    Podcast Summary

    • Trusting Efficient Platforms for Hiring and Personal FinancesUtilize Indeed for hiring and Rocket Money for personal finances to save time and maximize results. Understand moral reasoning frameworks for ethical dilemmas and effective charitable giving.

      When it comes to hiring or managing your personal finances, it's not about constantly searching for the best options, but rather utilizing efficient and effective platforms. For hiring, Indeed is a valuable resource with over 350 million monthly visitors and a matching engine that helps you find quality candidates quickly. Instead of wasting time and energy on searching, trust Indeed to streamline the process and deliver high-quality matches. Similarly, for managing personal finances, Rocket Money is an app that helps you cancel unwanted subscriptions, monitor spending, and lower bills, saving users an average of $720 per year. By using these platforms, you can focus on your core tasks and let the experts handle the rest. Additionally, the trolley problem, a philosophical thought experiment, highlights the competition between deontological and consequentialist moral reasoning. Understanding how our brains process these moral frameworks can lead to deeper insights into personal and global ethical dilemmas. Furthermore, charitable giving can benefit from this knowledge through programs like Giving Multiplier, which allows donors to support both personal and effective altruist charities while receiving a higher match rate for their donations. Overall, trusting efficient platforms and gaining a deeper understanding of moral reasoning can lead to significant improvements in various aspects of life.

    • The Evolutionary Basis of MoralityMorality arises from emotional responses and drives cooperative behavior, but the challenge is for groups with differing interests and values to coexist.

      Morality is a natural phenomenon that arises from evolution and cooperation among organisms. It is driven by emotional responses, such as empathy, compassion, anger, and disgust, which act as carrots and sticks for individuals and groups to engage in cooperative behavior. However, while this explains why humans behave morally, it does not necessarily dictate that they should. The fundamental moral problem for individuals is selfishness versus caring about others, but in modern society, the challenge is for groups with differing interests and values to coexist. To address this higher-level moral problem, we need to find solutions that enable cooperation between groups. This conversation with Joshua Green explored the philosophical foundations of morality and ethics from an evolutionary perspective.

    • Recognizing the Equal Importance of All ExperiencesUtilitarianism emphasizes the importance of considering the quality of experiences for all beings capable of feeling pleasure or pain, leading to fair decisions and advocacy for animal rights, early opposition to slavery, and early defenses of gay rights.

      The quality of experience provides a common currency of value for resolving differences between groups with diverse values and interests. Utilitarianism, a consequentialist ethical theory, emphasizes this insight by arguing that everyone's experiences matter equally, regardless of species or human distinctions. By focusing on the quality of experiences, we can make fair and reasonable decisions that consider the impact on all beings capable of experiencing pleasure or pain. This perspective, which was quite revolutionary in the 19th century, led utilitarians to advocate for animal rights, early opposition to slavery, and even early defenses of gay rights. Ultimately, the metamorality that enables larger, more complex, and cooperative groups to live together productively is the recognition that all experiences matter equally.

    • Deep Pragmatism: An Ethical Approach to Minimize Suffering and Maximize Well-BeingDeep pragmatism prioritizes minimizing suffering and maximizing well-being for all sentient beings, acknowledges human limitations and biases, and values all experiences and consciousness equally.

      The ethical approach of deep pragmatism, which prioritizes minimizing suffering and maximizing well-being for all sentient beings, can be seen as an evolved form of utilitarianism. However, deep pragmatism acknowledges the limitations and biases in human nature, and recognizes that sacrificing individual lives for the greater good is not an acceptable solution. Instead, deep pragmatists focus on evidence-based decision-making and working within the constraints of human nature while striving for a higher ideal. This approach also values the experiences and consciousness of all beings equally. The speaker emphasizes the importance of understanding the biases and limitations in human nature to avoid the pitfalls of utilitarianism, while acknowledging that trade-offs may be necessary in certain situations. The use of the Babbel language learning app as an example illustrates the practical application of deep pragmatism in daily life.

    • Understanding Different Ethical SystemsUtilitarianism prioritizes the greatest good, deontology follows moral rules, and virtue ethics cultivates virtues. Each system has merits and limitations, requiring careful consideration of context and implications.

      While utilitarianism, an ethical system that prioritizes the greatest good for the greatest number, can lead to morally justifiable decisions in extreme situations, it's important to be cautious in applying it in everyday life. Utilitarianism can be contrasted with other ethical systems, such as deontology and virtue ethics. Deontology, which emphasizes following moral rules regardless of consequences, can be seen as a rationalization of moral emotions. Virtue ethics, which focuses on cultivating virtues to live a good life, lacks a clear answer on specific moral dilemmas and can lead to debates about whose virtues are the correct ones. Ultimately, each ethical system has its merits and limitations, and it's essential to consider the context and implications of each approach.

    • Emotions play a significant role in moral dilemmasPeople's emotional responses to moral dilemmas, such as the trolley problem and footbridge case, are influenced by factors beyond logic and rationality, and these feelings may not generalize well to other situations.

      The emotional response to moral dilemmas, like the trolley problem, is driven by factors beyond just logic and rationality. The footbridge case, where people are asked whether it's ethical to push someone off a bridge to save five lives, elicits a stronger negative emotional response due to the active and direct nature of the action, as opposed to turning a trolley away from five people and onto one. This emotional response is rooted in our learning experiences and the basic mechanisms of reinforcement learning. However, philosophically, these feelings are not infallible and may not generalize well to other situations. In the case of Facebook and its failure to prevent the spread of misinformation and violence, the consequences are significant but the actions required to address them lack the same emotional charge, making it a more challenging moral dilemma. Overall, this research highlights the complex interplay between emotions, rationality, and moral decision-making.

    • Understanding the complexities of moral judgmentMoral philosophy offers guidance but not definitive answers, emotions influence moral judgments, and moral reasoning can be shaped by habits or conscious understanding.

      Moral philosophy, particularly deontology and consequentialism, while useful in everyday life, cannot provide definitive answers to complex moral dilemmas due to varying intuitions and interests among individuals and groups. Instead, deep pragmatism suggests acknowledging and understanding our feelings while being able to transcend them when necessary. From an empirical perspective, research shows that our moral judgments are influenced by emotions, specifically feelings of aversion or approval, which are linked to the amygdala in the brain. Additionally, our moral reasoning can be shaped by habits or a conscious understanding of rules and consequences, as evidenced in studies using navigation games. Ultimately, understanding the neurobiological underpinnings of moral judgment can provide valuable insights into the complex interplay of emotions, intuition, and reasoning in moral decision-making.

    • The Brain's Role in Moral Decision MakingOur moral decisions are influenced by a complex interplay between various brain regions, including the vmpfc, amygdala, and dorsal lateral prefrontal cortex. Emotions and rational thinking work together in morality fast and slow systems, and both involve evaluation and attachment of values to outcomes.

      Our moral decisions are not just driven by emotions or rational thinking in isolation, but rather by a complex interplay between various brain regions and systems. The ventromedial prefrontal cortex (vmpfc), which is linked to Phineas Gage's famous case of moral character change, acts as a hub for decision-making signals from different brain regions like the amygdala and dorsal lateral prefrontal cortex. These signals can be influenced by pharmacological interventions or brain damage, leading to different patterns of moral judgment. This concept is similar to Daniel Kahneman's thinking fast and slow dichotomy, where system 1 represents unconscious, automatic processing, and system 2 represents deliberative, rational thinking. In the context of morality, we can refer to this as morality fast and slow. The distinction between model-free learning and decision-making and model-based learning and decision-making, which is crucial in computer science and artificial intelligence, also applies to this dual process of morality. Both systems involve some kind of evaluation, with system 2 requiring the attachment of values to the outcomes of our decisions. Emotions play a role in both systems, but the fundamental distinction lies in whether we are reacting to the value of the immediate action or the value of the ultimate goal.

    • Moral intuitions vs complex moral issuesTrust moral intuitions in everyday life, but think deeply and critically for complex moral dilemmas using a pragmatic approach like utilitarianism.

      Our moral intuitions, or quick moral reactions, are useful in everyday life for guiding our actions and making basic decisions about right and wrong. However, when it comes to complex, intertribal moral issues that divide us, relying solely on our feelings can lead to conflict and even disaster. In these situations, it's necessary to think more deeply and critically about our moral beliefs and consider the consequences of our actions. Utilitarianism, which emphasizes the importance of maximizing overall happiness and minimizing suffering, can provide a useful framework for making moral decisions in these complex situations. However, it may not always align with our moral intuitions or quick reactions. In practice, a pragmatic approach might involve establishing a set of rules or guidelines that promote the greatest good for the greatest number, even if they don't perfectly align with our feelings. Ultimately, the goal is to find a balance between trusting our intuitions in everyday life and thinking more deeply and critically when faced with complex moral dilemmas.

    • Questioning everyday rules and habits for global impactWe must challenge our ingrained behaviors and consider their impact on larger global issues, prioritizing long-term consequences over immediate feelings or individual gain.

      Our everyday rules and habits, including those related to gender roles and food choices, should be open to questioning and reconsideration in light of their impact on larger global issues. The metaphor of the tragedy of the commons illustrates how our basic feelings and behaviors that help us live sustainably in small communities don't easily translate to addressing complex global problems. These problems require us to make choices that prioritize long-term consequences over immediate feelings or individual gain. The evolutionary ladder analogy emphasizes that we have the capacity to evolve beyond our initial instincts and values, but we must be intentional and thoughtful in doing so. Experimental studies, such as the public goods game, demonstrate the challenges of collective action and the importance of understanding and addressing the underlying motivations and incentives that shape our behavior.

    • Time pressure and cooperation with strangersPeople's behavior towards cooperation with strangers under time pressure can differ based on cultural experiences and social contexts. Trust and creating natural social structures are essential for building a more cooperative global society.

      Time pressure can influence people's behavior towards cooperating with strangers in a public good situation. However, this response can vary greatly depending on cultural experiences and social contexts. Some people may cooperate more under time pressure due to a dominant response to be cooperative, while others may punish cooperators due to a lack of trust and resentment of coercion. To build a more cooperative global society, it's essential to earn trust and create social structures that make cooperation feel natural. In simpler terms, when it comes to daily interactions, trust your gut reactions and be generous. But in larger, more complex situations, it's necessary to think more critically and consider different versions of prosociality. This concept of "us versus them" is deeply rooted in our evolutionary history and plays a significant role in shaping our behavior towards cooperation and competition.

    • The Instinct to Belong and Form CommunitiesOur instinct to belong can lead to both division and unity, with the potential for hierarchy and competition fueling the rise of authoritarian leaders. Finding a balance between inclusivity and exclusivity, and addressing economic inequality, are crucial for building stronger, more resilient communities.

      Humans have an inherent instinct to belong to groups and protect them, which can manifest as tribalism and ethnic nationalism. This instinct, which may have roots in our primate ancestors, can lead to division and conflict, but also offers cultural flexibility, allowing us to form larger communities. However, the possibility of hierarchy and competition for power can create incentives to defect at the cultural level, leading to the rise of authoritarian leaders who exploit fears and uncertainties to gain support. The challenge we face today is finding a balance between forming larger, more inclusive communities and fragmenting into smaller, more exclusive ones. Additionally, economic inequality and feelings of being left behind can contribute to the appeal of authoritarianism and nationalist movements.

    • Expand moral circles, be less selfish and tribalisticStrive for gradual improvement in global prosocial behavior, recognizing the interconnectedness of the world and the need for cooperation

      While it's natural for humans to prioritize those close to them, it's important to expand our moral circles and care for people beyond our immediate community. However, expecting people to care equally for all strangers may be unrealistic. Instead, we should aim to be less selfish and tribalistic, and gradually increase our global prosocial behavior. This can be compared to personal growth, where we don't expect to be perfect from the start but focus on making small improvements. The philosopher Aristotle also emphasized the importance of practice and gradual progress. Additionally, the complexities of modern supply chains, as illustrated by the example of a Scottish fish being filleted in China, highlight the interconnectedness of the world and the need for global cooperation.

    • Bridging Divides: The Importance of Understanding Our Interconnected WorldThrough cooperation and learning, we can bridge divides and make informed choices that align with our values, leading to a more interconnected and positive world.

      As our world becomes more interconnected and complex, it can be easy for us to become disconnected from the people and processes behind the things we consume. This can lead to moral blind spots, where we're not aware of the impact of our choices on others. However, research shows that when people from different backgrounds work together and cooperate, they can become more friendly and trusting of each other. Therefore, it's important for us to find ways to bridge these divides and make informed choices that align with our values. This might involve learning more about the origins of the things we buy, volunteering in our communities, or supporting organizations that promote social justice. By taking small steps to deepen our connections and understand the world around us, we can become better global citizens and make a positive impact on the world.

    • Supporting effective charities can make a big impact for little moneyEffective charities can prevent blindness for $100 vs $50k for a guide dog in US. Giving multipliers allow splitting donations, increasing effective charity funds.

      Individuals can do a lot of good with their resources by supporting highly effective charities, which can make a huge impact on people's lives for very little money. For example, the cost of preventing someone from going blind from trachoma is only $100, compared to the cost of helping a blind person in the US with a guide dog, which is $50,000. Charities like GiveWell, which pioneered effectiveness research, can help us identify these opportunities. However, convincing people to give to these charities instead of their preferred ones has proven to be challenging. A more effective approach is to allow people to split their donations between their preferred charity and a highly effective one. This approach, called "giving multipliers," has been found to result in more money going to the highly effective charity than if people were asked to give to it exclusively. This strategy seems to appeal to people's desire to balance their emotional connection to a charity with their rational desire to be effective and competent in doing good.

    • Supporting favorite charities and effective onesDonors can allocate funds to both personal favorite charities and effective ones recommended by experts, with the option to pay matching funds for others, encouraging effective giving and impactful donations.

      The Giving Multiplier platform allows donors to support both their personal favorite charities and highly effective charities recommended by experts, while also having the option to pay matching funds for others. The platform, which has raised over half a million dollars in less than a year, offers different charities covering various causes, all of which have been rigorously tested for effectiveness. Donors can decide how much they want to allocate to their personal favorite charity versus the recommended charities, with a minimum of 10% going to the recommended ones. The platform offers a 50% match for donations to the highly effective charity and a 25% match for split donations. This virtuous circle of effective giving has been self-sustaining, with many donors choosing to donate part of their donation to the matching fund to help others. The platform encourages donors to support causes they care about while also making a significant impact on the world.

    • Expanding the scope of charitable giving with matching fundsMatching funds allow donors to make a larger impact and create a cycle of giving that benefits both the cause and the donor.

      Effective altruism encourages individuals to expand the scope of their charitable giving through the use of matching funds. This approach allows people to make a larger impact while still feeling connected to the causes they support. The effectiveness of this method is not contingent on one's philosophical stance towards utilitarianism. By participating in a matching fund, donors become part of a cycle of giving that benefits both the cause and the donor. This discussion offers food for thought, inviting listeners to reflect on their own charitable practices and consider ways to increase their impact. Joshua Green, the guest on the Mindscape podcast, emphasized the importance of this approach and its potential to create a ripple effect of good.

    287 | Jean-Paul Faguet on Institutions and the Legacy of History

    One common feature of complex systems is sensitive dependence on initial conditions: a small change in how systems begin evolving can lead to large differences in their later behavior. In the social sphere, this is a way of saying that history matters. But it can be hard to quantify how much certain specific historical events have affected contemporary conditions, because the number of variables is so large and their impacts are so interdependent. Political economist Jean-Paul Faguet and collaborators have examined one case where we can closely measure the impact today of events from centuries ago: how Colombian communities are still affected by 16th-century encomienda, a colonial forced-labor institution. We talk about this and other examples of the legacy of history.

    286 | Blaise Agüera y Arcas on the Emergence of Replication and Computation

    Understanding how life began on Earth involves questions of chemistry, geology, planetary science, physics, and more. But the question of how random processes lead to organized, self-replicating, information-bearing systems is a more general one. That question can be addressed in an idealized world of computer code, initialized with random sequences and left to run. Starting with many such random systems, and allowing them to mutate and interact, will we end up with "lifelike," self-replicating programs? A new paper by Blaise Agüera y Arcas and collaborators suggests that the answer is yes. This raises interesting questions about whether computation is an attractor in the space of relevant dynamical processes, with implications for the origin and ubiquity of life.

    285 | Nate Silver on Prediction, Risk, and Rationality

    Being rational necessarily involves engagement with probability. Given two possible courses of action, it can be rational to prefer the one that could possibly result in a worse outcome, if there's also a substantial probability for an even better outcome. But one's attitude toward risk -- averse, tolerant, or even seeking -- also matters. Do we work to avoid the worse possible outcome, even if there is potential for enormous reward? Nate Silver has long thought about probability and prediction, from sports to politics to professional poker. In his his new book On The Edge: The Art of Risking Everything, Silver examines a set of traits characterizing people who welcome risks.

    284 | Doris Tsao on How the Brain Turns Vision Into the World

    The human brain does a pretty amazing job of taking in a huge amount of data from multiple sensory modalities -- vision, hearing, smell, etc. -- and constructing a coherent picture of the world, constantly being updated in real time. (Although perhaps in discrete moments, rather than continuously, as we learn in this podcast...) We're a long way from completely understanding how that works, but amazing progress has been made in identifying specific parts of the brain with specific functions in this process. Today we talk to leading neuroscientist Doris Tsao about the specific workings of vision, from how we recognize faces to how we construct a model of the world around us.

    The philosophy of mathematics would be so much easier if it weren't for infinity. The concept seems natural, but taking it seriously opens the door to counterintuitive results. As mathematician and philosopher Joel David Hamkins says in this conversation, when we say that the natural numbers are "0, 1, 2, 3, and so on," that "and so on" is hopelessly vague. We talk about different ways to think about the puzzles of infinity, how they might be resolved, and implications for mathematical realism.

    43 | Matthew Luczy on the Pleasures of Wine
    Some people never drink wine; for others, it’s an indispensable part of an enjoyable meal. Whatever your personal feelings might be, wine seems to exhibit a degree of complexity and nuance that can be intimidating to the non-expert. Where does that complexity come from, and how can we best approach wine? To answer these questions, we talk to Matthew Luczy, sommelier and wine director at Mélisse, one of the top fine-dining restaurants in the Los Angeles area. Matthew insisted that we actually drink wine rather than just talking about it, so drink we do. Therefore, in a Mindscape first, I recruited a third party to join us and add her own impressions of the tasting: science writer Jennifer Ouellette, who I knew would be available because we’re married to each other. We talk about what makes different wines distinct, the effects of aging, and what’s the right bottle to have with pizza. You are free to drink along at home, with exactly these wines or some other choices, but I think the podcast will be enjoyable whether you do or not. Support Mindscape on Patreon or Paypal. Mattew Luczy is a Certified Sommelier as judged by the Court of Master Sommeliers. He currently works as the Wine Director at Mélisse in Santa Monica, California. He is also active in photography and music. Mélisse home page Personal/photography page Instagram Ask a Somm: When Should I Decant Wine?

    255 | Michael Muthukrishna on Developing a Theory of Everyone

    A "Theory of Everything" is physicists' somewhat tongue-in-cheek phrase for a hypothetical model of all the fundamental physical interactions. Of course, even if we had such a theory, it would tell us nothing new about higher-level emergent phenomena, all the way up to human behavior and society. Can we even imagine a "Theory of Everyone," providing basic organizing principles for society? Michael Muthukrishna believes we can, and indeed that we can see the outlines of such a theory emerging, based on the relationships of people to each other and to the physical resources available.

    18 | Clifford Johnson on What's So Great About Superstring Theory
    String theory is a speculative and highly technical proposal for uniting the known forces of nature, including gravity, under a single quantum-mechanical framework. This doesn't seem like a recipe for creating a lightning rod of controversy, but somehow string theory has become just that. To get to the bottom of why anyone (indeed, a substantial majority of experts in the field) would think that replacing particles with little loops of string was a promising way forward for theoretical physics, I spoke with expert string theorist Clifford Johnson. We talk about the road string theory has taken from a tentative proposal dealing with the strong interactions, through a number of revolutions, to the point it's at today. Also, where all those extra dimensions might have gone. At the end we touch on Clifford's latest project, a graphic novel that he wrote and illustrated about how science is done. Clifford Johnson is a Professor of Physics at the University of Southern California. He received his Ph.D. in mathematics and physics from the University of Southampton. His research area is theoretical physics, focusing on string theory and quantum field theory. He was awarded the Maxwell Medal from the Institute of Physics. Johnson is the author of the technical monograph D-Branes, as well as the graphic novel The Dialogues.
