Zack Zdenek Cernovsky (January 26, 1947 – October 25, 2021)[1] was a Canadian psychologist. He was a professor of psychiatry in theSchulich School of Medicine & Dentistry[2] at theUniversity of Western Ontario. He was educated at theUniversity of Berne and theUniversity of Zurich, and taught overseas classes for theUniversity of Maryland before joining the faculty of the University of Western Ontario. His more than 180 scientific publications in psychology and psychiatry deal with topics such as theMMPI,schizophrenia, psychological statistics and research design,sleep disorders,PTSD symptoms in refugees, the frequent psychological polytraumatic symptom pattern encountered in survivors of motor vehicle accidents (chronic pain, pain related insomnia,post-concussion andwhiplash syndrome, PTSD, depression, generalized anxiety anddriving anxiety), and assessments of subjective psychological symptoms of whiplash injury, as a part ofmedical psychology.
He published[3] statistical/methodological critiques of the work of racial theoreticianJ. Philippe Rushton[4][5][6][7][8] and more recently also ofRichard Lynn.[9]
His work also focused on demonstrating the lack of content and criterion validity of theStructured Inventory of Malingered Symptomatology (SIMS), a widely used test that excessively frequently misclassifies legitimate medical patients asmalingerers, especially those patients who experience the psychological polytraumatic symptom pattern (e.g., survivors of motor vehicle collisions, injured war veterans, civilians injured in industrial accidents), thus falsely depriving injured persons of medical attention, therapies, and of legally owed insurance benefits.[10]
