How People Differ from One Another Psychologically: IQ and the Big 5—Jordan Peterson

This particular class is a great introduction to IQ and to personality theory in psychology. Also, Jordan Peterson does a great job of skewering the twisting of psychology to tell people what they want to hear. In particular, (a) IQ is a very well-defined measure (with such strong correlations between different problem-solving skills that it looks to be dominated by one factor), (b) IQ does a great job of predicting important things and (c) very few psychological trait concepts add anything beyond IQ and the Big 5 personality traits or IQ and the Big 10 that come from splitting each of the Big 5 into 2 (although showing how things with other names relate to IQ and the Big 5 or Big 10 can be quite illuminating).

Highly recommended for economists who want to quickly learn key concepts from an area of psychology quite relevant to economics, but different from the social psychology that is most similar to experimental economics.

One conjecture: I suspect that measures of economic preference parameters do tend to be distinct from IQ and the Big 5. But if not, the way preference parameters could be predicted by IQ and the Big 5 would be quite interesting.
