How to Make a Difference: Part 2

Think about the last time you had a discouraging thought. Maybe you told yourself, "This won't work. I'm not cut out for this." Did you take that thought as fact? Last week, we talked with psychologist Martin Seligman about why some people come to believe that their actions don’t matter. In the second part of our conversation, he explains how we can strengthen our sense of agency, learn to see new possibilities, and build confidence in our ability to shape what happens next. Anyone who has struggled with depression knows that it feels terrible. But is there a point to that terrible feeling? We consider a new way of thinking about depression in our latest YouTube video -- check it out, and be sure to subscribe so you don't miss our future videos. Hosted by Simplecast, an AdsWizz company.

How to Make a Difference: Part 1

Why do some people act on the possibilities before them, while others come to believe that nothing they do will make a difference? Psychologist Martin Seligman describes his groundbreaking research on learned helplessness, and explains how the stories we tell ourselves about setbacks can shape what we do next. We also explore how optimism can help us rediscover our ability to change things for the better. If you have a question or comment about the science of optimism and pessimism that you'd be willing to share with the Hidden Brain audience after listening to this episode, please find a quiet room and record a voice memo on your phone. Email the file to us at feedback@hiddenbrain.org. Use the subject line: “How to Make a Difference.” If you love Hidden Brain in audio, check out our video series on YouTube.

刨根问底：时间到底是什么？它真的存在吗？

这一期我们来碰一个我长期想聊的话题：时间。这期结合前两期的科幻故事《递归》，形成了一个时间与人类记忆关系的小系列，推荐你一起听。前两期分别是：曼德拉效应和既视感，是被抹除的另一段时间线：《递归》的科幻故事当人类掌握了篡改时间的能力，世界开始崩塌：《递归》故事的完结这期我们不再聊故事，而是回到真实的物理世界。你有没有想过——钟表，真的在测量时间吗？它到底是怎么测算时间的呢？如果把整个宇宙里的一切按一下暂停键，冻结一亿年，然后再解冻，这一亿年，算过去了吗？小时候的一个暑假很漫长，而现在的日子，一年嗖的一下就过去了，如果我告诉你，这不是心理学问题，而是涉及到了意识和时间关系的本质呢？如果说时间在哗哗地流动这件事，它本来只存在于我们的意识里呢？这些问题，有的看似是抬杠，有的看似是科幻，但它们全都是正经物理学和神经科学吵了几百年的真问题。今天我们就要聊这些，这一趟走下来，你关于时间的一切直觉——它在流、它有现在、它对所有人是公平的——可能一个都保不住。 P.S：这是一期按照付费节目质量准备的内容，最后决定免费开放，给更多喜欢时间这个神秘话题的朋友，感谢你的倾听，也欢迎你的打赏鼓励。

#743.Instinct 创始人：个人 AI 助手应该站在用户这边

📝 本期播客简介本期我们克隆了：Invest Like The Best · Inside the Personal AI Assistant Growing 10% a Day | Instinct Founder 原内容更新时间：2026-09-28 不用打开新应用，只发一句话，AI 就能替你订旅行、安排日程，甚至把不想要的订阅从头到尾取消。 Invest Like The Best 主持人 Patrick O'Shaughnessy 与 Instinct 创始人兼 CEO Noah Shinn，聊这款通过消息、语音和邮件与用户互动的个人 AI 助手。Noah 分享了用户把信用卡交给 Agent 前如何建立信任、Instinct 如何从交易中获得收入，以及产品每天增长约 10% 带来的算力难题；他也谈到，未来软件可能不再是一个个独立应用，而是越来越简单的交互界面。 👤 本期嘉宾 Noah Shinn 是 Instinct 的创始人兼 CEO，大约一年前创办这家公司，正在打造一款无需安装新应用、可以通过手机和电脑替用户办事的个人助理。他从产品设计、用户信任与安全机制，到交易模式和算力扩张，亲自讲述了这款产品如何从早期使用场景走向更广泛的日常服务。 ⏱️ 时间戳 00:53 个人Agent走进生活 12:27 Agent重塑旅行与预订 19:09 信任与商业模式 31:44 企业如何迎接Agent 40:09 打造令人喜爱的助理 44:47 增长、算力与未来 🌟 精彩内容 💡 用户把信用卡交给 Agent，信任才刚刚开始使用三周后，40%的用户已经把个人信用卡分享给 Instinct；至少接入一项敏感信息的用户，留存率约为80%。Instinct 还会用独立于 Agent 的系统拦截恶意内容，并监控、批准或否决 Agent 的行动。 "用户始终应该觉得自己的数据由自己掌控。" 💡 AI 助手不该靠操纵用户赚钱 Noah 不希望 Instinct 通过广告或其他方式诱导用户购买不想要的东西。他认为，Agent 的职责不只是照着指令完成任务，还要理解用户更高层次的目标，并在用户真正需要时替他们兜底。 "Instinct 应该站在用户这边，按照用户的意愿行事。" 💡 增长越快，算力越难买 Instinct 每天增长约10%，而算力需要提前数月采购，临时购买的价格可能贵到原来的3到4倍。若增长持续，团队就得在买少了可能不够用、买多了又承担巨大成本之间做判断。 "如果底层算力需求也得跟着每天增长10%，那该怎么办？" 💡 软件可能不再需要一个个应用未来用户或许只要说“我今晚得去纽约”，Instinct 就能找航班、订酒店、衔接日历和叫车。Noah 认为，界面会越来越简单，但 Agent 能力不会因此受限。 "我觉得所有软件最终都会归结为一个非常简单、非常容易使用的界面。" 💡 主动服务会把办事阻力降到接近零如果 Agent 知道用户的日程和偏好，就能提前安排出行，或在用户到家前问要不要点熟悉的外卖。Noah 认为，操作门槛降低后，用户和商家的互动反而可能更多。 "如果是主动帮你处理事情，阻力就真的为零。" 🌐 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

A fall mystery: why do only certain leaves turn red?

Leaves turn yellow in the fall because Chlorophyll breaks down, revealing the yellow pigment that was there all along. But why red? Red is a different story altogether. Leaves have to make a new pigment to turn red. Why would a dying leaf go an extra mile to do that? Scientists don’t really know. NPR science correspondent Nell Greenfieldboyce reports on the leading hypotheses out there. Read more of Nell's reporting on this topic. Interested in more seasonal science?

How to Read a Room Like a Pro & The Surprising Truth About Self-Esteem

If you’ve ever tried to look at your phone while wearing sunglasses and found the screen strangely dark—or even completely black—there’s a fascinating reason why. And you don’t necessarily have to take off your sunglasses to fix it. Listen and discover a very simple trick. https://www.allaboutvision.com/eyewear/sunglasses/lenses/polarized-lenses-and-lcd-screens/ Imagine walking into a meeting, party or conference and quickly figuring out who has influence, who knows whom, who feels uncomfortable and what is really going on beneath the surface. That’s the skill of “reading the room.” Some people seem naturally good at it, but it turns out the rest of us can learn it too. Pamela Meyer explains what to watch and listen for—and how becoming a better social observer can give you a real advantage at work and in everyday life. Pamela is an expert in deception and human behavior, a Certified Fraud Examiner and founder and CEO of Calibrate. She is author of How to Read the Room: The Art and Science of Social Observation(https://link.amazon/B07AOq218). Most of us assume that good self-esteem comes from feeling positive about ourselves. But trying to convince yourself that you’re wonderful may not work—and can sometimes make you feel worse. So where does genuine self-worth actually come from? Psychologist Dr. Marisa Franco explains the surprising science of self-esteem, why compliments and positive self-talk don’t always have the effect we expect, and what actually helps us feel more secure in ourselves and our relationships. Marisa is a professor at the University of Maryland and author of Worth: The New Science of Self-Esteem and Secure Attachment (https://link.amazon/B01yeoZk0). There is an unmistakable smell when you walk into an old bookstore or open a book that has been sitting on a shelf for decades. Where does that “old book smell” actually come from? Even more interesting is why so many people find it so pleasant. It turns out there’s some intriguing chemistry—and psychology—behind it. https://www.mcgill.ca/oss/article/did-you-know/why-do-old-books-smell-so-good PLEASE SUPPORT OUR SPONSORS MONARCH: Write your own money story with Monarch!

#741.All-in｜Meta Muse：AI 助理第一次替普通人办事

📝 本期播客简介本期我们克隆了：All-In Podcast · Anthropic IPO at Risk, Meta’s Muse Pop, Token Prices Fall, Open Source Gains Share, Alignment Fails 原内容更新时间：2026-09-26 All-In 播客第 290 期由 Jason Calacanis 主持，David Friedberg、Chamath Palihapitiya 和电话连线的 David Sacks 参与讨论。节目先回顾 All-In Summit，再从 AI 公司该不该被称为“实验室”、产品责任和安全边界，聊到开源模型快速增长、token 价格下跌，以及 Anthropic 和 OpenAI 的 IPO 压力。本集一个重要判断是：模型能力趋同、开源选择增多后，单靠转售 token 的价值会减弱，AI 公司必须往技术栈上层走；与此同时，Meta 的 Muse 和 Grokbot 这样的个人 AI Agent，正在把 AI 变成普通人能用来处理邮件、预订行程、购物和省钱的工具。节目后半段还讨论了 alignment 应该对齐谁，以及 Anthropic 新建 wet lab 的用途与风险。 👤 本期嘉宾本期由 All-In 播客核心四人组对谈：Jason Calacanis 担任主持；Chamath Palihapitiya 和 David Sacks 参与 AI 公司责任、IPO、监管与市场竞争等议题；David Friedberg 则从模型发布、生命科学应用和实验室研究等角度分享看法。Friedberg 提到自己负责一个生命科学研发机构，并以 Ohalo 为例谈实验室与公司的关系；他也介绍了 Anthropic 生命科学模型和 wet lab 如何用于验证 AI 对蛋白质、酶的预测。 ⏱️ 时间戳 00:28 峰会最难忘时刻 04:34 责任、竞争与实验室之名 18:49 非前沿模型与成本 28:04 IPO延期与开源压力 49:21 前沿发展与政治反应 1:03:07 Muse、alignment与甲骨文 1:21:20 Anthropic生物研究与实验室 🌟 精彩内容 💡 AI 公司是公司，就得为产品负责讨论从 frontier labs 是否应该享有特殊保护展开。嘉宾认为，称自己为“实验室”不能改变营利公司的本质；决定是否发布产品的责任，应该由真正做决定的公司承担，而不是寄望于全球治理机制。 "它们是公司，就得按同一套标准接受评判，包括产品责任。" 💡 模型越来越像，真正的差距可能在 harness 模型性能逐渐趋同，不代表产品体验也会趋同。Chamath 指出，模型要配上能让它调用工具、完成任务的 harness，才能成为 agentic 的产品；公司与个人接下来要判断，究竟值得为什么付费。 "模型正在趋同，但 harness 之间差异很大，所以它们的表现差别也很大。" 💡 token 变便宜，AI 公司得往技术栈上层走当模型之间的差异缩小、Open Source 和 open weights 模型越来越能打，单纯卖 token 或在模型外层做封装，可能不再创造足够价值。节目认为，Anthropic 和 OpenAI 需要把能力延伸到网络安全、法律、客户支持等实际业务中。 "你不能一直提供价值不断下降的 token，因为之后的价值都会被那些封装你们智能 token 的人吸收，并由他们创造出来。" 💡 AI 的大部分价值，不只是替代旧工作 Friedberg 认为，AI 的高价值不止是把已有流程做得更便宜，还包括让过去做不到的发现与创造成为可能。高端模型能否持续收费，取决于它们是否能在生命科学、工程等复杂领域带来新的成果。 "AI 价值的 99% 在于让人类历史上从未可能实现的事情成为可能。" 💡 Muse 把个人 AI Agent 带进日常生活节目嘉宾将 Muse 视为降低 AI 使用门槛的产品：它把复杂功能装进简单界面，可以帮助用户筛选邮件、订机票和酒店。个人 AI Agent 若能稳定处理日常事务，就不只是技术爱好者的玩具，而可能成为普遍可用的数字助理。 "如果有 10 亿人开始把个人 AI Agent 当作数字助理，用来让生活更有效率，那会怎么样？" 💡 alignment 也可以从用户需求出发节目质疑，若 alignment research 连要对齐什么都无法达成共识，抽象地讨论伦理原则未必能让产品更可靠。另一种更务实的思路是，让模型行为可预测、安全，并符合实际使用者的需求。 "在我看来，alignment 就应该是满足客户的需求，就像其他任何产品一样。" 💡 Anthropic 的 wet lab 是用实验验证 AI 预测 Friedberg 解释，Anthropic 的实验室旨在把模型对新酶、蛋白质功能的预测放到真实实验中检验。节目提到，这类基础实验室通过制造蛋白质并观察其功能，验证软件预测是否成立；这与制造病毒或病原体并非一回事。 "我觉得，归根结底，他们的目标是拿到一些证据，证明自己的软件确实能做到它所预测的事情。" 🌐 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
