Aresearcher confirmed her hypothesis by obtaining data through a scientific study. she published her work and results, while proudly stating she had developed a new theory. how would other scientists most likely react to this claim?

I think most scientists would not respect this researchers claim.
It doesn't seem like the researcher followed the steps of the scientific method.
1.) Making an observation.
2.)Asking questions.
3.)Forming a hypothesis.
4.)Conducting an experiment.
5.)Analyzing Data.
6.)Drawing a conclusion.
7.)Showing work to others.

Publishing his/her work would be the very last step after completing everything else.
