We hear much of voodoo science or junk science or even scientific science, in this paper I seek to evaluate and understand how we might approach a description of the qualities of science. In this I base my reasoning on the equivalence of the words science and knowledge. I then note that the application of the scientific method determines how confident we may be in what we hold as knowledge or science (basically a tested guess or hypothesis). The different levels (...) of confidence are reflected in a variety of terms, including: good or bad, junk or valuable, voodoo or reliable. (shrink)
