The Lenore Thomson Exegesis Wiki
An answer to "Jung Explained?" in Louis Farrakhan
Keirsey is somewhat flawed (at least when attempting a direct correlation with Jung -- the types hit both main types and sub-types and other types). Myers-Briggs Te descriptions do not in any way forbid Cuvier from being a scientist (he was for most of his life). Even moreso, his entire life focus was on a particular science (and one aspect of that science - ESTJ). Ne/Se tends to cause people to spread out to divergent opportunities (and do those in depth, as opposed to the light analysis of one person's book on this wiki -- This wiki is analyzing one person's book from multiple angles of active human perception (instead of figuring out what perception is and how it is allowed - Ti). Ne would start with a possibility and inductively/randomly add to it (South Park, Bruce Lee).
(The introverted types tend toward fleshing out -- Ni/Si via ways similar to this wiki, Ti/Fi via checking for coherence to reality and internal cohesiveness.
Cause and effect. Because of this aspect of this animal bone, the animal itself must have been this way. Introverted thinking is filled with retractions, clauses (ie. "except in this case"%), etc.... Extroverted thinking is not. My dad is an ETJ (think Terry Pratchett, Bill Nye the Science Guy, MacGyver, Julian Barbour, Michael Medved Te vs. Peter Lynds, Xeno, Nietzsche Ti), I recognize the difference.
% - As opposed to introverted perception which is filled with parentheticals defining what it is the person is talking about (wikis). -- An example of definition through reference to an opposite/counter.
From an introverted judging perspective, the only value in Keirsey is his categories and descriptions of communication and orientation. Trying to collate his types to Jung's base types is difficult (he lists Camille Paglia, an ESTJ, as an ENTP -- and seems to base at least part (this is an example of Ti clause usage) of his description of ENTP on what Jung would have called ESTJ).
