- A disruptive paper is defined here by the likelihood that this paper (and not the references inside it) will be cited by subsequent studies.
- In contrast, a consolidating paper is the one that is less likely to be cited than its predecessors. It consolidates the discovery.
Importantly, when only articles published in Nature, PNAS and Science or to Nobel-winning discoveries are considered, the downward trend STILL persists.
What explanation do authors suggest for the drop of disruptiveness?
Let’s check their original study: 1. It is NOT that we have less ‘low-hanging fruits’ in science 2. Nor is it the diminishing quality of science and technology. 3. It's not due to used datasets. 4. Also, it is NOT due to changing publication, citation or authorship practices.
So, what is it then?
It's due to our reliance on a narrower scientific knowledge. In the study, the authors see (1) a decline in the use of previous knowledge, (2) increase in self-citation & continuation of pre-existing research, (3) the mean age of work cited is increasing.
So, the growth in publishing (quantity of papers) leads to narrower research. Scientists have just got stuck in their own narrow subfields!! They cannot keep up with the pace of knowledge expansion and instead rely on older and familiar work.
This is WHY I am so much advocating for: 1. Getting out of your comfort research area and searching for new areas. Outside of your field. 2. Creating new interfaces between scientifically distinct areas! This is SO MUCH important if one wants to make a discovery.
This is WHY at my Electrochemical Online Colloquium (@EChemColloquium) I invite a lot of speakers who do NOT work in electrochemistry directly. This is the only way to efficiently learn about the research in other fields and seek new prospects for your own.
Throughout my “career”, I have encountered tons of resistance from scientists. At faculty interviews, in grant proposals and everyday “scientific” life. Everyone defends the status quo.
Few places seek scientists who want to do new things.
It is enormously disappointing. 😢

They will just make everyone unhappier:
- Your team members will feel burned out and depressed
- Journal editors will feel like there’s another manuscript that no one is willing to review
- The poor reviewers will feel like they have to review a manuscript they don’t care about
- More researchers will feel like they don’t want to get updated about so many papers from your group, especially when their quality gets worse
Advice for #PhD students who want to become postdocs and stay in #academia:
- How to choose a lab for a postdoc
- How to prepare for an interview
- What to be careful about
1. Decide on how far you want to move away from your PhD topic. Keep in mind:
- If your #postdoc research is distant, you will need more time to gain expertise and do competitive work
- Diverse and strong(!) expertise can make you stand out during faculty interviews and help you establish unique research directions
- BUT: gaining a bit of expertise here and there will hardly give you any advantage in the end
PhD students don’t want to be postdocs. Faculties are leaving academia... Intriguing discussions are published by both Nature and Science.
Key points are:
1. U.S.-based researchers reported challenges recruiting in all #STEM fields: “This year … we received absolutely zero response from our posting,” one wrote. “The number of applications is 10 times less than 2018-2019,” another wrote.
2. Faculty: “It took 2 months to receive a single application [for a postdoc position]. Money is just sitting there that isn’t being used … and there’s these projects that aren’t moving anywhere as a result”.
