Solomon Asch Set Up an Experimental Situation in Which Participants

Solomon Asch set up an experimental situation in which participants were asked to identify which of the three comparison lines was identical to a standard line, as shown in the illustration below. His research was designed to answer a straightforward question, namely:

A) How can conflict between groups be created, and how can harmony be established?
B) How is cognitive dissonance created, and how is it resolved?
C) Would people conform to group pressure even if the group opinion was clearly wrong?
D) Would people obey a direct command to hurt another innocent person when doing so violated their own conscience?
