It's a question that has plagued philosophers and scientists for thousands of years: Is free will an illusion?
Now, a new study suggests that
free will may arise from a hidden signal buried in the "background noise" of chaotic electrical activity in the brain, and that this activity occurs almost a second before people consciously decide to do something.
Though "purposeful intentions, desires and goals drive our decisions in a linear cause-and-effect kind of way, our finding shows that our decisions are also influenced by neural noise within any given moment," study co-author Jesse Bengson, a neuroscientist at the University of California, Davis, wrote in an email to Live Science.
"This random firing, or noise, may even be the carrier upon which our consciousness rides, in the same way that radio static is used to carry a radio station."
This background noise may allow people to respond creatively to novel situations, and it may even give human behavior the "flavor of free will," Bengson said.
Comment: What's missing from this list is a description of the normalcy bias which, if left unchecked and unrecognized, could have devastating effects for many in the chaotic times ahead.
