Not Science Fiction: The Rise of Weapons That Target the Human Mind

Researchers at Bradford University in the UK have raised serious concerns about the weaponization of neuroscience, pointing to tools that could soon manipulate thoughts, emotions, and actions on a massive scale. In their latest book, Dr. Michael Crowley and Professor Malcolm Dando detail how nations have pursued these capabilities for decades, and why the time to act is running out.

Governments like the US, China, Russia, and the UK began exploring central nervous system (CNS)-acting agents back in the 1950s. The US military, for instance, developed a compound called “BZ,” which induces hallucinations and delirium. They produced over 60,000 kilograms of it and even tested a 340-kilogram cluster bomb, though it was never used in Vietnam.

China has showcased a ‘narcosis-gun’ designed to deliver incapacitating chemicals from a distance. The only known battlefield deployment came during the 2002 Moscow theater siege, where Russian forces pumped in a fentanyl-based gas, resulting in the deaths of 120 hostages and lasting health problems for survivors.

These examples show a pattern of states pushing boundaries. And as much as we’d like to hope that these are for extreme defensive uses only, history proves men in every technologically advanced country invariably turn their research into practical offensive weapons.

“We are entering an era where the brain itself could become a battlefield,” Dando states. “The tools to manipulate the central nervous system – to sedate, confuse, or even coerce – are becoming more precise, more accessible, and more attractive to states.”

Advances in understanding the brain’s “survival circuits”—those governing fear, sleep, aggression, and decision-making—stem from efforts to treat disorders like PTSD or Alzheimer’s. Yet this same knowledge opens doors to abuse.

“The same knowledge that helps us treat neurological disorders could be used to disrupt cognition, induce compliance, or even in the future turn people into unwitting agents,” Dando explains. “That’s the dual-use dilemma we face.”

A major issue lies in international treaties. The Chemical Weapons Convention bans harmful chemicals in warfare but carves out exceptions for law enforcement, creating loopholes that could greenlight these programs.

“There are dangerous regulatory gaps within and between these treaties,” Dando warns. “Unless they are closed, we fear certain States may be emboldened to exploit them in dedicated CNS and broader incapacitating agent weapons programmes. We must act now to protect the integrity of science and the sanctity of the human mind.”

Crowley and Dando are heading to The Hague to push for reforms, echoing calls from other experts who see this as a ‘wake-up call’ for global action.

Looking ahead, the threats extend beyond chemicals. Psycho-electronic devices, using electromagnetic fields to influence the mind, trace back to the CIA’s MKUltra program, which ran from 1953 and involved LSD experiments on unwitting subjects. While officials dismissed it as a Cold War relic after congressional hearings in 1977, whispers persist of similar efforts continuing in shadows today. Combined with AI, these could enable cyborg enhancements for soldiers, granting superhuman senses or unbreakable focus—but at what cost to free will?

As one recent analysis notes, non-lethal brain-modifying tools are advancing quickly, risking attacks on human consciousness itself. The potential for states or rogue actors to wield such power demands vigilance, lest personal autonomy become just another casualty in the quest for control.
