Mimi Levin Lieber (March 22, 1928 – October 16, 2021), born Miriam Leah Levin, was a sociologist who developed new techniques in consumer attitude research. As a member of the New York State Board of Regents, she became a significant figure in shaping elementary education policy in New York. Much of her early professional career focused on targeted forms of behavioral economic research. Analysis and interview methods developed by Lieber and her contemporaries helped lay the groundwork for modern integrated marketing tools, such as focus groups and opinion polling. Later in life, Lieber turned her efforts toward children's literacy advocacy, most notably in her founding of Literacy Inc.
