyons, the ground continues to weather away with each past and ongoing crisis—consider, for example, the disproportionate fallout from<a href="https://diabetes.diabetesjournals.org/content/60/11/2667" target="_blank" rel="noopener noreferrer"> </a><a href="https://www.salon.com/2013/09/29/ronald_reagans_shameful_legacy_violence_the_homeless_mental_illness/" target="_blank" rel="noopener noreferrer">the dissolution of the Mental Health Systems Act</a>.</p><p>Then came COVID-19.</p>
COVID-19 deepens U.S. health disparities
<p>Communities on the pernicious side of America's health disparities have their unique histories, environments, and social structures. They are spread across the United States, but they all have one thing in common.</p><p>"There is one common divide in American communities, and that is poverty," said <a href="https://www.northwell.edu/about/leadership/debbie-salas-lopez" target="_blank">Debbie Salas-Lopez, MD, MPH</a>, senior vice president of community and population health at Northwell Health. "That is the undercurrent that manifests poor health, poor health outcomes, or poor health prognoses for future wellbeing."</p><p>Social determinants have far-reaching effects on health, and poor communities have unfavorable social determinants. To pick one of many examples, <a href="https://www.npr.org/2020/09/27/913612554/a-crisis-within-a-crisis-food-insecurity-and-covid-19" target="_blank" rel="noopener noreferrer">food insecurity</a> reduces access to quality food, leading to poor health and communal endemics of chronic medical conditions. The U.S. Centers for Disease Control and Prevention has identified some of these conditions, such as obesity and Type 2 diabetes, as increasing the risk of developing a severe case of coronavirus.</p><p>The pandemic didn't create poverty or food insecurity, but it exacerbated both, and the results have been catastrophic. A study published this summer in the <em><a href="https://link.springer.com/article/10.1007/s11606-020-05971-3" target="_blank">Journal of General Internal Medicine</a></em> suggested that "social factors such as income inequality may explain why some parts of the USA are hit harder by the COVID-19 pandemic than others."</p><p>That's not to say better-off families in the U.S. weren't harmed. A <a href="https://voxeu.org/article/poverty-inequality-and-covid-19-us" target="_blank" rel="noopener noreferrer">paper from the Centre for Economic Policy Research</a> noted that families in counties with a higher median income experienced adjustment costs associated with the pandemic—for example, lowering income-earning interactions to align with social distancing policies. However, the paper found that the costs of social distancing were much greater for poorer families, who cannot easily alter their living circumstances, which often include more individuals living in one home and a reliance on mass transit to reach work and grocery stores. They are also disproportionately represented in essential jobs, such as retail, transportation, and health care, where maintaining physical distance can be all but impossible.</p><p>The paper also cited a positive correlation between higher income inequality and higher rates of coronavirus infection. "Our interpretation is that poorer people are less able to protect themselves, which leads them to different choices—they face a steeper trade-off between their health and their economic welfare in the context of the threats posed by COVID-19," the authors wrote.</p><p>"There are so many pandemics that this pandemic has exacerbated," Dr. Salas-Lopez noted.</p><p>One example is the health-wealth gap. The mental stressors of maintaining a low socioeconomic status, especially in the face of extreme affluence, can have a physically degrading impact on health. <a href="https://www.scientificamerican.com/index.cfm/_api/render/file/?method=inline&fileID=123ECD96-EF81-46F6-983D2AE9A45FA354" target="_blank" rel="noopener noreferrer">Writing on this gap</a>, Robert Sapolsky, professor of biology and neurology at Stanford University, notes that socioeconomic stressors can increase blood pressure, reduce insulin response, increase chronic inflammation, and impair the prefrontal cortex and other brain functions through anxiety, depression, and cognitive load. </p><p>"Thus, from the macro level of entire body systems to the micro level of individual chromosomes, poverty finds a way to produce wear and tear," Sapolsky writes. "It is outrageous that if children are born into the wrong family, they will be predisposed toward poor health by the time they start to learn the alphabet."</p>Research on the economic and mental health fallout of COVID-19 is showing two things: That unemployment is hitting <a href="https://www.pewsocialtrends.org/2020/09/24/economic-fallout-from-covid-19-continues-to-hit-lower-income-americans-the-hardest/" target="_blank" rel="noopener noreferrer">low-income and young Americans</a> most during the pandemic, potentially widening the health-wealth gap further; and that the pandemic not only exacerbates mental health stressors, but is doing so at clinically relevant levels. As <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7413844/" target="_blank" rel="noopener noreferrer">the authors of one review</a> wrote, the pandemic's effects on mental health is itself an international public health priority.<blockquote>We need to find ways to unify this country because we're all human beings. We're all created equal, and we believe that health is one of those important rights.</blockquote>

<p>Novel coronavirus may spread and infect indiscriminately, but pre-existing conditions, environmental stressors, and a lack of access to care and resources increase the risk of infection. These social determinants make the pandemic more dangerous, and erode communities' and families' abilities to heal from health crises that pre-date the pandemic.</p><p>How do we eliminate these divides? Dr. Salas-Lopez says the first step is recognition. "We have to open our eyes to see the suffering around us," she said. "Northwell has not shied away from that."</p><p>"We are steadfast in improving health outcomes for our vulnerable and underrepresented communities that have suffered because of the prevalence of chronic disease, a problem that led to the disproportionately higher death rate among African-Americans and Latinos during the COVID-19 pandemic," said Michael Dowling, Northwell's president and CEO. "We are committed to using every tool at our disposal—as a provider of health care, employer, purchaser and investor—to combat disparities and ensure the <a href="https://www.northwell.edu/education-and-resources/community-engagement/center-for-equity-of-care" target="_blank" rel="noopener noreferrer">equity of care</a> that everyone deserves." </p><p>With the need recognized, Dr. Salas-Lopez calls for health care systems to travel upstream and be proactive in those hard-hit communities. This requires health care systems to play a strong role, but not a unilateral one. They must build <a href="https://www.northwell.edu/news/insights/faith-based-leaders-are-the-key-to-improving-community-health" target="_blank" rel="noopener noreferrer">partnerships with leaders in those communities</a> and utilize those to ensure relationships last beyond the current crisis. </p><p>"We must meet with community leaders and talk to them to get their perspective on what they believe the community needs are and should be for the future. Together, we can co-create a plan to measurably improve [community] health and also to be ready for whatever comes next," she said.</p><p>Northwell has built relationships with local faith-based and community organizations in underserved communities of color. Those partnerships enabled Northwell to test more than 65,000 people across the metro New York region. The health system also offered education on coronavirus and precautions to curb its spread.</p><p>These initiatives began the process of building trust—trust that Northwell has counted on to return to these communities to administer flu vaccines to prepare for what experts fear may be a difficult flu season.</p><p>While Northwell has begun building bridges across the divides of the New York area, much will still need to be done to cure U.S. health care overall. There is hope that the COVID pandemic will awaken us to the deep disparities in the US.</p><p>"COVID has changed our world. We have to seize this opportunity, this pandemic, this crisis to do better," Dr. Salas-Lopez said. "Provide better care. Provide better health. Be better partners. Be better community citizens. And treat each other with respect and dignity.</p><p>"We need to find ways to unify this country because we're all human beings. We're all created equal, and we believe that health is one of those important rights."</p>

Chernobyl fungus could shield astronauts from cosmic radiation
A recent study tested how well the fungi species Cladosporium sphaerospermum blocked cosmic radiation aboard the International Space Station.
03 August, 2020

Surprising Science
- Radiation is one of the biggest threats to astronauts' safety during long-term missions.
- C. sphaerospermum is known to thrive in high-radiation environments through a process called radiosynthesis.
- The results of the study suggest that a thin layer of the fungus could serve as an effective shield against cosmic radiation for astronauts.
<p>When astronauts return to the moon or travel to Mars, how will they shield themselves against high levels of cosmic radiation? A recent experiment aboard the International Space Station suggests a surprising solution: a radiation-eating fungus, which could be used as a self-replicating shield against gamma radiation in space.</p><p>The fungus is called <em>Cladosporium sphaerospermum</em>, an extremophile species that thrives in high-radiation areas like the Chernobyl Nuclear Power Plant. For <em>C. sphaerospermum</em>, radiation isn't a threat — it's food. That's because the fungus is able to convert gamma radiation into chemical energy through a process called radiosynthesis. (Think of it like photosynthesis, but swap out sunlight for radiation.)</p><p>The <a href="https://en.wikipedia.org/wiki/Radiotrophic_fungus#:~:text=Radiotrophic%20fungi%20are%20fungi%20which,into%20chemical%20energy%20for%20growth." target="_blank">radiotrophic fungus</a> performs radiosynthesis by using melanin — the same pigment that gives color to our skin, hair and eyes — to convert X- and gamma rays into chemical energy. Scientists don't fully understand this process yet. But the study notes that it's "believed that large amounts of melanin in the cell walls of these fungi mediate electron-transfer and thus allow for a net energy gain."</p>

Shunk et al.
<p>Additionally, the fungus is self-replicating, meaning astronauts would potentially be able to "grow" new radiation shielding on deep-space missions, instead of having to rely on a costly and complicated interplanetary supply chain.</p><p>Still, the researchers weren't sure whether <em>C. sphaerospermum</em> would survive on the space station. Nils J.H. Averesch, a co-author of the <a href="https://www.biorxiv.org/content/10.1101/2020.07.16.205534v1.full.pdf" target="_blank">study published on the preprint server bioRxiv</a>, told <a href="https://www.syfy.com/syfywire/fungus-that-eats-radiation-could-be-cosmic-ray-shield" target="_blank">SYFY WIRE</a>:</p><p style="margin-left: 20px;">"While on Earth, most sources of radiation are gamma- and/or X-rays; radiation in space and on Mars (also known as GCR or galactic cosmic radiation) is of a completely different kind and involves highly energetic particles, mostly protons. This radiation is even more destructive than X- and gamma-rays, so not even survival of the fungus on the ISS was a given."</p><img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzUzMDY2Mi9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY1NzM2MTk5OX0.9itVRaQ-O18I3xhLKLMV-TU9JPqGKUAcr2CRcOB0TEo/img.jpg?width=980" id="9c5dd" class="rm-shortcode" data-rm-shortcode-id="4bf6b4d563e31ec1427c5146680611b3" data-rm-shortcode-name="rebelmouse-image" alt="Fungus in dish" />
C. sphaerospermum
<p>To test the "radio-resistance" of <em>C. sphaerospermum</em> in space, petri dishes containing a .06-inch layer of the fungus were exposed to cosmic radiation aboard the ISS. Dishes containing no fungus were exposed, too. The results showed that the fungus cut radiation levels by about 2 percent.</p><p>Extrapolating these results, the researchers estimated that a roughly 8-inch layer of <em>C. sphaerospermum</em> "could largely negate the annual dose-equivalent of the radiation environment on the surface of Mars." That would be a significant benefit to astronauts. After all, an astronaut who is one year into a Mars mission would have been exposed to roughly 66 times more radiation than the average person on Earth.</p><img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMzUzMDY2My9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY1NzY3MzI0OH0.OKgKmgz2ffz7bCiU7B9Yeal_ia1wXPzcHZPOupZurGg/img.jpg?width=980" id="b07eb" class="rm-shortcode" data-rm-shortcode-id="9b0508619697790cb1e5ff2e4239d174" data-rm-shortcode-name="rebelmouse-image" alt="ISS" />
International Space Station
NASA
<p>To be sure, the researchers said more research is needed, and that <em>C. sphaerospermum</em> would likely be used in combination with other radiation-shielding technology aboard spacecraft. But the findings highlight how relatively simple biotechnologies may offer outsized benefits on upcoming space missions.</p><p style="margin-left: 20px;">"Often nature has already developed blindly obvious yet surprisingly effective solutions to engineering and design problems faced as humankind evolves – C. sphaerospermum and melanin could thus prove to be invaluable in providing adequate protection of explorers on future missions to the Moon, Mars and beyond," the researchers wrote.</p>

Bruce Lee: How to live successfully in a world with no rules ...
Videos
- Bruce Lee would have turned 80 years old on November 27, 2020. The legendary actor and martial artist's daughter, Shannon Lee, shares some of his wisdom and his philosophy on self help in a new book titled "Be Water, My Friend: The Teachings of Bruce Lee."
- In this video, Shannon shares a story of the fight that led to her father beginning a deeper philosophical journey, and how that informed his unique expression of martial arts called Jeet Kune Do.
- One lesson passed down from Bruce Lee was his use and placement of physical symbols as a way to help "cement for yourself this new way of being, or this new lesson you've learned." By working on ourselves (with the right tools), we can develop the skills necessary to rise and conquer new challenges.

3 reasons for information exhaustion – and what to do about it
How to deal with "epistemic exhaustion."
26 November, 2020
Photo by Filip Mishevski on Unsplash
Mind & Brain
An endless flow of information is coming at us constantly: It might be an article a friend shared on Facebook with a sensational headline or wrong information about the spread of the coronavirus.
<p> It could even be a call from a relative wanting to talk about a political issue. </p><p>All this information may leave many of us feeling as though we have no energy to engage. </p><p>As a <a href="https://clasprofiles.wayne.edu/profile/hf1190" target="_blank">philosopher</a> who studies <a href="https://philpeople.org/profiles/mark-satta" target="_blank">knowledge-sharing practices</a>, I call this experience “epistemic exhaustion." The term “epistemic" comes from the Greek word <a href="https://plato.stanford.edu/entries/epistemology/" target="_blank">episteme</a>, often translated as “knowledge." So epistemic exhaustion is more of a knowledge-related exhaustion.</p><p>It is not knowledge itself that tires out many of us. Rather, it is the process of trying to gain or share knowledge under challenging circumstances. </p><p>Currently, there are at least three common sources that, from my perspective, are leading to such exhaustion. But there are also ways to deal with them. </p>
<h2>1. Uncertainty</h2><p>For many, this year has been full of uncertainty. In particular, the <a href="https://journals.sagepub.com/doi/full/10.1177/0141076820930665" target="_blank" rel="noopener noreferrer">coronavirus pandemic</a> has generated uncertainty about health, about best practices and about the future.</p><p>At the same time, Americans have faced <a href="https://www.pewresearch.org/fact-tank/2020/10/07/voters-anxiously-approach-an-unusual-election-and-its-potentially-uncertain-aftermath/" target="_blank" rel="noopener noreferrer">uncertainty about the U.S. presidential election</a>: first due to delayed results and now over <a href="https://www.nytimes.com/2020/09/23/us/politics/trump-power-transfer-2020-election.html?searchResultPosition=3" target="_blank" rel="noopener noreferrer">questions about a peaceful transition of power</a>.</p><p>Experiencing <a href="https://www.apa.org/topics/stress-uncertainty" target="_blank" rel="noopener noreferrer">uncertainty can stress most of us out</a>. People tend to prefer the planned and the predictable. Figures from 17th-century French philosopher <a href="http://philsci-archive.pitt.edu/15537/1/Certainty%20and%20Explanation%20in%20Descartes%20HOPOS%20AcceptedFinal.pdf" target="_blank" rel="noopener noreferrer">René Descartes</a> to 20th-century Austrian philosopher <a href="https://www.goodreads.com/book/show/762159.On_Certainty" target="_blank" rel="noopener noreferrer">Ludwig Wittgenstein</a> have recognized the significance of having certainty in our lives.</p><p>With information so readily available, people may be checking news sites or social media in hopes of finding answers. But often, people are instead greeted with more reminders of uncertainty.</p>
<h2>2. Polarization</h2><p>Political polarization <a href="https://www.huffingtonpost.ca/robert-barrett-phd/the-stress-from-political-polarization-is-killing-us-slowly_a_23350469/" target="_blank" rel="noopener noreferrer">is stressing many Americans out</a>.</p><p>As political scientist <a href="https://gvpt.umd.edu/facultyprofile/mason/lilliana" target="_blank" rel="noopener noreferrer">Lilliana Mason</a> notes in her book, "<a href="https://press.uchicago.edu/ucp/books/book/chicago/U/bo27527354.html" target="_blank" rel="noopener noreferrer">Uncivil Disagreement: How Politics Became Our Identity</a>," Americans have been increasingly dividing politically "into two partisan teams."</p><p>Many writers have discussed the <a href="https://theconversation.com/extreme-political-polarization-weakens-democracy-can-the-us-avoid-that-fate-105540" target="_blank" rel="noopener noreferrer">negative effects of polarization</a>, such as how it can damage democracy. But discussions about the harms of polarization often overlook the toll polarization takes on our ability to gain and share knowledge.</p><p>That can happen in at least two ways.</p><p>First, as philosopher <a href="https://www.kevinvallier.com/" target="_blank" rel="noopener noreferrer">Kevin Vallier</a> has argued, there is a "<a href="https://www.kevinvallier.com/reconciled/low-trust-exacerbates-polarization/" target="_blank" rel="noopener noreferrer">causal feedback loop</a>" between polarization and distrust. In other words, polarization and distrust fuel one another. Such a cycle can leave people feeling <a href="https://news.gallup.com/opinion/gallup/284357/polarization-may-undermine-community-bonds-trust-others.aspx" target="_blank" rel="noopener noreferrer">unsure whom to trust or what to believe</a>.</p><p>Second, polarization can lead to <a href="https://time.com/5907318/polarization-2020-election/" target="_blank" rel="noopener noreferrer">competing narratives</a> because in a deeply polarized society, as studies show, we can <a href="https://www.degruyter.com/view/journals/for/16/1/article-p47.xml" target="_blank" rel="noopener noreferrer">lose common ground</a> and tend to have less agreement.</p><p>For those inclined to take the views of others seriously, this can create additional cognitive work. And when the issues are heated or sensitive, this can create additional <a href="https://www.sciencedaily.com/releases/2019/09/190926073348.htm" target="_blank" rel="noopener noreferrer">stress and emotional burdens</a>, such as sadness over damaged friendships or anger over partisan rhetoric.</p>
<h2>3. Misinformation</h2><p>Viral misinformation is everywhere. This includes <a href="https://iop.harvard.edu/get-involved/study-groups/propaganda-today%E2%80%99s-american-politics" target="_blank" rel="noopener noreferrer">political propaganda in the United States</a> and <a href="https://www.nytimes.com/2019/08/06/books/review/peter-pomerantsev-this-is-not-propaganda.html" target="_blank" rel="noopener noreferrer">around the world</a>.</p><p>People are also inundated with advertising and misleading messaging from private corporations, what philosophers <a href="http://cailinoconnor.com/" target="_blank" rel="noopener noreferrer">Cailin O'Connor</a> and <a href="http://jamesowenweatherall.com/" target="_blank" rel="noopener noreferrer">James Owen Weatherall</a> have called "<a href="https://heterodoxacademy.org/wp-content/uploads/2020/03/062_Cailin_oConnor_How_False_Beliefs_Spread.pdf" target="_blank" rel="noopener noreferrer">industrial propaganda</a>." And in 2020, the public is also dealing with <a href="https://www.nature.com/articles/d41586-020-01452-z" target="_blank" rel="noopener noreferrer">misinformation about COVID-19</a>.</p><p>As chess grandmaster <a href="https://twitter.com/kasparov63/status/808750564284702720?lang=en" target="_blank" rel="noopener noreferrer">Garry Kasparov put it</a>: "The point of modern propaganda isn't only to misinform or push an agenda. It is to exhaust your critical thinking, to annihilate truth."</p><p>Misinformation is often exhausting by design. For example, <a href="https://theconversation.com/coronavirus-plandemic-and-the-seven-traits-of-conspiratorial-thinking-138483" target="_blank" rel="noopener noreferrer">a video that went viral,</a> "<a href="https://www.forbes.com/sites/tarahaelle/2020/05/08/why-its-important-to-push-back-on-plandemic-and-how-to-do-it/?sh=3e430c9e5fa3" target="_blank" rel="noopener noreferrer">Plandemic</a>," featured a large number of false claims about COVID-19 in rapid succession. This flooding of misinformation in rapid succession, a tactic known as a <a href="https://www.vox.com/2016/9/26/13036258/donald-trump-debate-win-lies-preparation" target="_blank" rel="noopener noreferrer">Gish gallop</a>, makes it challenging and time-consuming for fact checkers to refute the many falsehoods following one after another.</p>
<h2>What to do?</h2><p>With all this uncertainty, polarization and misinformation, feeling tired is understandable. But there are things one can do.</p><p>The American Psychological Association suggests <a href="https://www.apa.org/topics/stress-uncertainty" target="_blank" rel="noopener noreferrer">coping with uncertainty</a> through activities like limiting news consumption and focusing on things in one's control. Another option is to work on becoming more <a href="https://pemachodronfoundation.org/product/comfortable-with-uncertainty-book/" target="_blank" rel="noopener noreferrer">comfortable with uncertainty</a> through practices such as meditation and the cultivation of mindfulness.</p><p>To deal with polarization, consider communicating with the goal of <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/phpr.12624" target="_blank" rel="noopener noreferrer">creating empathetic understanding</a> rather than "winning." Philosopher <a href="http://mjhannon.com/" target="_blank" rel="noopener noreferrer">Michael Hannon</a> describes empathetic understanding as "the ability to take up another person's perspective."</p><p>As for limiting the spread of misinformation: Share only those news stories that you've read and verified. And you can prioritize outlets that meet high ethical <a href="https://www.spj.org/ethicscode.asp" target="_blank" rel="noopener noreferrer">journalistic</a> or <a href="https://www.poynter.org/ifcn-fact-checkers-code-of-principles/" target="_blank" rel="noopener noreferrer">fact-checking standards</a>.</p><p>These solutions are limited and imperfect, but that's all right. Part of resisting epistemic exhaustion is learning to live with the limited and imperfect. No one has time to vet all the headlines, correct all the misinformation or gain all the relevant knowledge. To deny this is to set oneself up for exhaustion.<img src="https://counter.theconversation.com/content/149615/count.gif?distributor=republish-lightbox-basic" alt="The Conversation"></p><p><a href="https://theconversation.com/profiles/mark-satta-1173820" target="_blank">Mark Satta</a>, Assistant Professor of Philosophy, <em><a href="https://theconversation.com/institutions/wayne-state-university-989" target="_blank" rel="noopener noreferrer">Wayne State University</a></em></p><p>This article is republished from <a href="https://theconversation.com/" target="_blank" rel="noopener noreferrer">The Conversation</a> under a Creative Commons license.
