Is the supernatural/paranormal subject to the scientific method?

For those of you that believe in the supernatural and/or paranormal, can we use the scientific method to categorise, understand and measure these phenomena? If a particular action coexists with a paranormal experience, will that action and the experience be able to be expressed as a causal link?

Following from this, is it possible that the supernatural will one day be able to be manipulated on such a scale that it is considered ‘natural’ rather than ‘supernatural’?
