How does a single decision tip the world into chaos? Why do intelligent leaders double down on choices that are clearly going wrong? What were they thinking? And if you were in their position, with limited information, pressure, and pride on the line, would you have done any better? In this smart yet playful discussion, we’ll explore 15 of the worst decisions in history and how they didn’t just fail… they changed everything. From the harsh terms of the Treaty of Versailles to Napoleon’s disastrous march into Russia and the shockwaves of Pearl Harbor, we’ll trace how certain moments spiraled into consequences no one could fully control.

But this isn’t just about what happened—it’s about why. Why do people persist with catastrophic choices even when warning signs are everywhere? What psychological forces—ego, fear, groupthink—keep bad decisions alive far longer than they should be? Together, we’ll unpack these turning points, debate which decision truly stands out as the worst, and reflect on what they reveal about human nature. Expect a conversation that’s thoughtful, surprising, and just playful enough to make even history’s biggest mistakes feel vividly alive.

一个决定，是怎么把世界一步步推向混乱的？为什么一些本来很聪明的领导者，会在明显出问题的情况下还坚持原来的选择？他们当时到底在想什么？如果换成你，在信息不完整、压力很大、还要顾及面子的情况下，你会做得更好吗？在这场既有思考也带点轻松感的讨论里，我们会一起看看历史上15个影响很大的错误决策——它们不仅仅是失败了，而是真的改变了很多事情的走向。从《凡尔赛条约》的苛刻条件，到 Napoleon 进攻俄罗斯的失误，再到珍珠港事件带来的连锁反应，我们会沿着这些关键时刻，看看事情是怎么一步步失控的。

不过这不仅是“发生了什么”的问题，更重要的是“为什么会这样”。为什么人在明显有风险的情况下，还是会继续做出可能带来严重后果的决定？像自尊、恐惧、群体思维这些心理因素，是怎么让一个本可以被及时调整的决策，一路发展下去的？大家会一起拆解这些关键节点，也可以讨论到底哪一个决定最“离谱”，以及这些故事到底反映了人性的哪些部分。这会是一场既有内容又不沉重的讨论，会有一些意外的角度，也会让那些历史上的关键时刻变得更具体、更有画面感。
