He was believed to have an IQ over 200 by his teacher, Asuma, and could defeat opponents significantly stronger than he was, provided there was even the slightest chance of victory. He is highly observant and is so intelligent that he is capable of staying ten steps ahead of an average opponent.
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.
Naruto is no exception to this. 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.
Over 200. Asuma stated that Shikamaru had an IQ of 200 plus, and since then we've had two quotes verifying that Kakashi is above that.
Alright, first, let's address the basics (AKA the canonically-approved facts). In Part I, Shikamaru's IQ is acknowledged as over 200, which is above and beyond genius level (which is approximated at 140). In Part II (Shippuden), Naruto states (and Sakura agrees) that Kakashi is “smarter than Shikamaru”.
1 Shikamaru Nara
He was believed to have an IQ over 200 by his teacher, Asuma, and could defeat opponents significantly stronger than he was, provided there was even the slightest chance of victory.
What is Itachi IQ? Opinion: 160–200 ( 185 ) Itachi's IQ is considered genius level in the naruto verse by his peers. By the time he made anbu, he was 12–13 and later became a captain shortly thereafter.
According to Ukyo Kodachi, Sakura has a rank of 174 in intelligence, right after Shikamaru and before ninja considered geniuses, like Katasuke. Overall, Sakura is a kunoichi known mainly for her intelligence (and chakra control), a feat that is a basis for the kind of ninja she became.
What is Uchiha Madara's IQ? He was believed to have an IQ over 200 by his teacher, Asuma, and could defeat opponents significantly stronger than he was, provided there was even the slightest chance of victory.
Shikamaru Nara & Shikaku Nara
His tactical genius is well expressed during the war, and he also regularly beat his son Shikamaru in Shogi, who himself is an extremely intelligent ninja. Shikamaru, on the other hand, had an IQ of 200 and served as the Allied Forces' chief strategist after his father's demise.
Goku-76, Probably higher than you thought but he often proves he can do smart things too. Vegeta-106, About average intelligence and is never shown to have superior intelligence. Piccolo-115, Often portrayed to have clever moments and leads the Z fighters in a smart way. Bulma-190, No surprise Bulma's REALLY smart.
4 Naruto Wins: He's Smarter Than Goku
He never has to use his brains, which is a special disadvantage seeing how he always begins fights by underestimating his opponents.
Not only was he strong, though, but he was also extremely intelligent too. His knowledge and his drive to bring peace to the planet drove him to the top of the databook rankings. Jiraiya is tied with Itachi Uchiha as having the highest stats total in the official Naruto databook.
Although underrated, Obito Uchiha was one of the most intelligent members of the Akatsuki. He was a master manipulator who took the reigns of the Akatsuki by getting into the head of the Amegakure orphans. He put the Fourth Mizukage under his control and manipulated an entire village all by himself.
Tobirama was the most intelligent Hokage ever to rule the Leaf.
Itachi is arguably the most advanced ninja the Hidden Leaf Village has ever seen. Itachi was a child prodigy and graduated from the Ninja Academy when he was just 7 years old, after being enrolled for less than a year.
Most people have an average IQ between 85 and 115. Overall, about 98% of people have a score below 130.
To calculate IQ, take a person's mental age, divide it by chronological age, then multiply that number by 100. For example, if a person has a mental age of 12 but is 10 years old, then you'd divide 12 by 10, and multiple that number by 100, which would result in an IQ of 120.
He is a highly unenthusiastic person, and he attempts to go through life with minimum effort. Contrary to his lazy tendencies, Shikamaru is extremely intelligent; his teacher, Asuma Sarutobi, determined that Shikamaru's IQ was over 200.
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.
Over the two years that followed, Itachi's physical condition got even worse and his usage of the Mangekyo Sharingan led to blindness as well. This was most apparent during his fight against Sasuke, where he was taking his brother on in combat while being mostly blind yet dominating him.
He's a genius compared to the rest of his class, too, receiving perfect scores on written exams that were so difficult, you were supposed to cheat. So yeah, Boruto's a genius, too. But he pales in comparison to Itachi. Anyone would.
