The why does it correspond so nearly perfectly with every factor of lifetime beh

The why does it correspond so nearly perfectly with every factor of lifetime behavior? Why does it correspond with every factor of national differences? Why is it the most predictive measure we have? I think you’re likely one of the people who conflates intelligence (rate of learning, rate of error correction, rate of adaptation) with learned skill and/or personality differences (particularly conscientiousness). How do you know you’re not making that error?
