One is in the womb with all needs given to the being inside of the womb. When born the concept of obtaining your own needs becomes terrifyingly apparent, and the concept of good and bad is formed in the beings psyche. So unless this idea is only a facade of the real truth, then this concept is undeniably truth, and logically sound. From this concept of good and bad comes the concept of thought within the brain.
This thought develops into personalities one is drawn into different ideas of how to escape bad, and come closer to good. This reaches to such complication, that one can not see into the beginning, but only sees a facade of "self". So the psychology behind personality and decision becomes apparent unless again, this is only a facade of something more complicated, or possibly more simple.
Now lets look at the psychology of a being who was never born, and has no needs. This being would be the same as one who is in the womb. This is because one in the womb has all its needs taken care of, but has no concept of the needs actually existing, therefore the needs conceptually don't exist. This means that one who has no needs, has no consciousness, has no point of focus to make a decision.
