Abstract
The study aimed to empirically prove sixteen psychological types based
on the theory of C. G. Jung and the work of K. C. Briggs and I. Briggs
Myers. A thousand one hundred and fifty-three adults aged from 18 to 69
completed the Golden Profiler of Personality (GPOP) questionnaire. The
differences between percentiles rank score in the opposition preferences
of the global dimensions (extroverted (E) / introverting (I), sensing
(S) / intuition (N), thinking (T) / feeling (F), judging (J) /
perceiving (P)) entered K-means cluster analysis. The results of the
analysis empirically confirmed the existence of sixteen psychological
types. They differed in the raw score of all preferences significantly
with a large effect size. 37% of the research sample did not enter the
cluster analyses due to the small difference between the opposite
preferences. Not all participants had their preferences differentiated
enough to be a type; the discussion dealt with conditions of empirical
confirmation of psychological types.
