When reviewing video footage for paranormal anomalies, what is the recommended playback method for the most thorough analysis?
Answer: Watch in real-time, then review any anomalous sections frame-by-frame
Real-time viewing catches timing relationships between events, while frame-by-frame review of anomalous sections reveals details invisible at normal speed.
What is 'stone tape theory' and why is it relevant to evidence analysis?
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.
Which of the following best describes a 'false positive' in paranormal evidence analysis?
Answer: A reading or anomaly that appears paranormal but has a verifiable natural explanation
A false positive is any piece of apparent evidence that is later explained by a natural, mundane cause.
Why should investigators avoid using wireless communication devices (walkie-talkies, cell phones) near active audio recorders?
Answer: Radio frequency interference can create audio artifacts that mimic EVP voices
RF interference from radios and mobile devices creates clicking, buzzing, or voice-like artifacts on audio recordings that can be mistaken for EVPs.
An investigator proposes sharing a client's location and personal haunting details on social media with the client's implicit, assumed permission. What is the correct protocol?
Answer: Obtain explicit written consent before sharing any identifying information
Explicit written consent is required before sharing any location-specific or personal information; assumed permission is not sufficient.
What is the significance of simultaneously capturing an EMF spike and an EVP at the same location and time?
Answer: It demonstrates corroborating evidence across two independent data types, strengthening the anomaly's credibility
Simultaneous anomalies across independent measurement types (EM field and audio) represent stronger, corroborated evidence than either alone.
After an investigation, how long should raw evidence files be retained before deletion, according to best practices?
Answer: At minimum until the case is closed and the client has received and acknowledged the report
Evidence should be retained at least until the case is formally closed and the client has received the final report, ensuring recourse if questions arise.
