General Intelligence Determined by its Weakest Essential Element

Abstract

A chart is presented giving a diagrammatic representation of general intelligence and some arbitrarily selected special abilities. The x -ordinate or base of the diagram represents the extent of the qualitative variety or the multiplicity of abilities of the total capacity of an individual. The height of the diagram of any particular part represents the quantitative aspect or the amount of any particular ability. A few particular abilities are represented by curves similar to the frequency curves. General intelligence might be represented by a line touching the tips of the particular abilities entering into general intelligence as it is usually considered. The measure of general intelligence might more consistently be represented by the elevation of a straight line drawn as to just touch the top of the curve of the weakest necessary ability. General Intelligence is similar to a chain which is no stronger than its weakest link. Fourteen references are appended. From Psych Bulletin 18:01:00096.
