About the Methodology
What It Measures
The Eysenck Personality Inventory (EPI) was developed by Hans Eysenck and Sybil Eysenck in 1964. The test is based on Eysenck's temperament theory, which describes personality using two independent dimensions: extraversion-introversion and neuroticism-stability. The combination of these dimensions determines four classic temperament types described by Hippocrates: sanguine, choleric, phlegmatic, and melancholic.

Frequently Asked Questions
What is the Eysenck Personality Inventory (EPI)?
EPI (Eysenck Personality Inventory) is a psychological test developed by Hans and Sybil Eysenck in 1964 to measure two main personality dimensions: extraversion-introversion and neuroticism-stability. The test allows determining a person's temperament type and includes a lie scale to verify response validity.
How accurate is the EPI test?
EPI is one of the most scientifically validated personality tests. Its test-retest reliability is 0.84-0.94, and internal consistency is 0.80-0.90. The test has been validated in dozens of countries and has been used in scientific research for over 60 years. However, for maximum accuracy, it's important to answer honestly.
What temperament types does the test identify?
The test identifies four classic temperament types: sanguine (high extraversion, low neuroticism) — active, cheerful; choleric (high extraversion, high neuroticism) — energetic, hot-tempered; phlegmatic (low extraversion, low neuroticism) — calm, balanced; melancholic (low extraversion, high neuroticism) — thoughtful, sensitive.
What does the extraversion scale measure?
The extraversion scale measures personality orientation. Extraverts are oriented toward the external world: they're sociable, active, enjoy company, and easily make acquaintances. Introverts are directed inward: they prefer solitude, deep conversations, and carefully consider their actions. Most people are somewhere in the middle of this scale.
What does the neuroticism scale show?
Neuroticism reflects emotional stability of personality. High neuroticism means a tendency toward anxiety, mood swings, and emotional reactions to stress. Low neuroticism characterizes emotionally stable people who remain calm in difficult situations. This isn't 'good' or 'bad' — it's a temperament characteristic.
What is the lie scale for?
The lie scale (sincerity scale) verifies the validity of your responses. It detects the tendency to give socially desirable answers or present yourself in a better light. If the score on this scale is too high, test results may be unreliable. For accurate results, it's important to answer honestly, even if the answer seems unappealing.
