The complexity and the technical obscurity of the scientific method have rendered science ever likely to be misunderstood both by scientists themselves and by the general public. Difficulties which remain unrecognized constitute the most formidable obstacles to success in any field. There are such difficulties lurking in the treatment which the scientific method accords its subject-matter. In this essay, I propose to point to one such pitfall in the path of the progress of science. By exposing it, something will already be accomplished toward its avoidance and elimination, and the vast public of uninstructed persons will be able to skirt one more confusion in the effort to understand what the scientists are trying to do.
