Can the right words convince someone to donate their blood? An initiative in New York has turned to machine learning to figure out who is most likely to give blood - and how to encourage them to do so more frequently. The project is aimed at improving the turnout of African Americans, who are disproportionately less likely to donate or become regular donors. Though race is not relevant for standard blood transfusions, type B blood is more common in African American people. Also, ethnicity may help provide a match for blood transfusions to people with sickle cell disease, a condition that is seen more often in African Americans.
