The 4-personality type system, known as the four temperaments, is ==an ancient theory that divides people into sanguine, choleric, melancholic, and phlegmatic types==. Rooted in ancient Greek medicine, the theory suggests these temperaments were once thought to be determined by an excess of specific bodily fluids (humors). Modern interpretations view them as a way to understand different personality traits, such as sanguine being cheerful and enthusiastic, choleric being goal-oriented and decisive, melancholic being analytical and sensitive, and phlegmatic being calm and diplomatic.  ![[The four temperaments_5442.webp]] The four temperaments - **[Sanguine](https://www.google.com/search?q=Sanguine&ie=UTF-8&oe=UTF-8&hl=en-gb&client=safari&mstk=AUtExfDiqsrJHbeZCsapxL6l8LUtU48Znpmm-tedJw6lBdaJJykgcvN4nkr3XfccW9wrk80X343EszX8JicMzml9no96F37Uxe3UMFP2_tZVNC7lpIyRpO1xEFqAaUTCUM3nwJDBiFH0eOR5hjXOwhj1t98XRYK8AenSllLcTwvOohTEjPq79YSYpHpdD97D0xZLp16LYexN8UOUD-N_O0lqLiXsqf0Kmn9Xpr368LodbqddlmCz81XtBX-qCmZAVqJ3QPaZeLT4eIXL9Cl6F2gszM3L&csui=3&ved=2ahUKEwiDrIrUoYuRAxX7dUEAHVS0OxgQgK4QegQIAxAB):** Characterized by sociability, enthusiasm, and optimism.
