Logic

Logic is a skill in The Sims series. It is a valuable skill for many careers and playing games like chess. In The Sims: Makin' Magic, it improves spell casting, affects how many MagiCoins a Sim will get for performing on the stone stage or at the tricks tables in Magic Town, and may affect the performance of other magical acts.

In The Sims 2, logic also affects the odds of winning a chess game. With The Sims 2: University, teenagers with a high logic skill (level 8 or higher) qualify for the Will Wright Genius Grant, which is a §750 scholarship. Logic increases the rate at which a Sim earns the Register talent badge from The Sims 2: Open for Business. With The Sims 2: FreeTime, having high logic makes it easier for Sims to maintain high enthusiasm for the games and science hobbies. Additionally, all Sims in The Sims 2 who have 10 points in logic get a 35% boost when learning other skills, except for body and charisma.

Abilities
Increasing a Sim's logic skill gives the Sim certain special interactions:

Celestial bodies
When using a telescope and searching the galaxy, a Sim will sometimes discover a celestial body. It may be a comet, planet, star, moon, galaxy, black hole, neutron or satellite. The Sim will then earn a small amount of money or up to several thousand (for discovering a black hole) for contributing to the scientific community.

Also, Sims may see a meteor fall from the sky and land somewhere in town. They can use Map View to find the land site and travel there to collect the space rock. There is also a chance that the meteor will fall on them.

Trivia

 * When moving to another neighborhood, Sims must rediscover all the potions. However, because each discovery adds 10% to the discovery rate without resetting it, a Sim that had completed the Master Chemist challenge previously will not be able to complete the challenge ever, and when the Sim discovers 10 potions throughout the Sim's cumulative history, the challenge is marked as completed. However, the Sim does have another opportunity to discover each potion for free once.
 * When a Sim masters the logic skill, the game mentions Veronaville on the pop-up message saying, "Such brilliance and mental fortitude have not been witnessed since the Late Renaissance of Veronaville!"
 * If Showtime is installed, children and teenagers raising Logic often trigger the Master Magician Lifetime Wish, despite the career not requiring the skill.
 * To complete the Teacher Extraordinaire simply select "Friendly" then "Tutor" not "Tutor in..."

The Sims 4
In The Sims 4 is augmented by the genius trait, as it will occasionally give a focused moodlet, with focused being the ideal emotion for building logic skill. Gaining logic skill is required for the Nerd Brain aspiration and also for some careers.

Benefits
Similarly to the previous games, Sims with higher logic skill increase their chances of winning at games like chess. Logic skill is also tied to collecting, with benefits relating to this including the ability to collect and analyze plant, crystal and fossil samples at levels 2, 5 and 8 respectively. Also, Sims can unlock several Logic based interactions: 'Discuss Logic', 'Provide Logical Solution to Problems' and 'Rant Logically'.
