a scientist discovers an important breakthrough in cancer treatment. The scientist thinks the information could save thousands of lives and immediately announces the results on national television, skipping peer review. How might other scientists react to this news?

They will be skeptical because the report was not peer-reviewed.***
They will quickly start to use the new treatment on their patients.
They will congratulate the scientist for the discovery.
They will denounce the work and call the scientist a fraud.

*** I think that it is this one. Am I correct?
