What Laypeople Think the Big Five Trait Labels Mean. Judith A.Hall et al. Journal of Research in Personality, https://doi.org/10.1016/j.jrp.2018.12.007

Highlights
•    Laypeople were able to describe how they apply the Big Five traits in daily life.
•    Each trait had 9 to 13 facets that varied in their centrality to the trait.
•    Lay beliefs corresponded generally well with standard Big Five inventories’ content.
•    But there were notable disjunctions between lay beliefs and inventories’ content.

Abstract: We asked what laypeople think the commonly used Big Five trait labels mean, and how well their beliefs match the content of standard Big Five scales. Study 1 established participants’ familiarity with the Big Five trait labels. In Studies 2 and 3, participants described persons high on the traits using a free response format. Responses were sorted into categories (facets), each of which earned a centrality index defined as the proportion of responses for the given trait that fell into that category. Studies 2 and 3 converged well. Comparisons with four standard Big Five inventories revealed substantial commonality but also notable areas of non-overlap consisting of content identified by laypeople that was not represented in the standard scales, as well as content in the standard scales that was not mentioned by laypeople.
