I want to correct the "pride" description of INFPs...
There are two kinds of pride, in my opinion.
There is the good pride, pride in being something, or pride in something virtuous, and in this sense, the Delta group in Socionics have this pride more than any other group. The Delta's are ESTJs, ISTJs, ENFPs and INFPs.
Those are traditionalists, good people, who follow the norm and tradition, respect authority and consider their character to be the most important thing. There is no room for experience or novelty in their mindset...they are prudent, careful, and a "model" citisen. They are very predictable, and they take great pride in this, because its something they strive for and want to be respected for.
And in this sense, the Delta group has the most to be proud of, and they really are.
To explain this clearly, if four people meet in the same room let's say, each one the "captain" or the leader of his socio-group, respectively a ENTP (from the Alpha group), a ESTP (from the Beta group), a ENTJ (from the Gamma group) and a ESTJ (from the Delta group), naturaly, the common typical ESTJ is in the upper position and advantage, and he knows it very well, and he also knows how to put people "in their place", and how to let them know that he is more worthy of respect as a human being, because he is more self-less, a good worker, with a good character, and trustworthy and dependable (and he can efforthlesly put any ENTP, ENTJ and ESTP "back in their place" if he sees they behave badly or they "step over their attributes". The words of the ESTJs have a moral quality to them, something that appeals to conscience, and that's why they can "put in his place" even a proud ESTP.)
Recently I've saw at my workplace this happening: a ESTJ (kind of 30 years) "taking care" of a naughty ENTJ: it was just incredible, just with a few words, but spoken with power and authority, the ENTJ got quickly calmed down with his silly tricks and impressions of a "bad boy".
That is the thing with the Delta group: they are the standard of what is acceptable for a man to be, and they take great pride in it, and they deserve it. Even ENFPs and INFPs when they get older, most of them have that dependable and trustworhty character in them, and if one is sane with his mind and can think clearly, he can not but give to those people respect, because they deserve it rightly so.
So it is in this sense that the Delta group and of course INFPs too, have that pride in them. They simply know it: they look around and see how many mistakes people make around them, how stupid and inprudent people are, and they just know it...they know what is theirs, what they do have, and they know its better than what others have. Its their pride...
But also, if one knows how to observe people, how to look at them carefuly and with a clear eye, one can observe that beyond that pride that the Delta group deserve it, they have another kind of pride, that pride that is spoken of in the Bible. Its arrogance, a kind of absurd self-confidence in one's own abilitites and a very unshakeable good impression about themselfs.
Not all of them have that, but many of them have it. I know ESTJs who are humble about themselfs, and they follow and love justice, simplity and frugality, but those kind of ESTJ s are very rare.
Most of the ESTJs are very arrogant people, with big mounths, being assholes "in a nice way" because...hey!, they can do it, because they are the best, the model of a good man, and nobody dares to take them into account (actualty, there are a type of people who are not afraid at all to observe and account a ESTJ: they are ESTPs.). And is the same with INFPs...most of them are arrogant and, weirdly so, in spite of their "good pride", their arrogance makes them look very stupid, just like ESTJs.
