Is the personality-Politics link stronger for older people?

Two personality dimensions of the HEXACO model-Honesty-Humility and Openness-have previously been found to correlate with left-wing political orientation. From a cross-sectional dataset divided into samples from the USA (N = 77,778) and other countries (N = 105,232), the Openness/politics link showed a linear upward trend across age cohorts, whereas the Honesty-Humility/politics link did not. These results may suggest that the aspect of political orientation primarily linked to Openness (e.g., social progressiveness) is influenced by early life experience, but gradually changes to align with one's level of Openness, whereas the aspect of political orientation primarily linked to Honesty-Humility (e.g., egalitarianism) is influenced by that dimension rather consistently across the lifespan.
