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.
The participants agreed with anonymous and group data analysis for the research study purpose. To strengthen the motivation to fill in the questionnaire, the participants received the feedback report with the results. The research was aligned with the Ethical Code of Pan-European University No. 1 / 2018.
