In his first book, On Being Certain: Believing You Are Right Even When You’re Wrong, neurologist Robert Burton showed that our certainty that we are right has nothing to do with how right we are. He explained how brain mechanisms can make us feel even more confident about false beliefs than about true ones. Now, in a new book, A Skeptic’s Guide to the Mind: What Neuroscience Can and Cannot Tell Us About Ourselves, he investigates the larger question of how a brain creates a mind. There is no alternative to the scientific method for studying the physical world, but Burton thinks there are essential limitations to science’s ability to investigate conundrums like consciousness and free will. Brain scientists fall into error because:
…our brains possess involuntary mechanisms that make unbiased thought impossible yet create the illusion that we are rational creatures capable of fully understanding the mind created by these same mechanisms.
He has a bone to pick with neuroscientists. They are discovering fascinating information, but their interpretations often go beyond what the data can really tell us. They often draw questionable conclusions from imaging studies that could have other explanations. (more…)
