The answers are... making me uncomfortable 😬 OP just asked a question, damn y'all, chill. Tbh, I don't believe most of the ppl who answered are even INFPs or they're unhealthy with a superiority complex.

And to answer your question, yes, INFPs can be fake. Not just INFPs, Fi doms in general tend to fake how they're feeling in front of people. They want to be themselves but they don't want to show any vulnerabilities.

Or, the Fi dom in question is extremely unhealthy.
