AI时代,管理者需要补一补数学思维
3 6 Ke· 2026-01-09 01:17
随着人工智能的兴起,企业领导者或许会思考:是不是该把数学计算工作外包给机器,好让管理者们腾 出精力去做更多管理方面的事务呢? 答案是:绝对不行。 数学是商业的核心语言。对于企业领导者而言,流利掌握这门语言比以往任何时候都更为重要。事实 上,从首席执行官到仓库经理,几乎所有职能岗位和层级的人员都概莫能外。套用查理·芒格的话来 说:不懂数字就做商业决策,无异于绑着一条腿去战斗,结局肯定好不了。 的确,人工智能在数学领域有着令人瞩目的能力。大型语言模型(LLMs)在数学竞赛中取得了优异成 绩,而人类在这方面似乎正朝着相反的方向发展。乍一看,这似乎是一种严重的不对等,对人类来说堪 称 "游戏结束"。但事情并非如此简单。 人工智能尤其擅长为精确表述的问题找到确切答案,桑乔伊·马哈詹将这种能力称为 "学术性" 数学。然 而,商业数学却有所不同。它需要针对现实生活中模糊、多变且棘手的问题,提供实用、近似且灵活的 解决方案。这类问题暴露了人工智能的弱点,同时也彰显了人类推理、创造力和常识的优势。 你无需能够创作出莎士比亚式的诗篇,也能讲一口流利的日常英语。同样,你不必能够精确求解微分方 程,也可以掌握实用的商业数学。但你绝对 ...

神译局是36氪旗下编译团队,关注科技、商业、职场、生活等领域,重点介绍国外的新技术、新观点、新风向。 编者按:在概率思维模式下,玩好概率游戏,我们就能大大提升成功的可能性。本文来自编译,希望对您有所启发。 假设你设定了一个目标:在90天后跑完一场马拉松。你聘请的教练坦言时间并不充裕,但只要严格遵循训练计划、营养方案和睡眠安排,比赛当天你就能做 好准备。她警告说,若在任何一个环节偷懒,三个月内你将无法完成马拉松赛程。 假设你对自身执行力充满信心:坚持训练计划的概率70%,遵守营养方案的概率70%,遵循睡眠安排的概率同样是70%。那么同时达成三项并以最佳状态参 赛的概率是多少? 答案令人惊讶:仅34.3%。成功需要三个先决条件,单独看每个条件实现概率似乎很高,但必须三者同时达成。当我们将每个步骤的成功概率相乘时,前景 就不再那么乐观了。 这还只是个相对简单的目标。只需三件事顺利即可达成。现在想象更复杂的挑战,比如创办成功企业或取得梦寐以求的升职加薪。那么,十家企业中九家失 败的现象,以及多数人新年决心屡屡落空的常态,便不再令人惊讶。我们并非运气不佳,而是遭遇了宏大目标与低概率交织的必然失败。但这不是放弃的理 由, ...
像科学家一样思考丨书评

潜在亏损与盈利的概率及其对应金额的精确加权之上。这一算法虽然看起来单线条甚至有些简单,但却不失睿智,亦有定量分析的支撑。在商 业决策和投资领域,这种大概率思维必不可少,绝不可以忽略概率分布。 这本书有意思的一点还在于它并不是用深奥的数学公式来论证自己的观点,而是运用某种"降维打击",结合人们日常的一些思维惯势娓娓道 来,例如"糟糕的结果并不意味着拙劣的决定",这很容易理解,就是说人们有时习惯于"事后诸葛亮",用结果的好坏来倒推决策优劣,然而, 作者从概率学的严谨角度指出,这种归因方式存在严重的逻辑缺陷。因为,一个基于正确分析和大概率思维作出的好决策,仍可能会产生差结 果,同理,一个逻辑混乱的甚至是拍脑袋的坏决策,也可能因为偶然的好运气而得到不错的结果。书中也举了个简单的例子,天气预报说明天 有70%概率会下雨,如果第二天没下雨,你不能就此而说天气预报毫无用处。这毕竟是一个关乎概率的事件。所以,包括商业决策在内的各类 决策者,需要坚持大概率思维、模型和理性决策,识别一些随机性干扰带来的不同结果,不要因结果来反证决策的好坏。否则,对错误经验的 过度总结和痴迷会令你错过正确路径。 文/夏宁 "用亏损的概率乘可能亏损 ...
