The Quality of Research is Strained

Abstract
In an effort to learn more about the cumulative nature of psychological gerontology, as well as the reliability and validity of data in this area, an analysis was undertaken of professionally published articles dealing with psychological and related processes and listed in Shock's Current Publications in Gerontology and Geriatrics, published in 1968 in the Journal of Gerontology. Findings indicated a remarkable amount of noncomparable data. Operational definitions of young and old varied widely; sampling frames were dissimilar. In general, there appeared to be little evidence to encourage the viewpoint that science is cumulative, at least insofar as psychological aspects of gerontology are concerned.
