The **IPIP-300** is a psychological inventory based on the **Big Five** model (or the five major personality factors), developed as part of the International Personality Item Pool (**IPIP**).

This version uses scores calculated with the [Five-Factor-E](https://github.com/NeuroQuestAi/five-factor-e) library, providing accurate and reliable analysis of personality traits.

Comprising 300 items, it provides a comprehensive assessment of the five major personality traits:

- Openness
- Conscientiousness
- Extraversion
- Agreeableness
- Neuroticism

The IPIP-300 is widely used in academic research and projects that require a detailed and accurate analysis of personality. The larger number of items allows for a more robust and in-depth evaluation of the specific subfacets within each trait.
