Dr Gillig Is Worried That When He Asks Participants to Indicate

Dr. Gillig is worried that when he asks participants to indicate on a questionnaire how they feel about members of other racial groups, they will respond in a socially desirable manner instead of indicating how they really feel. If Dr. Gillig uses a bogus pipeline in his research, he is hoping to convince participants

A) that it is not important whether they look good or look bad.
B) he can tell when they are lying as opposed to telling the truth.
C) that their responses are completely anonymous and confidential.
D) he, too, is biased, so they should feel free to admit their own racial biases.
