Trait conflict describes a situation where a character (e.g. a Sim, pet, Plumbot, Servo) cannot have a particular trait, because they already have another trait that conflicts with it. Traits that conflict are often considered "opposites" of each other, such as the evil trait conflicting with the good trait.

Trait conflict can also be used to describe a situation where two characters have traits that oppose one another. If one character exhibits actions or behaviors based on a conflicted trait, a character with an opposing trait may react negatively to it, harming the relationship between the two characters.

The Sims 3[]

If an incompatible trait is learned, relationship will be decreased slightly. Using a social whose trait prevents the social from working, for example a joke about work on a workaholic or "Talk about Computers" on a technophobe, will learn the trait and may decrease the relationship if that trait has a conflict. The "Observant" lifetime reward can cause conflicting traits to be learned when the Sim starts to socialize with that Sim. Vampires' ability to read minds may cause them to learn conflicting traits faster.

If a Sim has more than one trait that results in a conflict and they share traits as well, both positive and negative interactions will occur.

Relationship is no longer decreased when an incompatible trait is learned. On the other hand, learning the shared trait will no longer increase relationship either. Social effectiveness from traits are same as The Sims 3.

The Sims 4[]

Examples of traits that conflict with Cheerful, Childish, and Hates Children

Trait conflict returns in The Sims 4. Like The Sims Medieval, there are no relationship changes from learning about a trait conflict or compatibility. However, Sims with conflicting traits will have a harder time getting along. Freegan from The Sims 4: Eco Lifestyle and lazy from the base game are currently the traits with the most conflicts in the series, with five conflicting traits each.
