Likes and dislikes

Likes and dislikes are a system that determines aesthetics and activities Sims prefer in The Sims 4, which were added in patch 113 of the base game. It is similar to the favorites system in The Sims 3. They can either be chosen in Create a Sim or be developed through gameplay, and Sims can have up to twenty in total. There are three categories of likes and dislikes present in the base game (activities, colors, and music genres), with a fourth category added in The Sims 4: Dream Home Decorator (décor).

If a Sim is doing an activity in a particularly good or bad mood, the player will occasionally be prompted to add it to their likes or dislikes. The longer a Sim does an activity they dislike, the tenser they get, and they will never do a disliked activity autonomously. Sims can also enthuse or complain about their preferences to other Sims, and their reaction depends on their own preferences. Likes and dislikes are used extensively in the interior decorator career, where decorators have to figure out their clients' preferences first before completing a renovation for them.

Likes and dislikes can be changed at any time by accessing Create a Sim through a Sim's "Simology" tab in live mode (or through any of the other ways of accessing CAS).
