At a conscious level, Aaron doesn't think he's prejudiced. Yet he automatically feels uncomfortable in situations in which he has to interact with people of different races from his own. Aaron's experience best illustrates the distinction between:.a. social identities and ingroup bias.
b. blaming the victim and hindsight bias.
c. explicit and implicit attitudes.
d. social scripts and scapegoat theory.

Explicit and implicit attitudes  

Explanation:

It is very interesting for us that attitude exists in two forms. The explicit attitude and implicit attitude.  

The explicit attitude: the explicit attitude work at the level of outside. It works on a conscious level. This attitude is deliberate and very easy to self-report.  

The implicit attitude: This attitude occurs at an unconscious level. This occurs involuntarily and it is not known for us.  

Aron is at the level of explicit and implicit level because he does not know that he is prejudiced.
