Dowsing may involve a physical phenomenon, not just ideomotoric reactions. Human responses during dowsing experiments correlated significantly with walking paths, suggesting radio frequency radiation interference.
Area of Science:
- Geophysics
- Human Physiology
- Electromagnetism
Background:
- Dowsing, the practice of locating underground resources, has traditionally been explained by ideomotoric movements.
- Previous studies often dismissed dowsing due to a lack of verifiable physical mechanisms.
Purpose of the Study:
- To re-analyze historical dowsing experiment results.
- To investigate potential physical phenomena underlying dowsing reactions.
- To explore the influence of radio frequency radiation on dowsing.
Main Methods:
- Re-analysis of recorded human reactions during dowsing field experiments.
- Comparison of dowsing reactions while walking versus in a moving, window-covered car.
- Correlation analysis of reaction points with environmental factors like radio tower proximity and wave incidence angle.
Main Results:
- Highly significant correlations were found between dowsing reaction points in a moving car and along a walking path.
- These correlations were not universal across all test locations.
- Results suggest a potential link between dowsing responses and man-made radio frequency radiation (FM radio, TV broadcasting).
Conclusions:
- The ideomotoric explanation for dowsing may be incomplete.
- Human bodies may absorb radio waves, leading to unconscious hand movements influenced by standing waves or multipath propagation.
- Environmental radio frequency radiation could have interfered with 20th-century dowsing experiments.

Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...

Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
