I agree that one's IQ or mile time does not solely reflect their intelligence or athleticism respectively. But, I believe they are certainly worthy measurements and are very big contributors to the whole picture. If someone tests with an IQ of 70 and runs a mile in 9 minutes, those are very indicative of that person's lack of intelligence and athletic ability. To dismiss these quantitative measures would be leaping in the direction (where I think you are going) in that everyone is the same (just in different ways). This is just not true in my opinion. People are more intelligent than other people and people are more athletic than other people. Also, these tests are not permanent measures. One can work at their intelligence or running and achieve better results the next time they compete, therefore these tests can also measure how much one has bettered themselves in whichever field they are working. They can be used as a self-measurement to gauge one's progress.
