Jessica Ravitz's new book, "Bias," explores the history of prejudice in the U.S. The psychology field tends to group bias into two categories: intentional and unconscious. Ravitz says we are an unknowable combination of conscious and unconscious biases. We can be made aware of it if we just pause to notice it, she says.
Jessica Nordell—science and cultural journalist—explores ways of changing pernicious thought patterns to eliminate unconscious bias for a more just world.
