How about the idea that we're not really misunderstood but just whiny & attached to an image of being difficult to comprehend?
Seriously though, the biggest misunderstanding is one spoken of in many Fi descriptions, but still not grasped even in online forums:
- Appearing cool and unfeeling on the surface, but having deep feeling which amounts to high ideals internally. This feeling steers the individual but is less often expressed verbally to others or with emotion in relation to what stirs it.
This is misunderstood one of two ways:
1. The INFP is a feeling dominant, and therefore will be warm, mushy, & generally excessively demonstrative with emotion. Outside of artistic endeavors, I don't see this as true for most INFPs. This leads to mistypings, IMO, especially with extroverts & probably ISFJs.
2. The INFP is emotional internally, but it's all self-absorbed & this makes them appear cold & selfish. This stems from the beliefs about how feeling is shown or should be shown if it exists (read: Fe). So if not shown that way, then it either does not exist or is selfish.
Online, most perceptions of INFPs don't align with my personal experience, but after getting to know an INFP e9 friend of mine, I see where some stem from. With that, I am referring more to the positive ideas, as she's waaaaay warmer & more expressive with positive feeling than I am. However, she also puts on the "simple, childlike" mask which perpetuates the idea that INFPs are very, well, simplistic & childlike.
