Think of a Card. Any card. Name it out loud now.... *DO NOT SCROLL DOWN*
Was it a 4 of Clubs?
I usually have success with psychologically forcing the four of clubs, also the 2 of hearts. d+M has some very good psychological forces in ONE that involve telling a story that has some implications. Anate is a clever principle, but only works1 or 2/5 times (3/11 for me so far though... )
I don't think there is a set way to psychologically force a card, although there are some good methods in the books you listed, and there are some good ones in Benjamin Earl's Past Midnight set (DISC 3).
I have to agree the 7 of Hearts taught on Derren's lecture DVD is rather effective.The most reliable one for me is Seven of Hearts. Derren Brown teaches it in his lecture Dvd. Incredibly reliable. A tip for when you invent your psychological forces. Try them out on Omegle.com. Ahaha. Removes any need for outs, as if you fail, you can simply leave the conversation.
Whichever route you go, just make sure you know what you're studying. And beware confusing presentation for reality.
I am curious what outs people use when performing physycological forces? I know Dee mentions LOKI but am interested in what other outs people use. If I perform Anate, I will sometimes preface it by this is the start of an experiment and if it does not hit go into something else (maybe Brown's Invisible Deal--a little risky because it is still not 100%). I just tell people that the Anate part was to get a feel for where they are coming from.
I love these forces because when they hit, the reaction is unbelievable. Always looking for some good outs. Thanks
