Derren Brown is clearly on to something. And if you’ve read his books you’ll know that what he’s on to is finding ways to tap in to our fascination with how our thoughts and actions can be manipulated using some well-defined and researched techniques and principles. Add in some showmanship and what you have is something that is indistinguishable from magic. You can believe in the magical and mystical if you like, but Derren Brown is a creature of the Enlightenment and has no truck with any of that. He’s got psychology and science on his side. The magic is in our own heads. It’s not just Derren Brown who has used the findings of psychologists to find ways to control people. Many of our current beliefs and the very workings of our society are based on this sort of manipulation. You can also see its workings in the way we think we think we can use workplace design to influence the feelings and behaviour of others.
