Step-by-step explanation:
The only requirement is a commitment to science and reason, to evidence, and the quest for truth. By using control, you have something to compare with the experimental treatment. A skeptical scientist does not believe everything he or she is told. By being skeptical about established ideas, a scientist is open to new ones. Scientific Skeptics attempt to evaluate claims based on verifiability and falsifiability; they discouraged accepting claims which rely on faith or an anecdotal. Skeptics often focused their criticism on claims they consider implausible, dubious or clearly contradictory to generally - accepted science. Scientists also use a method called peer review. When they complete papers, presenting new ideas and evidence, those papers have to be read and critiqued by other scientists before they can be published. This weeds out a lot of bad quality research and builds on consensus in the community. Putting Science Into Practice
Most scientists are convinced of new and changing ideas if enough evidence is provided because science is based around evidence, and so that's what scientists respond to best.
