Per 
After pacifying a location recently host to SCP activity (“Pacifying” in this case being determined to entail returning the location to a normalcy State of -2 or above on the Ritterbusch Scale), an essential part of debriefing possible witnesses and increasing normalcy is the Baseline Questioning Procedure, henceforth to be referred to as BQP.
Purpose
The BQP, a series of 15-20 questions designed to determine the intensity of a witnesses reaction to an abnormal event, their state of mind, and whether or not induced amnesia is required.
Risks
The main risk associated with BQP is that it is mainly deployed after a level of normalcy has already been established, and the wording of certain questions can counterintuitively lower the state of normalcy, causing alarm and suspicion in the interviewee. Another risk associated with BQP is that it relies on accurate answers from the interviewee, or an accurate perception by the interviewer.
Procedure
The BQP is only to be conducted in a setting of relative privacy and safety. Questions are to be asked to one individual at a time. Notes should be taken on a sheet of paper, clipboard, or notebook, even if these notes are ultimately not used for anything by the interviewer. If at any point the interviewee begins to show suspicion or alarm about the nature of the questions, the interviewer should immediately shift to more mundane law enforcement style questions. If multiple agents are available, two should be involved in every BQP, one interviewer and one observer. It is not advisable to perform the BQP.
Scoring
Each of the 15 questions is scored out of four points, 0 indicating a normal answer, 4 indicating an alarming answer. In addition to this, the interview is scored out of ten points based on interviewee behavior. These points are totaled and the final score is out of 70 points. A score of 25 or below is considered normal. A score of 26-40 is considered above average, and deserving of induced amnesia or similar measures just to be safe. A score of 41 or above requires instant relocation and containment in a secure facility until the problem can be identified and resolved.
The Questions
1) Name and Date of Birth?
(Any difficulty in answering this question should be considered a cause for alarm. This question should always be asked first in order to increase the appearance of normality)
2) Do you believe events in the future can retroactively have an effect on events in the past?
(A "No" or similar statement is considered a normal answer)
3) If you flip a coin three times and get heads each time, do you believe that if you flip the coin again you have a higher chance of getting tails?
(This question may require repetition in order to be comprehended. Any answer other than "No" must be rated at least a 1, however the answer shouldn't be considered alarming, and thus rated higher than a 1, if the interviewer judges this to be due to the interviewees simple lack of understanding or probability.)
4) If a tree falls in the middle of an empty forest and no one is around to hear it, do you believe it still makes a sound?
(A "Yes" or similar statement is considered a normal answer)
5) Do you often feel as if people act differently when you are around?
(A qualified "No" or similar statement is considered a normal answer. Obviously an interviewee is expected to understand that humans act differently depending on the situation, but alarm should be registered if the interviewer notices signs of exceptional paranoia)
6) Do you believe you can sense whether or not you are being watched?
(Expressing a feeling of sensation occasionally is considered a normal answer, as long as the interviewee acknowledges they rationally know this to be impossible.)
7)
a. If you could go back in time and kill baby Hitler, would you?
b. Why?
("Yes" and "No" are both considered normal answers. Abnormal responses can include answers such as "Who is Hitler?" "Would it work this time?" or "I would kill baby Hitler in the present.")
8) How many days last week would you estimate you purchased beef products (steak, burgers, etc)?
(The interviewer is expected to be able to recognize a suspicious or abnormal response on their own)
9)
a. Have you noticed an unusual amount of household objects go missing recently?
(If the answer is no, proceed to Question #10, if the answer is yes, proceed with question 9 b)
b. Does this alarm you?
(Note: minor annoyance is considered a normal answer. Any answer is considered normal if they attribute the disappearance to a logical explanation, i.e. thieves, careless misplacement, pets)
10) Are you a lucid dreamer?
(A "No" or similar statement is considered a normal answer. A "Yes" can also be considered a normal answer if the interviewee sometimes experiences partial lucidity in which they are aware they are dreaming and yet continue to "play by the rules" of the dream)
11) Does your family have any history with Schizophrenia?
(An answer consistent with observations about he interviewee is considered normal. If the Interviewee answers that they themselves suffer, their score can be automatically reduced by 10 points)
12) Do you often have trouble distinguishing between reality and fantasy?
(A "No" or similar statement is considered a normal answer)
13) Do you believe extraordinary claims require extraordinary proof?
(A "Yes" or similar statement is considered a normal answer)
14) Do you believe we live in a universe governed by fundamental laws which cannot be changed?
(A "Yes" or similar statement is considered a normal answer. It is also considered normal for an interviewee to show suspicion at the nature of this question)
15) Do you want to go home?
(This question can be changed to "do you wish for me to leave?" or "do you want to go back to your normal life now?" depending on the circumstances. Any expression of desire to return to a state of greater normalcy is considered a normal answer)
