This is obviously a matter of deep and extensive philosophical debate, and I'll admit my definition isn't perfect, but to address your comment: > And most advice that you encounter will work for some people but not others. Does that make whether or not it is science depend on the audience? The question is whether or not it works in aggregate, i.e. for most people to whom the advice could apply. If it doesn't, then we would say it's not scientifically sound advice. > science is a particular process and methodology supported by a set of norms that enable us to continue building a fact based picture of reality. Science is not one process or methodology; there is the scientific method, but not all science uses it. For example, paleontologists cannot form an experiment to test a hypothesis of what killed the dinosaurs. But science can still give us a fairly accurate picture of what probably killed them.
