Barbara Stoddard Burks was an American psychologist known for her research on the nature-nurture debate as it pertained to intelligence and other human traits. She has been credited with "...pioneer the statistical techniques which continue to ground the trenchant nature/nurture debates about intelligence in American psychology."
Early life and education
Burks was born on December 22, 1902 in New York City, New York, to Jesse and Frances Burks. When she was a child, her family moved to many different locations before eventually settling in California. There, she started her undergraduate studies at the University of California, Berkeley, where she worked with Edward C. Tolman. Under Tolman's supervision, she became skilled at conducting statistical analyses based on his research on rat breeding. In her senior year, she transferred to Stanford University, where she began studying under Lewis Terman. She received her bachelor's degree from Stanford in 1924. Terman was so impressed with her performance as an undergraduate that he recommended that she immediately enroll in graduate school. She then did exactly that, enrolling in Stanford's Ph.D. program in psychology, where she worked with Terman on his "Genetic Studies of Genius" project.
Burks is particularly known for her 1928 Ph.D. dissertation, which examined the relative effects of genetics and environment on the IQ scores of foster children in California. This dissertation, completed at Stanford University, has been described as "a pioneering study in the field of behavioural genetics". Her dissertation concluded that between 75 and 80% of variation in IQ scores was due to genetic factors. The data would be used by Sewall Wright for path analysis of heritability issues. The study was cited favorably by Arthur Jensen in support of his hereditarian views, but it has been criticized for having a biased sample and for its limited measurements of environmental factors. While working as a graduate student at Berkeley, she was one of Terman's research assistants on his "Genetic Studies of Genius" project from 1924 to 1929, and served as the lead author of its third volume, , which was published in 1930. These studies followed up a group of children who had been identified as being highly intelligent early in life, and found that they were still exceptionally intelligent many years later. At the time of her death, she had recently received a Guggenheim Fellowship to study identical twins adopted apart.
Personal life
Burks married Herman Ramsperger, a National Research Fellow in chemistry at Stanford, in 1927; they remained married until his death in 1932. In 1943, she became engaged to longtime friend Robert Cook, but she died before they could be married.
Death
Burks, then a research associate at Columbia University, died on May 25, 1943, when she "either fell or jumped to her death from the George Washington Bridge" in New York City, New York. King et al. cite letters in the Terman archive to the effect that "She had also become engaged to marry Robert Cook but, according to her mother, had continually struggled with depression following a “severe nervous breakdown” in 1942."
