Nobel Prizes are commonly seen to be among the most prestigious achievements of our times. Based on mining several million citations, we quantitatively analyze the processes driving paradigm shifts in science. We find that groundbreaking discoveries of Nobel Prize Laureates and other famous scientists are not only acknowledged by many citations of their landmark papers. Surprisingly, they also boost the citation rates of their previous publications. Given that innovations must outcompete the rich-gets-richer effect for scientific citations, it turns out that they can make their way only through citation cascades. A quantitative analysis reveals how and why they happen. Science appears to behave like a self-organized critical system, in which citation cascades of all sizes occur, from continuous scientific progress all the way up to scientific revolutions, which change the way we see our world. Measuring the "boosting effect" of landmark papers, our analysis reveals how new ideas and new players can make their way and finally triumph in a world dominated by established paradigms. The underlying "boost factor" is also useful to discover scientific breakthroughs and talents much earlier than through classical citation analysis, which by now has become a widespread method to measure scientific excellence, influencing scientific careers and the distribution of research funds. Our findings reveal patterns of collective social behavior, which are also interesting from an attention economics perspective. Understanding the origin of scientific authority may therefore ultimately help to explain how social influence comes about and why the value of goods depends so strongly on the attention they attract.
诺贝尔奖通常被视为我们这个时代最具声望的成就之一。通过挖掘数百万条引文,我们对推动科学范式转变的过程进行了定量分析。我们发现,诺贝尔奖获得者和其他著名科学家的开创性发现不仅得到了他们标志性论文的大量引用的认可。令人惊讶的是,它们还提高了他们之前出版物的引用率。鉴于创新必须在科学引文中战胜强者愈强的效应,事实证明,它们只能通过引文级联来实现。定量分析揭示了它们发生的方式和原因。科学似乎表现得像一个自组织临界系统,其中各种大小的引文级联都会发生,从持续的科学进步到彻底改变我们看待世界的方式的科学革命。通过测量标志性论文的“促进效应”,我们的分析揭示了新思想和新参与者如何在以既定范式为主导的世界中找到出路并最终取得胜利。潜在的“促进因素”也有助于比传统的引文分析更早地发现科学突破和人才,后者现在已经成为衡量科学卓越性的一种广泛方法,影响着科学事业和研究资金的分配。我们的发现揭示了集体社会行为的模式,从注意力经济学的角度来看,这些模式也很有趣。因此,理解科学权威的起源可能最终有助于解释社会影响是如何产生的,以及为什么商品的价值如此强烈地取决于它们所吸引的注意力。
