Memetic Inoculation Required

By continuing to read this document, you are voluntarily consenting to treatment with a Class II memetic agent that will allow you to normally perceive the essence of the anti-memetic nature described herein. The action of the memetic agent is long term. Employees assigned to work with SCP-4004 are required to undergo the treatment.

To undergo the treatment, look carefully at the file attached to this article. Subjects who have been successfully processed will be able to perceive the phenomenon exactly as it is described.

Special Containment Procedures: Due to the anti-memetic nature of the anomaly, little containment measures are required on the behalf of the Foundation. Foundation Web-Crawler AI "Gaslight" is to monitor social media for any presense of SCP-4004-2, launching disinformation campaigns against these individuals.

MTF Epsilon-7 "The Forget-Me-Nots" is to impede the development and distribution of mnestics among the civilian population.

Undercover Foundation agents are to be inserted into all governmental positions in the city of Canterlot, USA as soon as possible.

Description: SCP-4004 is an anti-memetic phenomenon, currently affecting 9█.█% of the global population. Any information regarding anomalous happenings in the city of Canterlot, USA is dismissed as false, and is soon forgotten by the subject (SCP-4004-1 from hereon). The time of information retention differs from individual to individual, and positively correlates with one's Cognitive Resistance Value (CRV). The use of Class X, as well as Class Y mnestics has proven to be effective in negating the anti-memetic effect.

-SCP-4004-1 percieves the happenings to be out of the norm;
-SCP-4004-1 percieves the information to be truthful;
-Canterlot is either explicitly stated, or implied to be where an anomaly has occured;

SCP-4004-2 is the remaining 0.█% of the global population, which remains immune to SCP-4004 effect. Instances of SCP-4004-2 differ in race, sex, upbringing and beliefs, save for one defining characteristic. Each SCP-4004-2 instance can be traced to have been originated from Canterlot.

Due to the number of SCP-4004-2 instances, and their widespread presense no restrictive actions are to be taken regarding them. Each SCP-4004-2 instance currently employed by the Foundation are to be analyzed for any other markers that allow them to be singled-out among the crowd.

D-88123 is shown footage of demonic possesion taking place at Canterlot High School. The location is diliberately pointed out.

Result: D-88123 dismissed the footage as a 'promotional campaign' for an unspecified movie, noting the low-quality of visual effects. Approximately three minutes after seeing the footage, D-88123 was once again asked what he thought of it, but claimed to have no memory of it. When events taking place in the footage were described to him, D-88123 stated that he had never seen it. When asked what he was doing for the past ten minutes, D-88123 appeared nervous and confused, unable to answer the question.

D-88123 is shown footage of demonic possesion taking place at Canterlot High School, however all landmarks that point to the specific place of the accident is redacted.

Result: The subject reacted in an agitated manner, asking multiple times wether or note the footage was real or not. A positive reply did not trigger SCP-4004's effect. Half an hour later, D-88123 was able to recall the footage shown to him with no issues.

"It seems like SCP-4004 triggers only when the anomalous event is diliberately stated to be from Canterlot, simply seeing the footage from CHS does not trigger it. Let's try it again, without obscuring landmarks." - Dr. Theory.

D-88123 is shown footage of demonic possesion taking place at Canterlot High School. The subject was not informed on the location of the accident.

Result: The subject reacted in an agitated manner up until he noticed CHS's name sign, calming down significantly from thereon. When asked wether or not the footage was authentic, D-88123 denied the notion. Approximately three minutes after seeing the footage, D-88123 was once again asked what he thought of it, but claimed to have no memory of it. When events taking place in the footage were described to him, D-88123 stated that he had never seen it. When asked what he was doing for the past ten minutes, D-88123 appeared nervous and confused, unable to answer the question.

"Good to know information gained by deduction also triggers SCP-4004's effect. Prepare the subject for tomorrow's testing." - Dr. Theory.

"I'm overruling Dr. Theory's orders. D-Class are far cheaper than amnestics, and they're a dime a dozen, use more than one." - Director Memory.

Dr. Theory strikes a conversation with the subject, casually mentioning a made-up extranormal event that happened in Canterlot in an attempt at humor.

Result: D-31347 brushed the comment off, commenting it was "the worst joke [she] ever heard". Thirty minutes later the subject was able to recall the conversation in full.

"It seems the subject has to take the information seriously for SCP-4004's effect to trigger." - Dr. Theory.

Note: D-11883, earlier exposed to the effects of SCP-████, is convinced that the movement of trees causes wind and the fact is completely normal. Any attempt to rectify this to date has been ineffective.

Both subjects are given a fabricated document containing 'proof' that wind is caused by movement of trees in the Canterlot area.

Result: D-11883 read the document with a disinterested expression, asking researchers "why [they] provided [her] with elementary school level material". Thirty minutes later the subject was able to recollect the experiment fully.
D-31347 expressed initial shock, but calmed down considerably when SCP-4004's anomalous effect triggered. Curiously, the two subjects would begin a heated debate on the credibility and authenticity of the document. The experiment was stopped when D-31347 assaulted D-11883 when the latter refused to "drop this stupid joke".

"The subject needs to consider the information anomalous for SCP-4004 to take effect. Curious." - Dr. Theory.
