Commentary: A robust data-driven approach identifies four personality types across four large data sets

An alternative interpretation of Gerlach et al. (2018) result is proposed: a skewed distribution with no cluster structures in personality space can erroneously lead to the seemingly meaningful clusters.

Four personality types may be neither robust nor exhaustive

While it is concur that the authors’ analyses reveal four meaningful clusters in the Johnson-300 data, it is found that only 42% of the sample was associated with those four personality types, and the vast majority of individuals could not be classified within a distinct, meaningful cluster.

Personality types revisited–a literature-informed and data-driven approach to an integration of prototypical and dimensional constructs of personality description

Wether personality types could comprise a bridge between personality and clinical psychology as well as between developmental psychology and resilience research is discussed and reliability and construct validity could be confirmed.

Individual and Group Differences in Multivariate Domains: What Happens When the Number of Traits Increases?

This paper offers a systematic but accessible treatment of individual and group differences in multivariate domains, with a focus on high-dimensional phenomena and their theoretical implications.

Establishing the structure and replicability of personality profiles using the HEXACO-PI-R

HEXACO theory along with agency–communion and attachment theories are used along with parameter estimates provided by research to generate and test hypotheses to validate the five-profile structure and evaluate its utility for personality research and other applications.

Personality beyond taxonomy.

A set of causal hypotheses about the role of personality are offered, integrating psychological and neuroscientific approaches to personality in a testable framework, and it is argued that articulating and testing such models will be essential in a mature science of personality.

An Investigation of Personality Types within the HEXACO Personality Framework

Recent research aimed at identifying distinct personality types has generally searched for such types in the space of the dimensions of the Big Five or Five-Factor model. We extended this search to

The generality of this 5-factor model is here demonstrated across unusually comprehensive sets of trait terms, which suggest their potential utility as Big-Five markers in future studies.

This research demonstrates that replicable and generalizable personality types can be identified empirically, and that the unique constellation of traits defining an individual has important consequences for a wide range of outcomes.
