Result: oppurtunity minded
Process: obstacle minded
Result and Process determine how Positivism and Negativism are distributed along Static and Dynamic blocks in the model A. As such there are quite a few characteristics related to the colloquial optimism/pessimism "dichotomy" that are to be attributed to Result/Process rather than Positivism/Negativism.
NB: this does not mean that everything with regard to optimism/pessimism has been said and done once Process/Result has been linked to it. Merry/Serious is also almost certainly related, Serious being the more pessimistic.
Negative/Process: the attitude of a person that is gathering information on obstacles on his/her path (I need to do this, that, take care of that, all the while preventing this... etc)
Positive/Result: the attitude of a person that is scouting out oppurtunities in his surroundings
Those cover the Dynamic types: people with thoughts that are not clearly divorced from the environment; people who think along with the environment.
The Statics think apart from the environment and are more likely at variance with it. Their attitude towards problems is also contrasted to what the environment offers.
Positive/Process: the environment provides problems and the person ranges over ways to solve these. The focus is on reaching a breakthrough.
Negative/Result: the environment provides oppurtunities and the person formulates a personal problem in light of these; how does one best make use of these oppurtunities in limited time?
