I do personality analysis for some of my church members using TJTA and the PFP (which is a combination of DISC and MBTI). One of the advantage of TJTA is that it is cheaper since we process the information ourselves and hence we also do cross-analysis (you analyse yourself and your partner also analyse you). For some people, this can lead to a very interesting result. The person can be scored high on a temperament but be scored low by his partner or vice versa. Why is this so? It is usually either of 2 reasons:
a. There is a problem in communication. The person may think he is like this, but the image received by others is that he is really like that. Like all problems in communication, it could be a problem with the communicator or the receiver or both.
b. The person chooses to behave very differently for different situations or towards different groups of people.
Though reason b is somewhat understandable, I don't think that it is what is best for a person's mental health. It is tough to play two roles in life, and it is even scarier is one of the role is only an act but not really owned. I'll advice, "Choose what you like to be and truly be yourself."
This poem quoted by Eugene Peterson from Gerard Manley Hopkins is truly very beautiful and true. An online analysis.
As kingfishers catch fire, dragonflies dráw fláme;
As tumbled over rim in roundy wells
Stones ring; like each tucked string tells, each hung bell's
Bow swung finds tongue to fling out broad its name;
Each mortal thing does one thing and the same:
Deals out that being indoors each one dwells;
Selves - goes itself; myself it speak and spells,
Crying Whát I do is me: for that I came.
Í say móre: the just man justices;
Kéeps grace: thát keeps all his goings graces;
Acts in God's eye what in God's eye he is -
Chríst - for Christ play in ten thousand places,
Lovely in limbs, and lovely in eyes not his
To the Father through the features of men's faces.
