You're correct in the sense that this is what science is per Popperian definition. However, I would be careful to assume that many scientists are actually so busy refuting hypotheses. The Popperian ideal and the reality in science are two different things.

To cite a paper I currently read:

> "As Chalmers (1999) remarks, when we turn to history of science, the idea that falsificationism is actively undertaken borders on laughable (see especially Feyerabend, 1975). Not only do scientists exhibit extreme reluctance to falsify their work (Woodward and Goodstein, 1996), but if falsification had been followed as a scientific method, then many of the theories generated by some of the best minds in science would never have progressed beyond their earliest explications (see Chalmers, 1999: ch. 7; Feyerabend, 1975; Kuhn, 1970c: 234; 1970d: 13; Von Dietz, 2001: 22)."

I haven't read all the sources. But it's worth mentioning that your point is controversial.
