Initial Burst of Disruptive Efforts over Individual Scientific Careers

Despite persistent efforts to understand the dynamics of creativity of scientists over careers in terms of productivity, impact, and prize, little is known about the dynamics of scientists' disruptive efforts that affect individual academic careers and drive scientific advance. Drawing on millions of data over six decades and across nineteen disciplines, associating the publication records of individual scientists with the disruption index, we systematically quantify the temporal pattern of disruptive ideas over individual scientific careers, providing a detailed understanding of the macro phenomenon of scientific stagnation from the individual perspective. We start by checking the relationship between disruption-based and citation-based publication profiles. Next, we observe the finite inequality in the disruptive productivity of scientists, diminishing gradually as the level of disruption increases. We then identify the initial burst phenomenon in disruption dynamics. It is further revealed that while early engagement in high disruption frictions away initial productivity, compared to initial advantage in productivity or impact, initial high disruption ensures more subsequent academic viability evidenced by a longer career span and relatively final higher productivity, but does not necessarily guarantee academic success throughout careers. Further analysis shows that increasing disruptive work is uncorrelated to overall productivity but negatively correlated with the overall impact. However, increasing disruptive work in the early career is associated with higher overall productivity, yet lower overall productivity in the later career. Our research underscores the urgent need for a policy shift that encourages a balance between the pursuit of disruptive efforts and the achievement of impactful outcomes.
