I believe i already covered this, though.
Do it tbh, L really should be Supergenius with this kinds of feat, which he is not on his profile
No thanks lol, i'm good, it's like 6 am and i havent sleep yet, I almost finished for my defense thesis slides too, but thanks for the fun discussion anyway
Even granting the stock market feat at its highest interpretation, all you've established is that L possesses extraordinary financial cognition. You haven't demonstrated that this cognition arose specifically from superior Learning Ability rather than intuition, reasoning, or narrative fluff. More importantly, you haven't shown why a single domain-specific feat should scale every subcategory of Learning Ability, nor why that translates into a decisive advantage in chess. You're treating an extraordinary outcome as proof of an extraordinary learning process and then generalizing that process to every cognitive domain. That's an inference stacked on top of another inference
And as others said it's barely a EG feat let alone in the realm of supergenius
basically this is just a poorly conceived attempt to wank L's narrative from a vauge feat with limited if any connection to learning ability in how it was presented
I still got Koji. My issue isn't even with the stock market feat itself, it's with how you're scaling it.
You're treating the 20,000× return as if it automatically proves every cognitive process behind it. That's a non sequitur. The feat establishes the outcome, not the exact mechanism that produced it.
Even if we grant L genuinely achieved those returns through his own intellect, that only proves he achieved an absurd financial result. It doesn't automatically prove supernatural intuition, prediction, mental models, application. Those are separate claims that each require their own evidence.
Your reasoning is essentially:
Impossible returns → impossible understanding → supernatural intuition/pattern recognition → predicts every chess move.
Every arrow there is an inference, not something established by the manga.
Then you bootstrap L's Kira deductions to justify the stock feat, and use the stock feat to justify chess. That's circular. His detective feats certainly support deduction and pattern recognition, but they don't suddenly validate "hyper-accurate financial intuition" or "instant chess prediction."
More importantly, chess isn't won by having one absurd feat in a completely different domain. Chess depends on calculation, board visualization, opening knowledge, positional evaluation, tactical accuracy, endgame technique, and practical experience. You haven't shown why an unexplained stock feat grants superiority in those areas.
So until you establish the actual cognitive mechanism behind the stock feat(gl with that) instead of reverse-engineering it from the result, I don't think it justifies giving L an overwhelming Learning Ability advantage, let alone saying he no-diffs Koji in chess.
And I don't think it comes close to koji
Koji's knowledge had surpassed all the White Room Instructors in their chosen fields by age 11. To a degree that trivialized their own understanding as "superficial" in the words of Suzukake who was the head researcher. These same instructors who were compared to the same level as Olympic coaches and were capable of representing the world stage with their talents. This means that Ayanokouji trivializes people who are at the top of their fields and are "world-class" level intellects in their own specialty, but he does this for ALL subjects not just 1. This vastly surpasses L who neither has any feats or statements of reaching this level of knowledge in even 1 subject, let alone every field of study. Furthermore, this certainly does reach the level beyond just unrealistic as while real world polymaths exist, none have come close to this level of understanding and certainly not across all subjects. Then the fact that Koji did this by age 11 only makes it more impressive.
Then from an LA perspective Koji went from learning to read/write starting at age 3 to then learning university level subjects at age 5 so in that 2 year timeframe he learned more than most people learn through college. So yeah, L doesn't even come remotely close here.
So ye I'm voting koji
And let's move on from LA and discuss foresight etc as that would be more engaging
