Abstract

Describing and understanding personality structure is fundamental to predict and explain human behavior. Recent research calls for large personality item pools to be analyzed from the bottom-up, as item-level analysis may reveal meaningful differences often obscured by aggregation. This study introduces and applies Taxonomic Graph Analysis (TGA), a comprehensive network psychometrics framework aimed at identifying hierarchical structures from the bottom-up, to an open-source 300-item IPIP-NEO dataset (N = 149,337). This framework addresses key methodological challenges that have hindered accurate recovery of hierarchical structures, including local independence violations, wording effects, dimensionality assessment, and structural robustness. TGA revealed a three-level structure composed of 28 first-level dimensions (facets), 6 second-level dimensions (traits), and 3 third-level dimensions (meta-traits). Although some dimensions aligned with the theoretical IPIP-NEO structure, there were considerable deviations including the emergence of Sociability, Integrity, and Impulsivity traits at the second-level and a novel Disinhibition meta-trait at the third-level. The overarching theme of our findings was a hierarchical structure that integrated empirical and theoretical findings that have been scattered across the personality literature, demonstrating TGA's value to investigate hierarchical psychological constructs. This study contributes to discussions on personality taxonomy by providing a rigorous, data-driven perspective on the IPIP-NEO's hierarchical structure.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-04:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 18.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 18 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 59.
  • The number of mentions on the social network X (formerly Twitter): 13 (Altmetric).
  • The number of mentions in news outlets: 4 (Altmetric).
