Pick a Destiny, Any Destiny

David Blaine’s street magic specials are always fun to watch. If you haven’t seen what he does, this is a great example.

Now, if you’re anything like me, your immediate reaction was, “Oh my God – how did he do that?!” It almost felt like he was reading that woman’s mind, since it looked like she had the choice to have “picked a card, any card.” But in fact, where magicians like David Blaine are truly masters of illusion is in creating the best illusion of all – the illusion that we have free choice.

One of the reasons magicians are able to “know” what card we’ve picked is because they have already determined what card they wanted us to pick – it was never really actually “our” choice in the first place. Their trickery lies in their ability to lead us to feel invested in “our” decision.

Stephen Macknik and Susanna Martinez-Conde are the authors of the book Sleights of Mind: What the Neuroscience of Magic Reveals About our Everyday Deceptions, and they argue that the reason we feel like we were the ones who actually picked the card was because “[o]ur minds will go to surprising lengths to preserve [our] sense of agency and choice.” (pp. 171-172) In other words, our brains sometimes lie to us, leading us to believe that we have much more control over our situations than we actually do.

And yet that’s actually not all that surprising. We know in our own lives that we do not have unlimited choice – there are very real limits to what we have the freedom to do. We can not simply “choose” to get a million dollars – we have to work hard at a high-paying job, and even then, luck will play a big role in whether or not we succeed. We cannot just “decide” to lose weight – we have to diet and exercise, and even then, our metabolism or our willpower may make it challenging to meet that goal. Our genetics, our environment and our past decisions all restrict our choices to an extent. While we may want to believe we have total and complete free will, when we reflect on it, we recognize that we are not nearly as free as we think.
