Bob Wright explores an instance when the human tendency "to latch onto evidence consistent with your worldview and ignore or downplay contrary evidence" has an upside:

It means that the regrettable parts of the Koran the regrettable parts of any religious scripture don’t have to matter. After all, the adherents of a given religion, like everyone else, focus on things that confirm their attitudes and ignore things that don’t. And they carry that tunnel vision into their own scripture; if there is hatred in their hearts, they’ll fasten onto the hateful parts of scripture, but if there’s not, they won’t. That’s why American Muslims of good will can describe Islam simply as a religion of love. They see the good parts of scripture, and either don’t see the bad or have ways of minimizing it.

So too with people who see in the Bible a loving and infinitely good God. They can maintain that view only by ignoring or downplaying parts of their scripture.
