I don't think I type as INFP out of depression, far from it. I'm actually more likely to type with a higher S percentage now, or as ISFP or even ISTP sometimes because of my realization that I am not terribly abstract, I changed a lot of my perceptions of what "abstract" even meant, I initially thought like most people on the Internet, that all Sensors were simpletons who didn't ever read a lot or do "intellectual" things, but that was a long time ago.
I think I'm more likely to get T-ish scores when I'm depressed too because then I feel very cranky about people, and so I'm more likely to get "hates people" scores which are falsely correlated to T traits. Like "I am blunt and direct" because Fs are always supposed to be sunshine and light and endless good manners?It's funny to me, because when depressed, I type INTP (and probably seem a bit like a disgruntled STJ). When I'm feeling good, liking who I am, being what I see as me (which is my ego, right?), then I'm more likely to test INFP & appear as one.
I've just never valued structure or corporate America very much, but I like money very much. I wouldn't compromise certain things for money though; ultimately my free time, ability to enjoy my life, and relationships with others and ability to do what I want have always been the priority, and money is incidental in making that happen, and I've had the fortune to find tangible but sometimes risky or altertnative ways of making it.The internet gives very narrow & often contradicting ideas of how types appear. There is a LITTLE truth in their caricatures though.
The main difference between those two is fame & looks - outward ways to measure value. The difference between Johnny Depp & an INFP e4 male is just that. Both are equally creepy, but it looks mysteriously sexy & creative when packaged by cheekbones & smoldering eyes & a lot of critical acclaim & success as an actor. (The nice, gentle, eager guy who is a people-pleasing doormat is an ISFJ stereotype often misapplied to INFP...don't get me started on people confusing Si & Fi).
Some of the comments here are basically saying INFP strengths are often not measured in Te ways (fitting some quantifiable measurement) or Se ways (tangible). The strengths have to manifest in those ways or they're overlooked & devalued, even if they are contributing significantly. The most obvious thing is "does it make money?", which is why a lot of INFPs hate money so much. You get a stubbornness to not translate a strength into money making because there are often compromises in integrity. I've seen ISFPs get stuck there also though.
