New analysis of SciSciNet data covering more than 206,000 scientists over four decades shows that while senior researchers produce disruptive work less often, their disruptive ideas tend to endure and be built upon in later research.

As scientists' careers progress, the likelihood of producing a disruptive paper declines, but the likelihood of achieving persistent disruption—ideas that persist and are consolidated by later work—increases.

Across a large publication record, the trend is clear: senior researchers generate disruptive work less frequently than juniors, yet their disruptive contributions tend to have lasting influence.

The authors warn that current evaluation and funding systems that prize immediate disruption may overlook the enduring value of durable disruptive ideas and the role of experience in their development and spread.

To measure lasting impact, researchers created a persistent disruption index, distinguishing disruption that endures (top 5% for reference disruption) from disruption that fades (bottom 5% for citation disruption).
