The editor of this Journal has asked me to comment on the preceding paper by Professor Hammond (5) in which certain parallels are drawn between relativity physics and my own suggestions concerning the establishment of “representative design” in psychological experimentation (1). Since I find little basis for criticism of Dr. Hammond's major line of reasoning, I shall concentrate on anticipating possible objections to Hammond's comparison as well as on elucidating my point of view by means of examples, both old and new, that seem pertinent in the present context.
