# About FourType Learn who created FourType, how the temperament test content is written, and how to use the quiz responsibly. FourType is a free four temperaments quiz and self-reflection project created by Ian Goh. It is designed for practical self-knowledge, not clinical diagnosis, hiring, medical, or high-stakes assessment. The project separates ancient temperament language from modern personality science and explains Choleric, Sanguine, Melancholic, Phlegmatic, and blended subtype patterns in everyday terms. ## Keep exploring temperament tests - [Best Temperament Test](https://www.fourtype.com/blog/best-temperament-test) - Compare FourType with other temperament tests before choosing a quiz. - [Temperament Test Comparison](https://www.fourtype.com/blog/temperament-test-comparison) - Compare FourType with OSPP, IDRlabs, Truity, Psych Central, and more. - [IDRlabs vs FourType](https://www.fourtype.com/blog/idrlabs-temperament-test-vs-fourtype) - Compare academic-style temperament testing with FourType. - [JobCannon vs FourType](https://www.fourtype.com/blog/jobcannon-temperament-test-vs-fourtype) - Compare a short temperament quiz with a deeper FourType result. - [Truity vs FourType](https://www.fourtype.com/blog/truity-temperament-test-vs-fourtype) - Compare 16-type temperament with classical four temperaments. - [FourType Methodology](https://www.fourtype.com/methodology) - How the temperament test is scored and interpreted. - [Best Temperament Test](https://www.fourtype.com/blog/best-temperament-test) - Compare FourType, OSPP, IDRlabs, Truity, JobCannon, and other tests.
