Data, Information, Knowledge, Wisdom

I was pointed to an article by Martin Fricke (by the BCS KIDDM list) which argues that the Data-Information-Knowledge-Wisdom hierarchy is methodologically unsound. It makes for fairly heavy reading at times but has some interesting discussion about the strength of data/information/knowledge in relation to "truth":

"Information is both more extensive than data and many instances of it are logically stronger than data. Information is irreducible to data. [...] This makes knowledge and information synonymous. Knowledge and information collapse into each other"

"And the wise person must not only have wide appropriate knowledge, but they must act in accordance with the knowledge they have."

The article also mentions evidence, but in a different context to the "evidence-based practice" use - this is more related to knowledge (some discussion of whether this means "know-that" or "know-how") and wisdom.
