Are we all racist? Harvard professor Mahzarin Banaji is the architect of what is arguably psychology’s most influential experiment. It’s called the Implicit Association Test (the IAT) and it has been taken millions and millions of times. It purports to be a measure of our unconscious bias towards various groups – e.g. blacks, women, the old or the disabled. Most people taking the IAT do exhibit some kind of bias. That leads to two questions – how worried should we be at these implicit attitudes, and what could be done about them?
