This is to be contrasted to non-empirical methods, even those that are formulated by observation. For a theory to be scientifically valid, it must be testable. In either case, however, this process must aim at the production of new, falsifiable predictions. Despite the criticism of Karl Popper's falsifiability theory for the demarcation between science and non-science, mainly pseudo-science, this criterion is still very useful, and perfectly valid after it was perfected by Popper and his followers. 22 Falsifiability is a desideratum for any scientific theory: very roughly, a theory should be such that it is in principle falsifiable.
