TENETS

be polite and chill
scaling is not that serious don't get heated

be in good faith no toxicity allowed

focus on your favs

A guide on categories used in the scaling and distribution in who' outsmarts / who's smarter etc

(see check comments reddit is flagging the post due to the links)

SCD scaling categories

II. SCD scaling Categories

Detailed Explanation Of SCD Categories

DAX PMFT'S SCALING GUIDE (including explanation of diffs and pre made distribution system**)

Dax's scaling model explained

(categories =/= characterize. That's why situations & scenarios are included where characters are placed sometimes, though it requires knowing the characterization and personality.

advice - don't give certain takes on something you don't know about, and avoid absolute certainty, as there is no such thing, especially in fiction.

However, remember this quote: "Who decided that smart people are categorically superior?" (quote from one series)

remember to know what kind of character type (planner, XYZ merchants , behind the curtain  it is; some characters thrive in the long game/term only)

Frequent used distribution system

feel free to create your own dist also

Explanation of "DIFFS ,"DIFFED"  and "TIERS":

note: no low diff and neg diff are possible unless there's a 3-tier gap, but at that point you're using a spite matchup

Diffs - characters wins by points in matchup

Diffed - other character loss by points in matchup

(+- Implies the difficulty could be higher than what is estimated.)
(-) - Implies the difficulty could be lower than what is estimated.

~ A Beginners Guide to Tiers: What they mean and what the defining characteristics between tiers are

\ tiers are arbitrary. there are times when a character cannot be placed into a tier for various reasons, such as differences, etc.)

\for that, tiers are relative and exist in correlation with a specific thing. however, having an idea of F to S+ and low to top-tier comparisons gives a general framework to map things and establish a general consensus.)

Scaling system ,situations etc

Explanation and role of  narrative , feats and anti-feats in the scaling and matchup

Feats : Things and notable actions the character implicitly or explicitly demonstrated/accomplished.

Anti-feats : blunders by characters . two types - impediment or non impediment

Statements: Explicit claims regarding a character's intelligence, abilities, accomplishments, reputation, or capabilities.

Statements should be considered alongside their context, reliability, and consistency with the character's actual portrayal.

Methods/Processes:   "how " a character/feat achieves a result. it's about the pathology of the formulation and the steps of the feat rather than just the outcome

Narrative: The broader portrayal of a character through the story.

Narrative should be properly read and discerned rather than treated as an automatic substitute for feats. It can include recurring portrayal, characterization, comparisons, thematic framing, consistency, and the character's established role within the story.

Narrative isn't some magical excuse to scale a character higher than their feats, nor is it something that should automatically be dismissed because it isn't a direct feat.

\narrative word is literally the bogeyman for scaling/scalers for some reason. like read properly and discern)

READ .THE NARRATIVE. PROPERLY.

also narrative is called story-wise.

Ability: What the character is capable of doing, demonstrated or established through feats, methods/processes, statements, narrative, etc.

ability is not necessarily the same as what a character consistently performs in every situation.

if only methods and feats are taken into account  then it's proven ability aka establish ability basically a rigorous way of judging ability expecting to to work consistently.

Outsmarting Situations:The specific circumstances in which a character's intelligence is being tested.

SCALING SYSTEM:

word of advice - don't scale any fear/character in isolation & independence  ; scale rather taking account of continuity and sequence of events. ask "is the character doing something logical to their past, character and environment or not?"

normal scaling (default system): taking everything into account, including anti-feats, feats, abilities, methods etc.

note: normal =/= narrative

non normal scaling  :

  • stop scaling - only explicit, explainable feats with steps/steps that can be derived
  • pure methodology - significant focus on rigour and steps
  • methodology scaling - focus on the process/method of a feat, either implicit or explicit

(other methods are mostly neurodivergent or neurotic)

normal + non-normal scaling:

  1. Complete Scaling Method
  2. Dynamic Gauntlet system
  3. any scaling that measures a character holistically

(except any scaling that invalidates a character for any reason, including "objectivity")

OUTSMARTING SITUATIONS:

The Fixed Situation (FS) - fixed rules and variables

The Non-Fixed Situation (NFS) - non-fixed rules and variables

The Cat and Mouse Chase Situation(C&M)

  • as the cat(: cat)
  • as the rat(:rat)

Reference Series

These series are mostly familiar within SCD on a broad and overall level. They make up a lot of the commonly used reading/scaling material in SCD. The main reference pool is Classroom of the elite, Tomodachi Game, Death Note (the big three ), Liar Game, Usogui, and Monster, while Code Geass, The Mentalist, and Danganronpa are used more occasionally or as supplementary references.

The reference pool and its series have characters across many different tiers and levels, making them useful for comparing and scaling characters against each other.

Familiarity here generally means broad knowledge of the series and its SCD-relevant material, rather than knowing every feat or interpretation in depth.

Reasons why I'm referring to TG, COTE, and DN  as the  big three are:

First, popularity and starters of SCD.

Second, all three are digestible and diegetic. COTE has digestible and diegetic hierarchy & dynamic of smart characters, TG has digestible and diegetic games & mind games, and DN has diegetic and digestible opposition and difficulty.

In other words, these series don't just have characters who are called smart. Their stories diegetically demonstrate and establish intelligence through games, conflicts, hierarchies, opposition, strategies, and interactions between characters.

This makes TG, COTE, and DN useful starting points for newer people to center themselves around when learning SCD. They provide recognizable examples of different types of intelligence and outsmarting while also giving people material that can be directly examined and scaled.

Plus, most people already have a general understanding of these series and characters, making it easier to learn by “osmosis” — you don't necessarily need to read the entire series yourself to have a basic understanding of the characters, their feats, and their general scaling.

This doesn't mean these three series are inherently superior to everything else. They're being used primarily because of their popularity, familiarity, diegetic material, and usefulness as reference points.

USEFUL THINGS

One useful thing you can make for SCD is a 3×3 grid showing a character’s strongest categories or suits. You can make one easily by using any 3×3 grid template in Canva and replacing the images with your own. Alternatively, you can attach nine images to Gemini or ChatGPT, provide the nine categories you want represented, and ask it to arrange them into a 3×3 grid.

For fanart, Pinterest is a convenient place to find images. Simply search for the character you want and save a piece of art that fits your edit. Safebooru is another useful alternative for finding character artwork. Always credit and source the artist when using someone else’s artwork.

For tier lists, you can use any tier-list-making site, or use the SCD-specific TierMaker template.

Finally, pixel conversion is completely optional and is mainly useful for aesthetics. You can convert an image into a pixel-art style using the Sora Pixel Converter.

actually scaling intelligence Short analysis of Netora Reiko's manipulation of Shirase Yuri

Post image
12 Upvotes

(The manga is Reincarnated Beauty Netora Reiko and this feat happens in chapter 2)

So while Netora Reiko and her childhood friend Yuu are seeing which clubs they should join, they open the library to check out the literature club and Yuri Shirase, one of its members, is surprised by their sudden entrance and slips, with a ton of books crashing onto her

After they help her out, Reiko (who knew from earlier that Yuri is a lesbian due to the way she stared at Reiko in class) gets up close and stares at her for a moment, making Yuri feel awkward. Reiko then asks if she is Yuri Shirase from her class, which Yuri confirms and says that she's surprised that Reiko knows her name to which Reiko replies saying that it's only natural since they're classmates

Reiko then asks Yuri about the literature club and bons with her over their shared love of books. Reiko mentions how she's wanted to talk to Yuri more, to which Yuri responds by saying that she also wanted to talk with Reiko more. Reiko then "remembers" that the books that fell on Yuri were quite heavy and shows a more kind and caring side, checking Yuri's head for injuries which was actually just so Yuri would see Reiko's chest up close which is meant to serve as direct form of seduction

After confirming that Yuri's head is fine, she asks her if they can join the literature club (referring to her as "Yuri-chan" instead of "Shirase-san" like earlier, which is a more intimate way to refer to someone)

After Yuri explains how to get the form submitted so they can join the literature club, Reiko once again calls her Yuri-chan and hugs her a thankful gesture for helping them out, once again expanding the intimate bond she created. When Yuu-kun points out how Reiko's being a bit too touchy with Yuri, Reiko says that this is perfectly normal for girls and then whispers to Yuri that since it's perfectly normal, she doesn't have to hold back. This creates the idea in Yuri's mind that this quickly-created and intimate bond between Reiko and Yuri is completely normal

Reiko then leaves and says they'll see each other tomorrow

So in summary, Reiko within minutes creates and then gradually builds an intimate bond with Yuri. First starting by telling Yuri that she knows her from her class which is an effective way to seduce her as Yuri's shyness would make it so she'd feel really happy about her crush recognizing her, then Reiko starts talking about their common interest, then showing a more caring side towards Yuri by checking for head injuries, at the same time she's making Yuri feel aroused by being so close to Reiko's chest, then starting to call her Yuri-chan as a way to clearly show a more intimate bond between them, then thanking her and hugging her which once again builds a more intimate bond and then finally she tops it off by convincing Yuri that their intimate bond is completely normal

actually scaling intelligence Gwyn's Universal Origin Deduction

Post image
8 Upvotes

Gwyn is shown visualizing the universe itself, with numbers, equations, and mathematical structures forming around him as he instantly deduces the origin of the universe.

To accomplish this, Gwyn would first have to reduce Reality itself into quantifiable inputs, such things including:

  • Energy distributions.
  • Space-time curvature.
  • Causality chains.
  • Conservation laws.
  • Symmetry and asymmetry.

He would then have to identify the fundamental invariants and constraints governing these variables, including conservation of energy, mathematical symmetry, dimensional consistency, and information preservation, determining which principles apply throughout the universe's evolution.

From there, Gwyn would work backward numerically, using the universe's current expansion and observable properties to reconstruct its earlier states.

He would repeatedly test the resulting equations, eliminating solutions that violate stability, continuity, or logical consistency until only mathematically viable origins remain.

However, he would also have to investigate the concept of "before time." Rather than treating time as a pre-existing constant, he would represent it as a variable or boundary condition, solving equations in which time emerges as a result rather than being assumed as a cause.

Afterward, Gwyn would investigate the fundamental conditions of an origin by examining a hypothetical state in which:

  • Energy = 0
  • Information = 0
  • Structure = 0

If absolute nothingness existed in the strictest sense, nothing could simply begin without an explanation for how existence emerged.

Therefore, Gwyn would have to determine whether the universe originated from a fluctuation, a necessity, or an unavoidable mathematical consequence, and establish which possibility could be supported by the mathematical framework.

He would then visualize all these equations and relationships simultaneously, treating constants, variables, and their interactions as shapes and motions within his mind. (As he visualizes all of the calculations that he makes, which is shown on multiple occasions—like the one above)

By comparing the possibilities against the constraints he had established, he would narrow them down to a class of origins that does not violate the applicable conservation laws, explains cosmic expansion, allows complexity to emerge, accommodates the emergence of time, and remains internally consistent.

Finally, because all of this is shown in a flashback, Gwyn must have already encoded the entire mathematical model into his memory.

He visualizes the universe beforehand, retains the underlying relationships rather than merely memorizing the conclusions, and can re-derive the results instantaneously.

Tier List Tierlist based on the anhs&wr system { read post before attacking}

Post image
18 Upvotes

Before you attack, look, there's a trend of increasing smartness in tier lists based solely on ANHS and WR. That was the main idea behind this tier list.

Classes A–D are more about personality and proven ability (PA) than purely about intelligence. For example, if a character has good PA but is very self-centered (SC), they might be placed in Class D. Conversely, a character with low PA but a selfless personality might be placed in Class A. Or, in some cases, they're just bums.

light is season 1 (without hax and equalised )

Akane is considered for Game 1 only. (Though I've heard she's a victim of Kushida without haxs and without theories.)

Consider the class leaders and class representatives as duos or trios representing the four classes.

All characters in this tier list are considered in their young adult (YA) versions. Their childhood versions were not considered.

THIS IS MORE OF A FUN TIER LIST THAN A FUNCTIONAL SCD TIER LIST, SO PLEASE DON'T BE OFFENDED BY THE PLACEMENTS!

Suggest new characters for placement or changes to existing placements in the comments.

low effort Missing Abdomen - A Short Kanade Feat

6 Upvotes

This post will cover a short tactic that Kanade used in chapter 3. Specifically, her removal of the abdomen from Setsuka's corpse.

In case anyone is unfamiliar with this case, the surface level reason that she did this was to hide the stab wounds. Kanade and Hibiki performed a double murder by stabbing Setsuka simultaneously in the abdomen. The main reason that this was necessary was that Kanade and Hibiki are left and right handed respectively, and this would allow a skilled detective to determine that the two stab wounds came from two different killers. Her removal and discarding of the abdomen conceals this entirely. However, after closer analysis she also had several other reasons and intertwining tactics to do this.

This tactic ties directly into the Iroha framing; from the detective's position, it is clear that the culprit had a reason to remove the abdomen. Kanade correctly predicts that Shobai will postulate the reason as the killer hiding their dominant hand. Why would a killer need to hide their dominant hand? The obvious reason is that there are far fewer left handed people than right handed people. In the SDRA2 cast, only Iroha and Kanade are left handed, immediately making them potential culprits, assuming the previous reasoning is correct.

As we know, Kanade goes on to framing Iroha later in the trial after Shobai makes this deduction, using this piece of evidence as a very strong and convincing premise to pile onto what was already a good plan.

Now, what about the fact that she made herself a suspect? This was also entirely planned. Kanade even leaks other details that put her on Shobai's radar, namely mentioning how she is aware of Hibiki's trauma induced memory loss. Kanade had purposely set things up so that it is extremely difficult to line up the events that would result in her involvement to the murder. In other words, if she was accused it would be almost impossible to pinpoint how she was able to do it. As predicted, Shobai's reasoning falls short. Shortly after, she is able to use basically the exact same premises that Shobai outlined to successfully incriminate the other suspect created by the abdomen's removal: Iroha.

Probably the funniest part about this feat is the fact that while it does arouse suspicious towards certain people effectively, it isn't even close to definitive evidence. There are countless other reasons for the abdomen's removal. This is important because it means that if Kanade's plan to frame Iroha fails, the removal doesn't necessarily incriminate her either.

Even if Shobai never accused Kanade for some reason, this still leaves no evidence pointing towards her.

Just for the extra slight wank, we can also detail how this ties into the logistics of the murder plan. Deep into the plan, Hibiki is required to sprint a medium distance while carrying the torso in as little time as possible.

Doing some quick google searches we can attain some useful info (I hope I don't get put on a registry for this). If Hibiki were to carry her entire torso (thorax+abdomen) then that would be around 29% of Setsuka's bodyweight, which comes out to around 16kgs or 35lbs. Without the torso, this is reduced to 17% of Setsuka's bodyweight which is approximately 9kgs or 21lbs. In other words, Hibiki would likely be able to sprint much faster than with the entire torso intact. The reasons for her speed needing to be that high are a bit beyond the scope of this post, in short Kanade needed this time interval to be as short as possible in order to clear herself of suspicion.

In SCD terms, this fulfills a decent amount of deception categories on its own. Uses EU/EP/ToM/logical manipulation to utilize Shobai's knowledge and background against him. Strategy logistics and foresight for the last part.

Even knowing to remove the abdomen proves she knew the effects of this action on Shobai's inference, alongside purposely choosing Iroha as her framing target. If she didn't consider this, she could've picked Nikei or Teruya to frame because of their hat/baggy clothes.

I mostly made this post for fun, I could see myself making some similar ones in the future depending on how this one is received. I personally think that Kanade is underrated in this sub and hopefully that can change in the future 🙏. Let me know if I left out anything crucial I made this kinda fast

Here’s what I’m wondering: suppose character X has implemented their strategy X, and character Y intended to implement counterstrategy Y vs strategy X, but X predicted this intention and therefore implemented counterstrategy X vs counterstrategy Y even before implementation of counterstrategy Y, thereby aligning counterstrategy X with strategy X. Would this strategy X + counterstrategy X be considered as one strategy, or two different strategies, or it's both?

Made a New headcanon, Meet Baku Madarame (Plan Theory)! Made with help of a friend who had connections to Axol (who has Baku and Fyodor relative in SCD).
Basically, this interpretation says that Baku orchestrated the entirety of Usogui. That it was his plan along to bring a wildcard (Kaji). That every death in Usogui was calculated beforehand. That every event was foreseen. That the events in STL were all Baku's plan. That giving his heart to Gonen was Baku's plan. That conquering Ideal, Kakerou and Vices were all Baku's plan from day one.

Why is it not humanly possible? Is it because of limitations of human biology? Also how much of intelligence do you think is biological? And how trainable is the liquid part? Most feats I've seen seemed like they're not caused by crystallized intelligence. So what really makes it impossible?
