ABSTRACT
There is an old joke to the effect that the one result of any piece of research is a call for further research on the same topic. Surely, a great deal of research does end with such a plea, and very properly so—the researcher would be negligent if he or she did not communicate what had been learned about what he or she had not known. Good research pushes back the frontier of ignorance and spreads the territory of knowledge, but progress is measured in millimeters along a road which is kilometers long. The research reveals “truth” as defined and measured in some way, but it also reveals ignorance, some of which was unexpected when the research began. As the researcher pushes out across the plains and mountains, one ridge or mountain is climbed, only to reveal more ahead. It would be highly irresponsible of any researcher not to point out what he or she now thinks still remains to be learned, as well as to relate accurately what had been learned by the research.
