Trait is a personality system in The Sims 4, similar to the trait system in The Sims 3. The personality system as a building block of Sims in The Sims 4 is a combination of trait from The Sims 3 and aspiration from The Sims 2. There are three kinds of traits in the game: normal traits, bonus traits, and reward traits. Each kind has different ways to earn them.
As Sims socialize with others, they may reveal their traits from certain interactions. For example, asking a Sim's career will reveal if they have the Ambitious trait, or flirting with a Sim may reveal the Romantic trait. The Observant reward trait allows a Sim to instantly learn the traits of other Sims.
List of TraitsEdit
Adult sims created in Create a Sim may have up to three traits, and a bonus trait relating to their chosen aspiration. All traits affect a Sim's behavior and emotions, for example, a Creative sim may randomly become Inspired, while a Sim that Loves Outdoors will sink into a low mood if they stay inside too long.
Unlike The Sims 3, there is no soft limit on the amount of traits an individual Sim can have. Further traits can be earned by either completing aspirations and receiving reward traits, purchasing traits with Satisfaction Points, achieving a high level in the Doctor career, and even dying.

Sims will receive a unique reward trait when fulfilling aspirations. There is no limit on the number of aspirations that can be completed, and thus no limit on the number of aspiration reward traits that can be earned.
Child Aspiration Reward TraitsEdit
These traits can only be earned when the Sim is a child and completes a child aspiration.
Satisfaction Reward TraitsEdit
Certain traits can be purchased with Satisfaction Points. Unlike regular traits, these traits are of narrow focus and usually only grant a single ability.
Career Reward TraitsEdit
|Sickness Resistance||Sim must be level 8 in the Doctor career.||Resilient Immunity, Sims will have a lower chance of getting sick and will recover from sickness faster.|
The Sims 4 features numerous hidden traits that are never visible. Many of them are used only for technical purposes, such as marking which secret lots have been visited, or to provide functionality for NPCs. Some hidden traits function similarly to regular traits, but are simply not visible.
|Alien||Alien Sims will have this trait. It can only be viewed when setting Club membership requirements. There is no in-game description.|
Other hidden traits like Left-handed and Right-handed can be set in debug mode or by using cheat codes.
