Terror Management Theory: How Existential Dread Has Shaped the World with Sheldon Solomon
Many of us wrestle with the unsettling truth that everyone – including ourselves and those we love – will one day die. Though this awareness is uncomfortable, research suggests that the human capacity to contemplate death is a byproduct of consciousness itself. In fact, our efforts to cope with mortality are at the core of culture, religion, the desire for wealth, and even many of today's societal crises. How might a deeper understanding of our implicit reactions to mortality help us turn towards responses that are more supportive of our species and planet? In this episode, Nate is joined by Sh...

The Three Most Important Words We're Taught Not to Say
In this week's Frankly, Nate considers the ways in which our social species overvalues false-confidence rather than the more honest and inquisitive response of "I don't know." He invites us to consider the science behind this cultural bias towards certainty: from our biological response from the stress of "not knowing" to the reinforcing effects of motivated reasoning that ensnares even the smartest among us (especially the smartest among us). Overconfidence and the desire for quick answers have been the root cause of many of humanity's disasters, from the space shuttle Challenger explosion to the Deep Water Horizon...

Challenging Monopoly Power: Why Local Business is Better for People, the Planet, and Your Wallet with Stacy Mitchell
Monopolistic business practices have been illegal in the United States for more than a century. Yet, monopoly power continues to accelerate in our modern commercial landscape. Large, powerful corporations edge out smaller businesses, often citing scale, "efficiency", and lower costs as their reasons for success. But looking more closely reveals a reality that is far different. Small businesses are more cost-effective and deliver better results to the people they serve than giant corporations. Furthermore, they form the backbone of engaged and connected communities. So what is actually preventing small businesses (and communities) from flourishing, and what can individuals do...

What Sloths Teach Us About the Superorganism
In this week's Frankly, Nate reflects on the multiple metaphors brought to mind via a single photograph, which depicts a sloth climbing a barbed wire fence in Costa Rica. Beyond evoking compassion for a species that's on the receiving end of human intervention into its ecosystem, the image raises larger ideas about the response of animals, including humans, to artificial cues and novel environments. Just as the sloth mistakes a fence post for the safety of a tree, modern humans mistake consumption, speed, and certainty for meaning. Moving beyond just the image, Nate unpacks the word "sloth"...

Will Coral Reefs Be Gone by 2050? How Bleaching, Acidification, and Ocean Heating are Killing Coral Reefs with Ove Hoegh-Guldberg
Twenty-five years ago, a landmark paper warned that the world's coral reefs could vanish by 2050. Now, halfway to that projected date (and amid ever more frequent coral bleaching events), that grim prediction feels increasingly close to reality. What is the current state of Earth's coral reefs, and what would happen to our planetary home without them? In this episode, Nate is joined by Ove Hoegh-Guldberg, the marine biologist who made this landmark prediction, for an update on the health of coral reefs and the primary ecological stressors driving their decline. Drawing on decades of research, he explains t...

Is the U.S. Electric Grid Stable? Policy, Renewables, and Who Is Responsible If The Grid Fails with Meredith Angwin
For many people in the modern world, electricity powers everything we do. Yet we take for granted how power flows in the background, seemingly always accessible to us just by flipping a switch. In fact, most of us are completely unaware of what it takes to generate and transmit the power we so deeply rely on, let alone the policy decisions shaping our electrical grids – or how they might affect reliable access to power. How do today's electrical grids actually work, and do they align with our long-term goals for human and planetary well-being? In this episode, Na...

Peak Oil, Ponzi Pyramids, and Planetary Boundaries
To view the graphs Nate is referring to in this episode, please click here. --- In this week's Frankly, Nate returns from New York City Climate Week with fresh reflections on the disconnect between our economic narratives and biophysical realities. Using his background in finance, Nate observes that while the prioritization of financial abstractions and claims continue to accelerate, with gold and silver prices reaching record-setting highs, the ledger is being balanced with parallel declines in our planetary health and social resilience. This tradeoff is harder and harder to ignore as newly crossed planetary boundaries...

Moral Ambition: Redefining Success for the Global Good with Rutger Bregman
The overarching definition of success today often looks like the accumulation of stuff – money, cars, property, clothing – anything that signals wealth. This means that success is also synonymous with overshoot, extraction, and consumption – none of which lead to healthy outcomes for the planet or the global good. But what might be possible if we were to redefine success to prioritize collective well-being instead of personal gain? In today's episode, Nate sits down with Dutch historian and author Rutger Bregman to discuss the concept of moral ambition, which he defines as the desire to be one of the best...

The Influence of Psychopaths: Why Humanity Is Better Than We Think
In this week's Frankly, Nate reflects on intraspecies predation (ours) and the impact psychopathic actors have on the mean and median of human behavior – in the past all the way up to our modern society. Human evolution was shaped by both cooperative, pro-social behavior and a competitive, predatory approach for survival – resulting in a balanced distribution for most of humanity's existence. But, as agriculture, surplus, and other factors propelled more hierarchical social structure, aggregate human behavior and culture has slowly shifted over time to express more psychopathic traits. This thread of behavior continues to run through our modern...

The Past and Future of Societal Collapse: Why Civilizations Fall and What We Can Learn From It with Luke Kemp
For many people today, the idea of societal collapse is unimaginable. Yet history shows that well-established civilizations have fallen again and again – often for similar reasons. In fact, the same forces that build empires can also culminate in their downfall. How can understanding these historical patterns help us prepare for similar existential risks we may already be facing today? In this episode, Nate is joined by existential risk researcher Luke Kemp to explore the intricate history of societal collapse – connecting patterns of dominance hierarchies, resource control, and inequality to create societies which he calls Goliaths. Together, they delve...

Dark Triad Personality Traits: How Psychopathy, Narcissism, and Machiavellianism Impact Our Cultures & Social Systems | RR 19
Psychopathy is often portrayed as a rare and distant phenomenon – something confined to movie villains or prison cells. Yet when psychopathy is combined with narcissism and Machiavellianism to form what psychologists call the Dark Triad, its impact becomes far more immediate. Individuals with these traits can wield disproportionate influence over our culture, institutions, and daily lives. What goes on inside their minds, and how do they shape the world around us? In this episode, Nate is joined by Dr. Reid Meloy and Dr. Nancy McWilliams to explore the inner workings of the Dark Triad personality traits and th...

Why We Need Forests: Their Vital Role in Climate Dynamics, Rain, and The Biotic Pump with Anastassia Makarieva
To best understand this episode, please watch this ~2 minute video on the biotic pump. It's widely known that Earth's forests provide home to countless numbers of species, act as a vast sink for carbon, and provide much of the food, materials, and clean water on which our societies rely. But emerging science shows us that forests may play another critical role: making rain. This theory, called the biotic pump theory, hypothesizes that instead of being passive recipients of rain, forests may actively create the conditions for precipitation over land – a premise that turns modern meteorology on...

10 Things Worth More Than a Pound of Gold | Frankly 106
In this week's Frankly, Nate weighs the value of a pound of gold with other things that we derive worth from in our lives – from dollars and bitcoin to...less pecuniary markers. Although gold is simply a metal, it has long been a symbol of wealth in human cultures. Through highlighting other important, sometimes intangible forms of wealth, Nate encourages the viewer to not only examine what they place the most worth on in their own lives, but also to consider why things have worth to us as humans living in a complex, modern system. What contributes to...

How Water Shapes Our Planet: The Undervalued Resource that Supports Everything We Do | Reality Roundtable 18
Water has always been a fundamental force shaping our planet – both in sustaining life across ecosystems and in guiding the organization and survival of human societies. Yet, many of us are unaware of how intertwined our lives are with the water cycle, much less of the ways we deplete and degrade the water resources that we and other living creatures rely upon for our very existence. What might change if we had a deeper understanding of global and regional hydrological cycles? On this Reality Roundtable, Nate is joined by Heather Cooley, Zach Weiss, and Mike Joy to dis...

Where Will Humanity Move When the World Gets Too Hot? Mass Climate Migration & The Rise of Uninhabitable Regions with Sunil Amrith
In the next 25 years, the International Organization for Migration estimates that one billion people will be displaced from their homes due to climate-related events. From island nations underwater to inland areas too hot and extreme to sustain life, the individuals and communities in these areas will need somewhere new to live. Where will these people go, and how will this mass migration add further pressure to the stability of nations and the world? In this episode, Nate is joined by environmental and migration historian, Sunil Amrith, to explore the complex history of human movement – and what it rev...

Key Blindspots of the "Walrus" Movement | Frankly 105
In this week's Frankly, Nate unpacks some key blindspots of "the walrus movement"—a placeholder label that's a gentle nod to those championing bold social and ecological ideals. While mostly well-intentioned, this "movement" can miss the stark limits of our planet's unfolding biophysical reality. What happens when lofty goals sidestep ecological and energetic realities? How might we incorporate these oversights to drive clear, purposeful action towards a (more) sustainable future? And how do we ground ourselves in biophysical truths while envisioning a system that better serves the planet and its people? (Recorded August 11, 2025) ...

How Do You Become Who You Want to Be?: The Science Behind Identity, Purpose, and Motivation with Taylor Guthrie
Our personal concept of identity shapes every decision we make – ranging from life-altering choices to our smallest daily preferences. Identity influences our values, the relationships we build, and how we respond to an increasingly unpredictable world, whether in constructive or destructive ways. But how are these identities formed, and how might we take a more deliberate role in cultivating a healthy sense of self – and therefore a healthier way of relating to the world? In this episode, Nate is joined by social neuroscientist Taylor Guthrie to delve into the neuroscience of identity, exploring how the brain constructs a se...

Ducks and Blueberries: A Reflection on Price, Cost and Value
In this week's Frankly, Nate shares an excerpt from his daily life that mirrors a larger observation on the human predicament. A grocery shopping trip turns into a reflection on value vs cost, and how consumption in our society is driven by the perception of value that's presented to us. What is the difference in value that our minds create between a $5 container of blueberries, and a $1 container? What is the difference between price, cost and value? What things in our lives do we treat as disposable when they are cheap, but treat as treasure when they a...

The Forgotten Skills of Dying and Grieving Well: How Engaging with Loss Can Help Us Live More Fully with Stephen Jenkinson
In Western culture, topics surrounding death and dying are often considered taboo and are generally avoided in everyday conversations. But this reluctance to fully acknowledge and integrate death as a natural part of the human experience has rendered us less able to cope with the end of life and less prepared to show up for ourselves and the people around us as we inevitably navigate loss. But what if a more skillful engagement with death and grief could actually offer us a more mindful approach to living? In this conversation, Nate is joined by Stephen Jenkinson, a...
