Having or showing a blank mind; lacking thoughts, focus, or mental engagement; absent-minded.
From blank + minded (from mind). Minded comes from Old English gemynd, and compounds with 'blank' to describe a mental state that is empty or unoccupied.
Neuroscience has discovered that a 'blank-minded' state is when your default mode network is highly active—essentially your brain is daydreaming and processing emotions rather than thinking about the world, which is why you can drive home on autopilot with zero memory of the journey.
