Tim Harford: 作为讲述者,我通过“微笑者”过山车事故,探讨了在自动化系统日益普及的今天,我们应该如何在信任机器和依赖人类判断之间做出选择。我强调事故并非由过山车或自动化系统本身引起,而是由于工程师团队未能充分理解系统运作原理,以及缺乏明确的沟通和检查流程。我引用了保罗·米尔的观点,即当我们掌握了算法无法获取的信息时,才应该考虑推翻计算机的决策,但前提是我们必须真正理解计算机的工作方式。在排队乘坐“微笑者”时,我虽然鼓励儿子体验,但最终还是选择了不坐第一排,这反映了我对风险的重新评估。 Leah Washington: 作为事故的亲历者,我描述了乘坐“微笑者”过山车时的经历,包括最初的兴奋、等待时的焦虑,以及事故发生时的恐惧和痛苦。我讲述了自己在事故中失去左腿的悲剧,以及事故后艰难的康复过程。我的经历突显了人为失误可能造成的严重后果,以及在安全流程中进行充分检查的重要性。尽管遭遇了不幸,但我依然积极面对生活,成为了一个Instagram网红,这展现了我坚强和乐观的一面。 Stephen Flanagan: 作为过山车安全专家,我指出公众普遍认为过山车的危险在于脱轨,但实际上,火车相撞才是更大的风险。我的观点强调了在过山车安全设计和运营中,预防碰撞的重要性,以及自动化系统在避免这类事故中的作用。 Paul Meehl: 作为心理学家,我长期研究专家判断的局限性,并提倡在某些情况下,使用简单的公式化流程来替代人类专家的判断。我提出的问题“我们何时应该用自己的头脑代替公式?”在今天仍然具有现实意义,提醒我们在依赖自动化系统的同时,也要保持批判性思维,并充分理解系统的运作原理。

Shownotes Transcript

Leah Washington and her new boyfriend Joe Pugh are on their first day out together. They're at Alton Towers theme park, where they've chosen to ride the "Smiler" rollercoaster: a terrifying tangle of track that loops and swoops through a world-record 14 inversions. Leah and Joe are seated right at the front of the train and, as they reach the highest point of the ride, they steel themselves for the drop. But then, quite suddenly, the ride stops.

Down on the ground, the computer system that controls the rollercoaster is warning that another carriage is out on the track, right in the path of Leah and Joe's train. The engineers are certain the computer is wrong...

Algorithms are often faster and cleverer than humans, and they can help us avoid accidents. But computers *can *make mistakes. When should we trust our own heads, instead of the machine?
