Biography

Joseph received his undergraduate education from the University of California, Berkeley. He went on to receive his master's degree from the New College of California in 1994 and his Psy.D from the California School of Professional Psychology in 2000. He received his license to practice psychology in California in 2003. In 2014 he published The Trouble with Twin Studies, which argued that research based on twin studies was highly flawed and could not be used to prove heritability of traits, as they fail to adequately control for environmental factors, as well as accusations of ethics violations in research practices.Joseph, Jay. The trouble with twin studies: A reassessment of twin research in the social and behavioural sciences. Routledge, 2014. The book was negatively reviewed by one psychologist, Eric Turkheimer, who argued that twin study research was valid.Turkheimer, Eric. "Arsonists at the Cathedral." PsycCRITIQUES 60, no. 40.
