Secondary extraverted logic
(the types Critic and Craftsman, XXX-logical introverts)
They may be misperceived for the quasi-identical types (Analyst and Inspector with the dominant introverted logic) for their calm logical emotionless manner of explaining their views, and for certain vital conservatism. However, the difference is, that they do not strive for being consistent and systematic in their thoughts
– on the contrary, they strive for adaptation to ever-changing situation, and thus their sayings often look incomplete or vague.
Carl Gustav Jung, although some typologists think he was an Analyst, not Critic, wrote in a very vague, ambiguous way, often left his ideas uncompleted, and even his typology was for him just a “by-product”.
