You've probably never given much thought to the fact that
picking up your cup of morning coffee presents your brain with a set of complex
decisions. You need to decide how to aim your hand, grasp the handle and raise
the cup to your mouth, all without spilling the contents on your lap.
A new Northwestern University study shows that, not only
does your brain handle such complex decisions for you, it also hides
information from you about how those decisions are made.
