Talking “Conversational Doorknobs” & Broken Science with the Funniest Man in Psychology, Adam Mastroianni

Why Your Brain Functions Like a Specialized Swiss Army Knife

Analyze neuroeconomics and leadership with Professor Michael Platt from UPenn on NeuralCompass by JiminiHealth. Professor Platt joins host Mark Jacobstein to discuss the intersection of anthropology, psychology, and neuroscience. The conversation explores how the human brain functions like a Swiss Army knife evolved for an ancestral world. They examine the biological cost of video calls and the critical importance of eye contact for neural synchronization. The discussion also covers the innovation network and the reason disengaging from routine through walking meetings is vital for creativity. Professor Platt shares data from his research on Cayo Santiago showing how social bonds increase survival in the face of catastrophic stress. Finally, the guests address the loneliness epidemic and how to foster resilience in a world dominated by digital glass. What You’ll Learn: * How the social brain network hoovering up data impacts team trust. * The reason physical activity is the top predictor for brain vitality. * How to balance the task network with the default mode network for innovation. * The impact of digital glass on adolescent mental health and global fertility. * How monkey research reveals the biological price of environmental trauma. * Why are the most effective leadership tools, like eye contact, virtually cost-free? About the Guest: Michael Platt is a James Riepe University Professor at UPenn with appointments in the School of Medicine, the School of Arts and Sciences, and Wharton. He is a pioneer in the field of neuroeconomics and the author of The Leader's Brain. His research explores the biological mechanisms of decision making and social interaction in both humans and nonhuman primates. Episode Highlights [00:06:00] The Brain as a Swiss Army Knife: Professor Michael Platt explains that the human brain is a collection of specialized tools evolved for ancient survival. These tools are often mismatched with the current technological environment, where dopamine machines reside in every pocket. Understanding this structural mismatch helps leaders recognize why modern workers face constant information overload. This evolutionary heritage is a foundation for understanding modern psychological despair. [00:13:00] The Social Brain and Video Call Fatigue: Digital communication disrupts the natural social brain network, which relies on constant contextual data like gaze direction and pupil size. When eye contact is broken by cameras and screens, the brain must expend significant energy to read social cues. This increased computational work leads to the exhaustion many experience after a day of virtual meetings. These insights prompted host Mark Jacobstein to modify his own camera setup to improve neural synchronization.  [00:22:51] Walking Meetings and Innovation: Physical activity is the primary factor for maintaining brain vitality and ongoing health. Walking meetings allow the brain to disengage from routine while simultaneously fostering social connection and aerobic movement. This shift in state activates the innovation network, which is otherwise suppressed by focus-heavy tasks. Leaders can use this tool to increase the likelihood of breakthrough ideas within their teams. [00:24:26] Task Network vs Default Mode Network: Creativity is governed by a balance between the central executive network and the default mode network. The task network fires during routine activities like spreadsheets and shuts down the regions responsible for outside-the-box thinking. To generate novel ideas, individuals must explicitly step away from their desks to allow the innovation network to fire. This neurobiological understanding explains why highly creative individuals often struggle with clerical tasks. [00:41:01] Resilience Lessons from Monkey Island: Long-term research on rhesus macaques in Puerto Rico shows how catastrophic stress can accelerate biological aging. After Hurricane Maria, monkeys without strong social ties aged the equivalent of eight human years in a single calendar year. Monkeys that prioritized prosocial behavior and friendship demonstrated a much higher probability of survival. This research indicates that social capital acts as a biological buffer against environmental trauma. [00:33:32] The Crisis of Digital Isolation: The modern loneliness epidemic is a primary driver of plummeting global fertility rates and rising psychological despair. Because interactions are increasingly mediated by screens, people are spending less time crossing paths in the physical world. Reclaiming free-range social experimentation for children is essential for building long-term emotional resilience. The field is actively searching for systemic guardrails like phone-free schools to mitigate these challenges.

Why Healthcare, Ever the Tech Laggard, Finally Got the AI Memo, with Jacob Effron

What if healthcare’s biggest AI breakthroughs aren’t about new science—but about finally fixing systems that were never built to scale? In this episode of Neural Compass, Jacob Effron, Managing Director at Redpoint Ventures, joins Jimini’s Mark Jacobstein to explore where AI is already delivering real value in healthcare—and where hype still outpaces reality. Drawing on his experience at Flatiron Health and as an investor across AI, enterprise software, and healthcare, Jacob discusses why healthcare has become one of the fastest-adopting AI verticals, how real-world data actually creates value, and why tools that reduce clinician burden can unlock entirely new patient experiences. They cover: * Why healthcare has emerged as a leading AI adoption vertical * Lessons from Flatiron Health on real-world data and evidence * What makes ambient clinical documentation a true “wedge” product * How AI can empower patients—not just clinicians * What separates generational health tech companies from short-lived hype Learn more: jiminihealth.com [http://jiminihealth.com]

Talking “Conversational Doorknobs” & Broken Science with the Funniest Man in Psychology, Adam Mastroianni

What if the hardest problems in psychology aren’t about data or statistics—but about how we talk, think, and decide what counts as truth? In this episode of Neural Compass, psychologist, writer, and internet favorite Adam Mastroianni joins Jimini’s Mark Jacobstein for a wide-ranging conversation about conversation itself. Drawing from experimental psychology, improv, and lived experience with anxiety and depression, Adam explores why good conversations feel rare, why science struggles to study the most important questions, and why mental health progress may require ideas that don’t fit into academic boxes. Along the way, he reflects on leaving academia, rethinking peer review, and what happens when you try to tell the truth instead of writing for journals. They cover: * Why great conversations rely on “doorknobs,” not just questions * How anxiety, status, and speed shape the way we talk to each other * What’s broken in modern science—and why legibility can be the enemy of discovery * Why therapy works even when we don’t fully understand how * How imagining that “things could be better” fuels both progress and dissatisfaction Learn more: jiminihealth.com [http://jiminihealth.com]

Tech, AI, and the Future of Therapy, with Dr. Harry Ritter, Alma's CEO

What if fixing mental healthcare isn’t about replacing clinicians—but finally giving them the systems they’ve always lacked? In this episode of Neural Compass, Dr. Harry Ritter, founder and CEO of Alma, joins Jimini’s Mark Jacobstein to explore how technology, insurance alignment, and new business models can unlock better mental health care at scale. Drawing on his experience as a physician, lawyer, and former Oscar Health executive, Harry explains why behavioral health has lagged in tech adoption, how the pandemic permanently reshaped care delivery, and why empowering independent clinicians may be the fastest path to access, quality, and sustainability. They cover: - Why behavioral health remained tech-averse for so long—and what changed - How Alma helps thousands of independent therapists accept insurance and scale - The hidden systems failures between payers, providers, and patients - Where AI can remove administrative burden without replacing clinicians - Why mental health may be the most powerful lever for preventive care Learn more: jiminihealth.com [http://jiminihealth.com]

Can Stress Rewire the Brain—Across a Lifetime? with Dr. Nikolaos Daskalakis

Why do some people emerge from trauma resilient, while others carry its effects for decades—or even generations? In this episode of Neural Compass, Harvard neuroscientist and psychiatrist Dr. Nikos Daskalakis joins Jimini’s Mark Jacobstein to unpack the biology of stress and PTSD. Drawing on decades of research spanning animal models, post-mortem human brain studies, and cutting-edge multi-omics, Dr. Daskalakis explains how genetics, early life stress, and later trauma interact to shape vulnerability, resilience, and mental health outcomes. The conversation explores how glucocorticoid signaling, immune–brain communication, and cell-type-specific transcriptional changes complicate our understanding of PTSD—and why simple, one-size-fits-all treatments continue to fall short. They cover: * The “three-hit” model of stress: genetics, early life experience, and adult trauma * Why cortisol and glucocorticoid signaling matter—but aren’t the whole story * What single-cell and multi-omic brain studies reveal about PTSD versus depression * The unresolved question of whether trauma can be biologically transmitted across generations Learn more: jiminihealth.com [http://jiminihealth.com]
