With regard to the goals of the validation process, advocates of the composite criterion
assume that the validation process is carried out only for practical and economic reasons, and not
to promote greater understanding of the psychological and behavioral processes involved in
various jobs. Thus, Brogden and Thylor (1950a) clearly distinguished the end products of a given
job (ob products) from the job processes that lead to these.end products. With regard to job
processes, they argued: "Such factors as skill are latent; their effect is realized in the end product.
They do not satisfy the logical requirement of an adequate criterion" (p. 141).
