The foremost reasons are disbelief both in Joseph Smith as a prophet[6][7] and in the Book of Mormon as a religious and historical document.
[5][8] Reasons for this disbelief include issues with anthropological, linguistic, archaeological, and genetic evidence against the Book of Mormon in the New World.
Also, just 4 percent claimed that a significant reason for apostasy was dissatisfaction with the rules of conduct professed by the LDS Church.
[12] A 2023 survey of over 1,000 former church members in the Mormon corridor found the following top three reported reasons for disafilliation: 1.
[15] Those who adopt humanist or feminist perspectives may view certain Mormon doctrines (including past teachings on the spiritual status of black people, polygamy, and the role of women in society) as racist or sexist.
"[18] Liberal views and political attitudes that challenge this conformity, and occasionally sexual orientation, are cited as reasons for leaving Mormonism.
the LDS Church has become more politically active, particularly with regard to legislation barring civil marriage for same-sex couples.
[20] After their decision to leave Mormonism and the LDS Church, ex-Mormons typically go through an adjustment period as they re-orient their lives religiously, socially, and psychologically.
Family members of some may express only disappointment and sorrow and try to reach out in understanding to their new belief system or lack thereof.
Still, many ex-Mormons have given up spouses, children, and the ability to enter Mormon temples to witness important life events of family members.
[16] One ex-Mormon compared his disaffiliation experience to leaving a cult,[23][non-primary source needed] while others called it close to overcoming mind control[24] or adjusting to life outside of religious fundamentalism.
[32][33][better source needed] The Community of Christ appeals to some disaffiliates from the LDS Church given their related but distinctive histories.
