Sandra Wood Scarr (August 8, 1936 – October 8, 2021)[1][2] was an American psychologist and writer. She was the first female full professor in psychology in the history of Yale University. She established core resources for the study of development, including the Minnesota Transracial Adoption Study and the Minnesota Adolescent Adoption Study. She served as president of multiple societies including the Association for Psychological Science and was honored with multiple awards including the James McKeen Cattell Fellow Award. She was also active in the development of commercial childcare. Her work with twins in the 1960s revealed strong genetic influences on intellectual development. One of her key findings was that this differed with race and socioeconomic status (SES), with poor and non-white children showing less genetic influence on their IQ and more environmental influence.[citation needed] She demonstrated a successful intervention in premature infants, showing that stimulation improved their health and developmental outcomes.[citation needed]
At Minnesota, she and Richard A. Weinberg found that black and interracial children adopted early into white homes initially had outcomes more similar to the white average, suggesting a role of family environment early in life. By their teens, adoptees with two black birth parents achieved lower scores than did adoptees with one or no black birth parents, suggesting a genetic component to race differences in IQ.[3][4][5][6]
Along with the Scarr-Rowe effect of socio-economic status on the heritability of intelligence, another key intellectual landmark established by Scarr was that "Rather than the home environment having a cumulative impact across development, its influence wanes from early childhood to adolescence."[7] She sought also to advance scientific psychology, and in 1991 co-founded Current Directions In Psychological Science.[7] She retired to Hawaii.
In the 1960s, Scarr studied identical and fraternal twins' aptitude and school achievement scores. The study revealed that intellectual development was heavily influenced by genetic ability, especially among more advantaged children. It also showed that on average, black children demonstrated less genetic and more environmental influence on their intelligence than white children. Scarr also collaborated with Margaret Williams on a clinical study which demonstrated that premature birth infants who receive stimulation gain weight faster and recover faster than babies left in isolation (the practice at that time).
In 1972 she married fellow researcher Philip Salapatek, with whom she also coauthored papers. They had a daughter, Stephanie (November 1973).[7] They moved to Minnesota, where Scarr started working with Richard A. Weinberg, on the Minnesota Transracial Adoption Study. This study concluded that black and interracial children adopted early into white homes had IQ and school achievement scores that averaged similar to those of white children.
In another adoption study, Minnesota Adolescent Adoption Study, Scarr and Weinberg showed that adolescents, adopted in the first few months of life, did not resemble their adoptive parents or other children adopted into the same family. In Scarr's words: "Rather than the home environment having a cumulative impact across development, its influence wanes from early childhood to adolescence." (emphasis in original).[7] As of 1995, the study was among the largest of its kind in the United States, together with the Colorado Adoption Project and the Texas Adoption Project;[9] its results had seen some replication.[10]
In 1990, Scarr was invited to join the Board of the KinderCare Learning Centers, the nation's largest child care company. In 1993, she was elected chairman of the board and in 1995 became CEO and chairman of KinderCare. While at KinderCare, Scarr instituted NAEYC accreditation for the centers and worked to improve the wages and working conditions of center staffs. In 1997, KinderCare was bought by Kohlberg, Kravitz, and Roberts Investments, and Scarr retired
In 1991, together with Claire Ernhart, Scarr was involved as an expert witness on behalf of the lead industry in the lawsuit United States v. Sharon Steel Corp., on the opposite side of Herbert Needleman who was testifying for the U.S. Justice Department owing to his research on the relationship between lead exposure and IQ. The federal court asked Scarr and Ernhart to examine the research of Herbert Needleman to determine whether or not it supported his claims. After reviewing his data collection and analyses, Scarr and Ernhart filed charges of scientific misconduct against Needleman with the National Institutes of Health. NIH forwarded the complaint to the University of Pittsburgh, which found that Needleman did not "fabricate, falsify or plagiarize",[14] but a Preliminary Inquiry Panel said it could not exclude the possibility that "misrepresentation" had occurred.[15] When the trial was declared open to the public, Scarr initially refused to come and later when she was persuaded she constantly refused to answer questions.[16] Scarr received money from the lead industry for consulting services which creates a conflict of interest.[17]
Retirement
Scarr retired to Hawaii in 1997, where she learned scuba diving, even obtaining a rescue diver certification. She also traveled "a lot, especially on cruise ships".[7]
Death
Scarr died on October 8, 2021, in Holualoa, Hawaii.[2]
