Words like “mind control” and “brainwashing” get tossed around, but it is a very real science and a very dangerous game that former CIA operative and now conservative talk show host Buck Sexton calls by its scientific name of “menticide,” the murder of the mind.

Psychological attacks are real, and the concept of menticide dates to a Dutch psychologist who studied how totalitarian governments control the thoughts of their populations. Joost Meerloo witnessed and studied the way Josef Stalin, Vladimir Lenin, and Mao Zedong used the insights from Pavlov’s experiments on dogs against people. His most famous work is called The Rape of the Mind.
