There’s no shortage of theories to explain personality types and models. Common among them, of course, is the Briggs Meyers (or is Meyers Briggs?). It seems to be the theory of choice in many corporate-wide organizations. Rooted in Carl Jung’s theory, it’s a straight-forward theory allowing for classification for working in teams, understanding strengths and weaknesses, as well as developing an understanding of other’s motivations and behavior. I would imagine many people could recite their own classification: Me=ESFJ, my husband= ISFJ.
With David Kolb’s Learning Style Model, I see myself : CE/AE What I like about this model is its two layered approach. The outer circle Concrete, Reflective, Abstract and Active while the inner circle is Diverging, Assimilating, Converging and Accommodating. So, while it’s easy to classify oneself into a category, it’s interesting to see that it can be fluid. Sometimes I am active; other times accommodating. Sometimes assimilating. I’m sure others weave between the categories.
Everywhere I turn there seems to be some test that will classify you. Last year, I participated in a DISC training (http://en.wikipedia.org/wiki/DISC_assessment). I guess I found it interesting but hesitate to put all my eggs in a basket. Differences in personalities and mindsets seem limitless.
