# Personality Genetics Linked to Health, Career, and Life Outcomes

New study links Big Five personality genetics to diverse life outcomes including health, income, and longevity.

An international consortium of researchers found that more than 1,200 different genetic variants are associated with the Big Five personality traits. [^1]

The study focuses on developing and evaluating a structured and generalizable framework for automatically generating personality situational judgment tests using large language models. [^2]

Participants in each cohort provided a DNA sample and completed a questionnaire measuring the Big Five personality traits: openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism. [^3]

The study combined results from 46 different research cohorts around the world and published its findings in the journal Nature. [^4]

The study found that genetic variants associated with neuroticism predict more time spent in the hospital, and variants associated with openness to experience are linked to income and switching jobs. [^5]

Study 1 systematically compared the effects of prompt design and temperature settings on the content validity of LLM-generated items. [^6]

Study 3 evaluated the psychometric properties of LLM-generated SJTs covering five facets of the Big Five personality traits. [^7]

The researchers used GPT-4 and ChatGPT-5 as empirical examples to test the automatic item generation approach. [^8]
