Open Prediction by Pitata, Peter Turner, PigCake, and Marc Spelmann

Effect

The Open Prediction is a classic card magic effect. A spectator shuffles and cuts a deck of cards. The magician then makes a prediction, often writing it down or setting a card aside. The spectator deals through the deck face-up, stopping at a card of their choice. This card matches the magician's earlier prediction exactly. The effect appears to be a perfect demonstration of foresight and control over random events.

Full details

The Open Prediction is a foundational plot in card magic and mentalism. It involves a spectator handling the deck extensively, which creates a strong sense of fairness. The magician's prediction is made openly, before the final card is revealed. Methods for achieving this effect vary. Some use specific decks, like the Mantis marked deck, which allows the magician to secretly identify a card. Other methods rely on statistical principles and psychological influence. For example, an "indicator card" can be used to subtly guide when the spectator stops dealing. More advanced setups, like the Ultra Prediction Table, incorporate technology such as Bluetooth printers to produce a physical prediction instantly. The goal of all methods is to create the illusion that the magician knew the outcome from the start.

Who should consider the trick

The Open Prediction is suitable for magicians at different skill levels. Beginners can find simple methods that require little sleight of hand. These are ideal for those new to card magic. Intermediate performers may appreciate methods that use psychological influence and audience management. Professionals often use more complex versions of the effect for stage or close-up performances. Mentalism performers will find the Open Prediction fits well into their acts. It is a versatile effect that can be adapted for various performing conditions.

Information on how difficult it is to perform

The difficulty of the Open Prediction depends on the method chosen. Basic versions are not technically demanding. They focus on presentation and psychological timing. As Peter Turner notes, even a simple method can be highly effective. More advanced techniques may require practice with shuffling and cutting to control card positions. Performers must also develop skill in guiding spectator choices without being obvious. Devices like the Ultra Prediction Table reduce technical difficulty by automating part of the process. Overall, a performer can start with an easy method and progress to more challenging variations as their skill increases.

What magicians say

Magicians highlight the power and versatility of the Open Prediction. Peter Turner calls it "one of the most impressive feats in all of magic and mentalism." He explains that methods can range from basic to complex, using both psychology and mechanics. Craig Petty includes Open Prediction in discussions about professional routining and handling spectators. He advises on maintaining a positive atmosphere, which is key for this effect. PigCake emphasizes that audience perception matters more than perfect technique. He shares that watching others perform the trick can provide new insights, stating magicians should "always say yes" to being shown a trick. Reviewers from Saturn Magic describe the Ultra Prediction Table as a "clean and effective method" that offers a "seamless integration" for stage use. SeanDevine points out that while simple methods can fool laypeople, magicians familiar with marked decks might detect the method. Overall, the consensus is that the Open Prediction is a strong effect with many approaches available for performers.
