The belief that people can be placed within a personality typology has persisted for millennia. At least as far back as Hippocrates (ca. 460 BCE–370 BCE) people were believed to be of a kind based on the four humors—blood, yellow bile, black bile, and phlegm. Since then, there have been many conceptions of personality typologies. The Myers-Briggs Type Indicator and the Enneagram of Personality are likely the most well-known personality typologies among the general public. Despite their wide public usage, neither typology boasts strong empirical support. However, psychology continues to investigate personality for evidence of a typology of personality. In line with the research conducted by Gerlach et al. (2018) and Ferguson and Hull (2018), the current study analysed the 30 facets of the International Personality Item Pool 300 (IPIP-NEO-300) for evidence that personality exists as unique configurations of facet level personality types. Results of the Latent Profile Analysis performed on each of 12 dataset groupings revealed 3 facet-based personality types. These revealed types correspond partly with the Resilient, Overcontrolled, and Undercontrolled personality profiles previously uncovered in independent research by Asendorpf et al. (2001), Robins et al. (1996), and Caspi and Silva (1995)—the so-called ARC types.
