Definition of an Expert

I cannot recall whether I have shared this before, but my father had a saying that always tickled me. He said:

An expert is someone who can tell you today exactly why what he said yesterday did not happen.

The weather forecasters cause me to think of this saying almost daily. Other “experts” likewise make me think of this.

In addition to my father’s saying, I have some other thoughts.

An expert is someone who is able to convince others to elevate him and his opinions above their own, and usually even to praise and pay him for sharing his elevated opinions.

For what it is worth.
