What negative feature of Jordan Baher's personality revealed when we find out Tom has a woman in New Yord?

Jordan Baker's reaction to the revelation of Tom's affair reveals her **cynicism and jaded worldview**. She's not surprised or particularly bothered by Tom's infidelity; instead, she treats it as commonplace and expected behavior. This demonstrates a certain coldness and lack of genuine emotional engagement, suggesting she's become desensitized to the moral failings of the wealthy elite she belongs to. It reinforces her overall presentation as a detached and somewhat morally ambiguous character.
