[ 1][ 2] In other words, a test can be said to have face validity if it "looks like" it is going to measure what it is supposed to measure. [ 3]

For example, an invalid inference "Because everybody ought to be equal, there are no innate genetic differences between people" is an instance of the moralistic fallacy.
