The Importance of Interest in IQ

I really believe that this set of theories starting with universality and even including breadth theory of that we're measuring the wrong things with IQ, right? It could take the concept of IQ. I mean, imagine if we took breadth theory seriously and we said, maybe we can explain a great deal of IQ differences just based on differences in what people value. How would you go about testing that? What are the testable consequences of trying to look at it in that way? There are going to be some. This isn't a metaphysical theory. It's a scientific theory. And you gotta treat it like that.
