People who are afraid of “psyops” or mass psychological manipulation really miss one major point...psychology is absolutely useless. Anyone who studies it even vaguely realises that nobody has a clue what’s going on and that the field contains oceans of bullshit.
Psychology is not like engineering w/ predictable results. As someone observed, “If psychologists actually understood the mind , we would be terrified of them. They would be like small gods.” Most psychologists are about as good as your grandmother at getting humans—many worse.
