Which Character Has The Lowest IQ In Dr. Stone?

When the "Dr. Stone" manga debuted in 2017, fans knew it was only a matter of time until it received an anime adaptation. Those thoughts came to fruition in 2019 when the show premiered, giving access to a wider range of people to watch the exploits of Senku as he attempts to bring the world back into an age of enlightenment after thousands of years have passed, with most of the population having since turned to stone. 

Luckily, Senku's eventually able to get out of his stone prison, which is a very good thing for mankind because he's one of the most intelligent individuals who's ever existed. Tsukasa even refers to him in one episode as being "the sharpest, most intelligent man in the world." Over the course of the series, Senku teams up with other people who have escaped from the rock, and together, they basically have to come up with every invention humanity had prior to the apocalypse. 

Senku's intellect rivals that of Korosensei from "Assassination Classroom" and Light Yagami from one of the best horror anime of all time, "Death Note." Of course, not everyone can be a genius or things would get boring fast, and while there's no official data about who technically has the lowest IQ, we think a lot of "Dr. Stone" fans would agree one character tends to be a little dimmer than the rest.

Taiju values brawn over brain

While no one can really come close to Senku's intelligence, other characters at least get some opportunities to show off their mental acumen. Chrome builds a water wheel for the Kingdom of Science, and Kaseki has proven himself to be a master craftsman. Unfortunately, when it comes to being one fry short of a Happy Meal, Taiju just doesn't appear all that bright. 

That doesn't stop him from being best friends with Senku, and in fact, the partnership proves to be a fruitful endeavor in the way the two play off each other's strengths. Taiju may not fully understand the science Senku tries to explain to him, but he's more than willing to go along with whatever he offers. In return, Taiju is a true force of nature in terms of power, possessing greater brute strength and durability than the average person, which is a major asset in building bridges and things of that ilk. Perhaps because he doesn't tend to overthink anything, Taiju made for the perfect spy within the Tsukasa Empire to help bring it down from within. He got along with everyone, so they were willing to lower their guards when he was around. 

There is some evidence to suggest he's not just playing dumb but actually isn't as smart as everyone else. In a Reddit thread debating characters' intelligence, u/DmtrIV posted a link to a page from the manga, which depicts the main characters' grades while they were still in school. It should come as no surprise to see Taiju at the complete opposite end of the spectrum from Senku.
