Big Five (Five-Factor Model)

The Five-Factor Model, or Big Five, is a product of twentieth-century academic psychology. Between the 1930s and 1960s, researchers noticed that a systematic analysis of adjectives describing people across different languages consistently yielded five stable factors. Independent groups of scholars — Warren Norman, Paul Costa, Robert McCrae, and others — obtained the same result time and again, which became the basis for considering the model universal.

The five factors are Openness to Experience (curiosity and creativity), Conscientiousness (organization and reliability), Extraversion (social engagement and stimulus-seeking), Agreeableness (cooperativeness and trust), and Neuroticism (emotional instability). A crucial point: these are not categories but continuous scales. A person does not "be an extravert" — they score a certain value on the extraversion scale relative to the norms of their culture and age group.

The method relies on formalized questionnaires (NEO-PI-R, BFI, and others) whose results lend themselves to statistical analysis and are reproducible upon retesting. Traits are fairly stable, though they shift with age: conscientiousness tends to increase, and neuroticism on average decreases. The model's predictive validity has been confirmed for academic achievement, professional performance, and relationship quality.

In the Errarium atlas, Big Five occupies a unique position: it is the only system with a high level of scientific verifiability. It does not describe "destiny" and does not appeal to archetypes or the cosmos — it measures what is statistically observable. This makes it a valuable reference instrument for comparison with other methods, yet fundamentally different in nature: where astrology seeks symbolic correspondences, Big Five seeks mathematical regularities.
