I've heard that saying also that a genius has no common sense.
I had a funny experience of my own in a gym with a woman I worked out with.
I had brought one of those big exercise balls in to have air put into it and she was talking about
the breakdown of a price she had paid for script sunglasses. Test, lenses, tints, frames, etc.
Her question was what did she pay per lense for two pairs. She was read off all the prices
that added up to the total and as she was reaching for her calculator I gave her the answer in
a split second.
You must be one of those math genius people! She said.
I replied, no, I don't like math actually.
Then she went on to talk about how she thought my actions and things I spoke about were "different".
So she concluded I must be a genius.
I told her my IQ tests always had been in that range, yes.
As I walked out the door with the big exercise ball, she offered to carry it to the car for me.
I got my keys and started looking all around the lot.
Uh, I had forgotten where I was parked.
She laughed and said that's a genius for you.
Intelligence with no common sense!
Funny or not, I guess there is something about the common sense factor?
But, if the test is to score intellectual ability, it would have to be carefully constructed
to measure that and that alone.
Not knowing something you've never been exposed to in life would not be an accurate test.
You could be a hermit monk and have very good reasoning skills and intellect,
yet having lived in isolation you might not know what the periodic table is.
You might answer, " a table that is used only occasionally?"
I love a line from one of the Kung Fu series where a woman says to him:
"You know so little, yet so much."
