People are forced through society, culture and family to try to fit into the mold of Stage II. However, through genetic make-up/nature, exposure, experience many in stage II actually have stage I, III, or IV mindsets. It is possible for a person to have a mindset that is a combination of stages (generally not the case).
While remaining within stage II, a person, out of fear (fear of "God," family, group, etc.) will not allow (or cannot allow) themselves or others to see their true mindset. If we use JWs as our stage II model, we can peer in and locate various aspects of the other stages within certain individuals.
Stage I JW-This person is a JW for his own selfish reasons. Maybe to keep a mate, shut his/her parents up...basically 'serving time' until he/she can be themselves. They never actually conform to JWism, but live a "double life" They do their own thing, may not get baptized, give talks, answer or go in services. They don't conform and are considered weak spiritually and 'worldly.' These people generally go off to do their own thing when they no longer have to remain a JW.
Stage III JW-This person by birth or circumstance finds him/herself within the confines of JWism. A natural skeptic, he/she is never truly convinced. Because of their analytical nature and intelligence, they generally move up the JW hierarchy with ease. They are research hounds. They may present different ways of looking at a belief to others making sure they never go beyond the groups consensus while they are within stage II. If a person with a stage III mindset feeds his/her hunger for alternative ways to view things...he/she will not remain a JW. But, gradually moves on in an effort to satisfy his/her insatiable appetite for knowledge, reason and information.
Stage IV JW-This is usually the "loving elder" that everyone wants to have visit when they do something wrong. He is kind, understanding, forgiving, open and nonjudgmental. Although while remaining in stage II he still has to submit to the rules of the Organization...he is moved by his heart, empathy, and love of humanity. He is the least likely to disfellowship someone for breaking a stage II rule. A person with stage IV mindset is considered to be an "open minded" JW. He/she does not truly believe that JWs are the only one who will be saved during Armageddon. But, that God's love will encompass all groups of humanity and believes "God reads our hearts...He alone is the Judge" If this elder continues to feed his natural stage IV mindset...he will slowly become isolated from the other elders. He no doubt will leave JWism because of a serious injustice committed on the part of the other elders or the Society in general towards an innocent person or group.
The predominate qualities that stand out for me in each stage as outlined are:
I-selfishness
II-fear
II-cynicism
III-love
