Is everyone of the same type alike?

From People Types and Tiger Stripes, written by Gordon Lawrence and published by CAPT.

No. There are many individual differences within each type, because many things influence personality besides type. Some people are at a higher level of type development than others. Even in people of the same type who are well developed, there are big differences. Take an ESFJ for example. You would expect all the ESFJs to share a wish for people around them to be happy and would work to achieve harmony. Some ESFJs might be interested in education and be teachers; others might become family doctors and others salespersons. Still others might find their way of helping in volunteer work or in being a good parent. All these activities offer effective ways of using Feeling in the outer world, as Extraverted Feeling types are predicted to do.
