A
person who could be very well-informed and
high-functioning, possibly even quite intelligent in certain areas, but is an idiot nevertheless. Usually a smooth-brained
person has never thoroughly examined their beliefs, is generally susceptible to ideology, and has enjoyed a relatively comfortable life
free of struggle or adversity.
Smooth-brained can also describe an article, film, or any other piece of content that presents a view of the world that betrays the author'
s complete alienation from any of the material conditions that define most peoples' lives.
Can also be used as a noun, for example: smooth-brain.
