IQ is only one measure of intelligence, or to put it another way, only measures one facet of the complex reality that we call ‘intelligence.’ It’s like trying to characterize people physically solely by their height.
What a person can do beats some score on an artificial test.
Excellent comments in those first posts there!
I.Q. is a measurement of how well someone does on I.Q. tests. Only some mental abilities and skills can be measured by a test. There must be more to the picture. Maybe a series of real-life simulations would give a more accurate picture.
