长寿奖励为什么不受欢迎?
伍治坚证据主义· 2025-11-21 00:24
我们不妨做一个简单的推算:如果奖金池中的一半人去世,幸存者拿到的名义票息率就会翻倍,从7%上升到14%。如果只剩四分之一人,则升到 28%; 若只剩十分之一,年息理论上会达到 70%。你越长寿,越到后面,回报就越像火箭一样往上飙。 问题在于,能活过别人的概率有多高呢?按照1693年的寿命表显示,一个30岁的人平均能再活30年,到60岁左右去世。但那只是"平均值",并非一半人 能活到60岁。事实上,到60岁 时,大约有三分之一的人仍在世,而三分之二的人已不在人间。 1693 年的伦敦,街头空气里混着煤烟、马粪味,还有战争的焦灼气息。当时的英国正与法国打得不可开交,国王威廉三世为了筹措战争经费,可谓绞尽 脑汁。为了应对日益恶化的财政赤字,英国议会一边加税,一边费尽心思想出各种奇奇怪怪的融资办法。 就在这样的背景下,一个新奇的金融发明登上舞台: 唐蒂( tontine)。它的名字来自一个意大利银行家洛伦佐·唐蒂(Lorenzo Tonti),他发明了一种 听起来像是"投资+游戏+寿命赌局"的产品。听上去有点复杂,但其实逻辑很简单:参与者每人出一笔钱组成资金池,政府承诺每年支付利息。起初大家都 分红,但每当一个参与者 ...

如何理解战略背后的科学?

在制定战略时,CEO和高管总是"一言堂",一线人员反馈的结果也听不进去,嘴上说大方向让大家一起 想一想,实际则是自己说了算,咨询公司的人也只能在一旁陪笑,其他部门的人也不敢说什么,都怕得 罪CEO。 企业内部在制定战略时,你可能遇到过这种情况: 其实,这些问题涉及到的方面特别广,在这个"战略咨询"全网飞的时代,几乎很少人会提及,因为这其 中包括了:心理学、组织心理学、决策学、社会心理学、行为经济学等学科,非常广泛,并不是某一个 学科能解决的。这是由CEO的心理与团队成员的心理、企业发展利益者共同组成的复杂综合体,想要解 决这其中的矛盾,就必须了解所涉及的所有学科,才有可能改变CEO、组织的思想。 我自己也希望研究一些冷门赛道,找出我的"细分领域",最关键是要对企业发展有益的方向。 比如,我感兴趣的问题是:高管如何制定战略决策?我如何能更好地训练有志于成为战略家的人员熟练 掌握这一"技术"?相对于"战略",我还是更喜欢研究"人";这两者密不可分,所以我选择了研究"战略 决策中的人"。 昨天,在研究战略时,发现一位战略管理学教授正在努力证明好的战略背后的方法;这个研究关于组织 认知、记忆和专业知识的研究,旨在启发 ...

Group 1 - The article discusses the evolution of science and its relationship with human existence, highlighting a crisis in scientific understanding and its implications for society [3][4][18] - It emphasizes the need for a new scientific worldview that reconnects science with direct human experience, moving away from the traditional dichotomy of subjectivity and objectivity [21][27][28] - The authors argue that the current scientific crisis stems from a "blind spot" in scientific philosophy, which prioritizes abstract mathematical concepts over direct human experience [9][10][15] Group 2 - The article outlines the significance of social sciences in understanding reality as constructed through shared human experiences, emphasizing the concept of intersubjectivity [22][24] - It critiques the tendency in both natural and social sciences to abstract and separate research from direct human experience, which can lead to a misunderstanding of social realities [24][29] - The authors propose that integrating direct experience into scientific inquiry can lead to a more nuanced understanding of social constructs and the mechanisms behind them [27][28][30]
