My catholic HS placed us in classes at four levels. The first level had the highest IQ and so on. I was 127 and was in the highest group. There was one guy in our groups who must have been off the chart. BTW never had my IQ tested again.
I was the youngest in class and didn’t know that till a reunion. I refer felt less smart than anyone except the one guy.
I value experience. As I went along in my 28 year career, i found at any level (I had 23 jobs progressively analytical and management not hands on, but needed people skills) I was soon better than my bosses. But i also had extra training. I did consulting work in 15 states and one day into their systems nd work sites I could deliver training with relevant examples etc.
I think success is a result of a lot of variables including IQ, but common sense and experience would be a little higher on my list because they lead to intuition which can be more on target than not.
My 25 cents worth
I NEVER felt less smart
I agree that IQ plus intelligence is important. But ,I also agree with your observation that experience is important. I agree because it focuses your common sense. It is very important and is why most politicians make such stupid decisions, most have no real-world experience.
