CPI Investigation Techniques & Equipment Usage 3 — Questions and Answers
Question 1: What is the correct procedure when an investigator believes they have personally experienced a paranormal event during a case?
- Immediately announce it loudly to the whole team
- Document it privately and disclose it only after the investigation to avoid influencing others (Correct answer)
- Leave the investigation site immediately
- Repeat the claimed experience multiple times to confirm it
Correct answer: Document it privately and disclose it only after the investigation to avoid influencing others
Personal experiences should be documented but disclosed after the investigation to prevent bias and suggestion from affecting other team members' perceptions.
Question 2: A thermal imaging camera detects temperature differences. Which natural cause can mimic a 'thermal anomaly' and must be ruled out?
- Magnetic field fluctuations
- Radiant heat from pipes, HVAC vents, or sunlight through windows (Correct answer)
- High-frequency sound waves
- Radio frequency interference from cell towers
Correct answer: Radiant heat from pipes, HVAC vents, or sunlight through windows
Thermal anomalies are commonly caused by radiant heat from infrastructure or sunlight, and these must be identified and excluded before attributing a reading to paranormal causes.
Question 3: In EVP classification systems, what does a Class A EVP designation indicate?
- The EVP was captured outdoors
- The EVP is clear and intelligible without the need for audio enhancement (Correct answer)
- The EVP required significant filtering to hear
- The EVP was captured with the most expensive recorder
Correct answer: The EVP is clear and intelligible without the need for audio enhancement
Class A EVPs are the highest quality, clearly audible and understandable without enhancement, making them the most evidentially compelling category.
Question 4: What is a 'control experiment' in paranormal investigation, and why is it important?
- An experiment performed only by the lead investigator to maintain quality
- A repeatable test under normal conditions used to establish a baseline for comparison (Correct answer)
- An experiment designed to control spirits during communication attempts
- A final review of all evidence before publishing findings
Correct answer: A repeatable test under normal conditions used to establish a baseline for comparison
Control experiments establish normal parameters so investigators can meaningfully compare them against potentially anomalous results observed during active investigation.
Question 5: Which type of microphone is generally preferred for EVP recording due to its ability to capture sound from all directions equally?
- Cardioid microphone
- Omnidirectional microphone (Correct answer)
- Shotgun microphone
- Lavalier microphone
Correct answer: Omnidirectional microphone
Omnidirectional microphones capture sound from 360 degrees, making them ideal for EVP work where the source direction of a potential voice is unknown.
Question 6: A 'Faraday cage' is sometimes used during paranormal investigations for what purpose?
- Protecting investigators from electrical hazards in old buildings
- Shielding equipment or a space from external electromagnetic interference (Correct answer)
- Containing claimed poltergeist activity in one room
- Amplifying weak EMF signals for easier detection
Correct answer: Shielding equipment or a space from external electromagnetic interference
A Faraday cage blocks external electromagnetic fields, allowing investigators to test whether EMF anomalies originate internally rather than from outside radio or electrical sources.
Question 7: What is the investigative significance of reviewing security or surveillance footage already installed at a reported haunted location?
- It replaces the need to conduct an on-site investigation
- It may capture pre-investigation activity without observer effect or contamination (Correct answer)
- It is inadmissible as evidence under CPI standards
- It only records audio, not video, making it less useful
Correct answer: It may capture pre-investigation activity without observer effect or contamination
Pre-existing surveillance footage captures the location without investigator presence, eliminating observer contamination and potentially documenting claimed phenomena under normal conditions.
