Equivocation (or the magician’s choice) is a verbal technique by which a magician gives an audience member an apparently free choice, but frames the next stage of the trick in such a way that each choice has the same end result. For example, the performer may deal two cards to the table and ask a spectator to select one: if the spectator chooses the card on the left, the performer will say something like “you keep this card, I’ll take the remaining card”. If the spectator chooses the card on the right, the performer will take that card. Thus, the choice of which card to use is really made by the magician.

During the show, mentalist will select those people as volunteers and with the use of some clever presentation mentalist will use those clues to perform some super mentalism effects.
