J. J. Thomson, the discoverer of the electron and a recipient of the Nobel Prize in physics, trained many physicists, among them seven Nobel Prize winners, 32 fellows of the Royal Society of London, and 83 professors of physics.
Conclusion
The skills needed for creative research can be taught and learned.
Evidence
J. J. Thomson, who discovered the electron and won a Nobel Prize, trained many successful physicists, including seven Nobel Prize winners, 32 fellows of the Royal Society, and 83 professors of physics.
Evaluate
There is a new concept in the conclusion, "skills needed for creative research", so we are assuming that in order for those students to achieve those accomplishments, they must have possessed the skills needed for creative research.
The argument is suggesting that because J. J. Thomson trained successful physicists, it proves that skills for creative research can be taught and learned. The burden of proof for "can be taught and learned" is super low. One data point would do it. Are we convinced that Thomson's successful students really learned from him?
In order for us to fight the conclusion, we'd have to be saying that even though they were trained by Thomson and showed themselves to be creative researchers, that's not because he taught them stuff / not because of what they learned from anyone.
Goal
Look for an answer addressing the missing link between "winning these awards" and "being a creative researcher". Or for an answer digging into whether Thomson's time with these students really involved teaching/learning that was relevant to their skills as creative researchers.
