diagonaut

A diagnaut is a term sometimes used to describe a person who is overly inquisitive or who attempts to diagnose or explain complex situations, particularly those involving people's behavior or health, often without formal training or sufficient information. The term is a portmanteau of "diagnosis" and "naut," suggesting a journey or exploration into the realm of diagnosis.

Diagnauts may manifest in various contexts. In social settings, someone might be described as a diagnaut if they frequently offer unsolicited psychological interpretations of friends' or family members' actions. In online communities, particularly those discussing health-related topics, individuals who self-diagnose or diagnose others based on limited information are sometimes referred to as diagnauts. This behavior can sometimes be well-intentioned, stemming from a desire to help or understand, but it can also be perceived as intrusive or unhelpful.

The term is not a formal psychological or medical classification. It is more of an informal descriptor used in everyday language. While some diagnauts may genuinely seek knowledge or try to be helpful, their interventions can sometimes lead to unnecessary anxiety or misinformation. The distinction between a curious observer and a diagnaut often lies in the perceived authority, the unsolicited nature of the "diagnosis," and the potential impact on the person being "diagnosed." The act of diagnosing requires expertise and a thorough understanding of symptoms and conditions, which a casual observer typically lacks.
