Investigation methodology

OBSERVE → DOCUMENT → TEST → ANALYZE → ATTEMPT TO EXPLAIN → REPORT

  1. 01

    Observe

    Describe what you notice.

  2. 02

    Document

    Preserve the context and record.

  3. 03

    Test

    Use controls and repeat the test.

  4. 04

    Analyze

    Compare independent records.

  5. 05

    Attempt to explain

    Test conventional explanations.

  6. 06

    Report

    Share findings and limitations.

01 / Observe

Describe what happened without naming a cause. Separate a witness account, direct investigator perception, and a device output. Record the setting and who was present.

02 / Document

Record exact times and time zones, location, instrument settings and units, participants, environmental conditions, and original file IDs. Preserve the ordinary events around a candidate event.

03 / Test

Choose a conventional hypothesis and state what you would expect to observe if it were correct. Use a control condition and repeat the procedure when safe and practical. Record failures and inconclusive results.

04 / Analyze

Compare independent records and reviewers. Check timing, instrument limits, artifacts, handling, expectations, and source integrity. Analyze copies and retain untouched originals.

05 / Attempt to explain

Test electrical interference, radio broadcasts, acoustics, airflow, reflections, animals, equipment behavior, and perceptual effects where relevant. Failure to reproduce one explanation does not eliminate all ordinary causes.

06 / Report

State the question, procedure, results, tested explanations, classification, and remaining limits. Explain what evidence could change the conclusion. Keep personal experiences distinct from measured findings.
