Ironically, this guy has successfully convinced me that IQ tests are absolute psuedoscience and are nothing more that completely misued personality tests. Previous to this podcast I thought it was real science, but this expert has provided nothing more than correlations with thousands of factors.,(reply>), There are volumes more research data on IQ than any other area in psychometrics. Get real,(reply>), @Bill Carson His approach is not scientific as IQ research (like diet research - and we know how conflciting that is often is) has far too many outside variables that cannot be controlled for. For example, it is possible that in finding correlation between IQ and life expectancy, you are actually mapping a correlation between general test taking ability and life expectancy. Or one of thousands of other factors that someone could evaluate. IQ, unlike gravity or mass, is not a scienfiticly measurable variable, and its existence cannot be proven. The test seems to offer some perspective on outcomes for people, but it is not fair to call that "intelligence" at all.,(reply>), Ironic or not, you have convinced me of even less.
