Brain scans can reveal your decisions before you actually decide
Here’s an interesting experiment about making decisions, though it involves fairly simple decisions, with only two alternatives.
An interesting experiment, though I doubt that it has much to say about “free will”. What it shows is that the brain is analogous to a computer — well, it is a kind of computer, wetware, as some call it — and like any computer, when it does calculations it takes some time before the results are displayed on the screen.
What it could suggest, though, is that the mind, or consciousness, is not completely identical with the brain, and that the mind “uses” the brain in a way analogous to the way we use computers. These analogies can sometimes be fun to play with. In Christian theology we sometimes speak of the resurrection of the dead — that one day when an angel blows the big vuvuzela (see here, for an artistic representation) we will all rise from the dead and get new bodies. One could use a computer metaphor for this, and say that God has us all backed up on tape or DVD or something, somewhere, and one day we will be rebooted with new and improved hardware.
