What do you exactly measure by comparing IQs? A person who does not do well on math test can become much more "successful" than a person who does. How does IQ really correlate with success?
They should both be important is his point. And measurements for IQ (and EQ frankly) aren't very reliable. His point seems to be that "smart" is not really measurable as we don't include EQ and our measurements of IQ are poor as well.
