Hi there.. Thanks or the responses so far!
I haven't taken any statistical data, yet, but what I notice is that there is a strong relationship pattern between:
INFJ's being "Social"/"Conventional"
ENFPs somewhere along the lines of "Social/Enterprising/Artistic"
INFPs either Realistic/Investigative/Artistic or Social/Investigative/Artistic.
I'm thinking those who fall within the RCE are strongly "sensors" who have a bit of "J" in them.
Based on a class I took called Clinical Counseling Theories, my instructor says that the Holland Code test is more accurate/reliable compared to the MBTI, in terms of finding occupations. She vehemently despises MBTI. According to her: it's not peer-reviewed, scientifically valid, and the scaling system is too flawed.. In her own words, "They are ONLY offered at community colleges/universities because they are cheaper to give as career aptitude tests." Anyway, I still think it's interesting how well the MBTI scores relate to Holland Codes. =)
Based on the Holland Code theory, most people score highest in 2 to 3 areas (sometimes more). The ideal career match for a person would align their Holland codes with at least the first 2 codes of each profession. For instance, people who have a strong interest in SIA would be ideally matched with careers that offer lots of interaction (Social), down time for research (Investigative), and creative approaches to teaching styles/class projects (Artistic). These people highly suit the academic setting (colleges/universities).
The top three scores, according to this theory, should also touch each one another along this chart (in other words- rarely do the codes not touch):
Please note, it's uncommon that a person has opposing codes (I.e. "Conventional/Artistic"- since artistic interests usually don't match with conventional ideals or "Social/Realistic"- realistic being hands on, working with machines, not much with people, social- high interest in interpersonal relationships). It's not to say that it can't/doesn't exist, but not as often (from what I read). For those who are strong in more than 3 codes, it's more likely due to experiences in the work force (nothing wrong with being 'well-rounded,' right?). Ideally, if one cannot find work that matches all 3 codes, it's advisable to balance the unmatched ones with hobbies that reflect those interests. Sorry, this is my quick/dirty explanation.
For those who are want to learn more about these Codes for Career Exploration:
