On another note, using the graph you'll be able to further move ahead by placing the correct men within an organisation or within the power structure of a society.
An example, if I were to say hire a group of 10 country sales managers for the entire South East Asia and want to truly maximise profits, I'll hire 1 motivator, 1 intellectual, 2 expressive's and 6 doers.
The motivator is predisposed to have grandeur plans of expansion and will convince the entire sales group, once that's in motion the intellectuals will come up with minute plans on how it's done, whilst the doers will efficiently execute it, and all the while the expressive's will keep the group cohesion intact by entertainment, some drama...etc.
No one group of the quadrant is more important then the other.
They are all equally important for things to work.
Perhaps some of you would more predisposed to understand this if I were to use personalities in a TV series.
The Walking Dead - Rick Grimes and Negan both play the roles of motivator yet with opposing structure.
In it, try to use the graph to properly place different characters within it.
Who are the doers?
Who are the expressives?
Who are the intellectuals?
