Figure 1

Total number of collaborators and publications for prominent researchers. (A)-(H) Logarithm of the total number of collaborators as a function of the logarithm of the total number of publications for each prominent researcher in: (A) inequalities in health, (B) network science, (C) metabolomics, , (D) network ecology, (E) development economics, (F) philosphy of science, (G) genetics and (H) cognitive psycology. Red circles and blue triangles correspond to prominent researchers based in North America and Europe, respectively. We test whether the points are distributed differently using the 2D Kolmogorov-Smirnov statistic [28], and calculate the significance by resampling the researchers’ affiliations. At the 5% confidence level, we can only reject the null hypothesis (that both subsets are drawn from the same distribution) in the case of network ecology
