A 2024 meta-analysis found that events like graduating, beginning a new job, marriage, and divorce are associated with modest personality changes, with work-related transitions showing more consistent effects than relationship events (B\u00fchler et al., 2024). Another 2024 study using frequent assessments found that some life events can alter a person\u2019s personality trajectory, though the effects are not always large or consistent (Dugan et al., 2024).[footnote]B\u00fchler, J.
