4. Judgment/perception (in socionics: rationality / irrationality; C.G. Jung used the BOTH terms as synonyms, while Myers and Keirsey distinguish them).
The socionic criterion of rationality/irrationality, according to Jung, describes rigidity or lability of the central neural system. Rational types are rigid, judgment-focused: they strive for being consistent, systematic in their deeds, keep plans even when situation changes. By contrast, irrational people are more flexible, perception-focused: they adapt to the changing situation, and their emotional outbursts do not last too long, even when they are strong.
This descriptions was first given by Jung, accepted by Isabel Myers… and misinterpreted by her! She understood judgment as strong will, perception as weakness of character. Since such her interpretation contradicted to the original Jung's descriptions of types, she later invented a very strange model, where judgment/perception was described as something else than rationality/irrationality. Still, her model embarrasses people when they read original Jung's works! And such interpretation resulted in some bugs in her test, which we have already described above.
But let us return to socionics. Augusta completely accepted the original Jung's description of this criterion. However, initially she made another mistake. She wrongly identified this criterion with E.Kretschmer's schizothymes / cyclothymiacs. Later this hypothesis was disproved by other socionists. But still, some adepts of socionics, who read only early Augusta's work, wrongly believe that rationals are “gaunt and asthenic, with strict motions”, while irrationals are “cat-gaited, with roundish motions”.
Here are the questions from our test that correlate with rationality/irrationality.
Lability (irrationality): positive answers
13. When I practice my hobby, time ceases to exist for me. As a result, I can even forget about some important plans or promises made to other people.
64. I live in harmony with my feelings and do not like to force myself to do things which I do not like or limit myself with plans and schedules.
166. I believe that successful solutions are determined rather by freedom and spontaneity than by planning and organized actions.
253. When I fulfill any of my ideas, a different tempting idea can easily distract me, and then I can abandon my undertaking halfway.
283. Even possessing good thinking, I often lack the skill and desire to plan my work.
Rigidity (rationality): positive answers
31. I can easily plan my day so I can make all the needed contacts and visits in time.
42. I do not like to leave a work uncompleted.
91. First my work, then my rest, but never vice versa!
210. I prefer to schedule my time in advance, and for this reason, I have to now about other's people plans.
219. I am consequent in my actions.
254. I succeed in keeping my affairs in order, and I am allergic to any chaos or unsystematic actions.
261. I am a person of obligations (before my family, friends, and work).
275. When my work is more or less complicated, I first plan it, and then methodically follow my plan.
291. I never give worthless promises and do not respect people who make them too easily.
