  • America’s mass spiral of self-censorship | The Dilemma Ep. 1

    Americans no longer feel safe to speak their minds. The levels of self-silencing in the country rival that of Mccarthyism in the late 1940s – or higher, says research scientist Todd Rose. Our social trust is non-existent, so much so that many are opting out of sharing their opinions altogether, making way for those at the extremes to be the dominant voices.

    But just because the most vocal want something, doesn’t mean that the rest of the country shares this ideology. In fact, our brains mistake this extremist noise for consensus, reinforcing the lie that this is what we must believe.

    Here’s why this social silence must be changed. Why it's healthy to invite in other points of view – even if they differ from yours.

    This is The Dilemma with Irshad Manji, a series from Big Think created in partnership with Moral Courage College.

    About Irshad Manji:

    Irshad Manji is an award-winning educator, author, and advocate for moral courage and diversity of thought. As the founder of Moral Courage College, she equips people to engage in honest conversations across lines of difference.

  • Why we explore, even when there’s no payoff

    Astrobiologist Betül Kaçar believes science doesn’t always need a clear purpose; asking questions just to know is reason enough.

    Historically, scientific breakthroughs have come as a result of random, niche interests: questions asked just for the sake of satiating curiosity. For Kaçar, science is a patient act, and the simple desire to understand is one of the most beautiful parts of being human.

    Dr. Betül Kaçar is a University of Wisconsin-Madison professor and NASA-funded research leader exploring life’s early evolution. Her team has developed methods to uncover ancient biological innovations. She earned her Ph.D. In Chemistry from Emory and trained at Harvard in Evolutionary Biology.

    Peter Singer has been described as the world’s most influential philosopher. Born in Melbourne in 1946, he has been professor of bioethics at Princeton University since 1999. His many books include Animal Liberation - often credited with triggering the modern animal rights movement - Practical Ethics, The Life You Can Save, The Most Good You Can Do, and Ethics in the Real World. In 2023, he published Animal Liberation Now, a fully revised and updated version of the 1975 original.
    Singer’s writings have also inspired the movement known as effective altruism, and he is the founder of the charity The Life You Can Save.

  • Learn these 3 triggers to navigate conflict like an expert | Jefferson Fisher for Big Think+

    “What did you win? You won awkward silence. You won their contempt. You won the first to apologize. When you win an argument, you will lose their confidence, you will lose their respect, you will lose the connection.”

    What if every argument you’ve ever “won” actually cost you something way more valuable? Whether that be respect, connection, or trust, lawyer and author Jefferson Fisher argues that when you try to control the conversation, you end up losing something far more important.
    Instead of fighting to be right, Fisher invites us to unravel the tension of disagreement and examine the real triggers that lie beneath.

  • The last human choice: surrendering agency to AI

    The world creates moments when philosophy truly matters. This is one of those moments.

    As AI continues to make our lives more convenient, the temptation to use it to outsource judgment will also grow, threatening to erode human decision-making altogether. Brendan McCord, founder of Cosmos Institute, has spent his career advancing AI in the private and national security sectors. Led by a foundation in both technology and philosophy, he is proposing a new kind of technologist – a Philosopher-Builder – that could guide planetary-scale decision-making technology. According to McCord, approaching AI development with philosophical scrutiny is what will preserve our ability to live self-directed lives and flourish as humans.

    Chapters:

    01:10 – What happens when AI becomes life's autocomplete
    02:20 – Why philosophy is essential to building technology
    03:30 – Silicon Valley's lost moral ambition
    04:30 – Three types of builders holding us back
    05:45 – A new kind of builder: the philosopher-builder
    07:00 – Benjamin Franklin as the archetype
    08:30 – The future of AI and the case for human flourishing
    ----------------------------------------------------------------------
    About Brendan McCord:
    Brendan McCord is the founder and Chair of the Cosmos Institute and a key thinker at the intersection of AI and philosophy. In the private sector, Brendan was the founding CEO of two AI startups that were acquired for $400 million.

Brendan is a graduate of MIT and Harvard Business School and was a Visiting Fellow at St Catherine’s College at the University of Oxford. After MIT, he spent 610 days underwater on a submarine. He lives in Austin, TX with his wife and two children.

  • Sam Harris: Experience emotions without being consumed by them

    “You can be aware of sadness from a point of view that is not merely sad, and you can be aware of fear from a point of view that's not merely afraid.”

    Can consciousness serve as a refuge from suffering? By examining the raw textures of difficult emotions like anger and sadness, Sam Harris explains how we can experience them without suffering, and how digging into awareness reveals a layer of openness below the mental state.
    Harris explains how meditation and direct attention can alleviate pain and liberate us from a prison of our emotions.

    0:48 Reframing our mental state

  • Einstein failed to solve the Universe. Here’s what it would take to succeed. | Michio Kaku

    If Einstein couldn’t solve the theory of everything, could anyone? Physicist Michio Kaku explains what it would take.

    Albert Einstein spent the last 30 years of his life pursing a “theory of everything,” aiming to find a concise equation summarizing the fundamental laws of the Universe. His downfall? Subatomic particles.
    Physicist Michio Kaku offers an alternative to Einstein’s elusive theory: “string theory.” We could try to explain it, but he does a much better job. After all, he’s one of the co-inventors of it.
    If you aren’t sold on string theory, Kaku breaks down the three criteria needed to figure out what makes our Universe tick: it must incorporate Einstein’s theory of gravity, explain particle physics, and be mathematically sound. No pressure.
