THE CONTEXT IS REALLY IMPORTANT!
The test does not take into account your state, mood, or circumstances under which you have answered questions. Did you answer carefully or just to get through? Maybe you skipped through words or did the "let me alone" kind of job, maybe you interpreted the questions incorrectly, maybe your cat was pounding on the keyboard? None of that is considered when determining the result.
When typing, age, gender, life circumstances, psychological and physical health, upbringing, professional deformation - all are taken into account... Socionic expert learns all this, the test does not.
