Hidden traits become available to Sims in specific careers, life states, or in some cases the children of a Sim with the hidden trait.
The Sims 3Edit
These traits are hidden but otherwise function similar to the standard traits. These hidden traits are often found in NPCs and Sims who reach certain career levels. Sims with these traits have a 50% chance to pass them onto their offspring.
|Burglar||Burglars must perfect their sneaking skills to properly liberate imprisoned items from the homes of neighbors. Burglars like to keep the skill in the family, so their children are able to sneak out like a pro at birth.||Found in burglar NPCs and Sims who reach level 7 of the Criminal career in Thief branch. Sims with this trait can "Sneak" instead of walking or running.|
|Can Apprehend Burglar||Police officers spend years learning how to best the most clever burglars. Luckily for their children, genetics helps [sic] them stop burglars without years of tedious training.||Found in police officer NPCs and Sims who reach level 3 of the Law Enforcement career. Sims with this trait can fight any burglars on home lot. It also slightly increases the chance of a Sim winning a fight, but only if the Sim with this hidden trait initiated the "Fight!" interaction.|
|Can Salute||Children of high-ranking military officials know enough about the military's rules and regulations to snap off a smart salute when they want.||Found in Sims who reach level 4 of the Military career. Sims who graduate from Fort Starch Military School also receive this trait. The salute learned from completing level 2 Scouting can only be used in childhood and does not activate this trait.|
|Immune to Fire||Fire Fighters are able to survive countless fires; not least because of their natural immunity to fire. It's a trait that they pass on to their children.||Found in firefighters, Sims working in the Firefighter profession, Bonehilda, and Genies. Sims with this trait cannot be killed by fire, but can still be singed. They also put out fires much faster than normal, and will autonomously put out fires - even if they lack the Daredevil or Brave traits[confirmation needed].|
|Makes No Messes||The descendants of maids have cleanliness imprinted on their genetic code so they never leave anything dirty.||Found in maids and resort maintenance workers. Sims with this trait never create mess, similar to an attribute of the Neat trait.|

|Pyromaniac||You can only get this trait in a Sim who is the offspring of a firefighter, or genie Sim. The trait allows them to set fire to objects of their choice, and they get positive moodlets for doing so!||Found only in the children of a firefighter or Genie. Pyromaniacs are able to transmogrify any fruit into flame fruit, start fires for a short time without destroying objects and can survive for up to three hours while on fire. When they are on fire their moodlet will be positive instead of negative.|

The Sims 4Edit
- This section is in need of additional information. You can help The Sims Wiki by expanding this section.
- If a Sim in a house has already bought the Fireproof Homestead lifetime reward, a Pyromaniac Sim will not be able to set a fire on that house.
- Despite the fact that Pyromaniac's fire does not harm anything, it will still trigger the fire alarms if there are any nearby, summoning the firefighter and leading to a fine.
- If a Sim has the Good trait and the secret Private Eye trait, the Sim won't have the option to beat up other Sims for information.
- The ability to Sneak with the secret Private Eye trait is only available for young adults and older.
- With the secret Can Apprehend Burglar trait, if the Sim has the Coward or Good trait, they are unwilling to fight burglars.
- Even though a Sim has the Immune to Fire hidden trait, they can still be caught on fire from inventing, making metal sculpture, taking an experimental treatment from the Science Career, or from a fire trap. They will get the Singed moodlet, but they won't die if they catch fire again.
- Sims can get the Unicorn trait by using a 3rd party mod.
- Using 3rd party mods or cheats to simply add the hidden traits for various occults does not properly apply occult status and will cause problems, unless the trait is "PlantSim".
- If using a mod and selecting the Rocker trait in Create A Sim, an animation will be played, unlike the other hidden traits. However, there is no description.
