Why does sighet ignore warnings?

In Elie Wiesel's "Night," the people of Sighet ignore warnings about the impending danger from the Nazis due to a combination of disbelief and denial. They find it difficult to accept that such atrocities could happen to them, thinking that the reports are exaggerated or that the situation will improve. Additionally, their sense of security and normalcy leads them to underestimate the threat, believing that their government and the world would protect them. This collective denial ultimately contributes to their tragic fate.
