Trait (The Sims 4)

sims

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 traits from The Sims 3 and aspirations from The Sims 2. There are four kinds of traits in the base game: personality, bonus, death and reward. Each kind has different ways to earn them.

Learning traits
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.

Personality traits
Adult Sims created in Create a Sim may have up to three traits. Teens created may have up to 2 traits, children may only have 1 trait, and toddlers have 1 personality trait that is different from the other traits. 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.

The following lists all traits that appear in the game.

Toddler traits
Toddlers can only have one of the following traits. Regular traits can be selected once the toddler Sim ages up to a child.

Bonus traits
Each Sim receives a bonus trait upon choosing their initial aspiration that will aid them in fulfilling its goals. Bonus traits are retained even if the Sim's aspiration is later changed.

Ghost traits
Sims will receive a unique trait upon death that describes the manner of their passing and the abilities they have as a ghost. These traits can only be seen within the simology panel.

Aspiration reward traits
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.

It is not possible for aliens to learn the Slinger of Spells, I am the Master, A True Master, Master Mixer, and Regained Humanity traits without the use of cheats, as they require vampire or spellcaster occult status, and aliens cannot change into those types.

Inherited traits
Inherited traits are traits that are passed down through generations and can only be achieved from having one or more parent possessing them at the time of birth.

Toddler skill reward traits
These traits can only be earned by toddlers after increasing their skills.

Child aspiration reward traits
These traits can only be earned when the Sim is a child and completes a child aspiration.

Character value traits
With The Sims 4: Parenthood, Sims with extremely positive or negative character values will earn the appropriate trait once they become young adults that correspond to the extremity of their character values.

Satisfaction reward traits
Certain traits can be purchased with Satisfaction Points. Unlike regular traits, these traits are of narrow focus and usually only grant a single ability.

Temporary traits
These traits are bestowed upon a Sim for a short time only before being removed.

Sage traits
Following reward traits are used by The Magic Realm's sages only and have no official name.

Childhood phases
Childhood phases in the The Sims 4: Parenthood are temporary traits randomly experienced only by child and teen Sims.
