There were 39 Mormons, 1 by paper and the rest by e-mail, out of 1325 people who responded. It asked various questions about belief in life on other worlds, but mostly if discovery of such life would be damaging to faith. As reported in a New Scientist article, few believe E.T. would damage their own faith, but a larger percent believe that wouldn't be the case for others.
To be fair, there wasn't that much difference between the respondents as to their personal position on discovery of aliens and crisis of faith. All of them had strong numbers in the belief they would not have a major crisis. Mainline Protestants were virtually tied with Mormons, although using the mainline label poses difficulties in interpretation. Even the lowest number among the faithful was above 80 percent in the belief discovery of alien life wouldn't be harmful. Buddhists were the highest in those who didn't believe the discovery of E.T.s would undercut what they believe.
It is when asked about the official doctrines that the numbers become less even. Although still above half for all faiths, only Buddhist respondents had higher numbers than Mormons when asked if the faith tradition itself would be challenged. The survey singled out Mormons in particular as a religion that could survive discovery of alien life on other planets. It reported:
Note how high Mormons score. Many Mormon respondents added comments to the effect that belief in ETI is already a part of Mormon doctrine. "My religion (LDS, Mormon) already believes in extra-terrestrials."
A greater disparity exists between Mormons and other religions when asked if Extraterrestrials would have sharp conflict of beliefs and practices compared to humans on Earth. Almost 30 percent more Mormons than other respondents disagreed that there would be significant differences. It didn't go without notice by those who gave the survey who wondered if incorporation of ETI in doctrine contributed to the responses.
Where does this positive acceptance of life on other world's come from? It is a combination of new revelations and doctrinal speculation. Mormonism can be seen as more than a religion based on a single planet called Earth. It extends The Gospel to both the Cosmic and the Eternal of existence. Critics might see this as "science fiction" rather than religion, but that is no worse than the "fantasy" of pure paranormal or metaphysical belief systems. Mormonism can often be science friendly and rather modern in theory.
