ELF Modulation

ELF (Extremely Low Frequency, 3-30 Hz) mind modulation theories claim certain frequencies can entrain brainwaves, alter mood, disrupt cognition, or implant subconscious suggestions when broadcast at population scale. Frequencies overlap with Schumann resonances and brainwave bands (delta, theta, alpha), suggesting natural biological receptivity.

Reported Claims and Sources

Claims involve HAARP, GWEN (Ground Wave Emergency Network) towers, cell towers, and power grids broadcasting behavior-control frequencies. Soviet 'Woodpecker' signal (10 Hz over-horizon radar, 1976-89) generated conspiracy theories about psychological warfare. Alleged effects include induced anxiety, aggression suppression, memory disruption, and sleep interference. Some attribute mass behavioral patterns to ELF manipulation.

Scientific Assessment

Scientific consensus

ELF can affect biology (power line workers report symptoms), but only at high field strengths unavailable from broadcast towers. Brainwave entrainment exists (binaural beats) but requires focused exposure. Atmospheric ELF propagates poorly and can't carry complex information. Most claims conflate real ELF research (submarine communication) with unfeasible mind control. Nevertheless, legitimate bioelectromagnetic effects, documented military interest in non-lethal weapons, and MKULTRA precedent sustain ELF mind modulation concerns. The category bridges real physics, verified biological sensitivity, and speculative behavioral control—making it more plausible than purely fictional psychotronics.
