Environmental factors & evidence contamination
Real-world conditions can create, distort, or contaminate what people perceive as paranormal activity. This area sets out the major environmental factor groups, what the evidence does and does not support, and how each one is reviewed during a responsible investigation.

CO, CO₂, radon, and airborne contaminants can produce sensory effects that mimic paranormal experiences.

Sub-20 Hz infrasound and structural vibration can induce unease, dread, and visual anomalies without a perceptible source.

Elevated electromagnetic and radio-frequency fields are reviewed as potential biological and equipment-interference factors.

Thermal gradients, IR reflections, and optical interference can produce artefacts in photographic and video evidence.

Tectonic stress, fault proximity, building materials, and soil composition form the physical baseline for any site review.
