Born in Merrick, New York, Jackson graduated from Cornell University in 1951 with a Bachelor of Science in Industrial and Labor Relations and from Purdue University in 1955 with a Doctor of Philosophy in Clinical Psychology.
Jackson taught at Pennsylvania State University (1956-1962) and Stanford University (1962-1964) 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 (Economic Studies Quarterly)
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). 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.
