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 [[ScienceMarchesOn this theory has long since been 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.

The four temperament system was an interesting one, but flawed. Several tests noticed people that did not conform to any of the behavior types, so a neutral temperament was created. Along with a ''sampling'' of related tropes, the five temperaments (humors) are:

* '''Sanguine (blood):''' Extroverted, Emotional, and People-oriented

* '''Leukine (white blood cells) [[note]]Also referred as Supine[[/note]]:''' Ambiverted and dually-oriented. The "central" temperament that was created for those who didn't have one of the four clearly-established temperaments. This type of character can generally be described as middle-of-the-road and neutral. Generally calm, rational, [[TheQuietOne quiet]], and [[TheReliableOne reliable]]. Usually confused with the phlegmatic, but this temperament tends toward either [[TheStoic true apathy]] or rotating among nearly ''all'' the world's emotions (nothing too explosive or extreme) at a smooth, gradual rate. In a positive light, having more than one temperament or balanced among temperaments; but in a negative light, a [[FlatCharacter non-temperament]], TheGenericGuy, and a StandardizedLeader. Usually reserved for protagonists, TheHero or other [[TheLeader leaders]] when they are neither HotBlooded nor emotionless characters, and somewhat more independent but not as introverted.
** Expressive moderate, responsive moderate; response's delay variable, duration variable.
** Will often correspond with the Conflicted or the Apathetic when in a FourPhilosophyEnsemble.
** Archetypal color: White or Gray.

Some sets of four form a "Combo Ensemble", blending two adjacent temperaments each based on a common aspect. These temperament combos also form the basis for the MyersBriggs Temperament Indicator.

* '''Sanguine''' and '''Choleric''' (the '''Artisan'''): [[ExtraversionTropes Extroverted]] and dually-oriented. On the positive side, the most brave, [[TheMcCoy passionate]], energetic, and often, bun not always, tactical (as "[[MyersBriggs/ExamplesOfArtisanPersonalitiesInStories Artisan]]" suggests) of the temperament combos. But on the negative side, the most impulsive and emotional, and can [[DramaQueen cause the most drama to happen]]. Can range from [[TheRealMan Real Man]] (especially as TheMunchkin), to {{genki|Girl}} BloodKnight if viewed in a negative light, and almost always highly selfish. Characters on the side of good with this combo tend to be {{Hotblooded}}, with some {{Idiot Hero}} tendencies. Also seems to be popular for Shonen {{Anime}} [[TheHero heroes]].
** Expressive high, responsive moderate; response's delay short, duration variable.
** Corresponds to the double-element [[ShockAndAwe lightning]] ([[BlowYouAway air]] + [[PlayingWithFire fire]]).
** Often the Realist and/or the Optimist in a FourPhilosophyEnsemble.
** Archetypical color: Red, Gold, or Crimson (colors of wealth/royalty)

* '''Choleric''' and '''Melancholic''' (the '''Rational'''): Ambiverted and task-oriented. The temperament combo most calculative (as "[[MyersBriggs/ExamplesOfRationalPersonalitiesInStories Rational]]" suggests), very decisive, and insistent on things being in line with the LawfulGood. Especially good in instructing with authority and preventing bad influences over or hindrances against the project at hand, as well as having things calculated so that a decision can be made at a decent speed. On the flip side, quite prone to [[SevenDeadlySins greed, gluttony]], hypocrisy, {{manipulati|veBastard}}on, and a judgmental, HolierThanThou demeanor. Less polite and more [[AntiHero devious]] than s/he may appear to be. Can be a MoodSwinger and [[DontYouDarePityMe suspect and/or resent sympathy]] from anyone else. Tendency less to forgive and more to be [[NeverMyFault harsh in blaming others]]. Often can be TheSmartGuy in terms of common sense and [[TheSneakyGuy craftiness]]; also can be InsufferableGenius. The temperament combo most susceptible to being a GrumpyBear, {{Tsundere}}, RulesLawyer, KnightInSourArmor, relentless leader-like version of NeatFreak, or a KnightTemplar. A villainous extreme would be such things as StrawHypocrite and TheCaligula. For [[TheHero heroes]], the IWorkAlone factor is common, coupled with a hidden GoodIsNotNice that eventually slips out.
** Expressive moderate, responsive low; response's delay variable, duration long.
** Corresponds to the double-element [[MagmaMan lava/magma]] ([[PlayingWithFire fire]] + [[DishingOutDirt earth]]).
** Often the Apathetic, but usually TheCynic in a FourPhilosophyEnsemble.
** Archetypical color: Orange, Brown, all shades of Olive or Black (colors of [[SeriousBusiness seriousness]])

* '''Melancholic''' and '''Phlegmatic''' (the '''Idealist'''): [[IntroversionTropes Introverted]] and dually-oriented. The most sensitive, deep-feeling, mannerly temperament combo and, as "[[MyersBriggs/ExamplesOfIdealistPersonalitiesInStories Idealist]]" suggests, the most focused on the abstract and character ideals. Also very intuitive and focuses on following the rules and seeing justice and goodness done, being the community's moral compass. On the negative side, it is the most shy, timid, neurotic, and prone to harbor ''hurt feelings'', being extremely prone to be InnocentlyInsensitive. Has some particular expectations of others, but in most common cases [[ShrinkingViolet too timid to express them]]. May brood at times; tends to be [[GuiltComplex harsh in blaming the self]] and others. Often TheSmartGuy or the {{Adorkable}}. Can range from [[BadassBookworm bookish]] NiceGuy to {{Kuudere}}[=/=]SugarAndIcePersonality. On TheHero's side, BewareTheNiceOnes (if not a DeathGlare) is almost always a factor.
** Expressive low, responsive moderate; response's delay long, duration variable.
** Corresponds to the double-element [[GreenThumb plant]] ([[DishingOutDirt earth]] + [[MakingASplash water]]).
** Usually the Conflicted in a FourPhilosophyEnsemble.
** Archetypical color: Black, all shades of Green or Turquoise (colors of humility)

* '''Phlegmatic''' and '''Sanguine''' (the '''Guardian'''): Ambiverted and people-oriented. The temperament combo that thrives most on relationships with other people and is the most emotionally strong for other people. Usually the most easygoing and least judgmental; and, as "[[MyersBriggs/ExamplesOfGuardianPersonalitiesInStories Guardian]]" suggests, supportive and helpful at ''guarding'' a team or family from falling apart. On the flip side, often overly tolerant and/or permissive; also the most prone to laziness (either TheSlacker or BrilliantButLazy), being often sluggish about any task that requires spending a bunch of mental energy. Often evaluates other people in a ''very'' optimistic light, an overlap of ThePollyanna and the WideEyedIdealist (distinct from the ''above'' "Idealist"). Usually the diametric ''opposite'' of an InsufferableGenius or NeatFreak. Taken to an extreme, can be a CloudCuckoolander.
** Expressive moderate, responsive high; response's delay variable, duration short.
** Corresponds to the double-element [[AnIcePerson ice/snow]] ([[MakingASplash water]] + [[BlowYouAway air]]).
** Often the Conflicted, but usually the Realist in a FourPhilosophyEnsemble.
** Archetypical Color: Lavender, White, all shades of Aqua or Pink (colors of youthfulness)

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.

Sometimes a FiveManBand will also be a Four (or often Five) Temperament Ensemble, but in many cases, they're mutually exclusive. There is also some overlap with PowerTrio scenarios: usually TheKirk is choleric, TheMcCoy is sanguine, and TheSpock is melancholic. In these cases, the phlegmatic role will be filled by a prominent supporting character, who is still clearly outside of the triad. They are also similar to the four PersonalityBloodTypes, and are sometimes also a FourElementEnsemble.

If this type of personality dynamic is used for a FiveManBand, then there are -- aside from TheHero as leukine and TheChick as phlegmatic -- two very common sets: either TheLancer (choleric), TheSmartGuy (melancholic), and TheBigGuy (sanguine); or TheLancer (sanguine), TheSmartGuy (choleric), and TheBigGuy (melancholic). [=RPGs=] in particular like to use a simplification of the second type.

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 {{MARDEK}} fame) has a page that goes into great detail on the four temperaments, [[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]]
* Intentionally invoked in ''TabletopGame/PrometheanTheCreated''. The five Lineages of Prometheans are Frankensteins (choleric), Tammuz (melancholic), Galateids (sanguine), Osirans (phlegmatic), and Ulgan (associated with the "humor" of ectoplasm.) The character's balance of humors is actually an important gameplay point.
** The Unfleshed, introduced as a full Lineage in the second edition core, are associated with the "humor" of oil.
* Also invoked in ''TabletopGame/Tribe8'' with the monstrous Z'Bri, whose 4 types are named after the four humors (of the '''old''' model): Koleris, Flemis, Sangis, and Melanis.
* ''TabletopGame/MagicTheGathering'' has this with the five Praetors of New Phyrexia:
** Choleric: [[KnightTemplar Elesh Norn]].
** Melancholic: [[MadScientist Jin-Gitaxias]].
** Phlegmatic: [[TheStarscream Sheoldred]].
** Sanguine: [[VillainousGlutton Vorinclex]].
** Leukine: [[DarkChick Urabrask]].
* While ''TabletopGame/{{FATAL}}'' does have a humors system, there is no rule forcing your party to be a FourTemperamentEnsemble. Indeed, this would actively contradict the obsessive randomisation inherent to the FATAL system.
* 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; and Nurgle (god of despair and disease) is phlegmatic.
[[/folder]]

[[folder:Theatre]]
* The final Creator/HasseOchTage revue ''Fröken Fleggmans mustasch'' is constructed around this trope, to the extent that the characters of the four person ensemble (if one excludes the pianist) are ''named'' accordingly. The quartet consists of:
** Count Niklas von Sanguin (played by Creator/HansAlfredson).
** The banker Kurt S.[[note]]Stubin[[/note]] Wresig, alternatingly his [[spoiler:impostor]] son Kolerik Wresig (both played by [[Creator/GostaEkman Gösta Ekman]]).
** The maid Frida Fleggman (played by Creator/LenaNyman).
** The [[IdentityAmnesia Mysterious Stranger]] Alvar F.[[note]]Ragnar (ItMakesSenseInContext)[[/note]] Dysterkvist (played by Creator/TageDanielsson).
* In Mozart's opera ''DonGiovanni'': Donna Elvira (choleric), Masetto (choleric/melancholic), Donna Anna (melancholic), Leporello (phlegmatic), Zerlina (sanguine), Ottavio (sanguine/choleric), and Commendatore/Don Pedro (leukine/phlegmatic).
