Based on Pliny's panegyric which focuses on the imperial virtues of ancient Rome, scales of the Via Romana are constructed and compared with the Big Five and HEXACO. Convergent validity is hypothesized because: there are strong paths of cultural transmission from ancient Rome to modern times; the Via Romana, the Big Five and HEXACO are lexically designed; they share a basis in a stranger's personality; and they measure surface personality traits. Regression shows that between 25% and 47% of variance in Big Five scales is explained by the Via Romana with somewhat less in the HEXACO. Although demonstrating useful convergent validity, overlap between the Big Five and HEXACO models with 2000 year old obsequious rhetoric is also potentially problematic.

普林尼（Pliny）以古罗马帝国美德为重点的古希腊语的基础上，建造了罗马古罗马大道（Via Romana）的规模，并将其与“大五国”（Big Five）和“十六进制”（HEXACO）比较。假设收敛效度是因为：从古罗马到近代，有很强的文化传播路径；Via Romana，Big Five和HEXACO是按词法设计的；他们在一个陌生人的性格中有着共同的基础；他们测量表面的人格特质。回归表明，通过罗马罗马语可以解释“大五”音阶中25％到47％的方差，而在HEXACO中则少一些。尽管证明了有用的收敛效度，但是具有五年历史的夸张言论的“五巨头”和HEXACO模型之间的重叠也可能存在问题。
