The Implicit Association Test at Harvard helps to provide more self-understanding of users' own biases, attitudes and beliefs. The IAT measures the strength of associations between concepts and evaluations or stereotypes, asking users to quickly sort words into categories.
The resulting score is based on how long it takes a person on average to sort out words in different parts of the test, depending on the speed of association of words with different categories.
Project Implicit is a non-profit organization and international collaboration between researchers who are interested in implicit social cognition - thoughts and feelings outside of conscious awareness and control. The goal of the organization is to educate the public about hidden biases and to provide a “virtual laboratory” for collecting data on the Internet.
