ABSTRACT
One of the most appealing ideas of our century is the notion that science can be put to work to provide solutions to social problems. The numbers of social practitioners listed in the census, social, group, recreation, and welfare workers and persons employed in personnel and labor relations, have increased at a faster rate than the rest of the labor force, but the actual practice in welfare and personnel does not seem to have changed appreciably. Social problems cry for solutions and cannot normally wait for science to develop the appropriate laws or furnish the relevant information. Even when research funds are available, the scientific proofs demand long investments of time, and the time is often scarce when the cry "Do something!" is in the air. Thus, practitioners and consultants are frequently called into action to give scientific solutions when such solutions hardly exist.
