Since that time, the construct has been variably reinterpreted through competing theoretical lenses, ranging from Kraepelin\u2019s biological nosology to contemporary cognitive-behavioral and multidimensional models. Despite its clinical relevance across disorders (e.g., anorexia nervosa, body dysmorphic disorder, obsessive\u2013compulsive disorder), overvalued ideas remain inconsistently and insufficiently defined, having been alternately treated as attenuated delusions, markers of poor insight, or disorder-specific severity indicators\u2014interpretations that have limited theoretical coherence, measurement precision, and clinical utility. This review traces the historical evolution of the overvalued idea, clarifies enduring theoretical misinterpretations, and proposes a comprehensive, practical definition. Integrating historical and contemporary perspectives, we define an overvalued idea as a psychologically intelligible, ego-syntonic belief held with disproportionate emotional significance that dominates cognition and behavior without meeting criteria for an obsession or a delusion. We further propose that overvalued ideation is best conceptualized as a transdiagnostic mechanism through which emotionally reinforced beliefs acquire pathological dominance across disorders, a formulation that both honors Wernicke\u2019s original insight and can be operationalized for future research, measurement, diagnosis, and treatment.<\/jats:p>","DOI":"10.3390\/bs16050708","type":"journal-article","created":{"date-parts":[[2026,5,5]],"date-time":"2026-05-05T10:01:30Z","timestamp":1777975290000},"page":"708","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Overvalued Ideas: Conceptual Analysis and Literature Review"],"prefix":"10.3390","volume":"16","author":[{"given":"Jennifer","family":"Dork","sequence":"first","affiliation":[{"name":"Department of Psychology, Grand Valley State University, Allendale, MI 49401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eugene","family":"Dimenstein","sequence":"additional","affiliation":[{"name":"Department of Psychology, Grand Valley State University, Allendale, MI 49401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0081-9350","authenticated-orcid":false,"given":"Lawrence","family":"Burns","sequence":"additional","affiliation":[{"name":"Department of Psychology, Grand Valley State University, Allendale, MI 49401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan","family":"Demshuk","sequence":"additional","affiliation":[{"name":"Department of Psychology, Grand Valley State University, Allendale, MI 49401, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.35516\/jjas.v21i1.4143","article-title":"Narrative literature reviews in scientific research: Pros and cons","volume":"21","author":"Ahmad","year":"2025","journal-title":"Jordan Journal of Agricultural Sciences"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Ahmad, S.
