Five Factor Model of personality supported by cross-cultural evidence
“Further research led to the Five Factor Model (Costa & McCrae, 1985; 1995), which identifies Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism as broad, hierarchically organised dimensions of personality. The FFM is supported by extensive cross‑cultural evidence (e.g., Schmitt et al., 2007) and demonstrates high temporal stability and strong psychometric reliability across instruments such as the NEO‑PI‑R and the Mini‑IPIP. Although primarily descriptive, the model has greater potential than earlier trait taxonomies to support biological explanation: individual differences on the Big Five have been linked to genetic influences on neural systems and brain chemistry, offering a tentative account of why traits show stability over time.”
Summary
The Five‑Factor Model correctly identifies Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism and is broadly supported across cultures, albeit with replication challenges in less educated or non‑WEIRD groups. It shows high rank‑order stability and reliable measurement with tools such as the NEO‑PI‑R and Mini‑IPIP. Genetic research confirms substantial heritability and links to brain‑gene expression, though consistent structural brain differences have not been demonstrated.

Even a nonverbal protocol has confirmed the generalizability of the FFM in cross-cultural context (Paunonen, Ashton, & Jackson, 2001). Across cultures, etic studies have generally replicated the FFM (NEO-PI–R: McCrae, 2002; BFI: Schmitt et al., 2007), and factor scales show high internal ...

First, studies using the Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992), and other measures have established that all five factors have strong genetic bases, with heritability estimates from twin studies indicating that about 50% of the variance in personality traits is accounted for by additive and non-additive genetic factors (Jang et al., 1998, Bouchard & Loehlin, 2001). Second, given their genetic roots, it might not be surprising that personality traits are enduring dispositions, with a large body of literature showing high rank-order stability (r ≃ .75) in adulthood (Roberts & DelVecchio, 2000), even after decades (Terracciano et al., 2006a).

Here, we present the first study to systematically evaluate the entire published literature of the association between the Big Five traits and three different measures of brain structure. Qualitative results were highly heterogeneous, and a quantitative meta-analysis did not produce any replicable results.

Although the Five Factor Model (FFM) of personality continues to find cross-cultural support, new research suggests that the model may be difficult to replicate in less educated or preliterate groups and that indigenous social–relational concepts ...

We performed TWAS for each of the ‘big five’ personality traits in EUR (meta-analysis) using FUSION18 and the GWAS summary statistics. We performed a multi-tissue TWAS in 13 different brain subtissues and blood using their respective expression profiles from Genotype Tissue-Expression project (GTEx v8)19.

While they interpret this as possible evidence against universality across cultures, Gosling et al. (31) explain that interitem correlation per se is not necessarily a good indicator of validity for short scales. More generally, Church (32) reviews evidence on cultural differences in personality and concludes that the FFM of personality continues to find cross-cultural support but may be difficult to replicate in less educated populations.
