I thought it would be a good idea to explores the ways in which introverts who are also Feelers are similar and face similar things in society.
I would suggest that negotiating society can be the most difficult for this combined demographic, even though the Sensing types are more prevalent. There is a way in which each of these type s can experience a lot of social pressure to conform to the requirements of the more forceful types. For the INFP/INFJs, this can be combined with feelings of being misunderstood by society, but for the ISFP/ISFJ could it actually be worse to be better understood and still face pressure to conform to being a more dominant type?
I think that in work environments and in personal, social environments, there are ways that each of these types can exert their will, but there are perhaps more ways that they have to push back against having their rights infringed upon.
Anyway, I think all four of these types have a great deal in common externally, although their internal worlds can be quite different. What are your thoughts?
