*Subtext To Posts include "Holland's Theory: Strengthening It©" 1986 (Otherwise stated as "A Theory Of Social Change") and Q Factor Analysis Results (All eight hypotheses that could be examined by this method were supported) from The Dissertation "The Relationship Between The Myers-Briggs Type Indicator and Strong-Campbell Interest Inventory©" 1992. Both Can Be Accessed In Earliest Posts* 
The Dissertation represents one piece of research that supports the 1986 paper. For example, A. the Q-factor Analysis Summary results on pages 167-168 included: "High MBTI Intuition scores were positively associated with Investigative and Artistic and lowest on Enterprising and Conventional codes." and B. The Canonical Correlation Summary Results on page 157 included: "The results indicated that Intuition was consistently and positively associated with the A and I Holland Codes and negatively associated with the C Holland code (parentheses content omitted)  
16PF research also supports the aforementioned 1986 paper. 
Synopsis© (reminder: full text is not presented here) of Holland's Theory: Strengthening It 1986©: Presentation of Theory and Basic Assumptions  
1. The physical (including biological) universe will remain essentially the  same in its basic characteristics. 
2. Holland's Theory (1973) correctly describes individuals and the world of work at this time in our culture. (It could also be used to classify individuals of cultures in the past.)
3. Development of personality typology is probably a function of several factors. One particularly important aspect is how people gather information. 
4. A quadrilateral versus a hexagon would best delineate between typologies based on how one gathers information.

5. C and E types display a dominance/predominance of the sensation versus intuitive function. Because of their extreme degree of sensation function and hence focusing on the facts of the present they are especially vulnerable to extreme societal cultural influences.
6. Changes in society have historically occurred via a dialectical opposition of Holland types. 
7. In the future, a quadrilateral versus a hexagon will best delineate between Holland code types. 
8.The size of the quadrilateral will get smaller in the future as a more efficacious and caring social system system replaces our present social system. 
9. R types share with I types a preference for working in the physical realm while A and S types share a preference for working in the social sphere. 
10. The more an individual is a sensation type, the more likely he/she may change jobs due to an external preference (change) as the external world affects this type the most.  
11. The more an individual is a sensation type, the more (accommodating) reactive (Loftquist and Dawis, 1976) they will be and less active. 
12.Generally, the more an individual is is an intuitive type, the more (assimilating) active  (Loftquist and Dawis, 1976) they will be and less reactive.
