The Fascinating Origins and Evolution of the 4 Personality Types 🧠


Video: The 4 Personality Types – Which One Are You?








From Ancient Humors to Modern Psychology

The roots of the 4 personality types test stretch back over 2,000 years to Ancient Greek medicine. Physicians like Hippocrates and later Galen believed human health and temperament were governed by four bodily fluids or “humors”:

Humor Associated Temperament Characteristics
Blood Sanguine Sociable, lively, optimistic
Yellow Bile Choleric Ambitious, leader-like, fiery
Black Bile Melancholic Thoughtful, reserved, sensitive
Phlegm Phlegmatic Calm, reliable, peaceful

Galen coined these terms to describe how imbalances in humors influenced personality and health. Fast forward to today, and the theory has morphed into a psychological model rather than a medical one.

Why It Still Matters

Despite lacking scientific backing as a medical theory, the Four Temperaments endure because they capture fundamental human behavioral patterns in a simple, memorable way. They’re the granddaddies of many modern personality tests, including the popular DISC and even elements of Myers-Briggs.

Our team at Personality Types™ loves how this ancient wisdom still sparks self-discovery and interpersonal understanding. Want to dive deeper into the history? The OpenPsychometrics O4TS test page offers a fascinating overview.

Meet Sarah, the Sanguine Social Butterfly

Tips and Tricks: How to Get the Most Accurate Results from Your 4 Personality Types Test 🎯

1. Be Honest — With Yourself!

The most common pitfall is answering how you wish to be rather than how you are. Authenticity yields the best insights.

2. Take Your Time

Don’t rush through the statements. Reflect on each one carefully to avoid skimming or default answers.

3. Consider Multiple Tests

Try different versions (like O4TS, Truity, and 16Personalities) to see patterns and consistencies.

Remember, personality is fluid. Use your results to explore, not to box yourself in.

6. Share and Discuss

Talking about your results with friends, family, or counselors can deepen understanding and reveal blind spots.

7. Revisit Periodically

Personality can evolve. Retake the test every year or so to track changes and growth.
