Using sophisticated brain imaging techniques, the researchers found that they can predict people's simple decisions up to 10 seconds before they're conscious of making such a choice.
"It seems that your brain starts to trigger your decision before you make up your mind," said the study's lead author, John-Dylan Haynes of the Max Planck Institute for Human Cognitive and Brain Sciences in Germany. "We can't rule out free will, but I think it's very implausible. The question is, can we still decide against the decision our brain has made?"

"It's not like you're a machine. Your brain activity is the physiological substance in which your personality and wishes and desires operate," he said.
The unease people feel at the potential unreality of free will, said National Institutes of Health neuroscientist Mark Hallett, originates in a misconception of self as separate from the brain.
"That's the same notion as the mind being separate from the body -- and I don't think anyone really believes that," said Hallett. "A different way of thinking about it is that your consciousness is only aware of some of the things your brain is doing.
