I finally got time to read this study
https://www.nature.com/articles/s41586-022-05543-x Shows that the fraction of disruptive science has declined since the mid 20th century . One explanation is changes in the incentives for research, benifiting incremental science and digging deeper within safe areas of expertice rather than exploring new knowledge combinations. I wonder how these results go with research that show that big collaborations, also inter-disciplnary, tend to be more incremental.
