This conceptual paper proposes the Expertise Paradox as a conditional, interaction-level process. Professional expertise enables informed judgement, and under some conditions it may interfere with the interpersonal behaviour through which that expertise becomes useful to another person. When an expert's established knowledge frame dominates attention and interpretation, the expert may define the other person's problem prematurely, respond before fully understanding it, and fail to enact interpersonal skills that he or she may otherwise possess. The paper makes four contributions. It distinguishes competence in interpersonal skills from their momentary enactment in a particular exchange. It specifies a discrepancy between expert-perceived effectiveness and recipient-experienced understanding as a potential observable outcome. It connects the proposal to research on cognitive entrenchment, the curse of expertise, perspective taking, communicative overconfidence, and responsiveness to interpersonal feedback. And it adds a proposition on digitally mediated communication, where the cues that would otherwise reveal misunderstanding are largely absent. Seven propositions, competing explanations, boundary conditions, and an empirical research programme are outlined. The framework is descriptive rather than normative, and the paper states its normative starting position separately: approach the other person as a person first, and do not assume that being an expert guarantees a good exchange. This is a theory-building manuscript. No empirical data are claimed. The construct emerged from long-standing practitioner observation and requires systematic testing before it can be treated as an established explanation. Comments and critical engagement are welcome. This paper is a single chapter of a larger work in progress, The Human Advisor: Trust Across Cultures.
