Top 17 'Worldview-Shattering' University Lectures to watch for Upgrading Your Mental Models This Year - Goh Ling Yong
Ever feel like your brain is running on old software? You navigate your day-to-day life with a set of assumptions and beliefs—your mental models—that you picked up years ago. But the world is constantly changing, and what worked yesterday might be holding you back today. The most effective way to upgrade your thinking isn't just to learn new facts, but to install entirely new operating systems for your mind.
The good news? You don't need a university-sized student loan to do it. Thanks to the magic of the internet, some of the most profound, challenging, and 'worldview-shattering' lectures from the world's greatest minds are available for free. These aren't just dry academic talks; they are intellectual dynamite, designed to blast away outdated assumptions and help you build a more robust, nuanced, and powerful understanding of the world.
As Goh Ling Yong often emphasizes, investing in your mental models is the highest-leverage activity you can undertake for personal and professional growth. This curated list features 17 lectures and series that will do just that. They will challenge your sense of morality, your understanding of reality, and your very concept of self. Get ready to press 'update' on your brain.
1. Michael Sandel’s “Justice” – Questioning Your Moral Compass
Professor Michael Sandel’s legendary Harvard course on moral and political philosophy is the perfect starting point. He doesn't just lecture; he masterfully guides you through complex ethical dilemmas, from runaway trolleys to price gouging after a hurricane, forcing you to confront your own moral reasoning and its inconsistencies.
This series is worldview-shattering because it reveals that the principles we consider "obvious" (like maximizing happiness or respecting individual rights) often clash in profound ways. Sandel unpacks the philosophies of thinkers like Aristotle, Kant, and Mill, not as historical artifacts, but as living tools for navigating the ethical minefields of modern life.
Pro-Tip: Watch this with a friend or partner. After each episode, pause and debate the central question. You'll be amazed at how two reasonable people can arrive at wildly different conclusions, which is precisely the point.
2. Robert Sapolsky’s “Human Behavioral Biology” – Deconstructing Human Nature
Have you ever wondered why people do the things they do? Stanford neurobiologist Robert Sapolsky provides the most comprehensive answer you'll ever find. This lecture series is a tour-de-force, explaining behavior by looking at what happened one second before, minutes before, days before, and even centuries before the action took place.
Sapolsky masterfully connects genetics, hormones, brain structure, evolution, and culture to explain everything from love and aggression to religion and free will. The course fundamentally challenges the simplistic notion that we are entirely free agents, revealing the powerful biological and environmental forces that shape our choices. It doesn't absolve us of responsibility, but it fosters a deep sense of compassion and understanding for human behavior.
Key Takeaway: The next time you judge someone's actions, try applying Sapolsky’s multi-layered framework. You’ll move from simple judgment to a more complex and empathetic understanding.
3. Shelly Kagan’s “Death” – A Rational Look at Mortality
This Yale philosophy course is not about spirituality or the afterlife; it's a rigorously logical and unsentimental examination of mortality. Professor Shelly Kagan, perched casually on his desk, tackles the biggest questions: Is there a soul? Is death bad for us? Would immortality be desirable?
What makes this series so transformative is its directness. Kagan forces you to confront the one certainty in life without the comfort of easy answers. By stripping away dogma, he empowers you to build your own reasoned philosophy about life and its end. You’ll walk away not with fear, but with a profound appreciation for the finite, precious nature of your existence.
4. Leonard Susskind’s “The Theoretical Minimum” – Grasping the Fabric of Reality
If you've ever felt that the true nature of reality—quantum mechanics, relativity, black holes—is beyond your grasp, this series is for you. Stanford physicist Leonard Susskind designed these lectures for people who know some math but aren't physicists, providing the "theoretical minimum" needed to understand modern physics.
Susskind’s lectures will permanently alter how you perceive the universe. The familiar, solid world of classical intuition dissolves into a bizarre and beautiful reality of probabilities, warped spacetime, and quantum entanglement. It’s a challenging series, but the reward is a fundamental upgrade to your model of reality itself.
5. Jordan Peterson’s “Maps of Meaning” – The Psychology of Belief
Before he became a global media figure, Dr. Jordan Peterson was a Harvard and University of Toronto professor whose “Maps of Meaning” lectures explored the psychology behind myth, religion, and ideology. This series is a deep dive into how humans create meaning in a world of chaos and suffering.
Regardless of your personal beliefs, this course is a powerful tool for understanding why we build belief systems and how those narratives—from ancient myths to modern political ideologies—drive our behavior. It shatters the idea that our beliefs are purely rational, revealing the ancient psychological structures that underpin them.
6. Daniel Kahneman’s “Thinking, Fast and Slow” – Hacking Your Own Mind
While not a full university course, Nobel laureate Daniel Kahneman’s lectures summarizing his groundbreaking book are essential viewing. He introduces the mental model of "System 1" (fast, intuitive, emotional thinking) and "System 2" (slow, deliberate, logical thinking) and reveals how our reliance on System 1 leads to predictable cognitive biases.
This knowledge is a superpower. Once you understand the common bugs in human cognition—like confirmation bias, the availability heuristic, and loss aversion—you start seeing them everywhere, especially in yourself. It’s the ultimate guide to debugging your own decision-making process, leading to better choices in your finances, career, and relationships.
7. Richard Feynman’s “The Character of Physical Law” – Finding the Beauty in Science
Recorded at Cornell in 1964, these lectures by Nobel laureate Richard Feynman are timeless. Feynman possessed a rare genius for making the most complex ideas in physics feel intuitive and beautiful. He doesn’t just present facts; he takes you on a journey of scientific discovery, revealing the process of doubt, uncertainty, and wonder.
The worldview shift here is one of perspective. Feynman teaches you to see the world not as a collection of objects, but as a dynamic dance of universal laws. His infectious curiosity is a powerful reminder that the most profound truths are often found by embracing uncertainty and asking simple, child-like questions.
8. Ray Dalio’s “Principles for Success” – An Operating System for Life
Billionaire investor Ray Dalio distilled his life’s lessons into a set of "Principles," which he shares in this engaging animated series. It's essentially a university course on practical wisdom, covering everything from radical open-mindedness to the mechanics of evolution.
Dalio provides a systematic, machine-like framework for achieving goals and learning from failure. His core idea of viewing reality as it is, not as you wish it were, and then dealing with it effectively, is a powerful mental model for anyone looking to improve their results in any area of life.
9. Bret Victor’s “Inventing on Principle” – Aligning Your Work with Your Values
This talk is a must-watch for anyone who creates things—programmers, designers, artists, entrepreneurs. Victor argues that every creator should have a guiding principle, a "north star" that drives their work. He demonstrates his own principle: "Creators need an immediate connection to what they're creating."
The lecture is worldview-shattering because it challenges the notion of working reactively or just "doing the next thing." It's a call to action to find your own core principle and rebuild your creative process around it. It will change not just how you work, but why you work.
10. Yuval Noah Harari’s “Sapiens” – Rewriting Human History
In lectures summarizing his international bestseller, Harari presents a breathtakingly original history of our species. He argues that the secret to Homo Sapiens' success is our unique ability to cooperate flexibly in large numbers by believing in shared fictions—myths, religions, nations, money, and corporations.
This framework completely reframes your understanding of society. You begin to see the world as a multi-layered reality, where physical objects are overlaid with powerful, collectively imagined stories. It’s a profound shift that helps you deconstruct the institutions and beliefs that govern our lives.
11. Hans Rosling’s “The Best Stats You’ve Ever Seen” – Curing Your Cognitive Biases
In this legendary TED Talk, which has the rigor and impact of a full lecture, physician and statistician Hans Rosling uses ingenious data visualization to dismantle our pessimistic and outdated views of the "developing world." He shows, with undeniable data, that the world is in a much better and more hopeful state than most of us believe.
This talk is a direct antidote to the negativity bias amplified by the 24-hour news cycle. It equips you with a data-driven mental model for understanding global trends, shattering the simplistic "us vs. them" narrative and replacing it with a more nuanced and optimistic view of human progress.
12. Paul Bloom’s “Introduction to Psychology” – The User’s Guide to the Brain
This engaging introductory course from Yale is one of the best overviews of psychology you can find. Professor Paul Bloom covers a vast range of topics, from Freud's psychosexual theories to the neuroscience of love and the cognitive development of babies.
Even if you know some psychology, this course connects the dots in a way that provides a cohesive mental model for understanding the human mind. You’ll learn why you have irrational fears, how your memory works (and fails), and what science can tell us about the origins of happiness and morality.
13. John Mearsheimer’s “The Tragedy of Great Power Politics” – A Sobering View of Global Affairs
For anyone interested in geopolitics, Professor Mearsheimer's lectures on his theory of "offensive realism" are essential and deeply unsettling. He argues that the structure of the international system—the absence of a global 911—forces great powers to compete for dominance, not because they are inherently evil, but because it is the only rational way to ensure their survival.
This is a worldview-shattering take because it provides a powerful, structural explanation for conflict that transcends the personalities of individual leaders. It’s a sobering and often pessimistic framework, but it provides a clear-eyed mental model for understanding the enduring logic of international relations.
14. Esther Perel’s “Rethinking Infidelity” – A New Perspective on Love and Desire
Therapist Esther Perel’s TED Talk is a masterclass in challenging conventional wisdom. She explores infidelity not just as a symptom of a failing relationship, but as an expression of longing, loss, and a search for a new self. It’s a deeply compassionate and nuanced perspective on a highly charged topic.
This lecture provides a new mental model for understanding relationships. It moves beyond a simple framework of "good vs. bad" and "victim vs. perpetrator," offering a more complex understanding of human desire, identity, and the intricate dance of modern love.
15. Alan Watts – “The Nature of Consciousness” – Blurring the Lines of the Self
While not a traditional university professor, Alan Watts was a brilliant philosopher who specialized in translating Eastern thought for a Western audience. His recorded lectures are intellectual masterpieces that play with the very concept of the self.
Watts’ core worldview-shattering idea is that our sense of being a separate "ego" locked inside our skin is a fiction—a social convention. He uses logic, wit, and metaphor to guide you to the feeling that you are not just in the universe, you are the universe. It's a perspective shift that can reduce anxiety and foster a deep sense of connection.
16. Sam Harris’s “The Moral Landscape” – Can Science Determine Values?
Neuroscientist and philosopher Sam Harris delivers a powerful and provocative argument that science can, and should, be used to determine human values. He contends that "well-being" is a measurable state of the brain and that some actions and beliefs are demonstrably better at promoting it than others.
This lecture directly challenges the age-old idea that science and morality occupy separate domains. It’s a worldview-shattering proposal that suggests we can create a universal system of ethics based on evidence and reason rather than ancient texts or cultural relativism.
17. Randy Pausch’s “The Last Lecture” – An Engineering Approach to Life
When Carnegie Mellon professor Randy Pausch was diagnosed with terminal cancer, he delivered a "last lecture" that wasn't about dying, but about living. It's a profoundly moving and incredibly practical talk about achieving your childhood dreams, overcoming obstacles, and enabling the dreams of others.
The mental models Pausch offers are priceless: treat time as your only finite commodity, understand that brick walls are there to show you how badly you want something, and focus on fundamentals. It's an engineering-inspired operating system for a life well-lived, and it will leave you both inspired and equipped to take immediate action.
Your Intellectual Upgrade Awaits
Learning isn't just about downloading facts into your brain. It's about fundamentally upgrading the software you use to process reality. Each of these lectures offers a powerful new mental model—a new lens through which to see the world. By engaging with these ideas, you're not just getting smarter; you're becoming a more nuanced, empathetic, and effective thinker.
My challenge to you is simple: don't just bookmark this list. Pick one lecture that intrigues or even threatens your current worldview, and commit to watching the first episode this week. True growth begins at the edge of your intellectual comfort zone.
