Wisdom at the level of practice and wisdom at the the level of articulation are two different things. We all possess wisdom at the level of practice (well, most people in most situations); what is rare is the ability to bring this wisdom to the level of conscious thought, articulate it, and substantiate it with evidence. This is what academicians do. While common people have strategies or solutions for various situations, academicians provide rationales or explanations for those strategies/solutions. These explanations may however be of "academic" interest only, sans any practical value.
For example, in the field of business, executives or managers know what strategies to use in different situations, whereas academicians/researchers in the field of business provide explanations for those strategies. Business consultants, I think, fall somewhere in between; maybe they are closer to practitioners (executives/managers) than to academicians.
