Chances are you’re listening to this on an advanced computer that fits in your pocket, but is really just one tentacle tip of a giant, planet-spanning architecture for the gathering and processing of data. A common sentiment among the smartphone-enabled human population is that we not only don’t own our data, but our data owns us — or, at least, the pressure of responsibility to keep providing data to the Internet and its devices (and the wider project of human knowledge construction) implicates...
Aug 19, 2022•1 hr 23 min•Ep 90•Transcript available on Metacast Human beings are distinctly weird. We live for a very long time after we stop reproducing, move completely differently than all of our closest relatives, lack the power of chimpanzees and other primates but completely outdo most other terrestrial mammals in a contest of endurance. If we think about bodies as hypotheses about the stable features of their ancestral environments, what do the features of our unusual physiology say about what humans ARE, where we come from, the details of our origin ...
Aug 03, 2022•53 min•Ep 89•Transcript available on Metacast Ask any martial artist: It’s not just where a person strikes you but your stance that matters. The amplitude and angle of a blow is one thing but how you can absorb and/or deflect it makes the difference. The same is true in any evolutionary system. Most people seem to know “the butterfly effect” where tiny changes lead to large results, but the inverse also works: complex organisms buffer their development against adverse mutations so that tiny changes cannot redirect the growth of limbs and ot...
Jul 18, 2022•1 hr 15 min•Ep 88•Transcript available on Metacast What is life, and where does it come from? These are two of the deepest, most vexing, and persistent questions in science, and their enduring mystery and allure is complicated by the fact that scientists approach them from a myriad of different angles, hard to reconcile. Whatever else one might identify as universal features of all living systems, most scholars would agree life is a physical phenomenon unfolding in time. And yet current physics is notorious for its inadequacy with respect to tim...
Jul 02, 2022•1 hr 22 min•Ep 87•Transcript available on Metacast Math and music share their mystery and magic. Three notes, played together, make a chord whose properties could not be predicted from those of the separate notes. In the West, music theory and mathematics have common origins and a rich history of shaping and informing one another’s field of inquiry. And, curiously, Western composition has evolved over several hundred years in much the same way economies and agents in long-running simulations have: becoming measurably more complex; encoding more ...
Jun 18, 2022•1 hr 25 min•Ep 86•Transcript available on Metacast We lead our lives largely unaware of the immense effort required to support them. All of us grew up inside the so-called “Grid” — actually one of many interconnected regional power grids that electrify our modern world. The physical infrastructure and the regulatory intricacies required to keep the lights on: both have grown organically, piecemeal, in complex networks that nobody seems to fully understand. And yet, we must. Compared to life 150 years ago, we are all utterly dependent on the powe...
Jun 04, 2022•1 hr 8 min•Ep 85•Transcript available on Metacast As our world knits together, economic interdependencies change in both shape and nature. Supply chains, finance, labor, technological innovation, and geography interact in puzzling nonlinear ways. Can we step back far enough and see clearly enough to make sense of these interactions? Can we map the landscape of capability across scales? And what insights emerge by layering networks of people, firms, states, markets, regions? We’re all riding a bucking horse; what questions can we ask to make sur...
May 21, 2022•1 hr 21 min•Ep 84•Transcript available on Metacast In the digital era, data is practically the air we breathe. So why does everybody treat it like a product to be hoarded and sold at profit? How would our world change if Big Tech operated on assumptions and incentives more aligned with the needs of a healthy society? Are more data — or are bigger models — really better? As human beings scamper around like prehistoric mammals under the proverbial feet of the new enormous digital monopolies that have emerged due to the Web’s economies of scale, ho...
May 06, 2022•51 min•Ep 83•Transcript available on Metacast The world is unfair — but how much of that unfairness is inevitable, and how much is just contingency? After centuries of efforts to arrive at formal theories of history, society, and economics, most of us still believe and act on what amounts to myth. Our predecessors can’t be faulted for their lack of data, but in 2022 we have superior resources we’re only starting to appreciate and use. In honor of the Santa Fe Institute’s new role as the hub of an international research network exploring Eme...
Apr 21, 2022•53 min•Ep 82•Transcript available on Metacast Context is king: whether in language, ecology, culture, history, economics, or chemistry. One of the core teachings of complexity science is that nothing exists in isolation — especially when it comes to systems in which learning, memory, or emergent behaviors play a part. Even though this (paradoxically) limits the universality of scientific claims, it also lets us draw analogies between the context-dependency of one phenomenon and others: how protein folding shapes HIV evolution is meaningfull...
Apr 08, 2022•1 hr 14 min•Ep 81•Transcript available on Metacast As fictional Santa Fe Institute chaos mathematician Ian Malcolm famously put it, “Life finds a way” — and this is perhaps nowhere better demonstrated than by roots: seeking out every opportunity, improving in their ability to access and harness nutrients as they’ve evolved over the last 400 million years. Roots also exemplify another maxim for living systems: “What doesn’t kill you makes you stronger.” As the Earth’s climate has transformed, the plants and fungi have transformed along with it, r...
Mar 26, 2022•54 min•Ep 80•Transcript available on Metacast Autonomous vehicles hardly live up to their name. The goal of true “driverlessness” was originally hyped in the 1930s but keeps getting kicked further and further into the future as the true complexity of driving comes into ever-sharper and more daunting focus. In 2022, even the most capable robotic cars aren’t self-determining agents but linked into swarms and acting as the tips of a vast and hidden web of design, programming, legislation, and commercial interest. Infrastructure is more than th...
Mar 11, 2022•57 min•Ep 79•Transcript available on Metacast Irrespective of your values, if you’re listening to this, you live in a pecking order. Dominance hierarchies, as they’re called by animal behaviorists, define the lives of social creatures. The society itself is a kind of individual that gathers information and adapts to its surroundings by encoding stable environmental features in the power relationships between its members. But what works for the society at large often results in violence and inequity for its members; as the founder of this fi...
Feb 25, 2022•1 hr 14 min•Ep 78•Transcript available on Metacast As a careful study of the world, science is reflective and reactive — it constrains our flights of fancy, anchors us in hard-won fact. By contrast, science fiction is a speculative world-building exercise that guides imagination and foresight by marrying the known with the unknown. The field is vast; some sci-fi writers pay less tribute to the line between the possible and the impossible. Others, though, adopt a far more sober tactic and write “hard” sci fi that does its best to stay within the ...
Feb 11, 2022•54 min•Ep 77•Transcript available on Metacast COVID has exposed and possibly amplified the polarization of society. What can we learn from taking a multiscale approach to crisis response? There are latencies in economies of scale, inequality of access and supply chain problems. The virus evolves faster than peer review. Science is politicized. But thinking across scales offers answers, insights, better questions… Welcome to COMPLEXITY , the official podcast of the Santa Fe Institute . I’m your host, Michael Garfield , and every other week w...
Jan 27, 2022•46 min•Ep 76•Transcript available on Metacast Some people say we’re all in the same boat; others say no, but we’re all in the same storm. Wherever you choose to focus the granularity of your inquiry, one thing is certain: we are all embedded in, acting on, and being acted upon by the same nested networks. Our fates are intertwined, but our destinies diverge like weather forecasts, hingeing on small variations in contingency: the circumstances of our birth, the changing contexts of our lives. Seen through a complex systems science lens, the ...
Jan 13, 2022•46 min•Ep 75•Transcript available on Metacast If you’re honest with yourself, you’re likely asking of the last two years: What happened? The COVID-19 pandemic is a prism through which our stories and predictions have refracted…or perhaps it’s a kaleidoscope, through which we can infer relationships and causes, but the pieces all keep shifting. One way to think about humankind’s response to COVID is as a collision between predictive power and understanding, highlighting how far the evolution of our comprehension has trailed behind the evolut...
Dec 22, 2021•1 hr 11 min•Ep 74•Transcript available on Metacast Democracy is a quintessential complex system: citizens’ decisions shape each other’s in nonlinear and often unpredictable ways; the emergent institutions exert top-down regulation on the individuals and orgs that live together in a polity; feedback loops and tipping points abound. And so perhaps it comes as no surprise in our times of turbulence and risk that democratic processes are under extraordinary pressure from the unanticipated influences of digital communications media, rapidly evolving ...
Dec 13, 2021•58 min•Ep 73•Transcript available on Metacast What makes a satisfying explanation? Understanding and prediction are two different goals at odds with one another — think fundamental physics versus artificial neural networks — and even what defines a “simple” explanation varies from one person to another. Held in a kind of ecosystemic balance, these diverse approaches to seeking knowledge keep each other honest…but the use of one kind of knowledge to the exclusion of all others leads to disastrous results. And in the 21st Century, the differe...
Nov 24, 2021•1 hr 21 min•Ep 72•Transcript available on Metacast Where does cultural innovation come from? Histories often simplify the complex, shared work of creation into tales of Great Men and their visionary genius — but ideas have precedents, and moments, and it takes two different kinds of person to have and to hype them. The popularity of “influencers” past and present obscures the collaborative social processes by which ideas are born and spread. What can new tools for the study of historical literature tell us about how languages evolve…and what mig...
Nov 05, 2021•33 min•Ep 71•Transcript available on Metacast When British scientist and novelist C.P. Snow described the sciences and humanities as “two cultures” in 1959, it wasn’t a statement of what could or should be, but a lament over the sorry state of western society’s fractured intellectual life. Over sixty years later the costs of this fragmentation are even more pronounced and dangerous. But advances in computing now make it possible for historians and engineers to speak in one another’s languages, catalyzing novel insights in each other’s home ...
Oct 23, 2021•46 min•Ep 70•Transcript available on Metacast Can you write a novel using only nouns? Well, maybe…but it won’t be very good, nor easy, nor will it tell a story. Verbs link events, allow for narrative, communicate becoming. So why, in telling stories of our economic lives, have people settled into using algebraic theory ill-suited to the task of capturing the fundamentally uncertain, open and evolving processes of innovation and exchange? Welcome to COMPLEXITY , the official podcast of the Santa Fe Institute . I’m your host, Michael Garfield...
Oct 07, 2021•1 hr 3 min•Ep 69•Transcript available on Metacast What is the economy? People used to tell stories about the exchange of goods and services in terms of flows and processes — but over the last few hundred years, economic theory veered toward measuring discrete amounts of objects. Why? The change has less to do with the objective nature of economies and more to do with what tools theorists had available. And scientific instruments — be they material technologies or concepts — don’t just make new things visible, but also hide things in new blind s...
Sep 24, 2021•52 min•Ep 68•Transcript available on Metacast Whether in an ecosystem, an economy, a jazz ensemble, or a lone scholar thinking through a problem, critical transitions — breakdowns and breakthroughs — appear to follow universal patterns. Creative leaps that take place in how mathematicians “think out loud” with body, chalk, and board look much like changes in the movement through “music-space” traced by groups of improvisers. Society itself appears to have an “aha moment” when a meme goes viral or a new word emerges in the popular vocabulary...
Sep 08, 2021•1 hr 4 min•Ep 67•Transcript available on Metacast We are all investors: we all make choices, all the time, about our allocation of time, calories, attention… Even our bodies, our behavior and anatomy, represent investment in specific strategies for navigating an evolving world. And yet most people treat the world of finance as if it is somehow separate from the rest of life — including people who design the tools of finance, or who come up with economic theories. Many of the human world’s problems can be traced back to this fundamental error, a...
Aug 14, 2021•1 hr 6 min•Ep 66•Transcript available on Metacast The popular conception of ants is that “anatomy is destiny”: an ant’s body type determines its role in the colony, for once and ever. But this is not the case; rather than forming rigid castes, ants act like a distributed computer in which tasks are re-allocated as the situation changes. “Division of labor” implies a constant “assembly line” environment, not fluid adaptation to evolving conditions. But ants do not just “graduate” from one task to another as they age; they pivot to accept the wor...
Jul 30, 2021•54 min•Ep 65•Transcript available on Metacast Seventy thousand years ago, humans migrated on foot across the ancient continent of Sahul — the landmass that has since split up into Australia and New Guinea. Mapping the journeys of these ancient voyagers is no small task: previous efforts to understand prehistoric migrations relied on coarse estimates based on genomic studies or on spotty records of recovered artifacts. Now, progress in the fields of geographic information system mapping and agent-based modeling can help archaeologists run ma...
Jul 16, 2021•1 hr 6 min•Ep 64•Transcript available on Metacast This week we conclude our two-part discussion with ecologist Mark Ritchie of Syracuse University on how he and his SFI collaborators are starting to rethink the intersections of thermodynamics and biology to better fit our scientific models to the patterns we observe in nature. Most of what we know about the enzymatic processes of plant and animal metabolisms comes from test tube experiments, not studies in the context of a living organism. What changes when we zoom out and think about life’s ma...
Jul 01, 2021•46 min•Ep 63•Transcript available on Metacast Deep inside your cells, the chemistry of life is hard at work to make the raw materials and channel the energy required for growth, maintenance, and reproduction. Few systems are as intricate or as mysterious. For this reason, how a cell does what it does remains a frontier for research — and, consequently, theory often grows unchecked by solid data. Most of what we know about the enzymatic processes of plant and animal metabolisms comes from test tube experiments, not studies in the context of ...
Jun 17, 2021•41 min•Ep 62•Transcript available on Metacast The 19th Century saw many transformations: the origins of ecology and modern climatology, new unifying theories of the living world, the first Big Science projects, revolutions in the Spanish colonies, new information systems for the storage and representation of data… Many of these can be traced back to the influence of one singular explorer, Alexander von Humboldt. Humboldt was one of the last true polymathic individuals in whom the sum of human knowledge could be seated. As the known world gr...
