    #100 - Sam Harris, Ph.D.: COVID-19—Comprehending the crisis and managing our emotions

    enMarch 24, 2020

    Podcast Summary

    • Learning from the COVID-19 CrisisThe COVID-19 pandemic highlights the importance of being better prepared for future crises, addressing global issues like climate change with urgency, and managing emotions and responses during uncertain times.

      The COVID-19 pandemic has brought unprecedented challenges to the world, and the discussion between Peter Atia and Sam Harris highlights the importance of learning from this experience and being better prepared for future crises. Despite the warnings and predictions, many people and governments seem to be underprepared and short-sighted, focusing on immediate needs rather than long-term solutions. The pandemic also underscores the need to address other global issues, such as climate change, with more foresight and urgency. As individuals, it's essential to manage our emotions and responses to the ongoing crisis and to use this time to reflect and learn. The discussion between Peter and Sam offers valuable insights into the current situation and the lessons we can take away.

    • Struggling with short-term sacrifices for long-term benefitsThe pandemic highlights our difficulty in prioritizing long-term benefits over short-term gains, with potentially disastrous consequences. Communicating uncertainty and the importance of taking action is challenging.

      As humans, we struggle with making short-term sacrifices for long-term benefits, as exemplified by the current pandemic situation. This problem is more pressing than climate change, which is still abstract and debatable, with disastrous consequences potentially within our lifetime. The speaker has experienced the challenge of convincing others to take the situation seriously, even among intelligent individuals with varying information diets, political convictions, economic biases, and incentives. Psychologically, the rapid passage of time and the blurring of days can make it difficult to grasp the gravity of the situation. Additionally, communicating uncertainty and error bars in projections is a challenge, as people tend to prefer clear, binary statements.

    • Understanding Probability and RiskAcknowledge uncertainty and potential errors in our thinking, consider using betting markets for sharper probability sense, and recognize differences between known and unknown risks.

      While it's convenient to use simple numbers and comparisons when discussing statistics, it's important to acknowledge the uncertainty and potential errors in our thinking. The speaker shares an example of how his personal experience with the flu and COVID-19 has influenced his perception, despite the flawed reasoning involved. He suggests that using betting markets or prediction markets could help sharpen our sense of probability and reduce alienation for those who are skeptical. The speaker also highlights the difference between known and unknown risks, using the example of influenza and COVID-19. While influenza is a known risk with a predictable wave and uniform mortality rate, COVID-19 is still in its infancy and exhibits nonlinear growth, making it difficult to determine the absolute potential for mortality. Therefore, it's crucial to recognize the limitations of our current knowledge and avoid making hasty comparisons or assumptions.

    • Comparing Income and Equity, Long-term Economic Impact of COVID-19Recognizing the complexity of an individual's financial situation and the long-term consequences of COVID-19 beyond immediate economic damage are crucial for effective response.

      The value of an individual's financial situation can be complex and not solely determined by current income. The example given was the comparison between an employee earning $100,000 a year and someone earning $10,000 a year but holding significant equity in a company. The value of that equity could potentially outweigh the income difference. Similarly, the impact of the COVID-19 pandemic extends beyond just the number of lives lost and the immediate economic damage. The long-term consequences, such as potential loss of social cohesion and economic depression, are also significant concerns. The challenge is to find ways to address these issues without causing further global economic harm. It's important to acknowledge the potential severity of the economic impact, but also to recognize that there is real value in taking action to contain the spread of the virus and prevent further damage. The comparison to the flu and the belief that the virus will simply peter out on its own is not supported by the evidence and could lead to disastrous consequences.

    • Finding the Balance Between Public Health and Societal Well-beingThe COVID-19 response requires balancing public health and societal well-being, with a brief total lockdown being a potential solution but politically unfeasible in some countries.

      The ongoing debate around the appropriate response to the COVID-19 pandemic involves a trade-off between public health and economic and societal well-being. Some argue for achieving herd immunity through allowing the virus to spread, while others advocate for strict lockdowns to contain it. The influenza analogy, often used to downplay the severity of COVID-19, is not a perfect comparison due to the potential for catastrophic consequences and the non-linearity of the situation. The challenge lies in finding the right balance between addressing the health crisis and minimizing the societal and economic impact of the measures taken. The speaker suggests that a brief, total lockdown could effectively stop the spread of the virus, but implementing this in a free society like the United States seems politically unfeasible. The communication of this scientific solution has been lacking, as people are concerned about the economic and societal consequences of a prolonged shutdown.

    • COVID-19's impact varies by cityUnderstanding a city's unique characteristics and using data-driven policies could lead to better COVID-19 outcomes. Milan's experience with 40x more deaths per capita than Sicily warns of potential New York trajectory.

      The COVID-19 pandemic is not affecting every city or region uniformly, and a more nuanced approach to policymaking, based on each city's unique characteristics, may have been more effective in containing the spread. The speaker uses the example of Italy, where mortality rates vary significantly between cities, with Milan experiencing 40 times more deaths per capita than Sicily. This observation is particularly relevant to New York, which is currently experiencing a surge in cases and may be following a similar trajectory to Milan rather than South Korea's successful containment. The speaker also emphasizes the importance of understanding the unknown positives in New York, which could be in the hundreds of thousands based on modeling and historical data, and the need for more sophisticated modeling techniques to accurately predict the future spread of the virus. In summary, a more granular and data-driven approach to policymaking could have led to better outcomes in managing the COVID-19 pandemic.

    • New York City's High COVID-19 Cases: Population Density, Urban Living Conditions, Subway System, and Bad LuckNew York City's high number of COVID-19 cases is due to its dense population, urban living conditions, subway system, and an early outbreak. Estimates suggest up to 50,000 infected individuals, with around 1,500 to 2,000 needing ICU care. Hospitals can add 2,000 beds, but not all can be dedicated to COVID-19 patients.

      New York City's high number of COVID-19 cases can be attributed to a combination of factors including population density, urban living conditions, a subway system, and bad luck. The city had a bad head start in the outbreak and the perfect storm of these factors led to a larger number of infections compared to other cities. The most conservative estimate suggests there could be 50,000 infected individuals in New York City, with 1,500 to 2,000 requiring ICU care. The availability of ICU beds is a concern, with only around 1,000 beds in New York City and its surrounding areas, but hospitals can repurpose an additional 2,000 beds. However, it's important to note that non-COVID patients still require ICU care, so only a portion of the beds can be dedicated to COVID-19 patients.

    • Pressure on healthcare systems during COVID-19 pandemic4% of COVID-19 infected individuals may require ICU care, which translates to over 2000 beds needed in New York alone. Delayed care for non-COVID conditions could further strain healthcare systems.

      The ongoing COVID-19 pandemic is putting immense pressure on healthcare systems, particularly in cities like New York, and it's crucial to make conservative estimates when planning for ICU bed needs. For instance, if just 4% of the estimated 50,000 infected individuals in New York require ICU care, it would mean over 2000 beds are needed. Moreover, the potential increase in non-COVID-related conditions going untreated due to patients avoiding hospitals and delayed care should also be considered. The speaker shared personal examples, such as delayed dental procedures and vaccinations, and the risk of accidents or injuries. It's essential to consider these factors to prevent overwhelming healthcare systems and ensure proper care for all patients.

    • Cultivate mindfulness to reduce anxietyMindfulness practice helps reduce anxiety by focusing on present moment and letting go of negative thoughts without judgment or reaction, leading to increased agility in dealing with emotions and less suffering.

      Developing mindfulness, or clear attention to the present moment, can help reduce the impact and duration of unpleasant thoughts and emotions, such as anxiety. This skill is not an easy one to master, but with consistent practice, it becomes easier to observe and let go of negative thoughts without judgment or reaction. The goal is not to eliminate emotions entirely, but to become more agile in dealing with them, allowing them to pass through without causing unnecessary suffering. Mindfulness is not a mystical concept, but a simple practice of non-distracted, non-reactive attention to the present experience. By focusing on the physical sensations of anxiety, rather than the psychological content, its power can be diminished. It's important to remember that mindfulness is a skill that requires consistent practice, and it's okay if progress is not immediate. The key is to keep trying and to be patient with yourself as you learn to navigate the complexities of the human mind.

    • Recognize when anxiety serves no further purposeAnxiety and negative emotions can hinder us in the present moment. Once we've taken necessary action, it's important to release the anxiety and focus on the present.

      While fear and other negative emotions can serve a purpose, most of the time they don't and can hinder our ability to appreciate the present moment. Anxiety, for instance, can be useful in uncertain situations as it prompts us to take action. However, once we've figured out what we need to do, the anxiety serves no further purpose and should be released. The speaker emphasizes that most negative emotions are not based on reality but rather on our thoughts and fears about the future. Therefore, it's essential to recognize when the anxiety is pointless and let it go. The speaker also reflects on how his fear of uncertainty has impacted him during the COVID-19 pandemic, leading him to appreciate the value of staying at home despite his dislike of traveling.

    • Finding Silver Linings in Challenging TimesAmidst hardships, people discover unexpected joys like family time, new value systems, and appreciating life's simplicity. Coping with setbacks and helping kids navigate anxieties requires honesty and open communication.

      Despite the challenges and hardships brought about by the current circumstances, many people are finding unexpected silver linings. These include spending more time with family, discovering new value systems, and appreciating the simplicity of life. For some, the shift to working from home has been seamless, while others have faced significant financial and career setbacks. Regarding children, honesty and open communication are key to helping them navigate their anxieties. The speaker, who is generally calm and collected, has experienced some irritability and anxiety during this time but has found ways to cope. Overall, the experience has highlighted the importance of resilience, adaptability, and the value of human connection.

    • Mindfulness practices help individuals become more aware and detach from negative emotionsMindfulness practices, such as meditation, help individuals recognize the transient nature of consciousness and the illusory nature of the self, allowing for calm and effective responses to situations, even during disagreements and uncertain decisions.

      Mindfulness practices, such as meditation, can help individuals become more aware of and detach from negative emotions, allowing them to respond to situations more calmly and effectively. This doesn't mean suppressing emotions or bearing down on oneself, but rather recognizing the transient nature of consciousness and the illusory nature of the self. Even in the midst of strong emotional reactions, one can gain a sense of freedom and detachment, which can lead to more productive communication and problem-solving in relationships. However, disagreements and decisions about uncertain situations can be particularly stressful and may trigger strong emotional reactions. In these cases, it's important to stay focused on the problem at hand and be open to each other's perspectives, rather than getting caught up in the emotional contagion of the moment. Ultimately, the goal is to maintain a sense of calm and clarity, even in the face of uncertainty and disagreement.

    • Managing Emotions for Personal GrowthFind a supportive partner, reflect on past experiences, practice mindfulness, and set realistic expectations to manage emotions during high-pressure situations and promote personal growth.

      Understanding and managing emotions, especially during high-pressure situations, is crucial for personal growth and effective problem-solving. The speaker shared how his anxiety and shame can get the best of him when faced with seemingly insurmountable problems or when met with resistance from others. He emphasized the importance of finding a supportive spouse or partner who can help him navigate these emotions and maintain a sense of calm under pressure. The speaker also highlighted the importance of reflection and learning from past experiences to prevent getting stuck in unproductive emotional cycles. Additionally, he shared how mindfulness practices and setting realistic expectations can help manage emotions and prevent explosive reactions. Overall, the conversation underscored the importance of emotional intelligence and self-awareness in navigating life's challenges.

    • Mindfulness and Communication in RelationshipsEffective communication and mindfulness are crucial for managing emotions and relationships, especially during challenging situations. Apologizing sincerely and taking a moment to breathe and reflect before reacting can help strengthen bonds and teach valuable lessons to children.

      Effective communication and mindfulness are essential in managing emotions and relationships, especially during challenging situations with loved ones. The speaker's experience highlights the importance of taking a moment to breathe and reflect before reacting, as well as apologizing sincerely when mistakes are made. He also emphasizes the value of having a supportive partner who can provide guidance and encouragement in practicing mindfulness and emotional intelligence. Moreover, the speaker believes that even in moments of shame or embarrassment, there is an opportunity for growth and repair, making apologies a powerful tool for strengthening relationships and teaching valuable lessons to children. Ultimately, the speaker's perspective underscores the significance of mindfulness and communication in fostering healthy, loving relationships and personal growth.

    • The Dangers of Shame and the Importance of Recognizing ExpertiseShame can hinder accountability and ethical behavior, while denigrating expertise can lead to harmful decisions. Prioritize science, data, and knowledge, and acknowledge the constructive role of emotions.

      The toxic emotion of shame, while not always inappropriate, can be detrimental if not addressed, potentially leading to a dangerous lack of accountability and ethical behavior. This issue is further compounded by the current trend of denigrating expertise and knowledge in favor of uninformed opinions. It's important to recognize the value of science, data, and real knowledge, and to strive for a future where these foundational principles are prioritized. Additionally, practicing mindfulness and acknowledging the constructive role of emotions like anxiety and fear can help individuals navigate difficult emotions and make progress towards personal growth.

    • Government's crucial role in local crisesEffective crisis response requires government involvement, decentralization, learning from mistakes, and accountability.

      The role of government in addressing crises, such as pandemics, cannot be underestimated. While the private sector has its merits, certain crucial functions are best handled by the government. This is especially true during local crises where the response can be more effective if cities take on more risk stratification and planning. Decentralization and flexibility are essential, and it's crucial to learn from the mistakes made during the current crisis. Political controversies should not hinder effective problem-solving, and holding countries accountable for practices that lead to crises is a necessary part of self-preservation.

    • Exposing the need for global collaboration and transparencyThe COVID-19 pandemic highlights the importance of global cooperation and transparency from governments, while avoiding racial bias towards Chinese people.

      The COVID-19 pandemic, originating in China, has exposed the need for global collaboration and transparency from authoritarian governments. The virus is now global and it's essential to address the root causes while avoiding racial animus towards Chinese people. The scientific community is working on vaccines and therapies, but it may take time and come with risks. The prospects of creating an effective and safe vaccine for COVID-19 are challenging due to its nature and the risks associated with vaccination. Despite these challenges, it's crucial to remain optimistic and continue the research to mitigate the impact of future pandemics. The political and journalistic communities need to navigate complex issues, such as China's role and the potential for a vaccine, with nuance and accuracy.

    • Focus on clear safety profiles from large clinical trialsMaintain a nuanced discussion on vaccines, acknowledging real concerns while debunking false information, and making informed decisions based on accurate information.

      The discussion around vaccines should focus on clear safety profiles from large clinical trials, acknowledging the legitimate risks while avoiding false or misleading information. The fear of unknowns, such as the debunked claim that vaccines cause autism, should be distinguished from real concerns about vaccine safety. It's essential to have a sophisticated conversation about risk, considering the micro mortality points and acceptable levels of risk for various activities, including vaccinations. We owe it to ourselves to approach this topic with nuance and acknowledge that the answers may not always seem rational due to emotional biases. Ultimately, it's crucial to make informed decisions based on accurate information and a deep understanding of the risks and benefits involved.

    • Understanding human psychology in public policyAcknowledge psychological aspects, make evidence-based info actionable, stay informed, and adapt understanding

      Navigating human psychology is crucial in implementing effective public policy, particularly when it comes to assessing and addressing risks. For instance, while flying is statistically safer than driving, people's fear of flying can influence policy decisions. It's essential to acknowledge these psychological aspects and find ways to make evidence-based information actionable. The ongoing conversation between experts, like the one between Sam and Peter, can help us process new information and respond appropriately. Staying informed and open to new insights is vital, as the situation may change, and we might need to revisit discussions to adapt our understanding.

    In this “Ask Me Anything” (AMA) episode, Peter delves into the often misunderstood concept of inflammation. He first defines inflammation and differentiates between acute inflammation and chronic inflammation, the latter of which is linked to aging and a plethora of age-related diseases. Peter breaks down the intricate relationship between chronic inflammation, obesity, and metabolic health, and highlights the signs that might suggest someone may be suffering from chronic inflammation. From there, the conversation centers on actionable advice and practical steps one can take to manage and minimize chronic inflammation. He explores how diet plays a crucial role, including the potential benefits of elimination diets, and he examines the impact of lifestyle factors such as exercise, sleep, and stress management. Additionally, he discusses the relevance of food inflammatory tests and concludes by examining the potential benefits and drawbacks of drugs and supplements in managing inflammation.
