Because the results are ...

Because the results are expressed in numbers, it is easy to make the mistake of thinking that the intelligence test is a measure like a foot ruler or a pair of scales. It is, of course, a quite different sort of measure. Intelligence is not an abstraction like length and weight; it is an exceedingly complicated notion - which nobody has yet succeeded in defining.

What the public does is not to express its opinions but to align itself for or against a proposal. If that theory is accepted, we must abandon the notion that democratic government can be the direct expression of the will of the people. We must abandon the notion that the people govern. Instead, we must adopt the theory that, by their occasional mobilizations as a majority, people support or oppose the individuals who actually govern. We must say that the popular will does not direct continuously but that it intervenes occasionally.
