Nick Kokonas and Richard Thaler, Nobel Prize Laureate — Realistic Economics, Avoiding The Winner’s Curse, Using Temptation Bundling, and Going Against the Establishment (#830)

Richard H. Thaler (@r_thaler) is the 2017 recipient of the Nobel Memorial Prize in Economic Sciences for his contributions to behavioral economics and the Charles R. Walgreen Distinguished Service Professor of Behavioral Science and Economics at the University of Chicago Booth School of Business. He is also a founding principal at FullerThaler Asset Management, which uses behavioral finance to manage over $30 billion in small-cap US equities. 

Thaler has been a professional disrupter. He helped create the fields of behavioral economics and finance that lie in the gap between economics and psychology. He investigates the implications of relaxing the standard economic assumption that everyone in the economy is rational and selfish, instead entertaining the possibility that some of the agents in the economy are sometimes human. 

Thaler is the New York Times bestselling coauthor of Nudge: Improving Decisions About Health, Wealth, and Happiness (with Cass R. Sunstein) and the author of Misbehaving: The Making of Behavioral Economics. His new book is The Winner’s Curse: Behavioral Economics Anomalies, Then and Now, co-authored with economist Alex O. Imas. 

My co-host is Nick Kokonas (@nickkokonas), an entrepreneur, investor, and author best known as the co-founder of The Alinea Group (sold, 2024) and the reservation platform Tock (now owned by American Express). After revolutionizing how restaurants and experiences are crafted, booked, and managed, he’s now focused on creative ventures that blend business, technology, and art—from immersive theater projects to Napa Valley winemaking. A philosophy graduate of Colgate University, he is as interested in ideas and first principles as he is in building things that last. He lives in Chicago and Napa Valley with his wife and two sons.

“I think a future that’s awesome is absolutely possible. A shitty future is also possible, but the balance is up to us.”

— Pablos Holman

“I tried to do tango first for a month, but it takes advantage of none of my natural talents. You can’t do reverse engineering in tango. It’s too structured and disciplined and minute, and salsa, you can just wiggle your way through it.”

— Pablos Holman

“Most people, if you get a new gadget, like your phone, and give it to your mom, she’ll ask you, ‘What does this do?’ That’s a totally normal question. ‘iPhone, Mom. Says on the box.’ If you give a new gadget to a hacker, then the question is, ‘What can I make this do?'”

— Pablos Holman

“You can’t invent a new technology by reading the directions. That’s just never happened, ever.”

— Pablos Holman

“I had a computer in the cold, in the dark, in the basement, in Alaska, and nobody to show me anything about how it worked. So I had to learn by reverse engineering.”

— Pablos Holman

I do have a kind of extreme risk tolerance. My whole career, I’ve only worked on things that I thought were cool or interesting. I’ll optimize for that over everything else.

— Pablos Holman

“Pablos is a totally fake name because all hackers have fake names.”

— Pablos Holman

Want to hear another episode with someone who asks “What can I make this do?” Listen to my conversation with legendary hacker Samy Kamkar, in which we discussed creating the fastest-spreading computer virus of all time, accidentally taking down MySpace, getting raided by the Secret Service, hijacking drones with custom hardware, optimizing online dating through reverse engineering, opening locked cars, manipulating Google Maps traffic data, and much more.

and APOE4 alleles, associated with moderately increased risk of Alzheimer’s disease compared to APOE3/3 but lower risk than APOE4/4.Type 3 Diabetes: A term used to describe Alzheimer’s disease as a form of insulin resistance and insulin deficiency that occurs specifically in the brain, characterized by impaired neuronal glucose metabolism.The Four Horsemen of Chronic Disease: The four pillars of chronic disease, according to Dr. Peter Attia.Glucose Hypometabolism: A state where the brain’s ability to use glucose for energy is impaired, often occurring more than 10 years before the onset of Alzheimer’s disease symptoms and considered a key feature of neurodegeneration.Neuroinflammation: Inflammation of nervous tissue involving activation of microglia and astrocytes, considered a major driver of neurodegenerative diseases including Alzheimer’s, Parkinson’s, and multiple sclerosis.Ketogenic Diet: A very low-carbohydrate (typically under 50g per day), high-fat diet originally developed at Mayo Clinic in the 1920s to treat epilepsy, which forces the body to produce ketones for fuel instead of using glucose.Mediterranean-Style Low-Carb Diet: A modified version of the traditional Mediterranean diet that reduces carbohydrate intake while emphasizing vegetables, fish, olive oil, nuts, and healthy fats to support weight loss and blood sugar control.Exogenous Ketones: Ketone bodies (primarily beta-hydroxybutyrate) that are consumed through nutritional supplements in the form of ketone salts, esters, or precursor compounds, allowing for rapid elevation of blood ketones without dietary restriction.Ketone Monoester vs. Diester vs. Salts: Different forms of exogenous ketone supplements where monoesters provide the most efficient ketone elevation, diesters are bonds between two ketone molecules, and salts combine ketones with minerals like sodium or potassium.Glucose Ketone Index (GKI): A ratio calculated by dividing blood glucose levels by ketone levels, used as a biomarker for metabolic health and the depth of ketosis, with lower values indicating better metabolic flexibility.Fasting and “Sardine Fasting”: Abstaining from food for therapeutic benefits, with “sardine fasting” referring to a modified fasting approach where only sardines are consumed, providing protein while maintaining some benefits of fasting.Autophagy: The body’s cellular recycling process of cleaning out damaged organelles and proteins to regenerate newer, healthier cellular components, enhanced during periods of fasting and ketosis.Cancer Cachexia: A complex metabolic syndrome characterized by severe loss of muscle mass and body weight, often accompanied by anemia, weakness, and loss of appetite in cancer patients.Metabolic Psychiatry: An emerging field that uses metabolic interventions, particularly ketogenic diets and exogenous ketones, to treat mental health conditions by addressing underlying metabolic dysfunction in the brain.NLRP3 Inflammasome: A multiprotein complex in immune cells that acts as a cellular sensor and triggers inflammatory responses, playing a crucial role in innate immunity and implicated in various neurodegenerative diseases.Metabolic Control of Epigenetic Regulation: The concept that metabolites like beta-hydroxybutyrate can directly influence gene expression by acting as signaling molecules and histone deacetylase inhibitors, affecting cellular function and health.Redox Stress: An imbalance in the cellular ratio of NAD+ to NADH that can impair mitochondrial function and energy production, often associated with aging and metabolic dysfunction.Hyperbaric Oxygen Therapy (HBOT): A medical treatment involving breathing pure oxygen in a pressurized chamber at 1.5 to 3 times normal atmospheric pressure, used to enhance healing and treat various conditions including wound healing and carbon monoxide poisoning.Lipid Energy Model: A metabolic model explaining how LDL cholesterol and ApoB particles can be elevated on low-carbohydrate diets as they function as transport vehicles for mobilized fatty acids used for energy production.SARM (Selective Androgen Receptor Modulator): A class of therapeutic compounds designed to selectively bind to androgen receptors in specific tissues, potentially offering the muscle-building benefits of anabolic steroids with reduced androgenic side effects.Substances & DrugsBeta-Hydroxybutyrate (BHB): The primary ketone body produced during fat metabolism and ketosis, used as an alternative energy source for the brain and body.1,3-Butanediol: A ketone precursor and alcohol compound that is metabolized into beta-hydroxybutyrate (BHB) in the liver.MCT Oil (Medium-Chain Triglyceride): A type of saturated fat that is readily absorbed and converted into ketones, commonly used in ketogenic diets.Creatine Monohydrate: A supplement that helps regenerate ATP in muscles, known for improving exercise performance, strength, and potentially cognitive function.Lipopolysaccharide (LPS): A component of gram-negative bacterial cell walls used in research to induce systemic inflammation and study immune responses.Ezetimibe (Zetia): A prescription medication that lowers cholesterol by inhibiting its absorption in the small intestine.Rapamycin: An immunosuppressive drug originally used to prevent organ rejection that has gained

health.Berberine/Dihydroberberine: Plant-derived alkaloid compounds with glucose-lowering effects similar to metformin, used for metabolic health support.GLP-1 Agonists: A class of diabetes medications that mimic incretin hormones to regulate blood sugar and promote weight loss, including drugs like semaglutide and tirzepatide.SGLT-2 Inhibitors: A class of diabetes medications that lower blood sugar by preventing glucose reabsorption in the kidneys, causing excess glucose to be excreted in urine.NAD Supplements: Supplements like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) designed to boost cellular NAD+ levels for potential anti-aging benefits.Idebenone / CoQ10 / Ubiquinol: Antioxidant compounds that support mitochondrial energy production and cellular health, with CoQ10 being essential for ATP synthesis.GABA / Phenibut: Gamma-aminobutyric acid and related compounds that have calming, inhibitory effects on the central nervous system.Diphenhydramine (Benadryl): An over-the-counter antihistamine commonly used for allergies that causes drowsiness and is sometimes used as a sleep aid.Melatonin: A hormone naturally produced by the pineal gland that regulates the sleep-wake cycle and is commonly used as a sleep supplement.Ostarine: A selective androgen receptor modulator (SARM) that selectively targets muscle and bone

DOMINIC D’AGOSTINO QUOTES FROM THE INTERVIEW

“I think the beauty of ketogenic [therapy] is that it’s pleiotropic, right? Which means it’s many mechanisms working in synergy.”

— Dr. Dominic D’Agostino

“I think the best way to measure to suggest you’re in autophagy is a glucose ketone index after a period of fasting.”

— Dr. Dominic D’Agostino

“About 30 percent of the population hyperabsorbs cholesterol.”

— Dr. Dominic D’Agostino

“HSCRP is a better indicator of cardiovascular disease than LDL cholesterol. We know that now. [No one would believe it] If someone said that 10 years ago.”

— Dr. Dominic D’Agostino

“I wouldn’t go above three, probably 1.5 to 2 millimolar range. That seems to be a level of ketones that safely does not produce a metabolic acidosis.”

— Dr. Dominic D’Agostino

“When we published the NLRP3, I got requests from Genentech and various pharmaceutical companies to go there and give a talk on the mechanism so they could drugify. And I would throw up a big flow chart of all these mechanisms, and I think they would get frustrated. And it was like, ‘Well, tell us the mechanism so we can make a drug out of this.'”

— Dr. Dominic D’Agostino

“I went on a vacation where I forgot melatonin and I slept like a baby probably because I was up every morning. The sun is the ultimate circadian synchronizer. I got off of melatonin to check my endogenous melatonin, and there was no suppression.”

— Dr. Dominic D’Agostino

“So we went to these blue zones and they just, at night after their dinner, the males will do a shot of alcohol, usually wine, but sometimes ouzo and they’re all in their nineties and hundreds, they’re in the blue zone. So it’s a universal characteristic.”

— Dr. Dominic D’Agostino

Want to hear the last time Dom was on the show? Listen to our previous conversation in which we discussed disease prevention, longevity, cancer, ketogenic diet mastery, the detoxifying effects of ketosis on pre-cancerous cells, how to jumpstart daily ketogenic cycles, “cheat” meals, and much more.

What Most Has My Attention Right Now — Credible (vs. Bogus) Vagus Nerve Stimulation (#824)

Kevin J. Tracey, MD (@KevinJTraceyMD), is president and CEO of the Feinstein Institutes for Medical Research at Northwell Health, a pioneer of vagus-nerve research, and author of the recent book The Great Nerve: The New Science of the Vagus Nerve and How to Harness Its Healing Reflexes. 

His contributions include identifying the therapeutic action of monoclonal anti-TNF antibodies and discovering the specific reflex control of immunity by the nervous system, called the “inflammatory reflex.” These discoveries launched the new scientific field called bioelectronic medicine, which investigates the therapeutic applications of vagus-nerve stimulation to cure disease.

Dr. Tracey, a neurosurgeon, pursued studies of inflammation after the mysterious death, from sepsis, of a toddler who was in his care. His lab has since revealed molecular mechanisms of inflammation and identified the use of vagus-nerve stimulation to treat it. An inventor on more than 120 US patents and the author of more than 450 scientific publications, he is among the most highly cited scientists in the world. He co-founded the Global Sepsis Alliance, is the author of Fatal Sequence, and is a national and international lecturer.

KEVIN TRACEY QUOTES FROM THE INTERVIEW

“60 million people die on the planet Earth every year. And 40 million of them die from heart disease, stroke, neurodegeneration, Alzheimer’s, Parkinson’s, metabolic syndrome, diabetes, and cancer. So two thirds of the people that die every year on the planet Earth die of those conditions. And that’s according to the WHO. Those conditions all have one thing in common: they’re either caused by inflammation or made worse by inflammation.”

— Dr. Kevin Tracey

“It was just announced that the company SetPoint Medical, which will now be marketing a device to stimulate the vagus nerve to treat rheumatoid arthritis, has received FDA approval. So there’ll be a product launch underway for everything we’re about to talk about in the context of using a medical device that activates an evolutionarily conserved and ancient reflex through which the brain can suppress inflammation when it’s running out of control.”

— Dr. Kevin Tracey

“We’ve discovered that signals travel from the brain through the vagus nerve. … These signals traveling in the vagus nerve are like the brakes on your car. And when you tap those brakes to slow your car barreling down the hill, this device activates what we call the inflammatory reflex.”

— Dr. Kevin Tracey

“If we can find such nerves, then we can build devices to control the nerves, and the devices become the therapy. The bioelectronic medicine story works as long as you know the molecular mechanism, and that’s where people have to be really careful with vagus-nerve stimulation.”

— Dr. Kevin Tracey

“Almost everybody until a hundred years ago, 150 years ago, almost everybody died by the time they were 30. And what happened in the last 150 years can be summarized in a very simple sentence. The human race in the last 150 years removed infection as the leading cause of death. … I think something similar will happen maybe in the next 20 years if we can really understand how to modify inflammation.”

— Dr. Kevin Tracey

“My adage for this thing is, when you don’t understand a disease, think of epilepsy. You start off, you blame God. So they did exorcisms, and that doesn’t work. So if it’s not God’s fault, the next thing you do is you blame the patient. And when you realize it’s not the patient’s fault, in today’s era, oftentimes we find out it’s actually caused, there’s some infectious cause of this thing. And so autoimmune disease may have an infectious cause, it may have an environmental cause. People talk about genetic causes. You inherit some level of risk for autoimmune diseases, but in very few of these conditions do you actually inherit the condition.”

Dr. Kevin Tracey — Stimulating the Vagus Nerve to Tame Inflammation, Alleviate Depression, Treat Autoimmune Disorders (e.g., Rheumatoid Arthritis), and Much More (#824)

Kevin J. Tracey, MD (@KevinJTraceyMD), is president and CEO of the Feinstein Institutes for Medical Research at Northwell Health, a pioneer of vagus-nerve research, and author of the recent book The Great Nerve: The New Science of the Vagus Nerve and How to Harness Its Healing Reflexes. 

His contributions include identifying the therapeutic action of monoclonal anti-TNF antibodies and discovering the specific reflex control of immunity by the nervous system, called the “inflammatory reflex.” These discoveries launched the new scientific field called bioelectronic medicine, which investigates the therapeutic applications of vagus-nerve stimulation to cure disease.

Dr. Tracey, a neurosurgeon, pursued studies of inflammation after the mysterious death, from sepsis, of a toddler who was in his care. His lab has since revealed molecular mechanisms of inflammation and identified the use of vagus-nerve stimulation to treat it. An inventor on more than 120 US patents and the author of more than 450 scientific publications, he is among the most highly cited scientists in the world. He co-founded the Global Sepsis Alliance, is the author of Fatal Sequence, and is a national and international lecturer.

KEVIN TRACEY QUOTES FROM THE INTERVIEW

“60 million people die on the planet Earth every year. And 40 million of them die from heart disease, stroke, neurodegeneration, Alzheimer’s, Parkinson’s, metabolic syndrome, diabetes, and cancer. So two thirds of the people that die every year on the planet Earth die of those conditions. And that’s according to the WHO. Those conditions all have one thing in common: they’re either caused by inflammation or made worse by inflammation.”

— Dr. Kevin Tracey

“It was just announced that the company SetPoint Medical, which will now be marketing a device to stimulate the vagus nerve to treat rheumatoid arthritis, has received FDA approval. So there’ll be a product launch underway for everything we’re about to talk about in the context of using a medical device that activates an evolutionarily conserved and ancient reflex through which the brain can suppress inflammation when it’s running out of control.”

— Dr. Kevin Tracey

“We’ve discovered that signals travel from the brain through the vagus nerve. … These signals traveling in the vagus nerve are like the brakes on your car. And when you tap those brakes to slow your car barreling down the hill, this device activates what we call the inflammatory reflex.”

— Dr. Kevin Tracey

“If we can find such nerves, then we can build devices to control the nerves, and the devices become the therapy. The bioelectronic medicine story works as long as you know the molecular mechanism, and that’s where people have to be really careful with vagus-nerve stimulation.”

— Dr. Kevin Tracey

“Almost everybody until a hundred years ago, 150 years ago, almost everybody died by the time they were 30. And what happened in the last 150 years can be summarized in a very simple sentence. The human race in the last 150 years removed infection as the leading cause of death. … I think something similar will happen maybe in the next 20 years if we can really understand how to modify inflammation.”

— Dr. Kevin Tracey

“My adage for this thing is, when you don’t understand a disease, think of epilepsy. You start off, you blame God. So they did exorcisms, and that doesn’t work. So if it’s not God’s fault, the next thing you do is you blame the patient. And when you realize it’s not the patient’s fault, in today’s era, oftentimes we find out it’s actually caused, there’s some infectious cause of this thing. And so autoimmune disease may have an infectious cause, it may have an environmental cause. People talk about genetic causes. You inherit some level of risk for autoimmune diseases, but in very few of these conditions do you actually inherit the condition.”

#824: Dr. Kevin Tracey — Stimulating The Vagus Nerve to Tame Inflammation, Alleviate Depression, Treat Autoimmune Disorders (e.g., Rheumatoid Arthritis), and Much More (#824)

Kevin J. Tracey, MD (@KevinJTraceyMD), is president and CEO of the Feinstein Institutes for Medical Research at Northwell Health, a pioneer of vagus nerve research and author of the recent book, The Great Nerve: The New Science of the Vagus Nerve and How to Harness Its Healing Reflexes. 

His contributions include identifying the therapeutic action of monoclonal anti-TNF antibodies and discovering the specific reflex control of immunity by the nervous system, called the “inflammatory reflex.” These discoveries launched the new scientific field called bioelectronic medicine, which investigates the therapeutic applications of vagus nerve stimulation to cure disease.

Dr. Tracey, a neurosurgeon, pursued studies of inflammation after the mysterious death, from sepsis, of a toddler who was in his care. His lab has since revealed molecular mechanisms of inflammation and identified the use of vagus nerve stimulation to treat it. An inventor on more than 120 US patents and the author of more than 450 scientific publications, he is among the most highly cited scientists in the world. He co-founded the Global Sepsis Alliance, is the author of Fatal Sequence, and is a national and international lecturer.

KEVIN TRACEY QUOTES FROM THE INTERVIEW

“60 million people die on the planet Earth every year. And 40 million of them die from heart disease, stroke, neurodegeneration, Alzheimer’s, Parkinson’s, metabolic syndrome, diabetes, and cancer. So two thirds of the people that die every year on the planet Earth die of those conditions. And that’s according to the WHO. Those conditions all have one thing in common — they’re either caused by inflammation or made worse by inflammation.”

— Dr. Kevin Tracey

“It was just announced that the company SetPoint Medical, which will now be marketing a device to stimulate the vagus nerve to treat rheumatoid arthritis, has received FDA approval. So there’ll be a product launch underway for everything we’re about to talk about in the context of using a medical device that activates an evolutionarily conserved and ancient reflex through which the brain can suppress inflammation when it’s running out of control.”

— Dr. Kevin Tracey

“We’ve discovered that signals travel from the brain through the vagus nerve. … These signals traveling in the vagus nerve are like the brakes on your car. And when you tap those brakes to slow your car barreling down the hill, this device activates what we call the inflammatory reflex.”

— Dr. Kevin Tracey

“If we can find such nerves, then we can build devices to control the nerves, and the devices become the therapy. The bioelectronic medicine story works as long as you know the molecular mechanism, and that’s where people have to be really careful with vagus nerve stimulation.”

— Dr. Kevin Tracey

“Almost everybody until a hundred years ago, 150 years ago, almost everybody died by the time they were 30. And what happened in the last 150 years can be summarized in a very simple sentence. The human race in the last 150 years removed infection as the leading cause of death. … I think something similar will happen maybe in the next 20 years if we can really understand how to modify inflammation.”

— Dr. Kevin Tracey

“My adage for this thing is, when you don’t understand a disease, think of epilepsy. You start off, you blame God. So they did exorcisms, and that doesn’t work. So if it’s not God’s fault, the next thing you do is you blame the patient. And when you realize it’s not the patient’s fault, in today’s era, oftentimes we find out it’s actually caused, there’s some infectious cause of this thing. And so autoimmune disease may have an infectious cause, it may have an environmental cause. People talk about genetic causes. You inherit some level of risk for autoimmune diseases, but in very few of these conditions do you actually inherit the condition.”

Want to hear another episode about the future of electroceuticals and brain stimulation? Listen to my conversation with Stanford’s Dr. Nolan Williams, in which we discussed 70%–90% remission rates for treatment-resistant depression, brain stimulation for sports performance, accelerated TMS protocols, de-risking ibogaine for TBI/PTSD, the future of “electroceuticals,” and much more.

The post #824: Dr. Kevin Tracey — Stimulating The Vagus Nerve to Tame Inflammation, Alleviate Depression, Treat Autoimmune Disorders (e.g., Rheumatoid Arthritis), and Much More (#824) appeared first on The Blog of Author Tim Ferriss.
