Americans are optimistic about their eternal destination, with nearly 70 saying they are quite certain or very certain they are going to heaven, and 21 percent saying they are somewhat certain, according to a new report from Baylor University.

Fewer than 10 percent of U.S. adults surveyed expressed a great deal of doubt about their chances of going to heaven, saying they were “not at all” or “not very” certain.

A majority of Americans (52 percent) say they are not afraid of hell, while 48 percent express varying degrees of fear.

Those who say they are going to heaven are less likely to report depression and anxiety. Fear of hell doesn’t necessarily raise the risk of depression, but those who say they are very afraid of hell are more likely to exhibit symptoms of anxiety.

Those who say they are going to heaven are less likely to report depression and anxiety.

Ten percent of Americans say their life has no clear purpose, a response that also correlates to higher levels of depression and anxiety.

In terms of overall happiness, those who say they are on their way to heaven and have clear purpose in life are overwhelmingly the happiest individuals. Those who have little hope of heaven and no purpose are most likely to say they are unhappy.

“While the causality is unclear, mental health consistently predicts positive existential beliefs,” the study concluded. “Philosophical nihilists need not be fighting extreme anxiety, but they probably are.”

Baylor is a private Christian university in Waco, Texas.
