How is anthem by ayn rand and one flew over the cuckoo's nest by Ken kesey connected?

Ayn Rand's "Anthem" and Ken Kesey's "One Flew Over the Cuckoo's Nest" both analyze the human ego.

Rand shows the power of the ego through Equality 7-2521, who realizes at the end that he is his own person, instead of adhering to the rule of collectivism set in his society.

Kesey tests the human ego in "One Flew Over the Cuckoo's Nest" by showing the battle between two huge egos: Nurse Ratched's and Randle Patrick McMurphy's. Both characters want to be the "top dog," and know only one of them will be chosen.

At the end of both novels, the character comes to some sort of realization about his ego (Equality 7-2521, Chief Bromden).
