I am trying to engineer something that is more rational than humans are. Stanovich, et al attempt to define rationality and distinguish it from intelligence in their new book The Rationality Quotient (MIT Press, 2016). I am interested in doing the same thing but I believe that rationality and intelligence need to be described by vectors rather than scalar values.
It's true that attempts to measure intelligence (as IQ) fail to include some of the factors that Stanovich, et al list. But another part of the distinction between rationality and intelligence comes about due to the attempt to measure each as a scalar quantity. It seems to me to be possible to think in terms of a single VECTOR "rationality/intelligence."
