Not to mention, Palpatine was smart enough to figure out how to destroy the Jedi and the republic in one fell swoop. Sidious' IQ therefore is most definitely in the top 0.1% at least. His IQ I would say is +160, but there is no real way to know for sure.
Yoda: 180 - 190. Anakin: 165 - 170. Count Dooku: 160 - 165. Revan: 160. Mace Windu: 155.
However, Palpatine is more knowledgeable on politics, The Force, and how to manipulate people. He knows how to remain undetected and run an underground criminal organization while keeping his hands clean, as well as how to clone his body and transfer his life essence into the new version of his body.
Master Tactician: Even before his fall to the dark side, Vader was amazingly intelligent and wise. Darth Vader was a brilliant strategist and was still, despite his lessened Force potential, one of the greatest pilots in the galaxy.
If it came to strategic prowess then most likely you'd find Sidious ahead. He was the one after all who managed to outsmart the entirety of the Jedi Order and Republic (minus the few individuals aiding him). And was then smart enough to keep any rivals in line or at a distance during his reign as emperor.
Star Wars fans adore Darth Nihilus, and for good reason. His skeletal-like mask and dark robe make for an iconic Sith, yet it's his brutality, ruthlessness, and immense power that make Nihilus a fan favorite.
Anakin: 165 - 170. Count Dooku: 160 - 165. Revan: 160. Mace Windu: 155.
Yoda was a legendary Jedi Master and stronger than most in his connection with the Force. Small in size but wise and powerful, he trained Jedi for over 800 years, playing integral roles in the Clone Wars, the instruction of Luke Skywalker, and unlocking the path to immortality.
1 Luke Skywalker
Having faced his father once before, Luke was familiar with his tactics and used the force to gain an upper-hand. In Star Wars Canon, only Luke Skywalker can be acknowledged as the one who truly defeated Darth Vader.
Genius-Level Intellect/Master Tactician/Leader: Being over eight hundred years old, Yoda is amazingly intelligent and wise. As a Jedi General and leader of the Jedi Order, Yoda is a highly skilled tactician and a very capable leader.
Sidious ultimately prevailed though. He dueled Yoda evenly in the senate, but only defeated Yoda using his overwhelming force powers. Darth Vader: Second most powerful Sith Lord ever, behind Sidious only.
70 to 84: Borderline mental disability. 85 to 114: Average intelligence. 115 to 129: Above average or bright. 130 to 144: Moderately gifted.
Qui-Gon Jinn, a Force-sensitive human male, was a venerable if maverick Jedi Master who lived during the last years of the Republic Era. He was a wise and well-respected member of the Jedi Order, and was offered a seat on the Jedi Council, but chose to reject and follow his own path.
#1 – Yoda. Yoda is widely considered to be the greatest Jedi of all time, and with good reason. He is a master of the Force, a skilled warrior, and has an unmatched wisdom that comes from centuries of experience.
Arguably, some of the rarest types of Jedi were the so-called Iron Knights. These are members of the Shards species - crystals with a brain of their own.
Obi-Wan Kenobi
Through it all, Obi-Wan reveals himself to be one of the very best examples of what a Jedi Knight should be: selfless, kind, and willing to do whatever it takes to protect those in need.
Canon has established that Anakin, while brilliant, has a very flighty attention span and unless it's something that is deeply important to him or made glaringly obvious, his brain has a tendency to skip over it, and makes him less aware. Anakin and HYPERFOCUS: The flip side of ADHD focus issues.
Most people have an average IQ between 85 and 115. Overall, about 98% of people have a score below 130.
Princess Leia is certainly the most intelligent character within the Skywalker family, which is clear from the start. Leia is someone who always thinks before she acts, and has a response to any situation or comment from other characters, which is a lot of fun to see.
Darth Sidious, also known as the Emperor and Supreme Chancellor Palpatine, is not just the evilest Sith in Star Wars (arguably in both canon and Legends) but the evilest villain overall, deemed so thanks to his irredeemable actions throughout the Skywalker saga and surrounding content.
A Sith Lord with the ability to cheat death and create life, Plagueis is the mentor of Sheev Palpatine / Darth Sidious, who, in accordance to the Sith's Rule of Two, eventually betrays Plagueis by murdering him in his sleep, taking his place as Sith Master.
As the first Dark Lord of the Sith, Ajunta Pall founded the first Sith Empire and expanded it onto other worlds. The Sith took over the planet Ziost and created it as their capital and as Pall's new home.
