Answers.Text: It seems that wisdom in the sense of experience is only relevant in that it may contribute to making good decisions. The idea of complete information got me thinking about game AI, where wisdom could be defined as the ability to make optimal plays, even under conditions of incomplete information, chance, an/or mathematical or computational intractability.  Game AI would seem to be "wise" enough to beat the strongest human players without the need for qualia or consciousness...

Answers.Text: Exactly. Data is data. Who, when, where, how _and_ why are all what-data. Why includes subjective preferences and goals. The non-why, ontological portion of the what-data approximates an objective representation of the external and internal world. Despite this, the particular encoding of that objective data is still highly subjective, driven by teleological forces. DNA has a highly subjective representation of its "factual" knowledge of the world. Humans are good at removing teleological, subjective bias from our ontological, factual knowledge. Wisdom is a subset of what-data, whatever it is.

ThreadText: # How would "wisdom" be defined in AI?
  
  (Asked by: username_0 on 2016-10-01)
  
  For years, I have been dealing with (and teaching) Knowledge Representation and Knowledge Representation languages. I just discovered that in another community (Information Systems and the such) there is something called the "DIKW pyramid" where they add another step after knowledge, namely wisdom.
  They define data as being simply symbols, information as being the answer to who/what/when/where?, knowledge as being the answer to how?, and wisdom as being the answer to why?.
  
  My question is: has anyone done the connection between what AI calls data/information/knowledge and these notions from Information Systems? In particular, how would "wisdom" be defined in AI? And since we have KR languages, how would we represent "wisdom" as they define it?
  
  Any references would be welcome.

  It could be argued that defining 'cause' in terms of distributions rather than specific concrete mechanisms is a rather limited notion of 'Why?'.
  
  However, it may be that there are some forms of causality that we don't know how to represent, specifically 'first-hand experience'. Indeed, common usage of the term 'wisdom' generally refers to first-hand experience, rather than information gained from some other source.
