Decline to share any client-identifying information without explicit written consent from the client (Correct answer)
Provide anonymized findings only if the journalist agrees not to publish names
Refer the journalist to the client directly
Share general findings since the investigation is complete

Correct answer: Decline to share any client-identifying information without explicit written consent from the client

Client confidentiality requires obtaining explicit written consent before sharing any case information with third parties, including media.

Question 10: An investigator reviews a night's data log and notices CO2 levels rose steadily from 400 ppm to 1,100 ppm over four hours. What is the most probable cause?

Accumulation of exhaled CO2 from investigators in a poorly ventilated space (Correct answer)
A CO2 sensor calibration error unique to night hours
Paranormal entity breathing
Paranormal investigations always produce CO2 increases

Correct answer: Accumulation of exhaled CO2 from investigators in a poorly ventilated space

Human respiration releases CO2, and in sealed or low-ventilation environments levels naturally accumulate over time as the investigation proceeds.

Question 11: When reviewing IR (infrared) video footage, which artifact is most commonly mistaken for a paranormal anomaly?

Audio bleed-through causing visual distortion
Frame rate mismatch creating ghosting
Dust particles reflecting IR light (orbs) (Correct answer)
Camera lens flare from visible light

Correct answer: Dust particles reflecting IR light (orbs)

Dust particles in close proximity to the IR illuminators reflect light and appear as bright floating orbs, the most common camera artifact misidentified as paranormal.

Question 12: What is the primary purpose of a baseline EMF reading taken before an investigation begins?

To calibrate the investigator's personal sensitivity
To detect the presence of spirits before the team enters
To ensure the building's electrical system is safe
To establish normal electromagnetic levels so anomalies can be identified by comparison (Correct answer)

Correct answer: To establish normal electromagnetic levels so anomalies can be identified by comparison

Baseline EMF readings document the location's normal electromagnetic environment, making genuine spikes detectable as deviations.

Question 13: Which of the following best describes the Instantaneous Field of View (IFOV) of a thermal camera?

The maximum frame rate the sensor can capture
The angular size of a single detector pixel, determining the smallest object that can be resolved at a given distance (Correct answer)
The lens focal length measured in millimeters
The total battery capacity in milliamp-hours

Correct answer: The angular size of a single detector pixel, determining the smallest object that can be resolved at a given distance

IFOV determines how small a target can be and still be distinguished as a separate object at a given distance; a narrower IFOV means finer detail and better anomaly isolation.

Question 14: During an outdoor night investigation, a team member becomes disoriented and cannot locate the group. What should they do first?

Continue moving toward where they last saw the team
Stay in place, activate a whistle or flashlight signal, and call out (Correct answer)
Use their EMF meter to detect team members' electronics

Correct answer: Stay in place, activate a whistle or flashlight signal, and call out

Staying in place and signaling prevents further disorientation and makes it easier for the team to locate the lost member.

Question 15: Which debunking step should an investigator perform when a client reports cold spots in a specific room?

Seal the room and perform an EVP session
Ask the client to leave and not return to the room
Check for drafts, HVAC vents, window gaps, and use a thermal camera to map temperature distribution before attributing it to paranormal causes (Correct answer)
Immediately classify the cold spot as a paranormal energy drain

Correct answer: Check for drafts, HVAC vents, window gaps, and use a thermal camera to map temperature distribution before attributing it to paranormal causes

Cold spots should first be investigated for mundane sources such as HVAC vents, drafts, or thermal bridging using a thermal camera before any paranormal attribution is considered.

Question 16: During blind EVP review, why are transcripts or verbal suggestions about what a recording supposedly says withheld from panel listeners?

To ensure the review panel cannot identify the investigation location
To comply with federal privacy laws regarding recorded voices
To prevent suggestion bias from causing listeners to hear the suggested words (Correct answer)
To protect intellectual property rights of the capturing investigator

Correct answer: To prevent suggestion bias from causing listeners to hear the suggested words

Priming listeners with a suggested phrase dramatically increases the likelihood they will hear that phrase due to cognitive suggestion bias, invalidating the review.

Question 17: What is 'matrixing' in the context of video evidence review?

The brain's tendency to find familiar shapes (like faces) in random visual patterns such as shadows or textures (Correct answer)
A method of converting low-resolution video to higher resolution using AI upscaling
Overlaying a measurement grid on footage to track the movement of anomalies
Splitting a video frame into quadrants for simultaneous multi-camera review

Correct answer: The brain's tendency to find familiar shapes (like faces) in random visual patterns such as shadows or textures

Matrixing is the human brain's propensity to recognize familiar shapes, particularly faces, within random patterns; this can lead investigators to misidentify shadows or textures as apparitions.

Question 18: When using a digital voice recorder for EVP capture, why should investigators avoid whispering?

Whispering reduces battery life significantly
Whispering damages the microphone
Whispers can be misidentified as EVPs during review (Correct answer)
Whispering creates electromagnetic interference

Correct answer: Whispers can be misidentified as EVPs during review

Whispers are acoustically similar to EVP voices and can be mistakenly logged as paranormal audio evidence.

Question 19: When a follow-up investigation is warranted, what should the case file document about the decision?

Client approval signature only
The rationale for the follow-up, specific questions to be answered, and recommended equipment or techniques (Correct answer)
Only the date of the follow-up
The names of investigators who declined to participate

Correct answer: The rationale for the follow-up, specific questions to be answered, and recommended equipment or techniques

The case file should document the full rationale for the follow-up investigation, the specific questions it aims to answer, and any recommended equipment or protocol adjustments.

Question 20: A client reports lights flickering and believes it is a paranormal sign. What should an investigator do first?

Set up a full camera array and begin an EVP session immediately
Tell the client to replace all bulbs with LED lights
Inspect the electrical system, check for loose connections, aging wiring, or a failing ballast before considering paranormal causes (Correct answer)
Document it as confirmed paranormal activity

Correct answer: Inspect the electrical system, check for loose connections, aging wiring, or a failing ballast before considering paranormal causes

Flickering lights should first be evaluated for electrical causes such as loose connections, aging wiring, or failing bulb ballasts before any paranormal interpretation is entertained.

Question 21: Which buddy system rule is considered best practice for paranormal investigations?

Investigators may work alone in well-lit areas
Each investigator must always have at least one partner within visual or verbal contact (Correct answer)
Buddy pairs must stay within 50 feet of each other at all times
Buddies should separate to cover more ground efficiently

Correct answer: Each investigator must always have at least one partner within visual or verbal contact

Maintaining visual or verbal contact ensures immediate assistance if a team member is injured or incapacitated.

Question 22: When should an investigator update a case file after the initial investigation visit?

Whenever new evidence is analyzed, follow-up visits occur, or client feedback is received (Correct answer)
Only when submitting to a paranormal database
Never — the file is finalized after the first visit
Only if the client pays for additional reporting

Correct answer: Whenever new evidence is analyzed, follow-up visits occur, or client feedback is received

Case files are living documents that should be updated with any new evidence analysis, follow-up visit data, or significant client communications to ensure accuracy.

Question 23: When timestamping video evidence, why is syncing all cameras to a single time reference critical?

It allows cross-referencing of anomalies across multiple cameras to confirm or debunk them (Correct answer)
It prevents frame rate drift from overheating sensors
It ensures all IR illuminators activate simultaneously
It reduces file size when footage is compiled

Correct answer: It allows cross-referencing of anomalies across multiple cameras to confirm or debunk them

A shared time reference allows investigators to determine whether an anomaly captured on one camera corresponds to anything on other cameras at the exact same moment.

Question 24: What is the purpose of including a 'methodology' section in a paranormal investigation report?

To list all locations visited by the team
To explain the client's backstory in detail
To list the team's personal beliefs
To describe the techniques, equipment, and protocols used so findings can be evaluated and replicated (Correct answer)

Correct answer: To describe the techniques, equipment, and protocols used so findings can be evaluated and replicated

The methodology section documents all techniques, equipment settings, and protocols so that the investigation's scientific rigor can be evaluated and results potentially replicated.

Question 25: In CPI reporting standards, what does the term 'corroborating evidence' mean?

Duplicate files of the same recording
Two or more independent pieces of evidence that support the same anomalous event or finding (Correct answer)
Client testimony that agrees with the investigator's opinion
Evidence collected by a second investigation team at a different location

Correct answer: Two or more independent pieces of evidence that support the same anomalous event or finding

Corroborating evidence refers to two or more independent data points—such as an EMF spike coinciding with an EVP capture—that support the same anomalous event.

Question 26: Which statement BEST describes how investigators should use full-spectrum photography in relation to other investigation tools?

Photographs taken with full-spectrum cameras are admissible as legal evidence without additional review
Full-spectrum photography is definitive proof on its own and does not require corroborating evidence
Full-spectrum photography should be one component of a multi-instrument approach, with anomalies requiring corroboration from EMF, temperature, or audio data (Correct answer)
Full-spectrum cameras replace the need for video during an investigation

Correct answer: Full-spectrum photography should be one component of a multi-instrument approach, with anomalies requiring corroboration from EMF, temperature, or audio data

CPI methodology treats no single instrument as conclusive; full-spectrum anomalies gain credibility only when corroborated by simultaneous readings from other instruments.

Question 27: How should inconclusive evidence be presented in a final report?

Attribute it to paranormal activity by default
Label it as definitive paranormal evidence to add value
Omit it entirely to avoid confusing the client
Present it as inconclusive, describe the capture conditions, and explain why a determination could not be made (Correct answer)

Correct answer: Present it as inconclusive, describe the capture conditions, and explain why a determination could not be made

Inconclusive evidence should be clearly labeled as such, with capture conditions documented and an explanation of why a definitive determination was not possible.

Question 28: What is the 'ideomotor effect' and how can it influence paranormal investigation results?

A type of infrasound resonance in old buildings
A camera lens distortion that creates orb artifacts
A method of mapping electromagnetic hotspots
Unconscious muscular movements that cause devices like dowsing rods or talking boards to move without conscious intent (Correct answer)

Correct answer: Unconscious muscular movements that cause devices like dowsing rods or talking boards to move without conscious intent

The ideomotor effect causes unconscious muscle movements that can make dowsing rods, pendulums, or Ouija boards appear to respond independently, producing misleading paranormal results.

Question 29: What is the primary purpose of logging GPS coordinates and timestamps in a paranormal investigation data record?

GPS data is required by CPI certification standards
To track investigator movements for safety
To enable precise correlation of readings with specific locations and times for repeatable analysis (Correct answer)
To satisfy insurance requirements

Correct answer: To enable precise correlation of readings with specific locations and times for repeatable analysis

Precise location and time stamps allow investigators to cross-reference multiple data streams and identify whether anomalies cluster spatially or temporally.

Question 30: Which type of evidence should be labeled with GPS coordinates or exact room location in the case file?

Only evidence reviewed by the lead investigator
All physical, photographic, and digital evidence collected during the investigation (Correct answer)
Only evidence captured after midnight
Only audio evidence

Correct answer: All physical, photographic, and digital evidence collected during the investigation

Every piece of evidence should be labeled with its precise capture location so findings can be accurately contextualized and independently verified.

Question 31: An EVP recorded in an abandoned building contains a voice speaking a language the investigator does not recognize. What is the most methodologically sound next step?

Discard it as unintelligible
Have the recording reviewed by a native speaker of the suspected language to verify content (Correct answer)
Assume it is speaking in tongues and classify as supernatural
Immediately classify it as Class A and publish to social media

Correct answer: Have the recording reviewed by a native speaker of the suspected language to verify content

Expert linguistic verification by a native speaker is essential before drawing conclusions about the content or meaning of a voice in an unfamiliar language.

Question 32: Why do some CPI investigators use a 590 nm full-spectrum cut-on filter instead of a 720 nm filter?

720 nm filters are incompatible with modified DSLRs
590 nm filters are cheaper and more widely available
590 nm blocks all UV light to prevent lens flare
590 nm captures a blend of near-visible red, infrared, and partial UV, offering richer tonal variation for anomaly detection (Correct answer)

Correct answer: 590 nm captures a blend of near-visible red, infrared, and partial UV, offering richer tonal variation for anomaly detection

The 590 nm cut-on point retains near-visible red tones in addition to IR, providing more color information than a pure IR filter and making certain anomalies easier to distinguish.

Question 33: Which logging interval is generally recommended for continuous environmental baseline data to capture transient anomalies without overwhelming storage?

Every 5–10 seconds (Correct answer)
Every 60 seconds
Once per minute is always sufficient
Every 10 seconds

Correct answer: Every 5–10 seconds

A 5–10 second logging interval balances data resolution for capturing brief transient events against manageable file sizes during multi-hour investigations.

Question 34: Why is it important to document the temperature and humidity conditions during video evidence collection?

Temperature and humidity data are required by all paranormal certification bodies to validate evidence
Condensation mist, fog breath, or thermal anomalies can create visual effects that are mistaken for apparitions (Correct answer)
IR cameras require humidity calibration to function accurately
Low humidity causes IR illuminators to flicker, creating video artifacts

Correct answer: Condensation mist, fog breath, or thermal anomalies can create visual effects that are mistaken for apparitions

Breath condensation in cold air, water vapor, and temperature-related visual effects can appear on camera as mist or moving shapes that mimic apparitions, so environmental data allows reviewers to rule out these causes.

Question 35: What is 'confirmation bias' and how should a CPI investigator guard against it?

A bias toward expensive investigation equipment
A tendency to disbelieve all witness reports
A preference for nighttime investigations over daytime ones
The tendency to favor information that confirms pre-existing beliefs, guarded against by applying consistent skeptical analysis to all evidence (Correct answer)

Correct answer: The tendency to favor information that confirms pre-existing beliefs, guarded against by applying consistent skeptical analysis to all evidence

Confirmation bias leads investigators to accept evidence supporting paranormal explanations while dismissing contrary data, and it is countered by applying rigorous skeptical analysis equally to all evidence.

Question 36: What does a 'full spectrum' camera capture that a standard consumer video camera does not?

Higher frame rates for slow-motion paranormal event replay
Electromagnetic field data embedded in each video frame
360-degree panoramic footage without a blind spot
Near-UV and near-IR light outside the visible spectrum, which some investigators believe may reveal anomalies (Correct answer)

Correct answer: Near-UV and near-IR light outside the visible spectrum, which some investigators believe may reveal anomalies

Full spectrum cameras have had their IR-blocking filter removed, allowing them to record near-ultraviolet and near-infrared light that standard cameras block, which some paranormal investigators believe may capture phenomena invisible to the naked eye.

Question 37: How should an investigator handle a witness who becomes increasingly convinced of paranormal activity and emotionally dependent on the investigation team?

Assign a team member to act as the client's personal paranormal advisor
Continue the investigation indefinitely to address all concerns
Gently redirect the client to appropriate mental health resources if needed, and avoid reinforcing unfounded paranormal conclusions that increase distress (Correct answer)
Encourage the dependency to maintain client engagement

Correct answer: Gently redirect the client to appropriate mental health resources if needed, and avoid reinforcing unfounded paranormal conclusions that increase distress

Ethical investigators recognize when a client's distress warrants professional mental health support and avoid reinforcing unfounded paranormal conclusions that may worsen psychological harm.

Question 38: How should still images be evaluated during evidence analysis?

By using filters
By skipping blurry images
By comparing to baseline images (Correct answer)
By zooming in repeatedly

Correct answer: By comparing to baseline images

Images should be reviewed for anomalies, validated against baseline photos, and checked for camera artifacts.

Question 39: What effect does a very wide aperture (e.g., f/1.8) have on potential orb artifacts in full-spectrum investigation photography?

Wide apertures cause the sensor to register more IR radiation
Wide apertures block UV light more effectively than narrow apertures
Wide apertures eliminate orbs by increasing depth of field
Wide apertures create very shallow depth of field, making out-of-focus dust particles appear as large, soft orbs (Correct answer)

Correct answer: Wide apertures create very shallow depth of field, making out-of-focus dust particles appear as large, soft orbs

A wide aperture produces an extremely shallow depth of field; airborne particles just in front of or behind the focal plane appear as large, soft, glowing circles (bokeh orbs) rather than sharp specks.

Question 40: What is 'chromatic aberration' and why is it particularly relevant in full-spectrum investigation photography?

It is the failure of a lens to focus UV, visible, and IR wavelengths at the same focal plane, producing color fringing in full-spectrum images (Correct answer)
It refers to the color shift introduced when switching from RAW to JPEG
It is sensor overheating that creates rainbow artifacts only in full-spectrum mode
It is a white balance error unique to modified cameras

Correct answer: It is the failure of a lens to focus UV, visible, and IR wavelengths at the same focal plane, producing color fringing in full-spectrum images

Chromatic aberration is more pronounced in full-spectrum photography because UV, visible, and IR light refract differently through glass, creating colored halos or fringing around subjects.

Question 41: What is the primary ethical obligation of a CPI professional when a conflict of interest arises during audio & video evidence review activities?

Resolve the conflict privately without informing stakeholders
Ignore the conflict if it does not directly affect the current task
Disclose the conflict to all relevant parties and recuse from the decision if necessary (Correct answer)
Proceed while favoring the outcome that benefits the professional personally

Correct answer: Disclose the conflict to all relevant parties and recuse from the decision if necessary

The primary ethical obligation when a conflict of interest arises in audio & video evidence review is to disclose it to all relevant parties and, if necessary, recuse from the decision. This maintains professional integrity and stakeholder trust.

Question 65: During evidence review, an EVP appears to directly answer a question asked by an investigator two seconds earlier. This type of EVP is often categorized as which specialized subtype?

Residual EVP
Intelligent or interactive EVP (Correct answer)
Imprinted EVP
Ambient EVP

Correct answer: Intelligent or interactive EVP

An EVP that responds contextually to a question is classified as intelligent or interactive, suggesting real-time awareness rather than a residual loop.

Question 66: When multiple investigators use separate handheld EMF meters in the same area simultaneously, what data logging problem can arise?

Handheld meters cannot be used simultaneously under CPI rules
The devices themselves emit EMF that can cross-contaminate each other's readings (Correct answer)
Multiple meters always improve accuracy through averaging
The meters will cancel each other's readings

Correct answer: The devices themselves emit EMF that can cross-contaminate each other's readings

Electronic devices including EMF meters emit their own electromagnetic fields, which can cause artificially elevated readings in adjacent meters when used in close proximity.

Question 67: An investigator uses an unmodified smartphone with a 'full-spectrum' app during an investigation. How should these results be treated?

The app bypasses hardware limitations and enables genuine UV capture
Smartphone sensors are equally sensitive to UV and IR as modified DSLRs
Smartphones capture IR more efficiently than DSLRs due to smaller sensor size
With skepticism, because smartphone sensors retain strong IR-cut filters and cannot truly capture full-spectrum data (Correct answer)

Correct answer: With skepticism, because smartphone sensors retain strong IR-cut filters and cannot truly capture full-spectrum data

Smartphone sensors include permanently integrated IR-cut filters that cannot be removed, so no app can enable true full-spectrum capture regardless of marketing claims.

Correct answer: The documented history of a document's origin, custody, and chain of ownership

Provenance refers to the documented history of a document's origin and custody, which helps researchers assess its authenticity and reliability as historical evidence.

Question 86: What is 'stone tape theory' and why is it relevant to evidence analysis?

A theory that stone buildings produce false EMF readings
A method for recording EVPs using mineral-based microphones
A disproven theory with no relevance to modern investigation
A hypothesis that building materials can record and replay emotional or traumatic events (Correct answer)

Correct answer: A hypothesis that building materials can record and replay emotional or traumatic events

Stone tape theory proposes that certain materials may absorb and later replay psychic impressions, influencing how investigators interpret residual hauntings.

Question 87: Which information should be included in the initial case intake form for a paranormal investigation?

Only the client's name and address
Social media handles of all witnesses
Client contact info, reported activity description, location history, and witness names (Correct answer)
Investigator credentials and equipment list only

Correct answer: Client contact info, reported activity description, location history, and witness names

The initial intake form must capture client contact details, a full description of reported activity, location history, and witness information to establish a complete baseline.

Ask the client to remove the person before resuming
Continue filming since the investigation is already underway
Blur the person's face in post-production and continue

Correct answer: Stop recording until the person is informed and consents, or leaves the area

In all-party consent (two-party) states, recording must stop or the unconsenting individual must leave before recording can legally resume.

Question 101: During video review, a shadow anomaly is observed crossing a wall. Which control condition BEST rules out a natural explanation?

Rewatching the footage with the lights on
Applying a brightness filter to the anomalous frames
Converting the video to a higher frame rate
Checking simultaneous footage from a second camera covering the same area (Correct answer)

Correct answer: Checking simultaneous footage from a second camera covering the same area

A second synchronized camera provides an independent vantage point; if the shadow appears on one camera but not the other, it suggests a camera artifact rather than a real phenomenon.

Question 102: When writing conclusions in a CPI report, which phrasing is most appropriate?

'No investigation is needed; the client is imagining things.'
'Evidence collected is consistent with anomalous activity; natural explanations have been considered and noted.' (Correct answer)
'This location is definitively haunted by multiple entities.'
'We found nothing and the client should move out.'

Correct answer: 'Evidence collected is consistent with anomalous activity; natural explanations have been considered and noted.'

Professional conclusions should state that evidence is consistent with anomalous activity while acknowledging that considered natural explanations were also evaluated, avoiding absolute claims.

Question 103: Which common household appliance is most likely to cause false positive EMF readings during a paranormal investigation?

It is a frequency used to calibrate EMF meters before field use
It is a government-assigned radio frequency band that investigators must avoid
It describes the resonance frequency of human bones, relevant to physical sensations during investigations

Correct answer: It is the Earth's natural electromagnetic resonance (~7.83 Hz) used as a background reference that unusual deviations may warrant investigation

The Schumann Resonance is Earth's natural ELF background (~7.83 Hz); some investigators monitor deviations from this baseline as a potential environmental anomaly marker.

Question 111: An investigator finds historical death records matching a client's reported haunting. How should this information be used?

Published without client consent to share historical findings
Presented to the client as proof of paranormal activity
Incorporated directly into the evidence score
Used to build contextual background, but not treated as evidence of current paranormal phenomena (Correct answer)

Correct answer: Used to build contextual background, but not treated as evidence of current paranormal phenomena

Historical research provides context and may explain client experiences, but past events alone do not constitute evidence of current paranormal activity.

Question 112: Which practice best ensures site protocol compliance when a new investigator joins an established CPI team for the first time?

Allow them to shadow experienced members without a formal introduction
Review protocols verbally at the start of the investigation only if time permits
Assign them to base camp duties only for the first three investigations
Provide a written safety briefing document and have them sign acknowledgment before the investigation (Correct answer)

Correct answer: Provide a written safety briefing document and have them sign acknowledgment before the investigation

A written briefing with signed acknowledgment ensures the new member receives complete safety information and creates a record of their awareness.

Question 113: When investigating an abandoned building, what is the FIRST safety check a team should perform before entering?

Set up a central command station outside
Test all electronic equipment for battery life

The Wi-Fi channel in use at the site
The exact GPS coordinates of each room
Ambient air temperature throughout the site (Correct answer)
The number of occupants who used the building the previous day

Correct answer: Ambient air temperature throughout the site

Recording ambient air temperature establishes a reference point so investigators can judge whether detected thermal variations are significant deviations rather than normal room-to-room differences.

Question 119: The 'Human Agency Theory' of haunting phenomena differs from spirit-based theories in that it attributes experiences to:

Psychological factors, perception errors, and environmental causes rather than actual entities (Correct answer)
Collective unconscious archetypes manifesting physically
Government electromagnetic experiments affecting civilian populations
Living psychics projecting thought-forms into locations

Correct answer: Psychological factors, perception errors, and environmental causes rather than actual entities

Human Agency Theory holds that paranormal experiences result from misperception, psychological states like grief or suggestion, environmental factors, and cognitive biases rather than actual spirits.

Question 120: The 'Philip Experiment' conducted in Toronto (1972-1977) was significant because it:

Provided the first laboratory proof of life after death
Proved that EVP recordings contain genuine spirit communications
Demonstrated that groups could apparently create paranormal phenomena around a fictional, invented character (Correct answer)
Established the first controlled protocol for detecting residual hauntings

Correct answer: Demonstrated that groups could apparently create paranormal phenomena around a fictional, invented character

The Philip Experiment showed that a group could generate apparent poltergeist-like phenomena and table-rapping responses centered on a fictional ghost they had entirely invented, supporting psychokinesis over spirit theories.

Question 121: Which wavelength range does a full-spectrum camera capture that a standard camera cannot?

UV below 400 nm and IR above 700 nm (Correct answer)
400–700 nm visible only
Only infrared above 900 nm

Question 122: Which factor most significantly affects the reliability of a witness's paranormal account?

Whether the witness has a college degree
The witness's age and physical fitness
The number of social media followers the witness has
The time elapsed between the experience and when it was reported, along with the witness's emotional state (Correct answer)

Correct answer: The time elapsed between the experience and when it was reported, along with the witness's emotional state

Memory degrades and becomes susceptible to suggestion over time, so the elapsed time between experience and report—combined with emotional state—significantly impacts account reliability.

Question 123: What does 'chain of custody' mean when applied to paranormal investigation evidence?

The order in which investigators enter a location
The hierarchy of authority within an investigation team
A documented record of who handled evidence and how it was stored from collection to review (Correct answer)
A legal term not applicable to paranormal research

Correct answer: A documented record of who handled evidence and how it was stored from collection to review

Maintaining chain of custody ensures that evidence has not been tampered with or contaminated, preserving its integrity and credibility for analysis.
