Perception Filter	comment	Your standard Invisibility typically makes you transparent to light. While quite effective, it does have a number of catches, such as retaining the ability to be heard or otherwise detected, possibly forcing you to be an empty-handed Invisible Streaker, or even rendering you blind if it works realistically.note Your eye works by absorbing light energy and converting it into electric impulses in your nerves. Thus, if your eye itself, with the retina and all, were to be transparent, it would be the same as having retinal loss â€” meaning no light absorption, causing no electric signals being generated and making you blind. In short, it won't make you stealthy overnight. The perception filter does away with these catches. This ability affects the minds of the observers, making them subconsciously look in another direction or pay no attention to the subject, or erasing the subject from short-term memory. It does have a few catches of its own, though: it obviously won't work on cameras and other objects that don't have a mind to screw with â€” although it's possible for the images they create to still prevent people from seeing them properly. It also tends to fail if the user draws too much attention to themselves, so the Highly-Visible Ninja and Screaming Warrior will find it useless. Very often used by witches in fantasy, aliens in Science Fiction, and anyone else trying to pass unnoticed among muggles. The Trope Namer is Doctor Who, more specifically a piece of circuitry of the same name, which allows the Doctor's TARDIS to blend into its surroundings, no matter what form it takes on landing. Even in its iconic anachronistic police box form, it's been stated that it can shift the perception of the person looking at the TARDIS to make them not notice it unless they actively try to. See also: Weirdness Censor, where it's the Muggles themselves that choose to ignore it, Invisible to Normals, where it's the laws of nature that cause it, and The Nondescript, where it's something/someone so unremarkable that no one gives them a second thought. Compare Jedi Mind Trick.

Perception Filter / int_136469af	comment	In Pact and its spinoff Pale, magical practitioners have the ability to see connections between people and objects that denote the relationships between them. The simplest and most straightforward form of magic is applying power to cut a connection, which has this effect-people fail to notice the person or object they were tied too, or forget what they were talking about. Advanced manipulation of connections falls under the schools of enchantment and illusion, the use of which is suggested to be a major contributor to the existence of the Masquerade which has people unaware of when magical disaster strikes-the location will exist on a map, but nobody will ever go there.

When Imp's power is active, anyone nearby immediately forgets her presence and involvement in events, even if they were physically touching her. The villain Nice Guy has a lesser version where he makes people perceive him as a friendly harmless bystander, someone to be politely dismissed and then summarily ignored. However, it only works on people he's aware of; Revel identifies him from surveillance, and the aforementioned Imp quickly recognizes him as an enemy once she activates her own power. In addition, it does nothing to protect him from people who are willing to kill harmless bystanders, whether out of cruelty or because the situation meant that all bystanders were in a bad enough situation to deserve a Mercy Kill.

Against humans and faunus though, it doesn't work. Emerald Sustrai's semblance can make anyone hallucinate by altering the sensory information the target's brain processes. While she's fine using it against individual targets, making multiple targets hallucinate seems to drain her much faster, with two people causing a headache, and an entire group of about ten causing her to faint from mental exhaustion.

Perception Filter / int_3b08dfc9	comment	In Pillars of Eternity, the Grieving Mother uses her Cipher abilities to make others see her as a random peasant beneath notice. However, the Watcher is able to break her filter through their soul-seeing powers. Not even the other companions notice her; asking Hiravias about her will cause him to wonder why some random woman is following you around. Her filter also sets off some of the most hilarious moments in the game. Most prominently and (darkly) is an event in Skaen, the God of Evil's Temple, where if the Player Character's Cruel reputation is high enough, the pool of blood will offer you to sacrifice one of your companion for a permanent status bonus. Normally, accepting the pool's offer will cause the other companions to react in horror to the sudden death of one of their comrades (but they won't know that the Watcher is responsible). If Grieving Mother is chosen as the sacrifice, however... No one cares. They don't even know she is there because of her glamour. Doing so will earn you some rather funny reactions from the others, including Durance scratching his buttock with his staff and EdÃ©r saying out loud that he is going to eat roasted chicken at the inn, while Grieving Mother is choking in her own blood.

Perception Filter / int_41b0198a	comment	The Dresden Files: In Fool Moon, protagonist Harry Dresden attempts to create a potion of invisibility. It's quite possible for him to become truly invisible with such a potion, but it won't hide him from the other senses of the giant super werewolf he thinks he's going to run into. Instead, he cheats by using the effects of this trope. The potion causes those around him to avoid paying any real attention to him and act as though he were so mundane as to be not noticeable—in this case, a janitor. This actually turns out to be a problem when he wants to get an Innocent Bystander's attention to warn them about the rampaging werewolf, but the potion's effects make it so that the bystander hears his yelling as meaningless small talk. One of Gard's valkyrie-magic runes is "Routine". While not good enough to hide something unusual from sight, when Harry casts an illusion to make himself, Gard, and Mouse look like malks in the short story "Heorot", the rune causes a pack of real malks to see the three as "just a normal part of their day."

The Foundation has a class of drugs called "mnestics" which provides protection against some Perception Filters. SCP-268, a hat that gives its wearer one of these. Wear it long enough, and it's permanent. SCP-055 is a "self-keeping secret". No one knows (or more accurately, no one remembers) how it came into Foundation possession, who devised its containment procedures and why, what it is, or even that it exists. This effect even goes so far as to apply to documentation on the SCP; many reports, photos, and videos of it exist, but as soon as you stop looking at any of them you will forget all about them. Because of this, it's The Dreaded; nobody knows what else it does, and it could be horrendously dangerous without anyone knowing. It's implied that it most likely is horrendously dangerous. SCP-451 is a former Foundation agent who is unable to perceive other humans, their actions, or any effort to communicate with him, leading him to believe that he's the last human on Earth. SCP-2256 is a species of Gentle Giant Sauropod creatures who use an anti-memetic ability to appear invisible. Not only that, any information of them gradually corrodes away, with photos turning blank and writing being censored. It turns out that this is necessary for their survival as being observed was harmful to them. When a direct photo of one was taken after a device was used to remove this filtering ability, it instantly died. SCP-1504, aka "Joe Schmo". No matter what he does, it will be perceived as perfectly normal. During an interview he punched the interviewer in the face, but said interviewer just took a moment to clean up the nosebleed and didn't know how he got it. He only has two other abilities: he's completely indestructible, and cause electrical systems to fail just by being near them. The Foundation only found out about the Perception Filter after he caused a massive containment breach and subsequent destruction of the site he was held out, and they still haven't found him yet. SCP-3933 is the song "Toxic Soul" by the 80s Hair Metal band Tyrannosaurus Flex. Once, they were the most famous band in the world, possibly even in history, but today, nobody has ever even heard of them. Why? Because anyone who hears that particular song by them not only forgets they ever existed, but can no longer percieve them at all. For example, if an affected person were to watch one of the band members pick up and carry an object from Point A to Point B, to them that object would appear to be teleporting. Since the band was so famous, pretty much the only people who haven't heard the song are Foundation personnel who deliberately didn't listen to it to avoid becoming affected.

Perception Filter / int_468bebb0	comment	Discworld: Trained witches and Susan Sto Helit can "fade into the foreground". This seems to be a theme in Discworld: Pratchett maintains that if something is utterly outlandish and impossible enough (for example, a donkey standing on top of a very very high pole), humans will go out of their way to not notice it or subconsciously pretend it doesn't exist. Animals, who do not have the advanced mental perception filters humans have that enable them to see exactly what isn't there and not see what is, do not fall under the blanket of this trope. Death himself uses it to go unnoticed, though it may be a case of outright Weirdness Censor. An interesting effect in Mort is that crowds which unconsciously part to let Death through close right up again on his apprentice; they do know Mort is there, they just don't care. Even though been explained like it's based on a Weirdness Censor, this is still a special ability or property that can be turned on or off, or had or not had by the same being in the same kind of circumstances. So, for example, Susan can choose to become invisible this way, and Death can choose to be visible in his true form even to Muggles. In Thief of Time, there's a scene where a clear distinction is made between Perception Filter and Weirdness Censor: Susan doesn't have to turn on her invisibility, as it were, because, as a Gothically dressed young lady walking a horse inside where she is, she really is too incredible for anyone to register. In Mort, Princess Keli effectively becomes invisible to everyone by accident because according to fate, she's supposed to be dead. People's brains keep telling them she's not there, she can only get them to notice her with difficulty, and they tend to forget her right away. Defied: she hires a wizard who can see her to remind people of her, and they post posters with her face and have her name shouted everywhere.

The one most frequently seen, used by the Child-Goddess Aphrael (also known as 'The Nimble Goddess' or 'That damn sneaky thief that you just can't hate even though she just robbed you blind 'cuz her smile is so cute'), is basically this - she magically diverts people's attention, so they sorta' know you're there, but they don't pay attention to you. They'll even step out of the way to let you past, without noticing that they're doing it.

This also means it can be used to calm down allies (useful when escorting a psychotic and drugged Jayne) but it won't work on machines (like security cameras and metal detectors) and attempting to use it when a hostile NPC can see you causes their anger to burn out your power. From a programming point of view, it also allows the developers to leave the NPCs' reaction animations unchanged (enemies just act like friendly NPCs when you walk past them).

At first, they sit slumped against walls, completely ignoring your character as you pass. They give no souls when killed, so killing them is a waste of time. Eventually you stop noticing them entirely.

That is why no Other has to worry about their car being stolen. If humans simply thought the car wasn't there, they try to park in that spot. This way, they don't perceive the car but also keep on driving. When Anton has to avoid using his powers in order to appear human, he suddenly has to be worried about leaving his car in a "bad neighborhood".

Perception Filter / int_6ac55ec7	comment	Dungeons & Dragons: AD&D: Apart from psionic invisibility, which is, obviously, a Jedi Mind Trick, regular invisibility is an illusion spell, so it affects the visual perception of the observers so they won't see the invisible target. That's why most invisibility spells are immediately ended if the subject attack anybody since that is much harder to ignore. In the game's third edition (and its offshoot Pathfinder), this is spelled out even more clearly — some forms of invisibility are glamers (mind-affecting tricks), while others are images (visual illusions). It's important because of the wide range of enemies, some of whom (zombies and giant ants, for example) have no mind to affect. Undead are among the creatures immune to standard mind-affecting magic, but in turn spells specialized against them for this purpose do exist — especially hide from undead which affects absolutely all of their mystical senses. Some other spells (such as shroud of undeath or undead mask) don't make one invisible to undead, but instead make the subjects appear as other undead rather than living beings, which generally mean they will be ignored. In both cases, actually attacking an undead will usually end the effect, as with regular invisibility.

That said, most charms aren't perfect, and other mythical are occasionally able to see defects in other mythicals' charms, though most humans aren't able to notice. The hotel automatically translates everyone's words into languages other people can understand.

It's quite possible for him to become truly invisible with such a potion, but it won't hide him from the other senses of the giant super werewolf he thinks he's going to run into.

He has a psychic power that allows him to force others not to notice him. His unconscious use of this power when he's nervous makes his social life awkward, but it is quite useful for other things. The limitations are that he has to be looking someone in the eyes for it to work, but when it happens, they will literally forget he was even there. It eventually became listed among the "officially recognized" psychic powers in the setting and was named "Plateau Eyes", based on the fact that the original novel was set on the colony world Plateau.

Perception Filter / int_ac8b90f5	comment	In Mage: The Ascension, Mages can buy this ability as the background "Arcane", which means people tend to forget them right away after seeing them. Entertainingly, Arcane impacts basic object permanence at high levels, also impacts paperwork, and cannot be turned off. This tends to result in a fair degree of sociopathy in high-Arcane players: why rent that car when the official records showing you paid will disappear in minutes and the clerk is going to forget he rented it and call it in stolen anyway? Just steal a car in the first place. If you're high enough Arcane that the records disappear in minutes, it's actually still better to pay, because if they associate the memory with you then the entire car rental company will lose all record of having that car in the first place. The Gone Horribly Right level is usually one or two dots, where people can still see and remember you and things associated with or near you, but your existence fuzzes out after a few weeks. Expect your landlord to continually be accidentally re-renting your apartment and your credit cards to be declined. The Mind sphere can create an obfuscate-like effect, but the details differ to any such use, due to the flexibility of the spheres and foci. A technomancer could make it so it affects cameras as well, or any sort of mechanically-minded being, or it could work only on those things specifically. It is, however, advertised as much more reliable than normal invisibility, especially as it can even lightly influence people to get out of your way, without noticing you. Mage: The Awakening, the game's spiritual successor/sequel, has a less powerful version of the same skill, which can be suppressed.

Perception Filter / int_bd1137ca	comment	Illuminatus! gives us an interesting example in the form of the nonsense word "fnord", which is this trope to itself due to society as a whole being conditioned from an early age to immediately forget it after they've read it. However, forgetting it provokes an uneasy feeling in the reader, causing them to attribute this apparently sourceless discomfort to the actual content of whatever message the word was written in. The Illuminati strategically pepper certain documents with the word in order to force a negative reaction and dissuade people from investigating any further into what they've read. "Seeing the fnords", breaking one's mental conditioning and gaining the ability to consciously notice the word, is portrayed as something akin to the conspiracy theory version of enlightenment. This being the sort of novel that it is, "seeing the fnords" is mentioned more than a few times long before it's actually explained what fnords are.

Other examples include the pavement-stone-lift used by Torchwood's Cardiff branch (it was permanently imbued with the TARDIS's field during the rift storm in "Boom Town"). "Aliens of London"/"World War Three" implies that this is in effect to explain why the zippers on the Slitheen's Human Disguises, which are on their foreheads, are only seen when the Slitheen wearing the disguise is actively unzipping it, even when their forehead is bare. It's possible to beat the perception filter with sufficient training. The Master reveals that he can detect people who are using filters. Suzie in the Torchwood episode "Everything Changes" reveals that she has trained herself to resist the "invisible lift's" perception filter. Some human organisations like Torchwood One and the Church condition their personnel against perception filters as part of their mental intrusion defense training. In "The Sound of Drums", the Doctor extends the effect to the TARDIS keys he and his companions carry, allowing them to avoid detection after the Master has them declared public enemies. "The Time of Angels": The Doctor namedrops it as the probable reason why neither he, River, or anyone else noticed that the "statues" in a maze built by an extinct two-headed species only have one head each and are actually decayed, wingless Weeping Angels. "Low-level perception filter. Or maybe we're thick." In "The Vampires of Venice", the titular vampires only look human due to a complicated perception filter that combines with an actual emitter that changes their appearance to disguise their true form (though basic survival instincts prevent it hiding their teeth). The emitter scans the subject's mind to find out what they expect to perceive and then change the wearer to look like that. This is used to explain why they don't show up in mirrors â€” the subject's brain doesn't actually know what to fill the space with. "The Lodger": The rogue time machine posing as the upstairs flat of Craig's building is using one powerful enough that not only can it masquerade as the upstairs flat, it can make people think that that one-storey building has always had an upstairs. Used to terrifying effect with the Silence, whom you forget you encountered as soon as you are no longer looking at them. They were originally created as religious confessors, so people could confess their sins and then forget having done that, only feeling unburdened. "Face the Raven": Trap streets have "misdirection circuits", which render them so unnoticeable that whole communities of alien refugees can hide out in the middle of London. To find one, the Doctor flies Clara over London in the TARDIS and focuses on the bits her eyes skip over. "Rosa": The antagonist hides the suitcase containing his gear in an empty warehouse this way. The Doctor finds it by tracking the artron energy it gives off due to having traveled through time. "Spyfall": The latest incarnation of the Master, who happens to look Indian, uses one of these to make himself look white while disguised as a Nazi officer in 1943 Paris. The Doctor leaves him in a situation in part by deactivating said filter, forcing him to take The Slow Path back to the 21st century. "The Haunting of Villa Diodati": When the villa abruptly turns into a Mobile Maze with hallways twisting around each other to keep several groups of characters trapped in the rooms they're in, it turns out that a perception filter is involved in the process. Dr. Polidori's sleepwalking makes him immune to the filter since he's not perceiving his surroundings anyway, allowing the Doctor to figure out what's going on.

Having achieved Lyctorhood through Gideon's sacrifice, Harrow is aware that the full process of becoming a Lyctor may consume what's left of Gideon's soul. Which is why she has undergone radical brain surgery, enhanced by necromancy, to erase Gideon from her memory and rewrite the events of Canaan House so that Ortus, the previously deceased cavalier of the Ninth House, was there instead. This has the side effect of her hearing "Ortus" whenever anyone says "Gideon," which makes the presence of one of her fellow Lyctors get very interesting...

Perception Filter / int_d1bf110e	comment	Sleepy Princess in the Demon Castle: Zastral, the Tenth of the Ten Elders, didn't show up until over 300 chapters into the series because of an incident with one of these. Originally tasked with infiltrating the hero's party, he had intended to cast a spell to make himself unrecognizable to demons so that they wouldn't recognize him and blow his cover. Unfortunately for him, he sneezed while casting the spell and accidentally erased himself from their memories completely and rendered them incapable of perceiving him. He eventually figures out that he can break the spell by drawing enough attention to himself to overcome its effects (as all it does is cause the demons to mentally filter him out), but all of his attempts to do so by creating a ruckus in the demon castle are either inadvertantly foiled by Princess Syalis or blamed on her. He eventually succeeds via a combination of casting a Gender Bender spell over the whole castle, and Syalis herself being able to perceive him more easily because she's not a demon (and had also gained a degree of extra-sensory perception due to some unrelated shenanigans of hers).

The wizard uses spells like "Look Over There", "Ignore Me" and "This Isn't A Door" when trying to sneak around. Likewise in the Ladies of Mandragyn, an untrained wizard stops soldiers from looking his way but is caught when the gate guards use a mirror to search for him.
