"Many of the most critical problems in the social sciences involve a religious factor. A purely rational economic model of man, for example, whether it involves the market as a system or individual economic behaviour, must take account of the "distortions" produced by religious motivations and values. Prediction and explanation of political behaviour are improved if, in addition to knowledge of class, education, occupation, traditional political identity, and the like, there is a knowledge of religious group membership, belief, and behaviour." -- Encyclopaedia Britannica 1987
