Project Implicit

This link takes you to Harvard's Project Implicit, where you can take online tests to become aware of implicit biases. 

Background (For the curious: need not be read to participate in the test)
Harvard’s Project Implicit uses an online test that helps individuals gain a greater awareness of their own unconscious preferences and beliefs. We often do not express our preferences and beliefs, either because we consider them private or because we are unaware of our own attitudes. Implicit bias undoubtedly operates in academia, and contributes to the general climate. Indeed, the careers of women and minorities may be impeded by barriers, not because men and whites are evil, but because all of us, women and men regardless of race, acquire unconscious cultural biases and attitudes that, when not reigned in by conscious control, form a basis for our behavior.

The Harvard online research test measures how strongly you associate paired concepts. You are asked you to pair concepts. In their FAQ, they use the example young and good, or elderly and good. The more closely you associate the two concepts, the easier it will be for you to respond to them when they are presented or your screen and you are asked to give the same response on a keyboard (i.e. the 'D' or 'K' key) to these two. If you do not unconsciously associate elderly and good strongly, then it should be harder to respond quickly when they are paired.

You can select tests from an number of areas. As a guide, in each test you generally first fill out a brief questionnaire asking your sex, age, race, ethnicity, education and specific information such as, for the 2008 Presidential election test, your political identity. In the task, you classify words and images into categories using the “K” and “D” keys on your keyboard. For instance for the election, you are asked to focus on one presidential candidate (McCain or Obama) and selections from categories (e.g., a set of concepts, images or words such Happy, Love, Friend, Success)

You rapidly press "K" when faces of the presidential candidate who is selected for focus appears. You also press "K" when items from the category that is selected for focus appears.

You rapidly press "D" when faces of the other presidential candidate appears. You also press "D" for items that are not in the selected category.

If you press the wrong key, a red X appears. You rapidly press the other key to continue.

After another short questionnaire, the results of your test are revealed. Your automatic associations may be described as 'slight', 'moderate', 'strong', or 'little to no preference or difference in association'. Note that how implicit associations fit our actual behaviors is unclear, and needs more research. The findings, however, are revealing and do serve to encourage self-reflection. When we have some measure of our unconscious biases and attitudes, we have a greater opportunity to, if we wish, work to free our overt behavior from our unconscious, automatic responses.
