Hello, @Sandra, your data seems supported for the Meyers-Briggs personality types, that the INFJ is the least common. Though I believe this article was pertaining to the Enneagram only. The Enneagram seems to lack the scientific rigor supporting other personality assessments & types but does seem to have functional usefulness in my personal opinion. (Fellow INFJ, & EIP 8 w/ 4 wing).
