I took a free IQ test on the computer and it was easy, I breezed right thru it, multiple little drawings of squares with lines going thru etc, actually related to my occupation, comparing things, but when they wanted $29.95 to see my score and get a document, I stopped.
I’m thinking if the hi IQ came from birth genes or schooling, then no common sense. If working first, making building creating things and doing things, that I think that gleans both at the same time maybe. Pretty much any high skilled tradesmen have common sense or they would fail.
