Sorry if this is a dark subject, but: A major faction in a story that I am working on relies on psychological torture to recruit new soldiers. It has a post-apocalyptic (political) setting, and they torture the opposing survivors to join their army. They use psychological torture—why would they injure their soon-to-be soldiers?—to make them feel as a unit with the other soldiers. Now I found a few methods of torture, like putting people in small boxes with nothing in sight but pure light, shaving everyone’s head and dressing them the same (to remove their individuality)… but that’s about it. The internet doesn't normally give you too much information on how to torture people. That’s why I am asking all of you, any “neat” methods of psychological torture?
