An important part of structuring a magic routine is to have methods that cancel each other out. ACRs are a good way to study this concept that greats like Teller utilize. Even if a spectator can see your pass, the DL, tilt, top change, and side steal will still fool them. Using those different methods to create the same effect allows you to cancel out any one method the spectator might think of.
Mentalism usually uses this concept on an even subtler level. I'm not a mentalist, but from what I've seen, a good structure for a billet reading is to secretly obtain the information written on the billet and then add to it. If the name of a person they know, most mentalists probably won't just say the name and stop right there. They cold read and try to create the appearance of knowing their physical and personal characteristics. Then they say the name.
If a spectator claims that the mentalist read the billet, he will seem wrong because the mentalist described the person, not just the name. If they say the performer just guessed, then the apparent accuracy of the description and the fact that the name was correctly revealed cancels out that possibility. The physical and psychological methods cancel each other out.
With my magic, I try (key word: try) to combine this type of thinking along with likable, honest presentations to make the actual method unimportant and/or impossible to figure out.
