从哈雷到AI:当量化成为信仰,我们离真相更近了吗?
伍治坚证据主义· 2025-11-11 02:35
当哈雷在伦敦皇家学会的档案中看到那份 《布雷斯劳死亡记录》 时,立刻被吸引住了。里面密密麻麻地记录着几千个名字、年龄和死亡年份,仿佛是一部 城市的生命日历。哈雷用了几个月时间,把所有数据重新整理、分类,计算出每个年龄段活下去的概率。比如,一个五岁孩子活到十岁的概率是多少,一个 四十岁的人再活二十年的机会有多大。 1687年 ,在德国西里西亚的布雷斯 劳城(今天波兰境内的弗罗茨瓦夫), 有一位叫卡斯帕·诺依曼的牧师。他身材瘦削,说话温和,是那种一辈子都不 会被历史记住的人。他的日常工作很简单:主持洗礼、婚礼和葬礼,在教堂的账本上,一丝不苟地记录每一个新生命的诞生,也记录每一个灵魂的离开。 那时候的欧洲,还没有现代意义上的统计机构。政府不知道自己管辖的地区有多少人口,更不知道每个人平均能活多久。瘟疫、战争、饥荒,让生命变得脆 弱又短暂。诺依曼并不是科学家,他只是出于一种牧师的本能,相信在上帝面前,每一个生命都值得被记录。于是,他把教区里每一次出生与死亡都写下 来,精确到年龄、性别,甚至死因。在大雪纷飞的冬天,他照样披着斗篷,走到墓地确认死者信息;到了来年的春天,在每个婴儿接受洗礼的时候,他又会 在圣水旁写下孩子的 ...

1960年,一个叫 Simulmatics 的公司在美国诞生。它的创始人叫艾蒂尔·德·索拉·普尔(Ithiel de Sola Pool),是麻省理工大学的政治学家,信奉"只要 数据够多,人类行为就能被预测"。这家公司后来被称为"硅谷的祖父",他们最早提出的口号是——" 用模型预测人心 "。 1960年美国总统大选,年轻的民主党候选人约翰·肯尼迪遇上了资深的共和党人尼克松。为了缩小差距,增加自己的胜算,肯尼迪团队找到了 Simulmatics,希望借助计算机和民调数据预测选民行为。当时麻省理工教授普尔与广告人爱德华·格林菲尔德和心理学家罗伯特·阿贝尔森共同创办 Simulmatics 公司。他们从盖洛普等民调中提取十万份问卷,用IBM打孔卡录入,建立了当时美国最大的政治数据库。Simulmatics把选民分成480个"心 理单元",比如"中西部农村、低收入、新教女性",又把选举议题划为五十种变量,如"就业"、"通胀"、"种族"、"宗教"等。所有这些数据被录入位于哥伦 比亚大学的IBM 704计算机。 1960年8月,肯尼迪团队正式雇用Simulmatics。公司连夜赶制报告,管理层在8月25日带着成果在罗伯特 ...

2008年金融危机爆发后,公众对金融行业充满愤怒,要求"有人付出代价";政治人物、检察机关与媒体都需要一个能代表"贪婪银行家"的符号。于是,一 个在日本办公、操纵利率的英国交易员,成了最合适的替罪羊。 但九年后,剧情逆转。 2024年7月25日,英国最高法院推翻了这项判决,宣布原审不公,理由是陪审团在法官误导下被剥夺了判断"被告是否存在不诚实"的权力【2】。判决书看 似枯燥,却动摇了英国金融犯罪司法的根基。它恢复了刑法中最古老的原则: Mens Rea ,即" 罪行不仅在于行为,更在于心念 "。 由于这是一个典型的金融犯罪案件,同时它在历经九年时间后被英国最高法院逆转,因此值得我在这里向我的读者朋友们详细介绍和解释一下。 首先,让我先为大家科 普一下什么是 Libor。 LIBOR的全称是 伦敦银行间同业拆借利率(London Interbank Offered Rate) ,曾是全球金融市场最重要的基准利率之一。简而言之,Libor是大型国 际银行之间在无担保条件下相互借钱的平均成本。也就是说,LIBOR代表了"全球资金的批发价格"。 Libor的影响范围极其广泛。全球超过 300万亿美元 的金融合约(包括 ...
为什么你没亏钱,却变穷了?

Core Viewpoint - The article discusses historical instances of debt management through inflation and the implications for modern economies, particularly focusing on France's "two-thirds bankruptcy" in 1797 and Japan's prolonged economic stagnation since the 1990s, highlighting how governments can manage debt without outright defaulting [2][7][10]. Group 1: Historical Context of Debt Management - In 1797, the French government reduced the value of government bonds by 67%, leading to significant losses for bondholders, a situation referred to as "two-thirds bankruptcy" [2]. - France's financial crisis was rooted in excessive debt accumulation due to continuous wars and ineffective tax reforms, resulting in a national debt of 5 billion livres by 1788, with interest payments consuming half of tax revenues [2][3]. - The introduction of the Assignat paper currency in 1789, initially backed by confiscated church lands, led to rampant inflation, with its total issuance reaching over 45 billion livres by 1796, nearly ten times France's GDP [3][5]. Group 2: Economic Consequences of Inflation - The inflation primarily affected the urban middle class, leading to protests and a loss of confidence in the currency, culminating in the abolition of the Assignat system in 1796 [5][6]. - The radical debt reduction plan proposed by Finance Minister La Meillur in 1797 effectively reduced France's debt-to-GDP ratio from 120% to below 40%, allowing the government to regain borrowing capacity [6]. - The aftermath of the debt reduction saw the "interest class" suffer significant losses, while the government stabilized its finances, illustrating the harsh realities of economic recovery post-crisis [6][14]. Group 3: Modern Parallels in Japan - Japan's economic situation post-1990 mirrors France's historical experience, with a debt-to-GDP ratio exceeding 250%, the highest globally, yet maintaining low bond yields due to the Bank of Japan's monetary policies [7][9]. - The implementation of "Abenomics" in 2013, particularly through aggressive monetary easing, has allowed the government to manage its debt without triggering market panic, effectively achieving a form of "implicit default" [7][9]. - Current inflation rates in Japan reached 3.1% in 2023, while bond yields remained low, resulting in negative real returns for investors, akin to the historical experiences of the French middle class [9][11]. Group 4: Lessons and Insights - Governments can manage debt through inflation rather than outright default, as seen in both historical and modern contexts, allowing for a "silent wealth transfer" from creditors to debtors [11][12]. - Investors should focus on real returns after accounting for inflation, as nominal returns can be misleading, with historical examples illustrating the erosion of purchasing power over time [12][13]. - Economic recoveries post-debt crises can be prolonged, with structural adjustments taking decades, as evidenced by both France and Japan's slow paths to recovery following their respective financial upheavals [14][15].

Group 6: Critical Reflection - While the article acknowledges the successes of Britain's institutions, it also points out the darker aspects of industrialization, such as exploitation and inequality, reminding that progress often comes at a cost [15][16].
