Why who's the smartest total drama character is such a complicated question and how it can totally be used in fics.
So starting with the OG cast. I've mentioned this briefly in the danganronpaxtd fic (which will be getting an update within the next two weeks, it depends solely on when I'm able to get the last request finished and the loser honey chapter out) but the use of IQs in TD is so silly.
Because there are only three stated IQs, Alejandro's at 163, Noah's at 180, and Izzy (as brainzilla) at 188. So clearly there's an exact hierarchy here, right? Wrong
So first things first, IQs are not typically given precise values outside of 160 because it's a curve based on averages and an IQ higher than 160 is so rare that there is not enough data to compare them and therefore find an accurate value.
Essentially, an IQ above 160 is not reliable or scientifically accurate, it's a guess.
And then that's not including the fact that we don't know what IQ test they did, there are multiple standardised tests all of which have different IQ numbers that are actually the same. Like a 148 on one could be a 130 or 132 on another.
But let's say that sure, they are accurate, neither of the three are lying about their IQs, and they all took the same test.
The difference of 180 and 188 on the IQ scale is basically neglible. The point system in IQ tests vary with some being different questions having different point values (like on a scale of 0-3) and others getting assigned additional points based on the speed they answered a question. So that makes it around a three question difference. Now, if you're already up there to the levels of genius and getting high enough that you clearly understand and are recognising the patterns, three questions are basically nothing. Especially if they're getting basically all of them correct. All it takes is having a headache on the wrong day and that could make such a difference.
And that's another thing, IQ results can change by a 5-15 point marginal depending on the circumstances around the person testing, they might have had a bad day and done ten points worse then what they would have if everything was going right. Some even get much more like a 20 point difference. Once again, because this is a bell curve, we're focusing on the top end (far less than 1%) and the difference between 180 and 188 is so small, you literally cannot say for certain.
Now, if we apply this to all three of them with 15 as the range (even though it is rarer than 10 which is far more likely) then they all have potential varied IQ ranges:
So Alejandro and Izzy have a 16% chance of sharing an IQ, Alejandro and Noah have a 43% chance and Izzy and Noah have a whopping 73%. But once again this is just with the extremes, if it was on average then Alejandro would be nowhere near close to Izzy and only a 15% chance of sharing an IQ with Noah.
Meanwhile Izzy and Noah still have a significantly higher chance (60%) of sharing an IQ or shifting who's smarter.
Their stated IQs are high enough that out of the three of them, Alejandro's is the most reliable being closer to the cut off and Izzy and Noah's are the least and most likely to vary. They could have a higher IQ than the test suggests, or they could have a lower one.
Which could be interesting with the Noah and Izzy dynamics, both of them having similar thought processes but Noah not liking that or acknowledging they're so similar minded/she's the closest thing to his level causing him to lash out and project by calling her crazy constantly. And then there's the fact that based on their scenes in WT they are clearly good friends who respect each other and chances are it's because of this similar intelligence. Both Izzy and Noah canonically get annoyed at people dumber than them after all.
So IQ is out, but what about their social perception and being able to identify things about people? Let's look at their perception skills and how they compare. Except we can't, not really. Both Izzy and Noah screw the data. And that is an incredibly important and recurring point when it comes to the comparison of intelligence. Neither Izzy or Noah are trustworthy sources. Izzy is unpredictable and likes to lie, Noah doesn't like putting in the effort or lasts long enough to display it. Even the intelligent based challenge he competed in tested the intelligence least of them all.
But still, let's have a look.
First Izzy. She notices the Mal thing at first glance. Aaaaand that's about it. She falls for Justin and Alejandro, she doesn't seem to click onto anyone being manipulative. But then again she doesn't seem constantly completely fall for it. It is established that Izzy is willing to go along with something if she finds it entertaining enough so who's to say that doesn't go with the more manipulative contestants? Although she is the only contestant who is consistently able to get various reactions out of Noah so she must be able to read him well enough to tell what affects him.
And for Noah, he was obviously one of the first people to dislike Justin and that was before they found out he could be manipulative, and he's probably the only contestant who remained on bad terms with Duncan and refused to budge on that which could be said that he recognised Duncan was just a bad guy all around.
Plus we don't know when he first clocked onto Alejandro. Usually when this would happen with other contestants, they would have a confessional talking about how suspicious they are about another person or how they worked it out. Not Noah. All he got was warning the other contestants. You could say that he only noticed in Germany, but that was less him working it out and more him getting annoyed that Alejandro was throwing challenges. So he could have known since the first episode and just never said it out loud. Once again, we don't know because of the confessionals and Noah's lack of presence in the show.
Alejandro is also complicated because he does work out the Duncan Gwen thing after seeing Tyler's odd behaviour and the song between the two.
But then for a supposedly intelligent and perceptive character he finds out about Noah not trusting him (a teammate he spends the most time with in the background) through Noah out right stating it to his teammates and Chris letting him see it via the cameras. Based on his shocked and angry reaction, he wouldn't have picked up on it if Noah didn't outright say it or it wasn't shown on camera. The important part of this is that Noah figured him out, he did not figure Noah out. Noah had a better read on him then he did on him.
Same with Mal, he worked it out after coming across the confessionals and watching them. In neither of those instances did Alejandro come to his own conclusion on what was going on instead he was handfed the information and he didn't have an intellect based strategy, it was solely seduction based. So while Alejandro hasn't been put in a direct battle of wits thanks to his tactics, the closest comes to Noah which arguably ended in Noah's favour. He may have been eliminated but he won in the ways that mattered.
So with this being the only point of competition between the two (the elimination itself doesn't count because that was pure luck on Alejandro's side, they should've won the challenge and they just so happened to gain a teammate with an antagonistic relationship with Noah), Noah appears to be superior in intelligence. Once again though, it's not certain, there's not enough for a true comparison.
And if we're keeping with this theme then Izzy is more perceptive than Alejandro because she clocked Mal faster than he did. Though that does beg the question, how fast would Noah have if he had met Mike and Mal?
But yeah, Izzy and Noah's perceptiveness are mainly from their own personal experience and conclusions whereas Alejandro is from information given to him outside of it
If you add the female Noah thing to this then all it does is strengthen the point lmao, Noah and Izzy have a better chance at deceiving him than the other way around.
Intelligent contestants over all
So ig we can rule Alejandro out, or at the very least put him to the side for now. Which leaves Noah, Izzy, B, Cameron and Scarlett as the notably most intelligent in their cast list.
Except that there's literally no frame of comparison. Sure we could use IQs although that'd have a high chance of inaccuracies, but only two of these characters have a canon IQ which really do have a neglible difference.
Then what about the capabilities of these contestants? We can't use that either, for starters intelligence can be displayed differently in each person and none of them have taken any test that could have compared them on that front. Well, Izzy was quizzed but the other four weren't.
What we do know is that Izzy and Noah have incredibly similar IQs, that Scarlett is supposed to be the female version of Cameron without the bubble so their intelligence has to be on par with each other, and that B has no direct comparison. But between the two pairs, the only two of that interact cross-season are Cam and Izzy with neither of them doing anything that could compare their intelligence.
If they did and Izzy came out on top, then she's smarter than both Cam and Scarlett and the chances are that so is Noah. B is unknown. If Cam came out on top then he should be smarter than Izzy and Noah, but he'd have no way to know if Izzy was genuinely trying or if Noah is actually less intelligent than Izzy. B still remains unknown.
And that's the key part of their characters, Cameron, Scarlett, and B all try in the competition so their abilities are shown off. Neither Izzy or Noah try enough in the competition- or care for that matter- so we don't see their abilities. That's what sets the two groups apart.
So what's the closest we have for a comparison? Technology.
Except we can't use that either. We don't know what Noah's current skills are since we don't see him interact with technology in any way (which the area 51 challenge could have shown us) during the seasons. He wasn't given the same chance as those three to shine with what he knows best. Even Izzy didn't get to, but she did say she worked out the formula for time travel.
Alongside building technology and using mechanical prowess, B, Cameron and Scarlett have all used coding on the show. Scarlett also mentioned programming toys to pull her brothers hair for six years, but at no point is her age for that mentioned. The oldest she would have been is 10/11 which is still certainly an impressive feat, and we don't know what the youngest is.
Izzy and Noah aren't shown coding in the show. However, we know that Noah was able to hack into websites/forums when he was six and got a job from it. Now logically that would mean that he must have good skills with coding and implies he had an interest in technology. One that could have been explored and studied heavily in the ten year gap.
But that was at the age of six, we don't know what he is capable of now or what he was at that age. Was his ability back then on the same level as Cameron and Scarlett's are now and he's long surpassed them? Or was he less advanced? Could he now, is he at that level or long surpass it? Could he build the stuff they could at any point in his life?
What was Scarlett capable of at the age of six? Or Izzy? Or Cameron? Or B?
You literally can't compare them. Though I suppose that the two with the named IQs tried the least in the competition and were more focused on gags and snarking people. Especially if you believe the Noah self eliminated and Izzy is pretending to be crazy headcanons.
And it's because of all of this that we can't measure up the intelligence of the most intelligent people in each season. You cannot correctly assume who the most intelligent TD character is, so when it comes to fanfics and aus any of them can be more intelligent than the others.
So more people should make use of this imo. Like imagine Noah being a mentor figure to Cameron, like an online tutor or something before TD and he taught Cameron everything he knew about technology- compared to Izzy who he's scared of. Or Izzy and Noah mentoring B. Or Izzy Noah and Cameron being able to immediately (or almost immediately) pick up on Scarlett faking her personality.
Or in highschool aus where all of them are years ahead of their cast mates and instead interact with older characters.
They'd all probably pick up on whatever the others are hiding. Bonus points for femnoah and they are the only people out of the entire cast who work it out.
Hell, including Alejandro I offer to you all six of them interacting together at full brain capacity, that would be stupidly interesting. Alejandro would be outsmarted tho and humbled from it.
So then, what are your thoughts on this? If you had to rank them how would you and who would be the most to least intelligent of the group?
