Let me answer your first question with another question: if you understand that we only have conscious use of our top four functions, why would being in a group of INTPs make us use more cognitive functions than we have conscious control over?Adymus. I want to post this before I forget it:
It it true that CF100 is about individuals? It is about cognitive processes of individuals? Although it touches on how we might behave with others, it doesn't focus on group behavior.
Here is a thought experiment: Put 16 INTPs in a room. Give them a theme or not, but let them interact. Since all people are different, do you believe some INTPs will be inclined to exhibit cognitive functions of the other 15 types?
Just to continue the thought, suppose there is a theme or project. Some will remain passive (perception); some will grow active (judgment/choosing). Some will become frustrated or upset (feeling); some will be motivated toward leadership. Anything could happen. Now if so, do we know enough to say at least for the duration of this INTP group experiment, the ordinary Ti-Ne-Si-Fe will break up? Or in what sense would it break up?
Would or could we see the emergence of INFP or even ESFJ behavior which would revert to standard INTP when the group disperses?
If this question belongs to CF200, then we will have to wait for it. I just thought I'd ask.
I think you maybe worded your question wrong, did you mean to ask: Since all people are different, do you believe some INTPs will be inclined to exhibit Behavior of the other 15 types?
Sure, I suppose this is somewhat accurate to say. People have developed differently throughout their lives, some have better control over lower functions, some have poor development in Ne, some let their Ti and Ne move freely without modulating it often with Si and Fe, etc etc etc.
Now then, this not exuding behavior of the cognitive functions of other types, because it is still Ti-Ne-Si-Fe and in that order, but if you are asking if they might have a look and feel that is similar to some other types (when compared to the other INTPs), then yes this is true.
INTPs that are developed in certain ways will fit into certain niches where others may not be as comfortable fitting into. For instance if an INTP is more comfortable with their Directive functions, they might take the role of leader, or director of other INTPs. One that is more comfortable with their Fe might also take the facilitator role, etc.
So yes, you will see differences in behavior and roles that they take, but it is still all INTP behavior, because you niche and role is not necessarily defined by your Personality type, that is why we have the versatility of our lower functions.
