Edited: is this type related and is this devalued Fe/
I've found this attitude common in the town I'm in...and it seems to me to be a Gamma thing. It's connected with a non-chalant way of doing things .The people are cold and do not register body language and facial expression and do not give off much of their own ...and yes it makes me uncomfortable. This atmosphere pervades an entire section and subculture in the college town I live in.
Gammas in general seem to naturally give it off and it matches somewhat with the overall mood of ILI's and other gammas. It also matches very well with the description of SLI, but I have little expirience with them.
The overall mood coincides with the "hipster" culture found here, not all of course but as the integral mood. Hipster in this case is more loosely defined as a subculture found in the town.
Personally I find the attitude stupid, trite, and unnaturally cold and closeminded.(in my interelations with these people)
"goofy; don't reveal their inner life; interested in processes; passive relaxedness; ironic attitude "
soft blankness; internal independence; hard to impress; not easily excited; emotionally cool
I would add that the overall moods posted on the site do not actualy convey the mood, they convey an mindset attitude and that type descriptions from each type (or at least the Fi/Fe divide or quadra) might be much easier to get for recognition. Perhaps I'll try and work on that.
