Born in
Merrick, New York, Jackson graduated from
Cornell University in 1951 with a
B.S. in
industrial and labor relations and earned his
Ph.D. from
Purdue University in 1955 in clinical psychology. Jackson taught at
Pennsylvania State University (1956–62) and
Stanford University (1962–64) before starting at
University of Western Ontario in 1964, where he taught for over 32 years. Jackson created numerous tests in his life, including: •
Multidimensional Aptitude Battery (MAB) • Personality Research Form (PRF) •
Jackson Vocational Interest Survey (JVIS) • Employee Screening Questionnaire (ESQ) These were distributed through two companies he founded, Research Psychologists Press and Sigma Assessment Systems. He collaborated with
Samuel Messick at the
Educational Testing Service, examining
construct validity. Jackson also published several analyses on
sex and intelligence that found males applying to medical schools had a small but nontrivial advantage in
general intelligence factor and in reasoning. Jackson served on the Executive Council of the
International Test Commission and was a Fellow of the
Royal Society of Canada (1989). He was president of the Society of Multivariate Experimental Research from 1975–1976 and received their Saul Sells Award for Lifetime Contributions in 1997. He was President of
APA's Division of Measurement, Evaluation, and Statistics from 1989–1990 and was awarded that division's Samuel J. Messick Award for Distinguished Scientific Contributions in 2004. In 1994 he was one of 52 signatories on "
Mainstream Science on Intelligence," an editorial written by
Linda Gottfredson and published in
The Wall Street Journal, which declared the consensus of the signing scholars on issues related to the controversy about intelligence research that followed the publication of the book
The Bell Curve. Colleague
J. Philippe Rushton noted that Jackson's founding of Canada's
Society for Academic Freedom and Scholarship was a response to "Canadian researchers challenged by '
political correctness'" and "demonstrated his personal commitment to ensuring personal liberty and freedom of enquiry for his colleagues." ==References==
