[[ExactlyWhatItSaysOnTheTin As its name implies]], [=Saddlesoap Opera=]'s [[http://www.equestriadaily.com/2011/06/story-pony-psychology.html Pony Psychology]] series delves into the minds and personal problems of the main cast of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', with [[AlternativeCharacterInterpretation their own interpretation]] of their more... unstable moments. In order, the series goes:

* '''Fluttershy: Origins''': After the [[Recap/MyLittlePonyFriendshipIsMagicS1E26TheBestNightEver Grand Galloping Gala]], Fluttershy reflects upon her actions and how much it reminds her of [[DarkAndTroubledPast her childhood]].
* '''Pinkie Pie: Schism''': Rainbow Dash accidentally catches Pinkie Pie in an unguarded moment, discovering an uncomfortable secret -- and as we all know, spilling a secret is the fastest way to lose a friend FOREVER!
* '''Rainbow Dash: Dependence''': Dash turns to Fluttershy for help relaxing, but the cure may be worse than the original problem...
* '''Applejack: Exposure''': Applejack takes a lot of pride in being honest, but when that honesty extends to sharing ''all'' her feelings, complications quickly ensue.
* '''Rarity: Loss''': Rarity may be generous, but all her giving has a hidden cost -- and that's becoming too much to bear.
* '''Twilight Sparkle: Spellbound''': As her friends' struggles with their personal problems reaches the breaking point, Twilight learns an AwfulTruth from her mentor, one she must come to terms with if she's to have any hope of helping anyone.

In addition, the series has several side stories:

* '''Alicorns: Blame''': The truth behind the thousand year-schism between the Princesses comes to light, and is considerably more complex than the old fable of "The Mare in the Moon".
* '''Ditzy Doo: Muffins''': What is it with Ponyville's walleyed mailmare? Why does she have a unicorn foal? What does her Cutie Mark mean? And why is she so fixated on muffins? Is she an amnesiac CIA agent or something?
* '''Trixie: Treasure''': The once Great and Powerful Trixie comes into possession of the means to get back at the residents of Ponyville - but is she ready to pay the price for that vengeance?

A sequel, "Secrets and Lies", has been completed. Set after the end of Season Two, it leads off with a bang when Twilight is forced to kill Topsy Turvy/Screwball in self-defense. Having to hide that from the others leads to problems.

* ArentYouGoingToRavishMe: At one point, Rarity assumes that [[spoiler:the Mayor's hints about taking a bribe to turn a blind eye to her unpaid taxes]] mean something entirely different. When she realizes the truth, all her horror and shock at her assumption being proven wrong is directed inward.

* TheEvilsOfFreeWill: In ''Treasure'', Twilight Sparkle is struck by the thought that [[spoiler:Pinkie Pie was finally freed of her depression and made truly ''happy'' by losing her free will]]. It's a sobering thought, and one that makes her [[spoiler:submit to being taken back to Trixie]].
* FantasyCounterpartCulture: Stalliongrad might be the most prominent example, that with a royal visit from tsarevna in ''Spellbound'' (and with perfect Russian to boot). Then there are mentionings of Xiao Ma, San Caballo and Puledria.
* {{Foreshadowing}}: Each installment foreshadows future events in small ways.
* GetAHoldOfYourselfMan: Twilight telekinetically slaps Rarity in ''Loss''.
* {{Glamour}}: In ''Blame'', Nightmare Moon's striking appearance and natural intimidation is explained as the effects of a mantle Luna wore, which originally belonged to the princesses' mother. [[spoiler:Celestia wears one all the time, and its effects are so powerful even Luna can't fully resist its thrall -- something which causes her no end of frustration.]]
* GoneHorriblyRight: [[spoiler: Luna wanted to remove the ponies having to [[PaintingTheFrostOnWindows change the seasons and everything themselves]]; the Everfree Forest, the most feared and hated place in Equestria, is the result.]]

-->"I'm flattered, but I'm just not interested. Personally, I ''love'' the co– ''come right in! Welcome to Carousel Boutique!''"
* LoveTriangle: [[spoiler: Applejack and Fluttershy, for Rainbow Dash.]]
* TheMagnificent: Parodied in ''Treasure'', where Trixie is frequently described not just as The Great and Powerful, but in terms suited to her current state, such as The Typical and Commonplace or The Shaky and Anxious.
* MalfunctionMalady: Trixie's use of the Regalia of the Daymare to punish Ponyville for the end of her career almost killed her.
* MafiaPrincess: ''Muffins'' reveals [[spoiler:Gilda the Griffon]] as one. [[spoiler:By the end, she's implied to be taking over her late Uncle's business.]]
* MamaBear: Ditzy Doo.
* MiddleChildSyndrome: [[spoiler:Trixie had so many siblings that her parents were hard-pressed to care for them all, leaving Trixie feeling neglected and longing to be seen]].
* ObfuscatingStupidity: [[spoiler: the ending of Muffins clearly implies that Bright Eyes/Ditzy Doo is only feigning being a [[TheDitz clumsy scatterbrain]] again because it's the only way to [[MamaBear keep Dinky safe]].]]
* [[PeoplePuppets Pony Puppets]]: Trixie inflicts this punishment upon [[spoiler:Snips and Snails]] for humiliating her in the past.
* PowerAtAPrice: [[spoiler:The Elements of Harmony slowly drive their bearers mad.]]
* PrecisionFStrike: ''Treasure'' has a variant when [[spoiler:Applejack stands up to Trixie -- "My Granny's cookin' is FAN-BUCKIN-TASTIC!"]]
* RageAgainstTheReflection: Pinkie's story has her staring into a mirror. Fortunately, Rainbow is able to hear what's going on ...
* RevisedEnding: Originally, [[spoiler:the Pegasi ended up as an OfficialCouple]] by the end of ''Spellbound''. After readers expressed their concern about the circumstances behind this, however, Saddlesoap Opera went back and tweaked the story so that [[spoiler:Dash admits she was under the influence and Fluttershy accepts that, returning to a strong friendship]].
* RevengeBeforeReason: Trixie's need to get payback for "Boast Busters" leads her to steal from Celestia and halfway kill herself using an EmpathicWeapon that backfires on her with nearly lethal results.
* RevengeByProxy: Unable to direct her full anger at her sister [[spoiler:thanks to her Mantle preventing it]], Luna instead gleefully steps up to break the AwfulTruth to her perceived replacement Twilight.
* SecretKeeper: Rainbow Dash becomes one for Pinkie Pie, and Twilight for Rarity, both against their will.
** ''Muffins'' reveals that Rarity knows about Ditzy [[spoiler:dyeing her mane blonde]], and [[spoiler:Ditzy becomes one for The Doctor]].
* SpeechImpediment: ''Muffins'' introduces a griffon with a cracked beak, giving him a permanent lisp.
* StepfordSmiler: Pinkie Pie.
* TallPoppySyndrome: According to ''Loss'', Rarity lives in constant fear of this, which is why [[spoiler: she's generous to the point of driving herself deep into debt.]]
* TarotMotifs: Celestia uses one combined with a ThemedTarotDeck to give Twilight greater insight into her friends [[spoiler:and explain how to help them]].
* ThereAreNoTherapists: According to ''Spellbound'', it seems [[spoiler:the Magic-bearer's role is to play psychologist and keep the other bearers from going insane]].
* WrittenByTheWinners: In ''Alicorns: Blame'', it's revealed that Luna wasn't banished for trying to make the night last forever…Instead, it was because [[spoiler:she made the Everfree Forest ''free'', with all the beauty and horror of nature unleashed]].
* VoodooShark: The idea that [[spoiler: the Elements of Harmony drives the bearers mad only affects Applejack. The rest are explained by outside sources (Fluttershy's problem is hereditary, for instance), and it comes off as something Luna made up to hurt Twilight.]]
** One could argue otherwise. [[spoiler:Rarity, who has the Element of Generosity, became so generous to the point of suffering massive debts, out of a fear of being rejected if she stopped putting others' needs ahead of her own. It's possible that her Element somehow made her think that, or made an already-existing fear into a bigger deal than it actually was. Pinkie, having Laughter, puts on a StepfordSmiler act even when she's not in the mood to laugh at all. Again, it's possible that her Element had something to do with her depression.]]
*** WordOfGod has stated [[spoiler: Luna did make it up.]]
** The more you think about [[spoiler:Celestia's mantle as a mind-control device]], the less sense it makes.

-->[[spoiler:'''Screwball:''']] "You Screwheads are all the same; underestimating the big, dumb Mudhooves who grow your food and pull your carts and take out your trash. Well, Buzzards mighta got the wings, and you mighta got the horns, but we…GOT EVERYTHING ELSE!"
