This document discusses a study investigating how the Big 5 personality traits may affect participation in open online environments. The Big 5 model categorizes personality into 5 dimensions: extraversion, agreeableness, conscientiousness, neuroticism, and openness. The study aims to understand how these personality traits relate to inclusion and participation online. Previous research has found personality expression decreases online compared to offline for some traits. The proposed study will involve participants completing a personality assessment then discussing their experiences with open online environments. Results could inform how personality impacts inclusion in such spaces.
