Daniel Krawisz had a great video explaining on how to think independently. Here are two tips to get out of a cult:
Assume you're in a cult and you have to figure out what it is. Cult members are unaware they are in a cult, so if you are stuck in one to get out you must begin with the assumption that you are in one.
Embrace "evil." Cults paint the escape path from them as "evil" to keep their members locked in (i.e. the forbidden fruit) So you should at least entertain ideas that are forbidden within your circles, for they may be painted as evil to prevent you from seeing the way out.
