TL;DR
New ideas and their proponents face the challenge of competing with established scientists who benefit from rich-gets-richer citation dynamics. The paper analyzes citation rates around landmark papers and finds that they boost citations to earlier work, with peak sizes suggesting citation cascades.
Problem
How new ideas and lesser-known scientists can gain authority despite established scientists' rich-gets-richer advantage remains a puzzle.

Abstract
from arXiv · showhide
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.
I. INTRODUCTION
Groundbreaking papers can transform scientific practice, but how new ideas and their proponents succeed against the accumulated advantage of established scientists remains a puzzle. The paper investigates whether landmark discoveries increase the impact of their authors’ earlier work.
I. INTRODUCTION
- Groundbreaking papers can transform research subjects, methods, and presentation, yet only a few ideas gain attention across the world and disciplinary boundaries.The spreading of ideas has been described as epidemic percolation in a social network.Source: §I · p. 1
- New ideas and their proponents must overcome rich-gets-richer dynamics, in which famous scientists may receive disproportionate credit and established work commands great authority.The paper frames how a previously unknown scientist can establish reputation under these conditions as an unresolved puzzle.Source: §I · p. 1
- Results for 124 Nobel laureates suggest that a landmark paper can increase the impact of its author's body of work by drawing attention to earlier publications.The paper describes this as future papers causing past papers to be newly weighted in relevance.Source: §I · p. 1
- The study uses citations as an indicator of scientific impact, drawing on ISI Web of Science data; citations also inform rankings, recruitment, and research funding.The authors note that click streams could also be used.Source: §I · p. 1
II. RESULTS
Across Nobel laureates and other established experts, landmark papers coincide with citation-rate peaks for earlier work. The peaks persist when the landmark paper is excluded, supporting a collective boost; their size distribution suggests citation cascades.
II. RESULTS
- Across 124 Nobel laureates and about 2 million citations, rate-change peaks also appear for internationally established experts, and linked landmark papers can reach hundreds of citations over a decade.Some authors have several such peaks.Source: §II · p. 1
- The boost factor is the post-window citation rate divided by the pre-window rate for the same author papers, highlighting sudden increases as time-series peaks.The two rates average citations per paper per year over windows before and after year t.Source: §II · p. 2
- Boost-factor peaks persist, though smaller, when the landmark paper is excluded, indicating that boosts reflect increased citation rates across multiple earlier publications.The authors link this collective effect to greater visibility for the scientist’s body of work; boosted older papers are not always related to the landmark’s topic.Source: §II · p. 2, Figure 2 · p. 2
- Classical indices have relatively smooth profiles and are less sensitive to landmark events, whereas boost-factor peaks can identify breakthroughs earlier.The comparison includes average citations per paper, cumulative citations, and the h-index.Source: §II · pp. 2–3
- Peak-height distributions resemble power laws across parameter choices, suggesting citation cascades, although the left-plot data span only one decade.The authors caution that the limited range makes power-law evidence uncertain for those plots.Source: §II · p. 3, Figure 5 · p. 4
- A cluster analysis separates laureates and a random scientist sample in proportions of 79% to 21%, but the groups overlap partly because of exceptional random picks and field-specific citation frequencies.The authors suggest that additional dimensions could improve separation and that the boost factor can be combined with other measures.Source: §II · pp. 3–4
III. DISCUSSION
Landmark papers can boost their authors’ earlier publications, bringing the broader body of work to attention and establishing authority. The findings connect these citation boosts to cascades spanning routine progress through scientific revolutions, while noting that citation measures alone do not determine Nobel recognition.
III. DISCUSSION
- Landmark papers boost authors’ earlier publications, bringing their broader body of work to attention and establishing scientific authority.The paper presents the boost factor as a quantitative measure sensitive to sudden citation-rate changes.Source: §III · p. 4
- Nobel laureates perform better on average in citations and boost factor, but these measures alone do not determine Nobel recognition.Innovation and quality may also matter, though they are hard to quantify.Source: Figure 6 · p. 4
- The boost factor may reveal breakthroughs and talents sooner than classical citation indices.The paper also suggests it may help assemble research teams.Source: §III · p. 4
- Power-law peak sizes suggest citation avalanches span quasi-continuous progress through scientific revolutions that change perceptions of the world.The paper interprets this pattern as evidence for phase transitions.Source: §III · p. 4
- The study may also shed light on feedback effects linking attention to social influence and the value of companies or products.The authors note that these related phenomena remain incompletely understood.Source: §III · pp. 4–5
IV. MATERIALS AND METHODS
The method aims to detect sudden changes in citation rates while reducing noise. It weights highly cited papers more heavily and introduces a formula for the boost factor.

- The method seeks to improve the citation-rate signal-to-noise ratio to detect sudden changes.It reduces the influence of papers with highly fluctuating citation rates.Source: §IV · p. 5
- Raising citation counts to a power k greater than 1 weights highly cited papers more heavily.The stated purpose is to reduce the influence of papers with largely fluctuating citation rates.Source: §IV · p. 5
- The method introduces a formula for R′_w(t), with the sum over p including the author’s papers published up to year t.Here, c_p,t′ denotes the citations received by paper p in year t′.Source: §IV · p. 5
