Communication
How INFJ and ISTJ types talk to each other.
INFJs communicate in an abstract, metaphorical, and meaning-focused way, often speaking in concepts and possibilities. ISTJs communicate more literally, specifically, and fact-based, preferring concrete details and sequential logic.
The challenge is that INFJ's abstract style may seem vague or impractical to ISTJ, while ISTJ's literal approach may feel rigid or uninspiring to INFJ. Success comes from INFJs grounding their ideas in specifics and ISTJs being open to exploring conceptual discussions.
