About This Assessment
This assessment measures your self-reported tendencies across the five dimensions of the Big Five (OCEAN) personality model — the most validated framework in personality psychology, backed by over 50,000 peer-reviewed studies across 40+ languages.
The five dimensions are:
- Openness to Experience — your preference for novelty, ideas, and imagination vs. convention and practicality
- Conscientiousness — your preference for structure, planning, and discipline vs. flexibility and spontaneity
- Extraversion — your preference for social interaction and stimulation vs. solitude and depth
- Agreeableness — your preference for cooperation and harmony vs. competition and directness
- Neuroticism — your sensitivity to stress, risk, and uncertainty vs. emotional stability
Why This Matters for B2B Communication
Your personality profile predicts your natural communication style — the messaging patterns you default to. If you score high on Openness, you likely write vision-oriented copy that resonates with similar buyers but misses analytical ones. Understanding your own profile is the first step to broadening your reach. The next step is measuring how your actual writing maps across all five dimensions.
Self-Assessment vs. Text Analysis
This quiz measures how you see yourself. COS measures how your writing actually lands across personality types. These can differ — you might see yourself as balanced, but your emails consistently use high-Openness language that misses Conscientiousness-driven buyers.
The most useful approach: take this assessment to understand your baseline profile, then paste a real message into COS to see whether your writing matches your intent. The gap between self-perception and actual writing patterns is where the biggest communication improvements hide.
Compare your profile to your writing. Paste your most important B2B message and see how it scores across all five OCEAN dimensions.
