Of the members of Team Seven, barring Kakashi, we can say that each of them have their own intelligences. As a formality though, the franchise puts Sakura's IQ at 174, Sasuke's at 100 and Naruto's at 90, just below the human average.
Shikamaru Nara & Shikaku Nara
Shikamaru, on the other hand, had an IQ of 200 and served as the Allied Forces' chief strategist after his father's demise.
The only ones that make any sense at all is Naruto's 90 IQ… and Sasuke's 100-110 (even with sasuke, you'd think it would be a little higher). SOME of the only characters I see that surpass an IQ of 160-170 realistically are Minato, Itachi, Kakashi, Kabuto and Orochimaru.
1)Naruto saying that Kakashi is “smarter than Shikamaru” meaning his IQ is over 200, one could say “Well how would Naruto make that determination” this comes down to it being an obvious case of authors intent, the quote was there to build up Kakashi.
In the databook Sakura has an IQ of 175. That's higher than most anime characters.
Based on the universe he's in and the standards set within it, I'd estimate between 130–160. He's a genius but he's also emotionally stunted. He catches on to concepts and observations pretty instantly and can formulate proper responses and apply solutions on a short whim.
William James Sidis has the World's Highest IQ. Anywhere from 250 to 300 is his IQ score, almost twice the score of Albert Einstein. At the age of eleven, William famously entered Harvard University, becoming the youngest person to enter. He also claimed to be conversant in 25 languages.
As a formality though, the franchise puts Sakura's IQ at 174, Sasuke's at 100 and Naruto's at 90, just below the human average.
What's more, Nagato's usage of the Six Paths of Pain was very clever and his arrangement of the various Pains was very tactical. He was smart enough to lure Naruto to places where he held the advantage and was overall a very intelligent character.
Goku: 76, even though you might think his IQ could be even lower sometimes, he often proves he can do some smart things too, especially while fighting and especially during DBZ.
#1 Saiki Kusuo
The smartest character on this entire list, Saiki Kusuo is a step ahead of his jealous brother. Even without the use of his psychic powers, Kusuo would ace any IQ test he took.
Neji is supposed to be a genius and characters like Asuma and Jiraya score a 4.5. While characters like Itachi, Hiruzen, Minato, Shikamaru, etc score a 5. Hidan himself score a 3 higher than Lee, Choji, and probably a few others. Neji the genius scored a 2.5 in original Naruto and a 3 in Naruto.
It has been established that Naruto is not the smartest character in the series and is the type of person who lets his emotions get the better of him. However, he matured quite a bit and displayed his intellect on a few occasions. However, he always consults Shikamaru on matters that require a lot of thinking.
Tobirama was the most intelligent Hokage ever to rule the Leaf. A ninjutsu genius, he created powerful forbidden techniques such as the Edo Tensei and shadow clone jutsu.
According to those who knew him personally, Minato was a very talented ninja prodigy — a rare genius that appeared only once in a generation.
Marilyn vos Savant (/ˌvɒs səˈvɑːnt/; born Marilyn Mach; August 11, 1946) is an American magazine columnist who has the highest recorded intelligence quotient (IQ) in the Guinness Book of Records, a competitive category the publication has since retired.
An average person scores 100 on an IQ test using the Stanford-Binet IQ scale. A score of 137 to 160 is considered the top 1 percent to .
Marilyn vos Savant: 228
Born in 1946 in St. Louis, Missouri, Savant was listed as the person with the highest IQ by Guinness World Records.
Basically the highest in the series. He planned so far ahead, his battle intellect is unrivaled in the series, and he knows things that even Itachi couldn't comprehend. All in all, he's probably one of the smartest characters in the series, if not THE smartest.
By disguising a number of intelligence tests as games and puzzles – the only way Asuma could get Shikamaru to be interested – Asuma discovered that Shikamaru has an IQ of over 200; his poor grades were because he was too lazy to take any of the written exams.
Boruto Uzumaki
Compared to Naruto, who was a perfect knucklehead shinobi, Boruto is much more intelligent.
