Dr. Jordan B Peterson, a Professor of Psychology at the University of Toronto, a clinical psychologist claims (reference: https://www.youtube.com/watch?v=h02w5E7FGlY) that "the IQ claims are more psycho-metrically rigorous than any other phenomenon that's been discovered by social scientists".
However, a quick googling would return many articles indicating that IQ tests do not accurately measure intelligence. It seems to me that these are radically opposing claims and I would like to ask if there is scientific agreement either way.
