Do you honestly think string theory was useful for something? As to experiments I am not suggesting they are the only form of evidence. Finding a new fossil can easily count as evidence in support of a different theory.

Still, coming up with a new theory and suggesting an experiment is IMO far more useful than simply another theory. The point is to avoid doing this: The real name of god is A, no it's AA, no it's AAA...

I might not be explaning this all that well. There is a somewhat recent theory that a lot of exising dinosaur species where not distinct. Rather there bone structures change as they age. In many ways you could argue this is just evaluating evidence differently. However, rather than simply standing alone it suggested examining a range of existing fossils in ways that also supported this theory. Which was then done. The important bit IMO was not stopping at the theory stage.
