Per 
It basically goes like this: in a town inhabited by [blanked out] people, there was once this guy named John [blanked out] who would act theatrically as a detective, solving “mysteries“ that only he knew of. People would describe him as a “roleplaying freak” that could not distinguish reality from his fictional world, but he was harmless most of the time and actually managed to get a job and maintain it. He himself presented no anomalous property: he was just kind of weird.
One day, however, during an intense bout of “detectivity activity”, as he called it, he forced his way in his neighbor’s house, during the night, and started ransacking it. He was searching for “the key to elucidate the bunnyfication of Bugs By Leon [Blanked out]!!”[1], as he kept shouting frantically.
Before calling the police, said neighbor tried chasing him away from his house and property, punching him in the face in the process, leaving a small blood stain on the hardwood floor of his living room. And that piece of wood with a blood stain would be SCP-xxxx-1
Foundation attempts to damage it in any way haven’t worked in the [blanked out] years[2] that SCP-xxxx-1 has been contained within Foundation territory. So it is contained in a normal cell, except measures should be taken for no human senses to detect it (it has a strong iron-like smell, emits a ticking sound and is not to be seen, touched or (presumably) tasted except in controlled experiments. If it happens to any human subject, even for a split second, they will become an instance of SCP-xxxx-2.
I plan for SCP-xxxx-2 instances to go in similar bouts of “detectivity activity “ as John [blanked out], though they won’t be able to wake from them until administered moderately powerful amnestics (I don’t know what class that would be yet). When several SCP-xxxx-2 instances gather together (as seen in a test log I would create, involving 5 D-class personnel), the effect amplifies to a point where termination is the only way of stopping it. Thus, this cognitohazardous effect would increase with other instances of SCP-xxxx-2 around.
I will need to elaborate on how SCP-xxxx-2 instances interact with one another, though. And the details of the “detectivity activity” must be worked on quite a bit. What I want to convey is the idea of absurdity: the “cases” such “detectives” are ‘’working on’’ won’t be really understood by foundation researchers, as most of the time, speech won’t be all that coherent. A strong liking for things that are ‘’ elementary my dear Watson ‘’ and magnifying glasses will be expressed, however. Also, all instances will call themselves ‘’truthsters’’ and will seek to ‘’ terminate any and all mysteries’’[3]. Such instances won’t be inherently aggressive, unless impeded in their ‘’work’’, though they will be intrusive.

[2] Probably several years.
[3] Both the test log (involving 5 instances of SCP-xxxx-2 together) and an interview log with one instance alone will respectively underline behavior in groups and behavior alone. Groups of them won’t respond to inquiries from unaffected individuals, though they will respond when alone.
