Kuhn: Structure of Scientific Revolutions

Phase 1- Pre-paradigm phase Phase 2- Normal science Phase 3- Crisis Phase 4- Paradigm shift Phase 5- Post-Revolution

7/48

Phase 1 – Pre-paradigm

Phase 1- It exists only once and is the pre-paradigm phase, in which there is no c o n s e n s u s o n a n y particular theory, though the research being carried out can be considered scientific in nature.

8/48

Normal Science begins, in which puzzles are solved within the context of the dominant paradigm. As long as there is consensus within the discipline, normal science continues. Over time, progress in normal s c i e n c e m a y r e v e a l anomalies.

Phase 2 – Normal science

9/48

Gatekeeping (peer-review) Dear Sir, We (Mr. Rosen and I) had sent you our manuscript for publication and had not authorized you to show it to specialists before it is printed. I see no reason to address the — in any case erroneous — comments of your anonymous expert. On the basis of this incident I prefer to publish the paper elsewhere. Respectfully,

Albert Einstein, 1936

Academic Publishers

12/48

Open-access

CON: Vanity journals will publish low-quality science to boost CVs and egos

PRO: Better access Faster Cheaper for libraries

Copyright: You can start reading open-access journals, but you can't stop reading the closed ones.

Phase 3 – Crisis

Crises are often resolved within the context of normal science. However, after significant efforts of normal science within a paradigm fail, science may enter the next phase.

“Today I wouldn't get an academic job. It's as simple as that. I don't think I would be regarded as productive enough.”

Peter Higgs, 2014

The Crisis

15/48

Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true.

The Crisis

17/48

Phase 4 – Paradigm shift

Scientific revolution is the phase in which the underlying assumptions o f t h e f i e l d a r e reexamined and a new paradigm is established.

Phase 5 – Post-revolution Post-Revolution, the new paradigm's dominance is e s t a b l i s h e d a n d s o scientists return to normal science, solving puzzles within the new paradigm.

43/48

Open science

44/48

Why do this

•  Engagement/discussion forum

•  Connects researchers

•  Brings the science closer to the researchers/public

•  Adds value to papers

•  Makes scientists read about more papers

•  Develops grant writing and communication skills

•  Reduces noise in science communication
