The Art Freaks also influenced Cady to conform through group unanimity. Both Janis and Damian believed that the Plastics were the cause of their suffering, and because of this, Janis' order for Cady to become a member of the Plastics was achieved. By manipulating Cady into believing that the Plastics were the enemies, Janis and Damian could finally get their revenge. Even though Cady did not know about the Plastics, she had no choice but to follow their beliefs or she would be defeated.

Lastly, group members are more likely to conform when in public than in private. This is evident in the movie when Cady shows the two-sided parts in her. In the group, she is deliberately following the rules and beliefs of Regina, the A-list leader of the clique. However, during their private conversations with the other girls, she is able step aside from being the follower. Clearly, in public, she only has the desire to get along with the “norms” of the group, but in private, she willfully expresses her own opinions to others without feeling rejected and undesirable in front of Regina.

After examining the shocking truth about high school, it is therefore necessary to stop recognizing ourselves as copies of others. Social groups and cliques don't last forever, and sooner or later, everyone will get over high school.
