Telepathy was once nothing more than a parlour trick played by illusionists to entertain us. Names would seemingly be pulled out of our heads, numbers would be correctly guessed, our hiding places revealed. It was all done through trickery – reading our body language, tone of voice, and movement of eyes. Magic doesn’t really exist, and neither did mind-reading. At least that used to be true, until the mind-reading wizards arrived. Now something resembling telepathy is becoming a reliable reality. Being poker-faced will not help you any more. Even if you control every movement of your muscles or flicker of your eyes, you will never hide your brain activity. The magic word is not abracadabra, but Hex-o-Spell!
