We like to believe that we navigate our lives as fully conscious, rational architects of our own destinies. But how much of the life you are living right now is a result of deliberate, conscious choice—and how much is dictated by unseen cognitive shortcuts, subtle societal defaults, and hidden behavioral biases?

In this episode of Journey Through Nature and Science, host Donald Murphy sits down with renowned behavioral economist and best-selling author Dan Ariely for a profound conversation at the intersection of psychology, choice, and human awareness.

Together, they explore the boundary between automatic habit and intentional living. From the subtle forces that steer our decision-making to the deep alignment required to live a truly conscious life, this discussion challenges us to pause, look beneath the surface of our daily routines, and ask: Are we truly conscious of the life we should live?

Key Topics Covered

• The Illusion of Rational Control: Why human beings consistently act against their own best intentions—and why intellect alone doesn't guarantee conscious choices.
• The Architecture of Choice: How small, unexamined environmental cues shape our major life decisions without our awareness.
• Bridging Behavioral Science & Consciousness: Merging the empirical study of human irrationality with the deeper search for personal meaning and alignment.
• Awakening to Intentionality: Practical insights for stepping out of automatic default patterns and reclaiming agency over your path.

"An archival 2023 interview with Anthropic co-founder Jared Kaplan discussing scaling laws, large language models, and the trajectory of artificial intelligence."

"What is the universe? What is intelligence? What is the mind?"

When theoretical physicist turned AI researcher Jared Kaplan shifted his focus to artificial intelligence, he wasn't just looking to build software—he was trying to answer fundamental questions about reality, perception, and thought itself.

In this episode, we’re revisiting a 2023 conversation with Jared, co-founder of Anthropic, recorded just as he was joining the company.

At the time, we sat down to discuss the physics of intelligence, scaling laws, large language models (LLMs), and where machine intelligence was heading. Looking back three years later, with tools like Claude and ChatGPT transforming the global landscape, listening to this snapshot offers an incredible look at how fast the field has evolved—and how much of today's reality was already taking shape in those early research models.

We begin with Jared sharing the story of what first drew him from physics into the world of AI, driven by the ultimate quest to understand how mind and universe intersect.

In This Episode, We Cover:

• From Theoretical Physics to AI: How foundational questions about the universe and human cognition led Jared from fundamental physics to machine intelligence.
• The Physics of Scaling Laws: Understanding the empirical patterns that predict how language models improve as computing power, data, and parameters expand.
• Large Language Models & Emergent Abilities: Early insights into how LLMs acquire complex reasoning behaviors.
• The Trajectory of AI Safety & Alignment: Why Anthropic was formed and the core challenges of building safe, cooperative frontier models.

Is The Earth Losing Its Balance and beginning to turn against us?

Author Dominic Nessi explores that terrifying possibility in The Source, a gripping new science thriller that combines geophysics, political suspense and human survival in a story where Earth’s very stability begins to unravel.

The first installment in a planned trilogy, The Source follows a team of brilliant women scientists racing to understand a growing series of magnetic disturbances, seismic irregularities and atmospheric anomalies that suggest the planet’s rotational balance may be shifting — with potentially catastrophic consequences for civilization.

At the center of the story is Christina Whiting, a NASA geospace specialist whose discoveries challenge humanity’s understanding of the world beneath its feet. As governments react with denial, fear and escalating desperation, the race for answers becomes a global struggle defined as much by politics and survival as by science itself.

The Source

“The Source is ultimately about people,” Nessi says. “It’s about how ordinary individuals respond when systems fail, certainty disappears, and science collides with fear. I wanted the story to feel intellectually grounded, emotionally personal and frighteningly plausible.”

Drawing inspiration from real scientific theories, archaeological mysteries and modern geopolitical tensions, The Source has been described by early readers as “Michael Crichton meets Hidden Figures,” combining large-scale disaster storytelling with a distinctly modern, female-centered perspective.

The book is expected to resonate strongly with readers of speculative thrillers, science-driven fiction, and book club audiences looking for stories that blend suspense with deeper philosophical questions about humanity’s future.

Welcome to my third memoir about my unusual trajectory in the world of medicine. In my first memoir, “Medicine and Miracles in the High Desert,” I shared with readers my profoundly life-changing and eye-opening time on the Navajo Reservation as a young schoolteacher in the early 1970s. Many years later, I returned to the Navajo people to serve them as a medical doctor in Cuba, New Mexico. The second memoir, “From Mountains to Medicine,” takes the reader on a spellbinding, ten-year odyssey in search of my life’s purpose.

This memoir begins with my wide-eyed excitement upon entering medical school. I had an unquenchable eagerness to learn information and skills that would help others. I held no pre-conceived ideas about the kind of education I would receive. Gradually, as time passed, I began suspecting that something wasn’t right about some of the information that the professors and mentors taught the medical students. Long after I completed my training, I discovered why some of the information I learned didn’t make sense, and the conflicts of interest involved in many of the studies that were done that influenced what the medical students were taught.

Scientific research at Yellowstone and other National Park has yielded many useful discoveries benefiting humanity.  One of the most important was the discovery of the thermophilic bacterium, Thermus aquaticus.  Later an enzyme was purified by a team led by Dr. Henry Erlich, which led to the practical use of the PCR test in covid detection and many other uses.

Science in parks is a crucial tool for the advancement of humanity.

However, if it were not for the early efforts of George Menendez Wright, science may have never taken hold in our national parks.  Today, the George Wright Society continues that effort by supporting parks, protected/conserved areas, cultural sites, and other kinds of place-based conservation by encouraging communication among and convenings of researchers, managers, educators, practitioners, and the public to facilitate informed decisions and actions that embrace our values.

Joining me to talk science in our national parks is Dave Harmon, executive director of the George Wright Society.  Dave is responsible for overseeing the George Wright Society’s operations, including co-editing Parks Stewardship Forum and helping plan workshops and other meetings. A member of the GWS since 1985, Dave began working for the organization in 1990 and served as executive director from 1998 to 2017 before returning that role in 2019. He is active in IUCN's World Commission on Protected Areas.  He also maintains a research interest in the relationship between biological and cultural diversity, having co-founded the NGO Terralingua, which is devoted to that subject. Dave has co-edited several volumes on protected area conservation, including The Antiquities Act: A Century of American Archaeology, Historic Preservation, and Nature Conservation (with Francis P. McManamon and Dwight T. Pitcaithley), The Full Value of Parks: From Economics to the Intangible (with Allen D. Putney), and A Thinking Person's Guide to America's National Parks (with Robert Manning, Rolf Diamant, and Nora Mitchell).

On this episode we speak with Dr. Jonathan Zehr.  He and his colleagues discovered an example of evolution in action.  Dr. Zehr will share with us how such a revolutionary discovery was made.

Jonathan Zehr is the distinguished professor at the University of California, Santa Cruz, Institute of Marine Sciences.  He and his colleagues have discovered the possibility of a complex cellular organism with a nitrogen-fixing organelle derived from endosymbiosis with a nitrogen fixing bacteria. This new organelle is called a nitroplast. Studying a marine alga with a cyanobacterial endosymbiont, Zehr and his colleagues  used soft x-ray tomography to visualize cell structure and division of the alga, revealing a coordinated cell cycle in which the endosymbiont divides and is split evenly, similar to the situation for plastids and mitochondria in these cells.  In other words instead of having a symbiotic relationship, the alga and bacteria integrated to form a newly evolved organism.  Dr. Zehr, welcome to the program.  We can’t wait to hear more about this revolutionary discovery.

Moral bankruptcy threatens to destroy national parks under the guise of government efficiency. 

The firing of many national park service employees is illegal.  Why illegal?  Not because some codified law is being violated, rather because a higher moral law is violated.  That law is rooted in the human responsibility of stewardship.   The care and love for our natural and cultural resources seeks to resolve what E.O. Wilson called the great paradox.  That is the natural proclivity of human beings to expand and develop while at the same time conserving and protecting the resources needed for development and expansion. This is the great challenge of stewardship and our National Parks represent humanity’s attempt to resolve this paradox.

When we speak of the benefits of parks it is in these terms that we must speak.  It is dangerous to define the importance of parks and conservation only in terms of the monetary economic benefit.  We must not simply try and make the value of parks and conservation fit within the context of a market economy.   We must understand that the benefits of parks and conservation are more than a commodity in the marketplace, rather they are an important part of the creative processes of the universe.

Franklin Roosevelt noted that:

“There is nothing so American as our national parks. The scenery and the wildlife are native. The fundamental idea behind the parks is native. It is, in brief, that the country belongs to the people, that it is in process of making for the enrichment of the lives of all of us. The parks stand as the outward symbol of the great human principle.

This episode gives an in depth argument for why we have a moral responsibility to protect our national parks.

With competing ideas of how to interpret the meaning of quantum mechanics, physics is in crisis. Can an ancient concept known as the One, rescue physics. From Bohr's Copenhagen interpretation to the Many Worlds theory put forward by Hugh Everett, to the seemingly intractable problem of quantum gravity the challenges facing physics threaten to tear down the very foundation of the science.

In an attempt to save physics from itself, Heinrich Päs has written a compelling book, The One, that offers a solution rooted in the concept that everything we see in the universe, including ourselves, emerges from the One and surprisingly the One itself is made up of everything that we see. How is this possible? Päs proposes that quantum mechanics can show us the way to the answer once we accept that the universe is one.

The revolution in science that is transforming our understanding of extinct life may also lead to Unravelling The Secret Of Life With Ancient Biomolecules.

We used to think of fossils as being composed of nothing but rock and minerals, all molecular traces of life having vanished long ago. We were wrong. Remnants of Ancient Life reveals how the new science of ancient biomolecules—pigments, proteins, and DNA that once functioned in living organisms tens of millions of years ago—is opening a new window onto the evolution of life on Earth.

Paleobiologists are now uncovering these ancient remnants in the fossil record with increasing frequency, shedding vital new light on long-extinct creatures and the lost world they inhabited. Dale Greenwalt is your guide to these astonishing breakthroughs. He explains how ancient biomolecules hold the secrets to how mammoths dealt with the bitter cold, what colors dinosaurs exhibited in mating displays, how ancient viruses evolved to become more dangerous, and much more. Each chapter discusses different types of biomolecules and the insights they provide about the physiology, behavior, and evolution of extinct organisms, many of which existed long before the age of dinosaurs.

A marvelous adventure of discovery, Remnants of Ancient Life offers an unparalleled look at an emerging science that is transforming our picture of the remote past. You will never think of fossils in the same way again. Join us on this episode of Life Is A Story We Tell Ourselves and learn how fossils of all kinds man lead to Unravelling The Secret Of Life With Ancient Biomolecules. You will hear from the first human being ever to see the fossil of a blood-engorged mosquito. This is real-life Jurassic Park.

California was on the world stage recently helping to save the earth's biodiversity at the international biodiversity summit in Montreal, Canada. The countries agreed to protect 30% of the earth's biodiversity by the year 2030. Leading the United States is the state of California, which has put forward an ambition plan called, Pathways to 30x30.

California Governor Newsom’s Executive Order N-82-20 establishes a goal of conserving 30% of California’s lands and coastal waters by 2030. The Governor tasked the California Natural Resources Agency (CRNA) to coordinate the implementation of 30x30 with other State agencies and stakeholders through a series of actions including the development of a framework document, called Pathways to 30x30. The final Pathways to 30x30 strategy document was released in April 2022 and identifies challenges, opportunities, and strategies to achieve 30x30. Pathways to 30x30: Accelerating Conservation of California's Nature will set us on the path to successful implementation through shared action.

Leading this effort is this episode's guest, the secretary of the Resources Agency, Wade Crowfoot. 

Secretary Crowfoot oversees an agency of 21,000 employees who protect and manage California’s natural environment. This includes stewarding the state’s forests and natural lands, rivers and waterways, and coast and ocean, protecting fish and wildlife, and overseeing energy development. As a member of the Governor’s cabinet, he advises Governor Newsom on natural resources and environmental issues.

Secretary Crowfoot firmly believes that good natural resources management helps natural places thrive and allows communities and our economy to prosper. His key priorities include: Building California’s resilience to climate change-driven threats, including wildfire, drought, extreme heat, flooding and sea-level rise. 

Expanding equitable access to parks, natural places and outdoor recreation for all Californians. 
Preserving California’s world-renowned biodiversity of plants and animals.

This past week Secretary Crowfoot attend the international summit on biodiversity in Montreal, Canada where he communicated that California is on the world stage saving the earth's biodiversity.
