i don't think jerry's character is very well-defined on the show.
obviously Fe and not Fi. obviously Ti and not Te. probably I based on the group of friends he has (tho he is the most extraverted one). definitely j. and definitely N instead of S.
in real life he's gotta be an intp. infj as played by an intp? and who is the real larry david, is he really an infj as he often gets typed?
george intp (inferior Fe, dom Ti, probably Ne and why he and jerry make such a good team, discussing possibilities at the cafe, very nuts and bolts, cause cause cause)
elaine estj (she has her own values, she's not necessarily in touch with them, but they feel Fi not Fe, she's always wondering how to convey something and asking the help of jerry and george. she seems more Te to me than Ti like george and jerry).
kramer istp (possibly Ne, but overall he is strangely literal at almost all times, wacky but he seems more Se to me than Ne, sensualist and in-the-moment, he is very poorly defined as well)
newman entp (jerry's strange antithesis, Ne, Ti, probably Fe and not Fi)
if jerrys character is an infj, he's a 4w3. george would be a 6w5.
