By the end of the play, stereotypes are turned upside down. As the play develops, Birling, Gerald, and Eric get weaker, while Sheila gets stronger.

Sheila starts stating her own opinions, not those she is supposed to have - “That’s what’s important - and not whether a man is a police inspector or not.” She’s learnt to think for herself.
