Views on evolution of religious belief Barrett is described in the New York Times as a "prominent member of the byproduct camp" and "an observant Christian who believes in "an all-knowing, all-powerful, perfectly good God who brought the universe into being," [and] "that the purpose for people is to love God and love each other." He considers that "Christian theology teaches that people were crafted by God to be in a loving relationship with him and other people. Why wouldn't God, then, design us in such a way as to find belief in divinity quite natural?" Having a scientific explanation for mental phenomena does not mean we should stop believing in them. "Suppose science produces a convincing account for why I think my wife loves me—should I then stop believing that she does?"

Why Would Anyone Believe in God? In his book Why Would Anyone Believe in God? he suggests that "belief in God is an almost inevitable consequence of the kind of minds we have. Most of what we believe comes from mental tools working below our conscious awareness. And what we believe consciously is in large part driven by these unconscious beliefs." and "that beliefs in gods match up well with these automatic assumptions; beliefs in an all-knowing, all-powerful God match up even better."
