Egon Mayer, a professor at Brooklyn College, published another study confirming that inter-faith couples experience higher divorce rates.
Referring to the case where one spouse abandons their religion and adopts their spouse's faith, he wrote in USA Today: "When you bury something that is really important to you, all you're doing is building up a kind of pressure within the family relationship, which becomes a source of tension, which ultimately becomes a time bomb.
There is often no room to compromise without one spouse giving up some of their beliefs.
Irresolvable conflicts often occur in intra-faith marriages as well.
Bollywood has a lot of dilwale, who took their dulhaniyas away despite facing the big challenge of belonging to different religious backgrounds.
He doubts the accuracy of the Barna poll, noting that "Just saying you are Christian is not going to guarantee that your marriage is going to stay together." One must make a full commitment to God. However, religious beliefs tend to be based on faith.

Scientific beliefs are generally based on observation and experimentation. For most people, their religious beliefs are an accident of birth: those born in Saudi Arabia will almost certainly mature to be Muslim adults; those born in Alabama will most likely become a fundamentalist or other Evangelical Christian.
Whatever religion they grow up with is liable to determine their faith for the rest of their life.
Thus the former can be expected to have an even higher failure rate.
