Implicit Association Test

This clip demonstrates the Implicit Association Test (IAT). African American and Caucasian participants take the IAT individually, and in the presence of others.

A show host reveals the participants responses (i.e., preference for whites/blacks) and participants offer their feelings about the test. Do you support the level of deception necessary to conduct the IAT? What pattern of results would you expect if the studys hypotheses and purpose of the study were given to the participants beforehand?
