Sleights of Mind: the secrets of neuromagic

Last month, I blogged a fascinating profile of Apollo Robbins, a stage pickpocket with an almost supernatural facility for manipulating attention and vision to allow him to literally relieve you of your watch, eyeglasses, and the contents of your wallet without you even noticing it, even after you've been told that he's planning on doing exactly that.

The profile mentioned that Robbins had consulted on a book called Sleights of Mind, written by a pair of neuroscientists named Stephen L Macknick and Susana Martinez-Conde (a husband and wife team, who also hired science writer Sandra Blakeslee to help with the prose, to very good effect). Macknick and Martinez-Conde are working scientists who had a key insight: the way that magicians manipulate our blind spots, our attention, our awareness, our intuitions and our assumptions reveal an awful lot about our neurological functions. Indeed, conjurers, pickpockets, ventriloquists and other performers are essentially practicing applied neuroscience, working out ways to systematically fool our perceptions and make seemingly impossible things happen before our eyes.

The book is a marvellous read, a very well-balanced mix of summaries of published scientific insights into visual and attention systems; accounts of the meetings between illusionists and scientists that the authors organized; histories of magic tricks; exposure of psychic frauds and fakes; and a tale about the couple's quest to craft a neuroscience-based magic act that would gain them full membership to the exclusive Magic Castle in Los Angeles.

I really can't overstate the charm and delight of Sleights of Mind -- from the introduction to the extensive footnotes, it is a truly great popular science text on one of my favorite subjects. The accompanying website is full of supplemental videos, showing how illusions work as mechanical effects, scientific principles and bravura performances. The performers who assisted the authors -- James Randi, Penn and Teller, Derren Brown, and, of course, Apollo Robbins -- are all justly famed for their skill, and the book is worth a read just for the insight it provides into their work. But it goes so much farther, providing both a theoretical underpinning in the neuroscience of perception and consciousness, and practical advice on how to apply this to your everyday life.

One interesting note: the authors mention a book called The Official CIA Manual of Trickery and Deception, which reprints the secret (and long-lost) training documents that magician John Mulholland created for the Agency in 1952, which were used at the height of the Cold War by US spies to deceive their Soviet counterparts -- for example, details of how to use the "big move" of lighting a cigarette to disguise the "small move" of slipping drugs into a rival's drink. I haven't read this yet, but I've just ordered it.

  2. In my opinion, describing a book as well-balanced requires that the authors acknowledge dissenting opinions to the theories they advance. Having read Sleights of Mind, I recall no reference to anyone refuting their findings. I provided comments in a related Boing Boing post yesterday from several individuals who challenge their claims. It’s disappointing that these questions would not be addressed in today’s post.

  3. Sleights of Mind has been widely discredited in the magic community by those who actually know something about the performance of magic. It’s mostly hogwash. You can read the criticisms both in Genii, The Conjurors’ Magazine and on, where real magicians know whereof they speak.
    And the John Mullholland involvement with the CIA was fully documented, and his manual printed, in Genii, The Conjurors’ Magazine, many years before the two authors of that book got their hands on it.
    The public is easily duped.

    1. Mr Kaufman above is quite wrong. I know something about the performance of magic and I have not discredited this book. The only “hogwash” is that perpetrated by Richard Kaufman who as a magician could not make the contents of an empty box disappear. He cannot speak for the magic community as he has been banned from attending the biggest magic convention in the world and quite rightly so.  It is true that real magigicans know of what they speak but alas those real magicians are not to be found in the pages of the sources to which he refers. They are all amateur magicians with no professional experience. Come to think of it so is Mr Kaufman. I am afraid their opinions are of no value whatsoever.
