I was listening to CBC Radio the other day while I was driving.
I can't remember what the program was about, due to my failing retention, but the discussion focused on thinking for ourselves. On challenging those who make authoritative statements founded on nothing but opinion; where hubris gets in the way of truth.
It's coming back to me now. Steve Sloman was discussing his book, “The Knowledge Illusion,” that focuses on the sense of some people (most people, in his estimation) who are convinced they know just about everything there is to know about everything.
