> If we were really nitpicky about falsification, we would completely cease doing/studying/researching psychology, economics and a whole host of complex topics. That's totally false. Don't lump in other sciences with whatever physics is doing with string theory just because you don't have experience with them. Psychology and economics are ruled by falsifiable theories! You might not be able to run experiments that are as clean as one might want, but our theories of how, for example, children learn language are absolutely falsifiable and they make concrete predictions about the kinds of errors children should make. Or what kind of behavior you should see from your dog when you train them, theories built up with hard work over a century of modeling and experiments.
