Relationships and the Big Five: Compatibility Patterns Backed by Research

Introduction

When it comes to love, do opposites attract, or do birds of a feather flock together? The Big Five model offers some clear answers based on extensive relationship research.

The Similarity Effect

Generally, similarity predicts higher relationship satisfaction. Partners who share similar levels of Openness, Conscientiousness, and Agreeableness tend to have fewer conflicts. For example, if one partner loves trying new restaurants (High Openness) and the other hates leaving the house (Low Openness), friction is inevitable.

The One Trait That Matters Most

Research consistently shows that Neuroticism (or rather, the lack of it) is the strongest predictor of relationship success. High Neuroticism in one or both partners is correlated with relationship dissatisfaction and instability.

Agreeableness: The Buffer

High Agreeableness acts as a buffer against conflict. Agreeable partners are more likely to forgive, compromise, and interpret their partner's actions in a positive light.

Dominance and Extraversion

This is one area where "opposites" might work better. Two highly dominant Extraverts may struggle for control, while a dominant Extravert and a submissive Introvert might find a natural balance.
