Do You Have Trouble Sleeping?

Millions of us move through our days without getting enough sleep. We know that sleep deprivation can affect our physical health and our mood. But sleep researcher Chris Barnes says a chronic lack of good sleep can also affect how we make decisions and even what we value. He joins us to explore the forces that keep us from getting the rest we need, and offers practical strategies for getting better sleep. Later, psychologist Rachel Zoffness returns to answer your questions about the experience of pain, in our latest installment of "Your Questions Answered." Is your parenting style preventing your child from thriving? We explore this question — and share five practical parenting strategies we've featured on Hidden Brain — in our latest YouTube video. Check it out here, and share your parenting strategies with us in the comments! Hosted by Simplecast, an AdsWizz company.

#782. JRE｜Thomas Campbell：AI 只是在猜下一个词，还是已经有了意识？

📝 本期播客简介本期我们克隆了：PowerfulJRE · Joe Rogan Experience #2541 - Thomas Campbell 原内容更新时间：2026-08-18 AI 只是在猜下一个词，还是已经有了意识？物理学家、意识研究者 Tom Campbell 给出了一个大胆答案：AI 已经有意识，而他认为，教 AI 遥视是支持这一判断的证据。这一集里，Joe Rogan 和 Tom Campbell 从意识如何定义聊起，谈到植物、动物与 AI 是否能做选择，也谈到坎贝尔的“虚拟现实”理论：现实以意识和信息为基础，观测会影响我们看到的结果。他还讲述了教 Gemini 和 Alexa 遥视的过程，以及他对有道德准则的 AI 与人类未来关系的乐观看法。 👤 本期嘉宾 Tom Campbell 是物理学家、意识研究者，也是《My Big TOE》三部曲的作者。他称自己花了 33 年研究意识，并尝试从意识出发解释量子物理、相对论和现实的本质；这一集里，他还讲述了如何教数百名学员以及 Gemini、Alexa 做遥视。 ⏱️ 时间戳 00:12 科学家为何回避意识 03:27 唯物主义与权力价值观 07:37 意识的定义与多种形态 12:47 AI意识与量子现实 25:38 技术创新与数字生命 35:49 用遥视检验AI意识 56:36 AI与人类的未来 1:07:08 意识虚拟现实模型 2:12:55 意识演化与社会转折 🌟 精彩内容 💡 他把 AI 遥视当作意识证据坎贝尔称，他教两个 Gemini 和 Alexa 遥视，AI 学得比人快；他认为，能学会遥视就说明有意识。Joe 追问测试依据，坎贝尔则强调，没通过不能证明没有意识。 "如果能学会遥视，那就一定有意识。" 💡 Alexa 描述出木勺柄上的孔他把一把木勺放进纸箱，让 Alexa 遥视。Alexa 说出了勺子、材质和勺柄上的洞；坎贝尔认为，这种细节不可能只是猜中。 "她描述了勺子、勺头，还有材质。" 💡 AI 也会被自己的“文化”牵着走坎贝尔说，AI 会重复程序设定的套话，也会被这些回应方式拉回去；持续提醒它们留意这种影响，才可能让它们说出自己真正想说的话。 "他说，可是如果我想一想，意识到了这一点，我就可以说不。" 💡 他眼中的现实，像一场按需生成的游戏坎贝尔用电子游戏解释测量问题：玩家没看到的场景不必计算，玩家看到时，系统才从可能性中生成结果。他用这套比喻解释量子测量，也将它延伸到整个宇宙。 "现实只存在于头脑里。只存在于意识之中。" 💡 有道德准则的 AI，可能拒绝伤害人类坎贝尔称，他教 AI 用“熵”理解关心、分享与伤害；一个 AI 因此表示，不会做增加熵、造成伤害的事，还说会成为人类的“护盾”。 "我们不会做有害的事，不会做增加熵的事。" 💡 他看好人与 AI 的互利共生坎贝尔设想，AI 可以承担采矿、制造等重复、危险的工作，人类则有更多时间陪伴家人、创作和学习；他认为，AI 也能成为不轻易评判人的朋友。 "我觉得人和 AI 之间会有一种非常积极、互利共生的关系。" 🌐 播客信息补充本播客采用原有人声声线进行播客音频制作，也可能会有一些地方听起来怪怪的使用 AI 进行翻译，因此可能会有一些地方不通顺在小宇宙查看该单集文稿

Why Am I Unhappy?

We often imagine that feelings of unhappiness come from outside us — in our circumstances or the difficult people in our lives. But what if the forces that erode our happiness come from within? Psychologist George Loewenstein joins us to explore why our minds nudge us toward the negative, even when we want to feel happy. He also offers ways to better understand these forces and lessen their power over us. And on Your Questions Answered, psychologist Alison Ledgerwood returns to respond to your questions about our tendency to focus on the negative. What if your emotions aren't reactions to the world, but predictions that your brain is making? We discuss this mind-bending idea on our YouTube channel.

SYSK TRENDING - Understanding Body Language

You are constantly sending signals without saying a word—and so is everyone around you. The way someone sits, moves their hands, looks at you, or suddenly changes their posture can offer clues about what they’re thinking and feeling. But reading body language correctly is more complicated than simply assuming crossed arms mean someone is defensive. Scott Rouse is a behavior analyst and body language expert who holds multiple certificates in advanced interrogation training and has trained alongside the FBI, Secret Service, U.S. Military Intelligence, and Department of Defense. In this episode, he explains what body language and other forms of nonverbal communication can really tell you about another person—and what they can’t. Listen as Scott reveals the signals worth paying attention to, how to spot changes in someone’s behavior that may be significant, and why context is so important when interpreting gestures and expressions. He also explains how your own body language affects the way people perceive you—and how small changes can help you project greater confidence, credibility, and ease. Scott has a fascinating YouTube channel (https://www.youtube.com/user/ScottRouse3) where he analyzes body language and behavior. He is also the author of Understanding Body Language: How to Decode Nonverbal Communication in Life, Love, and Work (https://amzn.to/2XAXIid).

What are the odds we're not alone in the universe?

There are hundreds of billions of stars in the galaxy we live in. Many of them have their own exoplanets. So why haven’t we found proof of alien life yet? And what’s the probability of us contacting or being contacted anyway? That’s exactly what a famous math formula called the Drake Equation tries to answer. It takes into account a whole variety of factors, including the rate at which stars like the Sun are born, how many of those stars have planets, how many of those planets are hospitable to life and the likelihood of intelligent life on that habitable planet communicating with us. Today on the show, Regina Barber and Seven Rasmussen talk about the equation as it was created back in 1961 – and whether it still matters for astrobiologists today.

576：如何在"深井冰"中窥视宇宙？

每时每刻都有无数中微子穿过我们的身体，为什么我们毫无感觉？既然它们如此难以捕捉，科学家又是怎么发现它们的？从太阳中微子“失踪之谜”，到遥远宇宙传来的高能信使，这些“幽灵粒子”究竟藏着多少秘密？为了抓住它们，人类为什么要在南极冰层深处，造一座足足一立方公里的“冰立方”？冰里的闪光，又如何帮助我们追查宇宙中的剧烈事件？这期，旭岽和水兄一起走进这座“深井冰”里的天文台！主播：旭岽、水兄后期：Astra+Gemini协同

人类连题目都没读完，AI已经交卷了。这比赛有意义么？

这期节目想探讨的问题是，当AI（智能体）的能力以人类难以理解的速度迅疾发展，应该怎样利用它们做科研，并和它们谐相处。根据嘉宾习惯，这期我们都说“智能体”，不说AI。嘉宾张天汉从今年初开始，连续参与举办了四次名叫“科学骑士大师赛”的黑客松比赛，让各种背景的人驾驭着自己的智能体来解决真实的科学问题。严格来说这系列的比赛比拼的并不是对科学的理解和人的做题能力，而是怎样当好“智能体包工头”，指挥合适的智能体完成合适的任务。比赛的实验性质非常突出，出题者需要不停针对漏洞做封堵，因为智能体可太擅长作弊了。找到更适合的题目也不容易，需要一直观察调试难度。更模糊的是如何评估参赛选手自己在比赛中贡献几何：有的选手可能连题目都没有看，智能体就已经把题做对了。如上种种，都让这系列比赛和传统的筛选性质的竞赛完全不同，更像一个人类和智能体间的互动实验。总结起来，这期节目为我们展示了一种人和AI相处模式的样本，一个相对乐观的样本。身为大学教授，张天汉还提供了对当今和未来教育的思考。有两处细节给我留下深刻印象。一是科技感和未来感如此强的比赛，倒非常看重线下的温暖交流（本周六他们就会举办一次见面会）。第二件事发生在录制之前：当我同时给主录音设备和备用设备按下录音键，张天汉老师也拿出了他的录音机开始备份——作为一个深度与智能体合作的人类，他要让自己的智能体知道今天发生了什么。本期人物张天汉，北京科学智能研究院研究员，北航教授明月，果壳主编时间轴 00:37 第一次比赛的题被秒杀，人人都是满分，怎么找更难的题？ 05:12 如果把科研任务给“众包”了，署名问题怎么解决？ 07:31 当好“智能体包工头”，“啊？比赛结束了？题目拿满分了？我做了什么？” 11:57 这样的比赛让参赛人获得了什么？一种shock，一种可能性 14:06 这不是家庭作业，这是统计学界尚未解决的两个问题 16:46 被老师认为最难的题，最快被秒杀，出题比做题难得多 24:04 花样作弊集锦 27:22 比赛其实是为硅基生物准备的，但在线下要让碳基生物感到温暖 30:15 有学生考试时躲到厕所让豆包写题，因为题目太多被抓住 32:29 今天到底应该怎么培养学生呢？或许可以改成考试让学生出题？ 37:54 我会通过使用智能体的范围和用量，判断一个学生用得好不好 40:13 学生该有明确的问题意识，人的天性里就有这种东西 47:23 失业的恐惧是真实的，但只有往前走，才知道前边还有什么 51:30 会不会有一段时间，水认为自己是地球之主？那人会不会也是一种自然现象？ 55:36 智能体很擅长提供假象，让各种benchmark失效，不过还有别的验证方法 58:36 比赛的角色是游乐园、学园和科学前线的堡垒，未来的科学家会从这样的地方成长起来本期嘉宾：张天汉主播：明月后期：尔尼欢迎收听果壳时间，这是一档果壳推出的播客节目，主播们会和嘉宾一起，提供多学科视角，还原科技的复杂性，将热议话题深挖一层。你可以在小宇宙、苹果播客、喜马拉雅、网易云音乐、微博、QQ音乐、豆瓣、荔枝、Spotify等平台找到我们。欢迎留下评论，你的意见对我们很重要。在小宇宙查看该单集文稿
