One acceptable definition:

"Norman Cousins gives a definition of the scientific method that not only describes it but also shows its value: “The most important thing about science is the scientific method—a way of thinking systematically, a way of assembling evidence and appraising it, a way of conducting experiments so as to predict accurately what will happen under given circumstances, a way of ascertaining and recognizing one’s own errors, a way of finding the fallacies of long-held ideas. Science itself is constantly changing, largely as a result of the scientific method.”
