Note: All stereotypes can be any of the four temperaments, as style is a separate factor to ones temperament.

There are many ways to make a group of people diverse without giving them overly specialized roles within an ensemble. One way is through matching personality types according to a [[ScienceMarchesOn wacky ancient pseudoscience]]. The Four Temperaments (also called the "four humors") was a theory that behavior was caused by concentrations of body fluids -- the "humors" of classical medicine: blood, yellow bile, black bile, and phlegm.

A temporary imbalance would create an illness: too much blood caused a fever, too much yellow bile caused a cough, too much black bile caused depression, and too much phlegm caused a cold. A permanent imbalance led to a person having a certain type of intentions, behavior, and personality. Though this has been a [[ScienceMarchesOn theory long-since discredited from a scientific standpoint]], the general idea still remains and the theory is still used for personality profiling. An ensemble based on these four humors can make the cast diverse without actually changing the roles of the characters in the story.

Along with a list of characteristics, the four temperaments are:

* '''Sanguine (blood):''' Extroverted, emotional, and people-oriented. The following strengths and weaknesses in general gradient order from most phlegmatic to most choleric:

The four temperament system, while interesting, it was flawed as some people did not fit with any of the presented humors, so a neutral temperament has been used, most usually labeled as the '''Leukine''' (also referred to as the supine or the eclectic), although in fiction this has been mostly reserved either for the lead character or more commonly for secondary characters, not to mention this interpretation shares many elements with the Phlegmatic.

Historically in plays, there was a whole genre: Comedy of Humors, where the impetus of the story is the sudden banding of these opposing types. This is in contrast to the Comedy of Errors, where the story is driven by the events and situations.

A FiveManBand cannot itself be a Four Temperament Ensemble, as they're mutually exclusive. They are similar to the four PersonalityBloodTypes, and are sometimes also a FourElementEnsemble.

See also CastCalculus for the overarching archetypes in this and differently numbered ensembles. [[ImageLinks/FourTempermentEnsemble Here is an Image Archive for this trope]]. Additionally, Pseudolonewolf (of ''Videogame/{{MARDEK}}'' fame) has a page that goes into great detail on the four temperaments, [[http://temperaments.fighunter.com here]] (older version with blends [[http://web.archive.org/web/20150324140648/http://archive.fighunter.com/?page=temperaments here]]), and TheOtherWiki offers its information [[http://en.wikipedia.org/wiki/Four_temperaments here]]. For another way to split up a group of four, see FourPhilosophyEnsemble.

[[folder:Tabletop Games]]
* In ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/{{Warhammer 40000}}'', appropriately enough, the four gods of Chaos each represent an emotion and mindset. Khorne the god of anger and bloodshed is choleric. Slaanesh god of passion and lust is sanguine. Tzeentch god of ambition and hope is (ironically) melancholic. Nurgle god of despair and disease is phlegmatic.
