Series 1: Correspondence, 1947 -- 1974

This series is open for research.

6 folders

This series contains correspondence about the studies as well as information about the donation of the collection to the Missionary Research Library. Thayer was a firm believer that the Missionary Research Library was important, and had used the resources for his own PhD thesis published in 1951. Thayer offered copies and details on the studied missionaries and their results to the Boards of Missionary Organizations and this series also contains that correspondence.

This series is arranged roughly chronologically.

Series 3: Studies, 1952 -- 1974

This series is open for research.

5 boxes

This series contains records from various studies that became Thayer's life work. Inspired by the original testing done in the 1930s, Thayer held his own major study to be included with his PhD thesis in 1951. When this study proved inconclusive, Thayer continued the testing again. After his thesis, the three major studies conducted were held in 1966, 1969 and 1972. Thousands of missionaries from a variety of boards and backgrounds were studied over the course of these tests. The tests were completed using computers at the University of Florida (1966); the University of West Virginia (1969); and Cleveland State University (1972). The collection offers the results and data tables from these three studies, as well as the complete set of computer cards from the 1972 study.

This series is arranged roughly chronologically.
