Guest: Catherine Bliss, PhD, Associate Professor in the Department of Social and Behavioral Sciences, University of California, San Francisco, Author of “Social by Nature: The Promise and Peril of Sociogenomics” As DNA testing becomes more common, researchers are on a quest for “genius genes” that will answer once and for all just how much of a person’s intelligence is inherited and how much is due to environmental factors like schooling or home life. But is that knowledge we need? Could a genetic test for IQ backfire, ethically or morally?
