Is there any way to get more psychological forces like this:
* Say a number between 1 and 5." And they "always" say 3 and if not: they say 4 and if I say: "lower" they say 2 and if I then say: "higher" they say 3.
or
* With cards. I lay down one card at the time and after 5 cards I say: Say stop any time you like. And they almost every time stay on 10!

I would like to have more techniques like this as I really find them very useful!
Thank You!
