Misdirection of Attention: “Pay attention or you’ll miss the trick.” To understand how magicians manipulate their audience, we need to talk about attention. Attention has been crucial for human survival, helping our ancestors focus on tasks while staying aware of dangers. Given the numerous potential threats in nature, human attention is naturally limited and divided, and this weak spot is exactly the thing a magician needs to fool us. Magicians often misdirect your attention while performing a trick. For example, have you ever been asked to hold an object tightly during a performance? This directs the audience member’s full attention to that task, allowing the trick to happen elsewhere. They could also use external triggers, like a bright flash or a loud noise, to momentarily control the audience's attention.

Misdirection of Memory: Have you ever been asked to “Remember this card” during a magic trick? While it may seem easy at first, it quickly becomes challenging when you’re also asked to shuffle cards or watch the magician closely.

According to the Multi-store Model of Memory, our short-term memory has limited capacity. To keep a card or number in short-term memory, we rely on a rehearsal loop, repeating it sub-vocally like “Queen of Hearts, Queen of Hearts.” Without rehearsal, the information fades quickly, usually within 18 seconds. By asking you to memorize something while performing another task, magicians divide your mental resources, making it harder to figure out the trick. Additionally, our memory recall depends on the sequence of events. This is known as the “recency effect,” meaning the most recent items are most easily recalled. Magicians exploit this by delaying the trick, ensuring the method is quickly forgotten if any member seems to have figured it out.

Perception vs. Reality: Magicians also exploit a concept called ‘inductive reasoning,’ where observations or facts are used to make educated guesses. For those interested in behavioural economics, inductive reasoning is what generates systematic biases like availability bias! Because humans exhibit bounded rationality, adequately constructing hypotheses about what happened in a magic trick is difficult. According to Tversky and Kahneman, we reason based on the amount of information available to us while ignoring information that is less available. The audience will often underestimate the amount of effort put into an effect or simply lack the information as to how this effect has come to be, therefore they will carry around assumptions bounded to ‘logically possible’ guesses as to how the trick works – in most cases, it’s simply magic.
